Recognising the Marine Heritage of Scapa Flow

Fri, 2017-11-17 10:00

Earlier this year, we were involved with a joint project to survey the German High Seas Fleet in Scapa Flow, Orkney. Historic Environment Scotland is now reviewing the protection of these wrecks of as they are scheduled monuments, and they would like to explore if that continues to be the best way of recognising and protecting this hugely important part of our wartime heritage.

___________________________________

Orkney has one of the most outstanding collections of First World War and Second World War remains, both above ground and under water.

The array of underwater archaeological remains includes wrecks from the scuttling of the German High Seas Fleet in June 1919, two major naval disasters with significant loss of life (the loss of the HMS Vanguard in 1917, and HMS Royal Oak in 1939), and the supply and defence of the Royal Navy anchorage using block ships, barriers, and networks of mobile boom defences.

A major resource for salvage from 1919 to the 1970s, nowadays the wrecks of the German High Seas Fleet are a significant heritage asset, attracting visitors from all over the world and contributing to the economy of Orkney.

Recent survey work by ourselves and our partners on Orkney has shed new light on how much survives underwater. Our research shows that the condition of the wrecks is deteriorating and these important remains will not last forever.

Andrew Fulton, Senior Designations Officer, explains more about the review, “We’d like to talk to everyone who has an interest in Scapa Flow to hear their views about its marine heritage. Scapa Flow is an important harbour and is used by many different communities and we’d like to know more about this too.

“We’ll be in Orkney during the first week of December and I’d really like to talk to as many people with an involvement in Scapa Flow as possible. The feedback we get will help inform how the current protection of the German High Seas Fleet wrecks is working and whether any changes need to be made.

“I’m also looking for views on whether any of the other wartime underwater sites within Scapa Flow merit designation and if, so, what would be the best mechanism to achieve this.”

There are a variety of ways which the public can offer their views. We have an online survey which is open to everyone and can be accessed on our website at historicenvironment.scot/scapa-flow-survey. Andrew will be holding drop-in sessions at three locations in Hoy, Kirkwall and Stromness between 4 and 7 December 2017. Everyone with an interest in Scapa Flow is encouraged to come along and share their views. More details about the drop-in sessions will be available on our website historicenvironment.scot/scapaflow.

Event Details

Monday 4th December – YM Hall, Longhope, Hoy 3:30pm-7:30pm

Tuesday 5th Decmber – Pickaquoy Centre, Kirkwall 4:00pm-8:00pm

Wednesday 6th December – John Rae Room, Old Warehouse Building, Orkney Council, Stromness. 5:00pm -8:00pm

Thursday 7th December – John Rae Room, Old Warehouse Building, Orkney Council, Stromness. 5:00pm-8:00pm

Notes for editors: 

  1. Seven wrecks from the German High Seas Fleet were designated as scheduled monuments in 2001. The scheduling means that visitors can dive on the wrecks on a look but don’t touch basis so long as no damage occurs or objects are removed. Scheduled monument consent from Historic Environment Scotland is required for works to a scheduled monument.
  2. The wrecks of the HMS Royal Oak and HMS Vanguard are designated as controlled sites under the Protection of Military Remains Act 1986. The responsible authority is the Ministry of Defence. Although a hugely important part of the story of Scapa Flow, their status does not form part of this review.

Testing the water with an International Bottom Trawl Survey

Mon, 2017-11-13 10:00

1617S Trawl positions for each core station (solid circle) and alternative/additional positions (empty circles) will be added as time allows.

Duration: 13 November – 3 December 2017

Fishing Gear: GOV Trawl (BT137) and ground gear D (hoppers)

Objectives:

  1. To participate in the ICES co-ordinated western division demersal trawling survey.
  2. To obtain temperature and salinity data profiles at each trawling position.
  3. To collect additional biological data in connection with the EU data collection framework (DCF).

Procedures:

All fishing gear and scientific equipment will be loaded aboard during the landing day of 1517S. Scotia will sail on 13 November and (after all safety drills and shakedown trawl shoot) commence fishing operations the following morning on the stations to the west of the Orkneys.  Weather conditions at the time will determine the exact start area.  Survey schedule and operations will be decided by SIC after daily consultation with Fishing Master and Captain.  A half landing with be made around 23 or 24 November into Greenock or possibly Belfast to exchange staff, but the date and port are to be confirmed once the vessel has commenced the survey.

Trawling:

This is a random-stratified survey design with trawl stations being distributed within twelve predefined strata covering the sampling area. One trawl haul of thirty minutes duration will be made within a radius of five nautical miles of each core positions shown on the attached chart.  If trawling is not possible at the core location then the nearest appropriate secondary/alternative station will be used.  Final trawl locations will be decided after SIC consultations with Fishing Master.  For each haul, the Scanmar monitoring system and NOAA bottom contact sensor will be used to observe and record the performance and geometry of the trawl and trawl doors.

