|Ship name (ship code)||FRV Scotia (748S)|
|Cruise period||2014-10-28 — 2014-11-10|
|Port of departure||Aberdeen, United Kingdom|
|Port of return||Aberdeen, United Kingdom|
1. To gather high resolution video and still images along transects and from quadrats throughout Solan Bank using a TV drop frame system.
2. To gather environmental data using a CTD (salinity, temperature, depth, fluorescence and turbidity) from the same area.
3. To gather high resolution underwater video and stills data to update existing substrate maps of the site
4. To log ADCP data (current speed and direction) from throughout the area of interest.
All staff will join Scotia either on the afternoon or evening of 27 October, so allowing the vessel to depart Aberdeen Harbour as early as possible on 28 October. After completion of safety drills and exercises, Scotia will proceed northwards to the vicinity of the Southern Trench where gear testing will be undertaken. The vessel will then make passage to Solan Bank and commence sampling on the targeted sampling station grid and on the stratified random sampling stations. The TV drop-frame with attached CTD will be deployed at each station allowing simultaneous logging of imagery and environmental data (temperature, salinity, fluorometry and turbidity). Surface salinity samples will also be collected from the water sampling lab as required.
In the event of downtime because of weather or completion of the two primary objectives, further sampling will be carried out on the habitat mapping stations. ADCP data may be also be collected, the actual latitude and longitude data for these stations will be provided while at sea. Depending on the severity of weather conditions and wind direction, further contingency sampling for SNH may be carried out.
A full and detailed survey plan will be provided at the pre-brief meeting, before the beginning of the survey. The thermosalinograph will be run throughout the survey.
