Title

2010 University of Plymouth Guernsey towed underwater video benthic survey

Abstract

This data set comprises of marine epibenthos (approx. 74 identified taxa derived from Algae, Annelida, Arthropoda, Bryozoa, Chordata, Cnidaria, Echinodermata, Mollusca, Porifera) data collected during September 2010 from the Big Russel channel in Guernsey, Channel Islands, UK. Surveys were appointed as part of a Regional Environmental Assessment to determine the feasibility of marine renewable energy developments in the area. Data were collected using a high definition towed underwater video system. 36 transects each approximately 200 x 0.5 metres were undertaken to document the epibenthos in the Big Russel, providing a baseline of species composition in an area where tidal development may occur and to identifying suitable control areas for future impact assessments.

Dataset Citation: Dr Emma V Sheehan; University of Plymouth School of Marine and Biological Sciences, UK (2013) Epibenthos and subtidal reef habitats of Guernsey, UK using towed underwater video. 10.17031/qma0-wb23. 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: Emma V. Sheehan, Sarah C. Gall, Sophie L. Cousens, and Martin J. Attrill (2013) The Scientific World Journal, Epibenthic Assessment of a Renewable Tidal Energy Site. University of Plymouth School of Marine and Biological Sciences. http://dx.doi.org/10.1155/2013/906180. Towed underwater video system deployed from a small fishing trawler and towed behind attached to an umbilical, recording real time video observed on a topside computer monitor screen and stored on the computer's internal hard drive for later back up. 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.