Fish Sampling:

All fish will be treated according to current standard research vessel procedures and additional biological data will be collected as determined by EU data regulation 1639/2001 and 1581/2004.

Hydrography Sampling:

CTD casts will be taken at each trawl station. Please note the thermosalinograph will not be run during this survey.

Meet our scientists – Dr Faye Jackson

Tue, 2017-11-07 10:00

data loggers

Who are you and what do you do?

I am a new employee in the Environment Group at Marine Scotland Science Freshwater Fisheries Laboratory (MSS-FFL). I am currently undertaking large-scale (all of Scotland) spatial data analysis, using R as a GIS, to create national scale datasets of river habitat proxies e.g. elevation, river width, bankside woodland. These datasets are used as inputs for both our national juvenile density and river temperature models and allow predictions to be made for any river location in Scotland. I also contribute to the annual reporting for the ‘Scotland River Temperature Monitoring Network (SRTMN)’ and produce peer reviewed papers, reports and conference presentations. My most recent paper describes our national river temperature model which can simultaneously predict daily maximum river temperature and sensitivity to climate change for rivers across Scotland.Dr Faye Jackson

Why is what you do important?

MSS-FFL have been working for a many years on applied research questions that provide us with the knowledge base to create informed policy and management. Under environmental and climate change I believe this is even more important, allowing us to best manage and protect our rivers and fisheries. The national juvenile density model will allow the further development of assessment tools for salmon populations in Scotland.

What has your career path been – how did you get here?

I have always been interested in the environment and how we can protect it. In addition, I love learning and finding out new things, a career in science allows me to learn and discover every day. I have also been privileged to work with and learn from people from a range of different backgrounds and organisations throughout my career.

I completed a BSc Geography degree at the University of Birmingham specialising in hydrology, climate and environmental management. My undergraduate dissertation was focused on understanding how different water sources (e.g. glacial, groundwater, surface water) influenced river temperatures in the Taillon-Gabiétous catchment in the French Pyrenees. I further specialised in hydrology by completing an MSc at the University of Leeds entitled ‘Catchment dynamics and management.’ I remained interested in river temperatures and for my dissertation looked at the temperature dependence of in-stream respiration in the Ӧdenwinkelkees catchment in the Austrian Alps.

Next, I undertook a PhD with MSS-FFL and the University of Birmingham, funded by a NERC Open CASE studentship. My project focused on the development of novel monitoring and statistical modelling methods to understand and predict why river temperature varies at different locations and at different times. As part of this we designed and deployed the Scotland River Temperature Monitoring Network. I was particularly interested in this project because of the ‘real world’ application that meant that the research was going to be used in the management of Scotland’s rivers and fisheries. After my PhD I applied for the ‘Salmon Assessment Modeller’ post advertised at MSS-FFL and was thrilled that I was successful.

If you weren’t doing this, what do you think you would be doing instead?

I would (hopefully!) be a post-doctoral researcher at a university researching rivers under environmental and climate change (e.g. implications for thermal regime, water quality) and the consequences for fish populations. I would have endeavoured to maintain collaborative links with applied research organisations like MSS-FFL to ensure policy and management relevant scientific output.

What’s your favourite fishy fact?

I don’t have a fishy fact but I do have a temperature logger fact. A Gemini Tinytag datalogger (the loggers we use in SRTMN) can measure temperature every 15 minutes for 339 days and 17 hours before becoming full.

One fun fact about you

I love hillwalking, mountain biking and weightlifting.

At Loggerheads with PAM

Mon, 2017-11-06 10:00

Duration: 6-13 November 2017

Gear: Sub-surface passive acoustic monitoring (PAM) moorings.

Objectives:

  1. To retrieve a previously deployed series of moorings comprising acoustic release systems (eight subsurface acoustic release moorings) and the acoustic recording devices attached to them (eight C-POD and three Loggerhead broadband units). Nine moorings were deployed originally however, one of these (Soay) has already been recovered.
  2. To deploy a series of moorings comprising acoustic release systems (six subsurface acoustic release moorings) and the acoustic recording devices attached to them. Each mooring will have a C-POD and a Loggerhead broadband unit attached This west coast background noise and marine mammal monitoring deployment is part of the COMPASS project. Tables 1 and 2 (below) give the locations for recovery of the moorings deployed in August 2017 during survey 1817H as well as the locations for the further deployments to be completed during survey 1917A.

Procedure

Alba na Mara will sail on the morning of 6 November and make for the first mooring position. The ultimate order in which the moorings are deployed will be dictated by the weather forecast and the likely shelter that can be sought along the west coast.  Accurate position records will be kept detailing where the moorings are eventually placed as this may differ slightly from the planned position.

