Introduction

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

Cruise Inventory Information

Long name FRV Scotia (748S) cruise 0311S
Short name 0311S
Objectives and Narrative Objectives

1. Demersal trawling survey of the grounds off the north and west of Scotland in ICES Subarea VIa.
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. Collect abundance data on herring larvae using the Methot net.

Procedures

General

Loading of the trawl gear will take place on 17 February with rigging and testing being completed on the same day. Loading of the scientific gear will take place on 18 February. Scotia will then sail on the morning of Tuesday 22 February. A training haul will be undertaken during the passage north to ensure all fishing gear/sensors are working effectively. Scotia will then proceed north and commence fishing operations the next morning on predefined stations off the north Scottish coast and west of 4'W with weather conditions thereafter determining the route taken on the survey.

Trawling

This year the survey design, rather than relying on fixed trawling locations will move to a new random-stratified survey design with trawl locations randomly distributed within 6 predefined sampling strata. The random positions have still to be generated and once this takes place they will be circulated to the vessel in advance of the survey for the fishing master to examine. The intention is for trawls to be undertaken on suitable ground as near to the specified sampling position as is practicable and where possible within a radius of 5 nautical miles of the sampling position. Hauls will be of 30 minutes duration and, in the main, fishing operations will be restricted to daylight hours between 0700 and 1800 though exact start and finish times will vary slightly according to geographical location. 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 on a bar 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 each trawl station; in addition, the thermosalinograph will run continuously to obtain sea surface temperature and salinity throughout the survey area.

Methot Net Sampling

Oblique tows will be carried out in all ICES statistical squares where the trawl is deployed. It is the objective to complete 2 methot samples in each square. These will be undertaken during the hours of darkness using the Methot mid-water trawl (round frame).
