2015 Scottish Natural Heritage (SNH) South Arran benthic camera and grab surveys

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. The surveys were undertaken in two stages; in July and September 2015. 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. 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. The aim of this benthic survey in South Arran, run by SNH for SNH from the 17th-21st September 2015 onboard the Marine Scotland Science vessel MRV Alba na Mara (cruise 1415A), was to assess the condition of seabed habitats within the South Arran ncMPA. 54 grab samples were collected at 5 stations during this survey period (17-20th). Faunal identification and sediment particle size analysis (PSA) of the grab samples was undertaken and biotopes assigned to each sample by Seastar Survey Ltd, contracted by SNH. Dropdown video drifts at 24 stations were also undertaken on this survey (17-21st). Reporting of the results from the video survey in South Arran has not yet been completed.
