The dataset contains count and density (ind./m2) of the sea pens
Pennatula phosphorea and Virgularia mirabilis in 121 video transects
collected using a towed camera sledge at Farne Deeps (ICES Functional Unit 6)
in June 2016. The data is saved as a csv file containing the video recording
identifier, station identifier, video tow start and end coordinates and count
and density of each sea pen species. The sea pen counts were extracted for the
purpose of mapping sea pen density across the Farne Deeps mud basin. The video
footage was originally collected as part of a programme of stock assessments
for the Norway lobster (Nephrops norvegicus) coordinated by the the ICES
Working Group on Nephrops Surveys (WGNEPS). The video surveys are carried
out annually for specified Nephrops fishing grounds (‘Functional Units’,
FU) for use by the European Commission to set annual Total Allowable Catches
(TAC’s) at the ICES sub-area level.
