Metadata: 2011 University of Plymouth Falmouth towed underwater video maerl and associated epifauna survey
Abstract:
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 in 2011 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.

| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | 2011 University of Plymouth Falmouth towed underwater video maerl and associated epifauna survey |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | 1a263429344bd29d4d2e0d991788f572 |
| Resource Identifier | This is the code assigned by the data owner. | DASSHDT00000461 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2011-11-22 |

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. |
