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

Cruise Inventory Information

Long name FRV Clupea (74CU) cruise 0498C
Short name 0498C
Objectives and Narrative 1. To determine the abundance and distribution of piscivorous demersal fish species by bottom trawl survey.
2. To determine the age and length composition, and age-length and weight-length relationships, of piscivorous demersal fish species. Stomach samples will be collected to determine the diets of these fish predators.
3. To assess the abundance of sandeels in the sediment by grab sampling survey (approximately 300 grab stations). Sandeels caught will be measured and weighed and otoliths taken for age determination. Sediment samples will be taken to investigate the relationship between sandeel density and sediment particle size distribution, and to improve the ground-truthing of the RoxAnn data.
4. To compare the effectiveness of grab sampling (a further 200 grab stations approximately) and dredging (being done by RV Bernicia) as a means of estimating sandeel density in the sediments. Sandeels caught will be measured and weighed and otoliths taken for age determination.
5. To determine the abundance and distribution of clupeids and sandeels in the water column off the Firth of Forth by echo-integrator survey.
6. To determine sandeel and clupeid age and length composition by pelagic trawl sampling. Weight-length and age-length relationships will be determined. Otoliths will be collected for age determination.
7. To map seabed sediment type using ROXANN, backed up by grab sampling.
8. To determine spatial variation in the temperature and salinity profiles in the water column using a Seabird CTD sampler.
9. To determine the abundance and distribution of other top predators (seals, cetaceans, seabirds) in relation to pelagic fish distribution.
