Introduction

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

Cruise Inventory Information

Long name FRV Scotia (748S) cruise 1406S
Short name 1406S
Objectives and Narrative FRS Objectives

1. Routine daylight survey of the Rockall Plateau to assess the haddock stock within the 200 metre contour.
2. Nephrops TV observation work along the East edge of the bank to depths of 500 metres.
3. Identify, quantify and record all benthic invertebrate species caught.
4. Obtain temperature and salinity data from the surface and seabed at each trawling station.
5. Collect additional biological data in connection with the EU Data Directive 1639/2001.

PU / JNCC Objectives

1. Opportunistic use of the drop frame and to contribute to mapping distribution of Annex I reef habitat as required under the EC Habitats Directive.
2. Collection of invertebrate fauna from trawl samples.

Aberdeen and Bristol University Objectives

1. Carry out behavioural experiments on bioluminescent organisms retrieved using deep-water free-fall traps (maximum of 3 deployments).
2. Collect fish eyes from a range of depths (<200m to 1800m) for visual pigment studies; spectroscopy and molecular studies of pressure sensitivity of enzymes.

Narrative

Scotia sailed from Aberdeen at 1530 on Friday 8 Sept and proceeded to make passage to the first fish trap deployment at position 57.36N 12.52W. Scotia arrived on station at 0410 10 Sept and the trap was successfully deployed at a depth of 1039metres. Scotia continued west to position 57.31N 13.25W where fishing commenced at 0700. Trawling continued during daylight hours for the next 6 days, with a 5 hour interruption for weather on the morning of the 14 Sept. In line with the WTD 6-7 hauls were completed within the 13 hour working day. On the afternoon of 15 Sept the net was badly damaged by a boulder and with an increasing forecast the decision was taken to drop the last 3 hauls of the haddock survey. Prior to the weather deteriorating the 2000kg trawl doors were dropped into position in readiness for deepwater fishing. During trawling downtime the Drop Frame was deployed at various locations to assess Nephrops abundance and map distribution of Annex I reef habitat at selected sites.
