2012 University of Plymouth Jersey Epifauna survey towed underwater video Epifauna survey

Abstract

This dataset comprises marine epibenthos (approx. 26 identified taxa derived of Algae, Annelida, Arthropoda, Bryozoa, Chordata, Cnidaria, Echinodermata, Mollusca, Nemertea, Porifera) and associated habitat data (percentage cover maerl, sand, reef and shell) collected during August 2012 as part of an investigation to identify and map maerl beds off the east coast of Jersey, Channel Islands, UK. 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.

If any sensitive species or biotope records are present within this dataset, they will have been removed. If you wish to request access to sensitive species records, please contact the metadata contact. The UK Sensitive Species list has been agreed by UK statutory bodies and relevant experts. It can be viewed here https://docs.nbnatlas.org/sensitive-species-list/. Please note sensitive species lists can vary across the UK. Based on the dataset: E.V. Sheehan, D. Bridger, M.J. Attrill 2015.

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.
