The areas covered include the Hebridean shelf slope, adjacent offshore banks and seamounts as well as the Faroe- Shetland Channel and Wyville Thomson Ridge.

All the surveys referenced within this dataset took place on the FRV Scotia 2 (1996 - 1997) or MRV Scotia 3 (1998 - 2019). The surveys making up the dataset are the MSS Deepwater Slope Survey (Deepwater Time Series), this contains data from surveys undertaken between 1998 - 2019 with trawl sample data collected predominantly within the Hebridean Slope region although also from offshore seamounts and banks as well as the Faroe -Shetland Channel and Wyville Thomson Ridge. It is undertaken in September. In addition to these are several other standalone, exploratory and project specific deepwater surveys where data have also been extracted from. These surveys traditionally had more of a focus on the offshore seamounts and banks (OFFCON Rockall, Exploratory Seamount) and in terms of their calendar period were not necessarily restricted to the 3rd quarter as is the case with the timeseries surveys. All of these surveys utilised the BT184 MSS deepwater trawl. The deployment and catch processing/sampling methodology employed on all these surveys is consistent and documented in the MSS Deepwater Trawl Survey Manual. This can be accessed by accessing the link to the following Marine Scotland Science Report 03/10: Deepwater Trawl Survey Manual http://www.scotland.gov.uk/Resource/Doc/295194/0103756.pdf This dataset also contains data from the MSS Monkfish (anglerfish) surveys (SIAMISS) undertaken on Scotia. These surveys span the period between 2008 - 2016 and are predominantly (although not exclusively) from the Rockall Bank/Slope and during the month of April and has a maximum depth range of around 1000m. The trawl used on this survey is the Jackson Monkfish trawl (BT195) and although slightly larger in terms of its opening (as compared to the BT184) overall it is very similar to the MSS deepwater trawl variant currently used with 16 inch rockhoppers and cutaway lower wings.
