Rockall and Helen's Reef - high resolution multibeam echosounder bathymetry

Marine Scotland Information NMPi icon

High resolution bathymetry data of Rockall and Helen's Reef collected 2011-2012 as part of the ROAME Offshore Fisheries and Conservation (OFFCON) project. Rockall, a tiny island just 19 metres high, sits on the very extremity of Scotland’s marine environment. Some 180 miles due west of St. Kilda, it is buffeted year round by the extreme winds and swell that the North Atlantic weather generates. As such, it is Scotland’s only truly offshore shallow water ecosystem. The islet of Rockall is actually the only part of vast plateau of submerged continent that remains above sea-level.

 

 

Fishing Intensity - UK Fishing Intensity Associated with Oil and Gas Pipelines (2007-2015) - Demersal Trawls

Marine Scotland Information NMPi icon

The layers provide information on the intensity of mobile fishing associated with Oil and Gas pipelines and cables. Each layer was created by calculating the total number of fishing tracks in 1 km by 1 km squares along the length of each pipeline for four gear categories (see Rouse et al 2017). Fishing tracks were recreated for UK vessels greater than 15 m in length between 2007-2015 operating mobile demersal gear (otter trawls, pair trawls, beam trawlers and dredges) using vessel position data extracted from the Vessel Monitoring System.

The layers can be used to aid the pipeline decommissioning process, including assessing the potential impacts and risks of different decommissioning options to commercial fisheries and informing the frequency of post-decommissioning monitoring according to level of fisheries interaction. The layers can also inform risk modelling for operational pipelines.

This layer depicts fishing intensity by Demersal trawls and uses the time-aware functionality to filter by year.
