2015 Scottish Natural Heritage (SNH) South Arran benthic camera and grab survey (July)
Benthic habitat survey of protected seabed habitats undertaken within the South Arran MPA between the 14th - 20th July 2015 by SNH for SNH on board the vessel MRV Seol Mara. The primary aim of the grab survey was to establish current baseline conditions for a range of features present within the site, against which future change can be determined. 36 grab samples were collected at 4 sites within the South Arran MPA during this survey period (15-19th). Faunal identification and sediment particle size analysis (PSA) of the grab samples was undertaken and biotopes assigned to each sample by Precision Marine Survey Ltd, contracted by SNH. Reporting of the results from the video survey in South Arran has not yet been completed.

This subtidal seabed data was collected during a research cruise by SNH on board the vessel MRV Seol Mara. Thirty six grab samples were collected in total within the MPA. At each station a single grab sample was collected using a 0.1m2 Day grab. Sampling locations were selected within 4 depth and habitat stratified sampling boxes. For each grab sample, a subsample was removed for separate particle size analysis (PSA) and stored in a plastic bag before being frozen. The remainder of the infaunal sample was passed through a 1mm mesh sieve, and the residue retained and fixed using a borax buffered formalin. Laboratory methodologies were undertaken in line with NMBAQC Scheme guidelines. Identification of infaunal samples was to the lowest possible taxonomic level (e.g. species). The sediment type derived from PSA and the characteristic species identified from each sample were used to characterize the biotope for each grab station, according to the Marine Biotope Classification of Britain and Ireland. Precision Marine Survey Ltd. were contracted by SNH to undertake faunal analysis and PSA of the samples from this survey.