Maximising the benefits of future large scale tidal and wave energy developments

Fri, 2017-11-03 10:00
Wave energy array layout

Wave energy array layout

Marine renewable energy is an important component of the Scottish Government’s vision for the future and will help the government reach its climate change objectives.

In response to this, a three-year project, EcoWatt2050, was created to investigate how we can ensure that the benefits of future large scale tidal and wave energy developments can be maximised, whilst minimising the environmental impacts and ensuring that these meet the legal criteria established by European law.

The project was established through Marine Alliance for Science and Technology for Scotland (MASTS) and funded by the Engineering and Physical Sciences Research Council (EPSRC). It was led by Heriot-Watt University, in partnership with the Universities of Edinburgh, Aberdeen, Strathclyde, and the Highlands and Islands, Swansea University, the National Oceanography Centre (NOC), the Scottish Association for Marine Science (SAMS) and Marine Scotland Science (MSS).

By 2050, the natural conditions in Scottish seas will have changed due to climate change and EcoWatt2050 aimed to consider these changes and compare them with the changes predicted due to large scale marine renewable energy. The research had been specifically designed to respond to questions:

  1. How can marine planning be used to lay the foundation for the sustainable development of very large scale arrays (developments) of marine renewable energy devices?
  2. What criteria should be used to determine the ecological limits to marine renewable energy extraction, and what are the implications for very large scale array characteristics?
  3. How can we differentiate the effects of climate change from energy extraction on the marine ecosystem?
  4. Are there ways in which marine renewables development may improve or exacerbate the predicted effects of climate change on marine ecosystems?

EcoWatt2050 modelling scenarios

A number of areas around Scotland were identified, using a marine spatial planning process, as suitable for tidal and wave energy expansion. This process took into account the best available natural resource for renewable energy, as well as other users of the sea such as oil and gas, fishing and tourism. These identified areas that were used in the project modelling scenarios as the locations of large arrays.

Tidal energy extraction

Using a newly developed hydrodynamic model of Scottish Shelf Seas (the Scottish Shelf Model), changes to oceanographic conditions, caused by energy extraction at both national and local scales, were able to be predicted. Changes to tidal elevation, marine currents and ocean stratification patterns due to both climate change and the effect of large scale tidal arrays could also be simulated, although the tidal array scenarios that were modelled were hypothetical examples, and the arrays of tidal turbines that were used were larger than those being deployed today, but are likely to be common place in 2050.

Wave energy extraction

Hydrodynamic changes due to wave energy extraction was also modelled, in an area off of the west coast of Orkney, using two types of wave energy devices (constructed as large arrays). The modelling allowed factoring in changes to wave height, velocities at the surface and at the seabed, wave front power and also wave period and direction.

Both present and future climate conditions were also investigated in order to assess the relative impact of large scale wave energy extraction and climate change.

Overall Conclusions

The key finding of the project was that overall impacts due to climate change for both the physical and ecological environment are an order of magnitude higher than for renewable energy arrays. The project summary booklet which provides an overview of all the research carried out is available for download from the MASTS website and the Marine Scotland Information project page for EcoWatt2050 will contains metadata for the project outputs and links to the data.

Acknowledgements

The EcoWatt2050 Consortium gratefully acknowledges financial support for this work from the EPSRC Grand Challenge II award (EPSRC Grant Ref: EP/K012851/1), and contributions from MSS and MASTS.

Getting a good grounding with the Northeast Atlantic

Wed, 2017-11-01 10:00

Survey coverage across the Northeast Atlantic by the surveys available in the data product (The Spanish Surveys are not available online at present)

Marine Scotland Science has just released new Groundfish Survey Monitoring and Assessment data for the Northeast Atlantic Area, which includes fish abundance and biomass at length information for all the species caught during the surveys (details in the table below).

With growing interest in understanding, assessing and managing the ecosystem in a more holistic way, having reliable data is key. Although this newly released data had already been collected by the various marine institutions within Europe and stored with the International Council for the Exploration of the Seas (ICES) in their database portal (DATRAS), in some cases sample information was missing or incorrect.  Knowing that this information is a key part of understanding the broader fisheries picture in European waters, because groundfish surveys provide information about the abundance for species of commercial value, which in turn support the stock assessments used in fisheries management, MSS took on the role of taking the raw data, checking it and providing a quality assured product for use in Marine Strategy Framework Directive (MSFD) assessments.

Led by Marine Scotland scientist Dr Simon Greenstreet, all of the European groundfish survey data collected by member countries of ICES have been subjected to a formal quality assurance process to ensure that they are robust. The resulting products contain a total of 41,394 sampling stations and 4,574,975 biological records, spanning from the North Sea to the Gulf of Cadiz with temporal coverage of up to 35 years in some areas.

