Objectives | 1. To investigate the structure of plankton patches associated with the
oceanic front the west central North Sea.
2. To investigate the vertical distribution of planktonic organisms,
particularly fish larvae in (a) mixed water and (b) stratified
water.
3. To investigate physical and chemical features of the water masses in the frontal zone.
4. To collect berried crabs (Cancer pagurus) for laboratory studies on the development of larvae.
5. To tag surplus and immature crabs and release in the area of capture. |
