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.

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.