We would like to extend our thanks to the ICES Secretariat, ICES Data Centre and the wider ICES community, particularly the European Marine Institutions and the scientists who made this project possible.

Glasgow welcomes the EU Atlantic Stakeholder Conference

Thu, 2017-10-26 10:00

Registration is now open for the conference and workshops for the annual Atlantic Stakeholder Conference, which  will take place in Glasgow on 8 November 2017 with a theme of ‘Regeneration across Generations’ and a focus on creating socially inclusive and sustainable models of regional development.

This priority of the EU’s Atlantic Strategy and Action Plan will bring together representatives from each of the five EU Member States bordering the Atlantic Ocean: the UK, Ireland, France, Spain and Portugal. The event is jointly hosted by the European Commission and the Scottish Government and provides a platform for sharing experiences and expertise, finding partners for future projects and funding opportunities for innovative ideas.

Social inclusion in peripheral and coastal communities is a key Scottish Government policy and Fergus Ewing MSP, Cabinet Secretary for the Rural Economy and Connectivity, will welcome delegates as part of the opening plenary session. “Scotland is delighted to host our Atlantic friends and neighbours in a city that embodies the challenges and opportunities offered by regeneration and social inclusion.  Our Economic Strategy addresses the diversity of activities in a shared marine space but identifies the connections between them and the potential for sustainably managing fragile resources through a process of investment, innovation and tackling inequality, where it still exists.”

The event will enable social innovation to be considered as an effective mechanism for the sustainable, inclusive and smart development of the Atlantic Ocean area. Delegates will participate in plenary sessions and parallel workshops covering diverse topics including gender equality in the maritime economy and collaborative approaches to Blue Growth, such as through the Year of Scotland’s Coast & Waters in 2020.  In recognition of some of the most recent successful projects stimulating the blue economy in the Atlantic area, the 2017 Atlantic Project Awards will also be presented during the event.

Notes to Editors

The Atlantic Strategy Stakeholder Conference will take place at Strathclyde University’s Technology and Innovation Centre on 8 November 2017. Glasgow beat competition from Cardiff and Belfast to host this prestigious event, which is held under the UK Chairmanship of the Atlantic Strategy.

In addition to Fergus Ewing MSP, key speakers at the event are:

  • Councillor Eva Bolander, the Lord Provost of the City of Glasgow
  • Mr. Karmenu Vella, European Commissioner for Environment, Maritime Affairs and Fisheries (video message)
  • Councillor Jerry Lundy, Member of the EU’s Committee of the Regions

The EU Atlantic Strategy is one of five similar initiatives run by the European Commission, addressing key issues and challenges to sustainable economic growth, social cohesion and environmental protection in Europe’s major sea basins: the Atlantic Region, the North Sea, the Baltic Sea, the Black Sea and the Mediterranean. The Atlantic Region includes EU Overseas Territories such as Madeira, the Azores and Canary Islands and French Guiana.

The Atlantic Strategy has four themes:

  • Promote entrepreneurship and innovation
  • Protect, secure and enhance the marine and coastal environment
  • Improve accessibility and connectivity
  • Create a socially inclusive and sustainable model of regional development.

The Atlantic Strategy and Action Plan’s objectives are in line with the EU’s ‘Blue Growth’ initiative, which is the contribution made by maritime sectors to the overall goals of the Europe 2020 strategy for smart, sustainable and inclusive growth. The Strategy and Action Plan have just gone through their mid-term review: distinguished speakers from the Atlantic coastal countries and EU officials will recall the milestones of maritime cooperation in the Atlantic and set the scene for the thematic sessions.

Scottish involvement in this event has been coordinated by the Scottish Coastal Forum, working in association with Marine Scotland. For further details, please contact Rhona Fairgrieve, SCF Manager, on 0131 244 2284 or rhona.fairgrieve@gov.scot.

Meet our scientists – Dr Ian Davies

Tue, 2017-10-24 10:00

Dr Ian DaviesWho are you and what do you do?

I am Ian Davies, and I am Programme Manager for the Renewables and Energy Programme. There are two Groups in the Programme; one whose main job is to act as advisers to the Department for Business, Energy and Industrial Strategy (BEIS) on chemical discharge from the offshore oil and gas industries, the other which provides advice to the licensing authorities (Marine Scotland (MS) Licensing Operations Team, and D Energy Local Energy Consents Unit) on environmental aspects of renewable energy (wind, wave and tidal), and undertakes supporting research.  We have active research interests in all parts of the Programme, an increasing number of PhD and MSc students, a variable portfolio of projects that we help commission from external providers, and we are partners in an increasing number of EU-funded projects. My job is to provide an environment in which all these competing calls can be met.

At a more corporate level, I chair the Marine Scotland Science (MSS) Health and Safety Committee, and take an active interest in training and staff development.

Why is what you do important?

