Title

2011 Scottish Natural Heritage (SNH) biological analysis of Marine Scotland (MS) Orkney benthic survey

Abstract

The purpose of this MPA assessment benthic survey in Orkney waters (Rousay to Copinsay, including Eday Sound, and points in Scapa Flow) was to improve knowledge of the occurrence and distribution of species and habitats of recognised conservation importance, particularly priority marine features (PMFs). This survey is part of the SNH and MS MPA assesment of Scotland 2011. Underwater video tows and day grab sampling were conducted by Heriot-Watt University for MS from the 1st to 11th September 2011 to collect detailed biological information on the seabed species and habitat features present and aid biotope assignments to each station. Diver MNCR surveys were conducted at sites where healthy Modiolus modiolus and Mearl beds were observed on video, and diver core samples taken to investigate infauna and PSA. Analyses of the seabed video and still photographic imagery were used to describe the nature of the seabed in terms of the physical structure and the species assemblages.

Lineage

Data collected by scientists from SNH, HWU and MSS. Standard survey methods were used to deploy a drop down video sledge to record footage from predetermined random points within the survey area, day grab samples with PSA subsamples were also taken at random sites to aid in biotope assignment to each station. Grab samples were processed on board over a 1mm sieve then analysed fully on return to the lab by external contractors for infauna and PSA. Diver MNCR surveys were carried out at healthy MPA search features stations, and core samples taken for infauna, epifauna and PSA analysis. Species data collected from DDV analysis and infaunal analysis were run through Primer V6, to asses any differences between stations. Biotopes were assigned to stations using Connor et al V 04.05.
