Jersey’s coastline plays host to a rich variety of marine life, the waters around the island were previously thought to host maerl beds although the location and extent of this ecologically important habitat was unknown. 47 transects were undertaken using a towed high definition video camera, each transect being approximately 200 x 0.5 metres. As a result of this work the maerl beds identified in south east Jersey were subsequently protected from destructive bottom towed fishing activity.

In house standard operating procedures (SOPs) were followed. See Sheehan et al. 2010 and Stevens et al. 2014 https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0014461 http://dx.doi.org/10.1016/j.marpol.2013.09.006. In house QC scheme followed. A sub-set of the analysed still frames from the video data was checked (reanalysed and compared to original analysis) by a senior video analyst. Further quality analysis carried out by a DASSH data officer.
