Wax ester composition of the dominant calanoid copepods of the Greenland Sea/Fram Strait region
The composition of the intact wax esters of Calanus hyperboreus, C. finmarchicus, and C. glacial is from the Fram Strait area of the Greenland Sea was studied. In addition the fatty acid and alcohol composition of the wax esters was analysed. All copepods were rich in wax esters, especially C. hyper...
