BODC Cruise Metadata Report for FRV Scotia (748S) cruise 0911S

Introduction

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

Cruise Inventory Information

Long name FRV Scotia (748S) cruise 0911S
Short name 0911S
Objectives and Narrative Objectives

1. To complete an internationally coordinated demersal trawling survey in the North Sea in ICES area IV...
2. To obtain temperature and salinity data from the surface and seabed at each trawling station.
3. Collect additional biological data in connection with the EU Data Collection Framework (DCF).
4. Opportunistic Benthic sampling in collaboration with JNCC utilising both the drop frame for observational work and the Day Grab for sediment verification.

Procedures

General

Loading of the trawl gear will take place on 26 July with rigging and testing being completed on the same day. Loading of the scientific gear will also take place on the same day. Scotia will then sail on the morning of 29 July. The first trawl station is close to Aberdeen therefore once safety drills have been completed Scotia will proceed to the first station where a shakedown haul will be completed in advance of the first real haul in order to check the net configuration and Scanmar units. An operational daily survey plan will be formulated by the SIC subsequent to meetings with both the Fishing Master and the Captain. It is the intention that these meetings take place where possible during times that are mutually convenient. Similar discussions will take place when organising the benthic work at night and will include the scientist leading the benthic operations.

Trawling

One demersal haul of 30 minutes duration will be made in each statistical rectangle shown on the attached chart. Trawling will be undertaken during the hours of daylight, which will vary depending on the vessels latitude at any given time. The Scanmar system will be used to monitor the headline height, wingspread and door spread for each haul. Bottom contact data from each trawl will also be collected using the NOAA bottom contact sensor, which will be mounted in the centre of the ground-gear. In addition to the routine sampling, biological data will be collected for target species in line with the EU data regulation. All fish will be processed in accordance with Standing Instructions.

Hydrography

CTD casts will be taken at every trawl station. These provide surface and bottom temperature and salinity information. Reverser bottles affixed to the CTD wire will also be used to collect water samples that will be analysed back at the lab. This will provide information on salinity, nitrates, silicates and phosphates at each station. In addition, the ships thermosalinograph will be run continuously throughout the cruise and will provide sea surface temperature and salinity data.

Benthic Work

This work is a collaboration between MSS and JNCC and will be undertaken within UK waters during the hours of darkness once trawling operations have ceased for the day. The work will involve deployment of the drop frame from the aft deck and recording TV and photographic stills footage of the seabed via an umbilical cable. In addition, the Day Grab will also be deployed from the hangar deck and this will provide highly resolved information on faunal structure as well as substrate type.
