Abstract

Marine Scotland Science (MSS) collect Nephrops underwater television (UWTV) footage annually. Data from 2019 and 2020, collected inside and adjacent to Central Fladen Marine Protected Area (MPA) by MRV Scotia (ICES 2020), was made available to JNCC.

Approximately four and a half hours of footage from 27 video stations was analysed in BIIGLE to identify transects where the Burrowed mud (Sea pens and burrowing megafauna and tall sea pen components) Priority Marine Feature (PMF) was present. Video imagery was analysed to assign broadscale habitats and biotopes from the ‘Marine habitat classification of Britain and Ireland’ version 15.3 (MNCR), identify conspicuous taxa, record evidence of human impacts, calculate the density of burrows and sea pens at each station, and evaluate the extent to which the analysis results could be used to assess the Burrowed mud and Sea pen and Burrowing Megafauna Communities features.
