ObjectivesTo study the aspects of overwintering strategies of neritic copepods.
(1) To determine the abundance, identity and viability of calanoid copepod eggs in representative sea bed sediments under a range of depths of water. The sediment samples will also be used for the study of dinoflagellate cysts.
(2) To identify aggregations of planktonic calanoid copepods on the sea bed (to feed on sedimented detritus) when suspended food in the water column is scarce and to determine the structure of the populations of calanoid copepods.
(3) To assess the comparative importance of lipid reserves in calanoids, particularly Pseudocalanus elongatus and Acartia clausi.
