Introduction

This report collates information from the BODC cruise inventory and oceanographic databases. It presents

Cruise Inventory Information

Long name FRV Scotia (748S) cruise 1011S_1
Short name 1011S_1
Objectives and Narrative Objectives

1. To undertake the bottom trawl survey of haddock on the Rockall Plateau to depths of 400 m.
2. To deploy a CTD at each trawl station to collect temperature and salinity profiles.
3. To collect samples (genetics and otoliths) for key species for population studies, contaminant studies and other requests, e.g. MSFD litter recording.
4. To map seabed habitats and coral reefs using towed VMUX chariot video system and/or the swathe multibeam echosounder.

Procedures

The primary objective of this part of the survey is to assess the state of the haddock stock on the Rockall Plateau. Although the Rockall haddock survey has existed for a number of years a new sampling design is currently being developed. Trawling will be carried out during the hours of daylight at randomly selected locations within the 400 metre contour. The exact locations of the trawling stations will be notified to the vessel at the commencement of the cruise. One haul of 30 minutes duration will be made at each sampling station; trawling operations will occur in waters to a maximum depth of 400m. Daily start times for survey stations will be at approximately 0600h and continue until approximately 2000h. The Scanmar system will be used to monitor wing spread, door spread and distance covered during each haul. A bottom contact sensor will be mounted on the footrope to record the distance of the trawl off the seabed. Catches will be worked up according to the protocols for International Bottom Trawl Surveys and in line with MSS Standing Instructions. A CTD will be deployed at each trawl station.

At night the VMUX towed video chariot will be deployed in and outside areas closed for the protection of coldwater coral reefs and in areas of interest identified within the 12 mile limit of the islet of Rockall. In the case of weather conditions curtailing deployment of the VMUX, the swathe MBES will be considered as an option for opportunistic mapping of the seabed building on previous swathe mapping of the area. Upon completion of the Rockall haddock survey, passage will be made to Ullapool for half-landing on or around 3 September. The GOV net and associated gear will be stripped down and offloaded together with TV kit at Ullapool in exchange for the deepwater trawl gear.
