Sea pen density data in towed video from Farne Deeps 2016 dataset https://portal.medin.org.uk/portal/start.php?tpc=009_CEFASa66db34e-d3f3-4ce2-8b78-c7d0084bd519 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. 20231101 20221013