What we do helps Scotland to make the most of its energy resources while maintaining high environmental quality. Renewables are part of the global answer to controlling climate change through decarbonisation of the economy.  We are part of this huge global endeavour, and we can see the direct consequences of what we do in the construction of wind and tidal energy farms (wave will come later!).  North Sea oil production is gradually decreasing, and our advice has contributed to keeping the North Sea free from gross pollution despite being the location of what continues to be the largest industrial sector in Scotland.

What’s your career path been – how did you get here?

I came to the Marine Laboratory in Aberdeen direct from a geochemistry PhD in Edinburgh in 1974 as a Scientific Officer. I joined the Chemistry Section which was in the process of expanding from its base in nutrient analysis into metallic contaminants, such as mercury and cadmium in fish and shellfish.  We had four research vessels in those days, and also large experimental programmes at Loch Ewe and elsewhere, so I spent quite a lot of time away from the lab.  In the mid-80s, I had a three year assignment as Assistant to the Coordinator of UK Fisheries Research and Development on temporary promotion to Principal Scientific Officer (PSO), which greatly broadened my views of the work done in UK fisheries laboratories. I came out of that responsible for environmental aspects of aquaculture, including testing of sea lice treatments.  Environmental effects of contaminants dominated the next years, with roles as member and chair of ICES Expert Groups and OSPAR Committees.  Everything was ticking over just fine until about 2008 when I was asked to translate a Strategic Environmental Assessment for marine renewables into a research and management programme. For a while, I was a Programme of one person, responsible for both renewables and marine planning!  Renewables was interesting, so I stayed and have built up a larger team over the last few years to address Scottish Government objectives for renewables.

If you weren’t doing this, what do you think you’d be doing instead?

I would be retired! However, I would miss working with MSc, PhD students and younger members of staff, assisting them to mature and achieve. I would be able to spend more time on the small charity that my wife Ruth and I run, primarily working in Romania.

What’s your favourite fishy fact?

Not very fishy, but definitely marine and very important for Scotland and renewables. Offshore wind energy is now significantly cheaper than nuclear energy.

And one fun fact about you?

I still try to play table tennis and badminton. I am waiting for someone to offer a quiet word of advice that really I am past it!

Where do fish live?

Mon, 2017-10-23 10:00

Last week,  our scientists were involved in a programme aimed at providing fine-scale data on the habitat associations of cod, haddock and whiting at a key period in their life history – following the transition from pelagic to demersal habitat.

The programme also provided them with an opportunity to add to the fish trap and fixed-position baited underwater video data obtained earlier in the year, which is used to further inform 0-group distribution models and samples for otolith-based growth and survivorship analysis.

During the programme, which was conducted on board the MRV Lady Nicola, scientists deployed fish traps over various habitat types within and around the Small Isles MPA and also synchronously deployed baited remote underwater video camera frames fitted with twin cameras calibrated for post-survey photogrammetric analysis.

Fish traps were deployed at the start of each working day, in fleets of 3, 2 and 2 traps, to be picked up again following a minimum soak time of 6 hours. The deployment location (GPS latitude and longitude), soak time, and bait type and quantity were recorded and captured fish released from the trap, with measurements of total length (to 1 cm) and weight (to 0.01 g).  Otoliths from gadoid species (cod, haddock, and whiting) were also extracted to establish age, with tissue from a subsample of the catch and stored in ethanol for genetic analysis. Time was set aside during each day to collect fresh bait.

Both underwater video camera frames were deployed at distances sufficient to avoid any interaction with the fleet ground gear (recommended minimum 500 m between deployments). Two cameras oriented ±6° perpendicular to the frame base were synchronously recording high definition video for a nominal period of 1.5 hours.  Footage was then downloadeded to external media at the end of each working day.  Species type, relative species densities (MaxN) and substrate type (assessed visually) were classified post-survey.

Jointly Surveying Marine Protected Areas

Fri, 2017-10-20 10:00

Figure 1: Location of Marine Protected Areas to be visited by 1517S survey.

Duration: 20 October – 9 November 2017

Fishing Gear

  • TV drop frame and wiring harness
  • TV sledge and wiring harness
  • Valeport mini-CTD
  • 0.25m2 USNEL BSL Box core
  • 0.1m mini Hamon grab
  • 0.1m Day Grab (backup)
  • 0.1m Van Veen Grab (backup)

Background

Marine Scotland Science (MSS) and the Joint Nature Conservation Committee (JNCC) will undertake an offshore seabed survey in the Northeast Faroe-Shetland Channel (NEF hereafter), Scottish Nature Conservation Marine Protected Areas (NCMPA) and the Wyville Thomson Ridge (WTR) on the Marine Research Vessel (MRV) Scotia (Figure 1).  Habitats within the NEF MPA vary down the slope with the descent into deeper (arctic) water.  In particular the FSC survey will focus on deep-sea sponge aggregations that are expected to be found between depths of 400 and 600 m.  The MPA represents the variation in sand, mud and gravel habitat types present, and the animal communities they support.

