The Scottish Ocean Climate Status Report 2016 described the status of the physical conditions in the seas around Scotland in 2016 and examined the variability and trends in the last decade, and further into the past. Figures showing time series of a number of variables were extracted fromthis report and added as tooltips to the the Scottish Marine Regions, the Charting Progress 2 Regional Seas, and four water masses (North Atlantic Water, NAW; Modified North Atlantic Water, MNAW; Fair Isle Current, FIC and Cooled Atlantic Waters, CAW)

Deep Sea Sharks - Longnose velvet dogfish (Centroselachus crepidater) - distribution of abundance across the survey area

Marine Scotland Information NMPi icon

Data from a scientific deep-water trawl fisheries survey in the north-east Atlantic were analysed to determine the spatial and bathymetric distribution of elasmobranch species and assess the change in relative abundance over the period 1998–2013. During this period, commercial fisheries for deep-water sharks went from being entirely unregulated, to being brieflymanaged, to being completely prohibited. Out of the 11 more common species, five showed no change in relative abundance over time, two (Centrophorus squamosus and Centroselachus crepidater) declined significantly and four increased in relative abundance (Apristurus aphyodes, Apristurus microps, Galeus melastomus and Deania calcea).
