Title

2016 Scottish Natural Heritage (SNH) Sound of Mull benthic camera survey

Abstract

The primary aims of this benthic survey in the Sound of Mull, a region within the Loch Sunart and Sound of Jura MPA, were to monitor MPA management effectiveness and for contingency sampling to improve knowledge of the occurrence of species and habitats of recognized conservation importance. The survey was run by SNH and Marine Scotland Science (MSS) for SNH on the 18th April 2016 using MSS vessel MRV Alba na Mara (cruise 0616A). Drop-down camera sampling undertaken at 8 stations was used to collect this quantitative data. Through the analysis of seabed video, the images were used to describe the nature of the seabed in terms of the physical structure and the species assemblages. Runs and run segments were assessed for the presence of protected features and other PMFs, as well as for the presence of species and habitats of recognised conservation importance.

Lineage

This subtidal seabed data from the Sound of Mull was collected during a research cruise run by SNH on board the MSS vessel MRV Alba na Mara (cruise 0616A) on the 18th April 2016. A total of 8 stations were sampled using drop-down video camera. Images were obtained using a 1cam alpha Mk5 video camera, set for RS485 and fitted with 256GB of onboard memory, and a Kongsberg OE14-408 underwater digital stills camera. The video frame carried a Savante LMNI-subsea laser scaling system with green lasers set to 45cm apart and red laser dots 64mm apart. Digital still photographs were taken approximately every 30 seconds with the camera frame landed. A high definition (HD) video camera was deployed in combination with a lower resolution (720x576) navigation camera. HD video footage was recorded at a resolution of 1920x1080. Track position, time, date and depth data were displayed on a SD video overlay system. Analyses of the video footage was undertaken by SNH contractor Dr Colin Moore to describe the physical structure and species assemblages present. Species present were identified and quantified using the semi-quantitative MNCR SACFOR scale, as far as possible. Biotopes were allocated based on the biological and physical attributes. Where the video run traversed a sequence of biotopes, the run is split into corresponding segments with the transition points recorded using the time, position and depth.
