ObjectivesObjectives

1. Complete an internationally coordinated demersal trawling survey in the North Sea in ICES area IV.
2. Obtain temperature and salinity data from the surface and seabed at each trawling station using a SEABIRD 19+ CTD.
3. Install, test and proceed with using newly purchased EDC (electronic data capture) and FSS database for recording of all biological survey data.
4. Collect additional biological data in connection with the EU Data Collection Framework (DCF).

Procedures

Loading of the trawl gear will take place on 29 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 Wednesday 31 July. The first station is located not far from Aberdeen, so once the 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 the 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.

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, wing spread 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.

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 and will provide information on salinities, nitrates, silicates and phosphates. In addition, the ships thermosalinograph will be run continuously throughout the survey and will provide sea surface temperature and salinity data.

Installation of new Data Recording System (FSS and EDC)

Additional personnel have been drafted in to aid in this process and this task will have zero impact on the survey programme as such and will take place whilst the day to day running of the survey proceeds. The timetable is to have this system fully tested, installed and working by the mid-survey break.