Objectives

Figure 2: Sampling boxes A, B and C with chariot tow start and end points for North-east Faroe-Shetland Channel NCMPA.

  1. Conduct a Type 1 (Henry and Roberts, 2014) monitoring survey of the NEF NCMPA focusing sampling within boxes positioned to allow for sampling to occur across the range of depths, biological zones and proposed management measures at the site. This will include visual (camera) and physical (box corer or grab)sampling (Figures 2 and 3). Visual data will be collected from areas understood to contain deep-sea sponge aggregations within the site boundary (Box A) and from adjacent areas outside the site (Boxes B and C) along the same depth contours. Physical samples will be obtained for further for further characterisation of the wider seabed within the site (Box D). Environmental data will be collected during visual sampling.

    Figure 3. Physical sampling stations (60) generated for NEF NCMPA in Box D (purple). Note 30 of these stations are considered core with a further 30 contingency only.

  2. Conduct a Type 1 monitoring survey of the WTR (Figures 4 and 5) focusing on sampling within boxes A, B and C which are positioned to allow for sampling to occur across the range of depths, biological zones and proposed management measures at the site. The focus will be on visual (camera) methods only. Environmental data will be collected during visual sampling.

Narrative

After completion of safety drills and exercises, there will be shakedown deployments of the chariot, box corer and Harmon grabs.  Thereafter, Scotia will proceed north towards the NEF area.

In boxes A-C four long (~3km) chariot tows (Figure 2) will be used to characterise the epifaunal communities present within the boxes and 16 short (200m) drop-frame camera transect stations (not illustrated) will facilitate collection of high definition video and still images. In box D 60 stations have been generated of which a core 30 will be prioritised for physical sampling.  Initially the vessel will sample with chariot and box core/Harmon grab in alternate 12 hour shifts until all chariot runs are completed.  Thereafter, sampling may concentrate on the dropframe runs until these are completed with the remainder of the time used for remaining box core/Harmon grab deployments.  Where time permits sampling of suitable sponge aggregations may be undertaken in boxes B or C using box core or Harmon grab.

Figure 4. WTR sampling box A and drop-frame stations.

Upon completion of work at NEF the vessel will proceed to WTR and visually sample in box A using the drop frame using a systematic grid approach (Figure 4). Sampling will also focus on the area within and adjacent to a proposed static gear closure to determine the distribution and extent of Vulnerable Marine Ecosystems (VMEs), including sponges and corals (Figure 5).

Figure 5. WTR sampling boxes B and C along with existing data and drop-frame stations.

Tables 1-3 show positional information for the visual aspects of the survey. Positions of physical sampling stations and all contingency stations will be available to MRV Scotia.

For the purposes of this survey the NEF will be prioritised over the WTR and visual sampling will be prioritised over physical sampling.

Contingency plans in NEF to undertake further physical sampling in box D where moderate conditions preclude camera work. In WTR contingency for moderate weather is sampling with Harmon grab at a predefined location to the west of the site.  In both cases contingency includes transit to already identified inshore survey locations in the event of prolonged unworkable conditions.

A full and detailed survey plan and scientific rationale will be presented at the pre-brief meeting, before the beginning of the survey.

Clyde Herring Acoustic Survey

Wed, 2017-10-18 10:00

Duration: 20 October – 3 November 2017

Figure 1: Track executed by MRV Alba na Mara on the Clyde Herring Acoustic Survey October 2012.

 

Sampling Equipment: PT154, CTD

Objectives:

  1. To conduct an acoustic survey designed to survey both the open and enclosed areas of the Clyde to ultimately provide an estimate of the abundance and distribution of herring and sprat.
  2. To obtain samples of herring and sprat for biological analysis, including age, length, weight, sex, maturity and ichthyophonus infection.
  3. All other species caught will be measured for length and weight to establish a length weight relationship.
  4. CTD profiles will be taken at the end of each trawl.

Procedure:

The survey will be carried out within an area bounded by approximately 55°N to 56°N and 04° 40’ W to 05° 40’ W. Echointegration will be carried out at 38, 120 and 200 kHz.  Data gathered in the hours of darkness will not be used for stock assessment.  Trawling operations will be carried out as and when marks are identified.  Otoliths will be collected from a sub-sample of the herring and sprat to determine age.  The maturity state and. presence of Icthyophonus infection will also be recorded.

A CTD profile will be taken at the end of each trawl.

The track will be similar to that of previous surveys (Figure 1).

TSG data will be gathered during the survey.

The survey will involve following a pre-set survey pattern, at a steaming speed of 8 knots.

