PurposeResearch
Objectives1. To investigate variation of sandeel population age structure at different locations on the Wee Bankie and Marr Bank from samples collected using the sandeel dredge.
2. To determine spatial variation in seawater temperature/salinity and chlorophyll across the study area using a Seabird CTD sampler.
3. To investigate potential new sites for sandeel dredging, using the sandeel dredge and day grab in the Firth of Forth.
