PurposeResearch
ObjectivesAims:

1. To use a 2m beam trawl to collect representative samples of benthic organisms on the sandeel fishing grounds on the North West Riff & The Hills.
2. To use fishing survey methods to estimate the abundance and distribution of predatory fish feeding on sandeels and benthos at the same stations.
3. To use fishing survey methods to estimate the habitat occupancy of sandeels on the same grounds.
4. To process multibeam data recorded on the minigrids.

Narrative:

The scientific crew joined the Endeavour at Lowestoft at 10:30hrs on Wednesday, 27th September. Endeavour then steamed to The Hills (~54 25 N, 01 00 E). Surveying for sandeels and their predators commenced at 21:00hrs that evening. Surveying took place over established grids on the Hills and the North West Riff. Each day a 2m beam was trawled to sample benthos on 4 pre-selected stations and at the same 4 stations a granton was used to trawl for predators. During the first two days the beam was trawled in the morning (07:00~12:00) and the granton in the afternoon (13:00~17:30).
The rest of the trip granton was shot in the morning (07:00~12:00) and the beam in the afternoon (13:00~17:00). During the morning shift (06:45hrs~11:00hrs) the vessel steamed across all 6 stations of two transects to record fisheries acoustics data. Dredging for sandeels began at 21:00hrs, and was usually completed between 02:00 and 03:00hrs. The shift pattern operated continuously for the first 10 days of the cruise. Surveying was completed on 8th October at 11:00hrs, whereupon Endeavour set a course for Lowestoft, arriving inshore on the evening of the 8th. Due to strong southerly winds, however, Endeavour could not dock until 10:00hrs on the 9th.