ECOMMAS makes some more noise

Tue, 2017-10-17 10:00

Figure showing location of deployment stationsThe East Coast Marine Mammal Acoustics Study (ECOMMAS) is a long-term, on-going study into how underwater noise generated by offshore industry impacts the distribution of dolphins and porpoises in Scottish coastal waters of the North Sea. Acoustic recorders (C-PODs and SM2Ms) are deployed at 30 sites across 10 locations along the east coast, extending from Latheron in the outer Moray Firth to St Abbs in Berwickshire. They record underwater noise and count echolocation clicks to detect dolphins and porpoise. They have been deployed to collect data over a 7 month period, beginning in Spring, since 2013.

This work will allow Marine Scotland Science to gain a clearer picture of the distributions harbour porpoise and dolphin species, to help us understand whether major construction projects have any effect on this.

Marine Scotland has recently published the 2013-16 CPOD data, presented as detection-positive days (DPD) and detection positive hours (DPH) for porpoise and dolphins species. The data has also been uploaded into Marine Scotland’s National Marine Plan Interactive (NMPi) website where graphical representations of detections for each year, across both species, can be seen.

Crab and Lobster Fisheries in Scotland: Results of Stock Assessments 2013 – 2015

Mon, 2017-10-16 10:00

CrabToday, Marine Scotland published the latest in its Scottish Marine & Freshwater Science series – Crab and Lobster Fisheries in Scotland: Results of Stock Assessments 2013 – 2015.

Crabs and lobsters are important species for the Scottish fishing industry. Although the total quantity landed is small relative to finfish landings, crab and lobster attain high prices. In 2015, the combined crab and lobster species landings of 16,000 tonnes had a value at first-sale of over £29M (Scottish Government, 2016). The fishery is long established and was traditionally an inshore mixed species creel fishery, however, improved technology and the ability to store and transport live animals in the 1980s led to the development of an offshore fishery for brown crab. This, and the demand from new markets, has resulted in a substantial increase in the Scottish landings over the last thirty years.

The most important crab species landed in Scotland, in terms of weight and value, is the edible or brown crab (Cancer pagurus) which is found all around the Scottish coast. The second most important by landed weight is the velvet swimmer crab (Necora puber). Velvet crabs are often caught in the inshore creel fishery with lobster and brown crab and very few fishermen fish solely for velvet crab, although some target the species at certain times of the year.

The lobster most commonly landed in Scotland is the European lobster (Homarus gammarus), a valuable species for which seasonal prices can be as high as £20 per kg at first sale. Other lobsters landed include the spiny lobster or crawfish (Palinurus elephas), squat lobsters (family: Galatheidae) and the Norway lobster (Nephrops norvegicus), also known as langoustine or Nephrops.

Creel fishing in Scotland continues today as an inshore fishery around most of the Scottish coast, with vessels setting their gear within a few miles of the shore. The fishery is typically a mixed species fishery with both crab and lobster being targeted, albeit with some seasonal and regional variation. Most creel vessels are small, less than 10 m in length and with only one or two crew, and make short day trips to haul creels. However, a number of larger vessels now take part in an offshore fishery to the north and west of Scotland.

The report presents the results of Scottish regional brown crab (Cancer pagurus), velvet crab (Necora puber) and lobster (Homarus gammarus) stock assessments carried out by Marine Scotland Science (MSS) based on length cohort analyses (LCAs), which is applied to commercial length frequency data for the period 2013-15.

Predicting the impact of underwater noise on marine mammals

Fri, 2017-10-13 09:00

DolphinsMarine mammals, such as seals and dolphins, are sensitive to underwater noise and other disturbances which can affect their ability to forage or communicate. Our understanding of the effects of these pressures on marine mammal, and of how to assess and quantify potential impacts on populations, is rapidly evolving.

One tool that can be used to assess potential impacts of disturbance on marine mammal populations is the iPCoD (Interim Population Consequences of Disturbance) model. It was developed by SMRU Consulting and the University of St Andrews in 2013 and released by Marine Scotland in 2014.  It considers the consequences of disturbance, hearing damage or collisions that might result from the construction or operation of offshore renewable energy devices.  Marine Scotland is happy to announce that in keeping with our evolving understanding of effects of underwater noise, and how to assess them, we have recently published an update to the iPCoD model.

The newly released iPCoD model (version 3) is an update developed by SMRU Consulting, the University of St. Andrews, and Marine Scotland.

This update mainly contains improvements and developments such as:

  • improvements to run-time
  • flexibility in the way the effects of the persistence of disturbance are modelled
  • provision to specify different effects for animals close to the noise source and those further away
  • simplified data entry and a number of other smaller improvements

The download file contains the R code required to run the model as well as a new helpfile.

