Ziel der Reise / Objectives of Cruise:

1. Development of methodology for sandeel surveys, including in situ measurements of acoustic target strength and survey design. 2. Estimation of sandeel abundance in the North Sea using echo sounder, drege and van Veen grab. 3. Studies of diet in sandeel in relation to food availability in the planktonic community.
