Seasonal Variation In The Physical Characteristics Of The Copepod Calanus Finmarchicus (Gunnerus) Along The North Atlantic, A. A. Yusuf, L. Webster

All Peer-Reviewed Publications

Physical oceanographic changes such as the North Atlantic Oscillation, which manifested in the 1990s, are said to affect the seasonal/stage dependent, vertical migrations and life cycle of Calanus finmarchicus. C4-C6 stages of C. finmarchicus collected during spring and summer in 2002 from the Irminger Sea, Greenland Sea, Iceland shelf and the Raykjanes Ridge were analysed microscopically for their prosome and total body lengths and gravimetrically for dry weights. Dry weight ranged from 60 μg individual-1 in C4 to 326.6 μg individual-1 in C6 stages. Total body lengths showed an increase with sample stage and season (2.10 mm in spring C4 …