Model Movements

Thu, 2017-10-12 11:00

This morning, Marine Scotland has published a report on approaches for modelling harbour seal movement. This type of information is important because it may be able to help predict the consequences of environmental change, such as the establishment and operation of marine renewable energy, on the distribution and movement of seal populations.

The work, undertaken by the Sea Mammal Research Unit (SMRU) at the University of St Andrews, investigated two modelling approaches:

  • An Inter-Haulout Transition Rate (I-HTR) model, which uses data from tagged seals to quantify the frequency of movement between haulout sites.
  •  A prototype Individual Based Model (IBM), which extended the work of the I-HTR to consider the causes of movement.

Both models used telemetry data from harbour seals tracked in the Orkney and Pentland Firth area. Where the I-HTR made inferences about the frequency of movement of the local population of seals, as well as movement of the larger population, it did not consider the causes of movement and was unable to predict the consequences of environmental change.

However the IBM Model, although in the very early stages of development, monitored activity over a number of weeks and demonstrated the ability to capture the basic movement patterns and behaviour that are observed in harbour seal telemetry data.

Clyde 2020 – Sampling the sediment

Wed, 2017-10-11 10:00

Figure 1. Map showing the proposed sampling stations (Black points) and stations sampled in April 2017 (grey points) in the Firth of Clyde superimposed over gridded stratified clusters of high and low mud content (>25%) and depth (50m).
E_LM_LD: Low Mud / Low Depth, F_LM_HD: Low Mud / High Depth, G_HM_LD: High Mud / Low Depth, H_HM_HD: High Mud / Low Depth.

Duration: 13-17 October 2017

Fishing Gear:

  • Craib corer
  • Day Grab – 0.1m2
  • Autosieve (0.5mm & 1mm mesh sieves)
  • CTD

Objectives:

  1. To map spatial distribution of sediment characteristics, infauna composition, pore-water nutrients and organic matter content within the inner Firth of Clyde, Clyde sea lochs and Clyde Estuary.
  2. To map the relationship between mean particle grain size and permeability/porosity in the Firth of Clyde.
  3. Determine how relationships among sediment properties and sediment nutrient content are modified by natural disturbance, fishing activity and bioturbation potential.

Procedure:

Figure 1 shows the proposed stations from which grab and core samples of seabed sediment will be collected. Stations are stratified according to depth and sediment mud content (see Figure 2).

Figure 2: Maps of the Firth of Clyde superimposing proposed sampling stations (Black points) and stations sampled in April 2017 (grey points) over spatial distributions of fishing effort (number of vessels) for vessels < 15 m. ScotMap data.

Stations in the Clyde Estuary and in the vicinity of the isles of Bute and Cumbrae will be sampled Day 1 (13 October). Subsequent sampling days will then focus on sampling stations south of Bute and east of Arran, and stations west of Bute and in Loch Fyne.  It is expected that ~ 5 stations will be sampled per day.

The survey anticipates equal emphasis on grab sampling and coring. The target would, therefore, be six cores, two grab samples and one CTD profile from each station.

Grab sampling

Two replicate grab samples will be collected per station. Subsamples will be taken from each grab samples and frozen for subsequent laboratory analysis of grain size distribution, % TOC/TN, sediment Chlorophyll-a & Phaeophytin-a content.  The remaining sample will be sieved through a 0.5 mm mesh and the retained material preserved in 4% Saline Formaldehyde for subsequent laboratory extraction and identification of benthic invertebrates.  Samples will augment data from SEPA and SNH, and provide estimates of benthic biomass for hitherto unsampled areas.

Coring

Coring may not be possible in sediments with low mud content and high tidal currents. Hence, coring will be attempted until three hours elapse or six cores are collected.

Assuming the collection of six replicate cores per station, three will analysed for permeability, porosity and grain size distribution, and three for pore-water nutrients (Ammonium, Phosphates, Silicates and Nitrates), with the extraction of four pore-water nutrient samples and 3 measurements of porosity per core.

Sampling 20 stations would yield:

  • (Core samples from 10 stations) 60 cores
    • 30 overlying water nutrient samples
    • 90 pore-water nutrient samples
    • 30 overlying water Chl-a and Pheo-a
    • 30 measurements of permeability
    • 90 measurements of porosity
    • 180 measurements of PSA
  • (Grab samples from 20 stations) 40 grab samples
    • 40 PSA samples
    • 40 %TOC/TN samples
    • 40 Sediment Chlorophyll-a and Phaeophytin-a content
    • 40 Benthic infauna samples

Ancillary Information – Chemicals to be Carried

  1. 4% Formaldehyde – Seawater solution (~20L) – 40% aqueous Formaldehyde is diluted with seawater and stored above 5oC.
  2. Di-sodium tetraborate 10-hydrate GPR (Borax) – Added at a concentration of 1g / 500ml of formosaline. Serves to prevent dissolution of bivalve shells by neutralising acidity.
  3. Acetone.
