2012 University of Plymouth Falmouth towed underwater video maerl and associated epifauna survey
This data set comprises of marine epibenthos and endobenthos (approx. 370 identified taxa derived from Algae, Annelida, Arthropoda, Bryozoa, Chordata, Echinodermata, Hemichordata, Mollusca, Nematoda, Nemertea, Phoronida, Porifera and Sipuncula), associated with maerl beds in Falmouth Harbour, UK quantified between 2011 â 2013 using a towed underwater video system and hand cores taken by SCUBA divers. Additional data on sediment (organic content and particle size) and the porosity of maerl found at the sites are also provided. Surveys were conducted to assess the extent, distribution and species composition of maerl bed habitats within the harbour in response to proposed dredging activities to deepen the shipping channel. To establish the location and extent of maerl beds and quantify the abundance of epifauna transects were undertaken using a high definition towed underwater video system. Towed video surveys took place in November 2011 and February 2012 and transects were approximately 200 x 0.5 metres. Core samples collected by divers September - November 2012 and July - August 2013 were used to further assess habitat quality and species distribution by quantifying the abundance of infauna and analysing organic content, particle size and maerl structure.

Dataset Citation: Dr Emma V Sheehan; University of Plymouth School of Marine and Biological Sciences, UK (2015) Species composition and sediment properties of maerl bed habitats in Falmouth Harbour, UK using towed underwater video and diver cores. 10.17031/8a7e-s138. 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 dataset: Sheehan EV, Bridger D, Cousens SL, Attrill MJ (2015) Resilience of dead maerl infaunal assemblages to experimental habitat removal and replacement. Marine Ecology Progress Series 535:117-128. doi:10.3354/meps11400 This is part of the series set '2011-2013 University of Plymouth Falmouth towed underwater video maerl and associated epifauna survey' DASSHSE00000058. Sheehan EV, Bridger D, Attrill MJ (2015) The ecosystem service value of living versus dead biogenic reef. Estuarine Coastal and Shelf Science 154: 248-254. doi:10.1016/j.ecss.2014.12.042 Surveys conducted by the University of Plymouth. Towed underwater video system deployed from a small vessel 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.
