Non native species - Sargassum muticum - Wireweed - August 2012 (restricted zoom)

Marine Scotland Information NMPi icon

Sargassum muticum, (wireweed), is an invasive non-native brown alga originally from Japan but now found extensively in Europe and North America. It is a fast-growing species able to form dense stands where conditions suit and by virtue of its life-history traits, is ideally suited to spread rapidly once established in a new region. Fronds of the alga readily become detached and can then disperse via natural drift. Crucially, these fronds can remain reproductively active for several weeks enabling dispersal over a wide area. S. muticum was first recorded in the UK in 1973 but did not reach Scotland until 2004 when it was found in Loch Ryan. It has subsequently spread up the west coast of Scotland. This dataset was produced by Scottish Natural Heritage (SNH).

Marine Scotland Seabed photo locations

Marine Scotland has undertaken survey and monitoring work to provide expert scientific and technical advice to support Scottish Government policies and regulatory responsibilities. The videos and images produced during these seabed surveys are useful for a wide range of activities and research.  These datasets have been georeferenced and mapped using Google Earth. This layer depicts the seabed video track locations.

National Tide Gauge Network (Scotland) - Permanent Service for Mean Sea Level (PSMSL)

The UK National Tide Gauge Network is owned and operated by the Environment Agency on behalf of the UK Coastal Flood Forecasting service (a partnership between the Environment Agency, Natural Resources Wales, the Scottish Environment Protection Agency and Northern Ireland Department for Infrastructure – Rivers. It records tidal elevations at 44 locations around the UK coast. Data is made available in near real time with measurements reported every 15 mins. The measurements provide mean sea level within each 15 min window and are reported both relative to local datum (unit m) and relative to the Ordnance Datum at Newlyn (unit mAOD).

OSPAR - Riverine Input Monitoring Points

The OSPAR Commission for the Protection of the Marine Environment for the North East Atlantic plays a major part in safeguarding and conserving the habitats and species of the marine environment.

The Scottish coastline was divided into 7 regions (the River and Island Purification Boards) at the time that the Scottish monitoring network was developed to report the amalgamated nutrient loads and inputs for the OSPAR-RID (Riverine Inputs and Direct Discharges) programme. This layer displays the location of riverine inputs monitoring points. For more information see - Riverine Inputs and Direct Discharges (RID) (https://www.ospar.org/content/content.asp?menu=00200304000109_000000_000000).

The Comprehensive Study on Riverine Inputs and Direct Discharges (RID) aims to assess the input of selected contaminants to the OSPAR maritime area and its regions which are carried via rivers into tidal waters or are discharged directly into the sea (for example through sewage pipelines or activities like aquaculture applying substances directly in the sea). The RID Study currently focusses on mandatory monitoring and reporting of the concentrations and loads of the metals cadmium, copper, lead, mercury and zinc, the organic pollutant lindane, nitrogen and phosphorus species and suspended particulate matter. Monitoring of PAHs, mineral oil, PCBs and other hazardous substances, especially organohalogens, are recommended for voluntary monitoring.
