Abstract
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 to 3.39 mm in summer C6). Prosome lengths varied with stages and season showing small C4 stages with mean prosome lengths of 1.8 mm to larger female C6 with mean prosome lengths measuring up to 2.8 mm. © 2008 Asian Network for Scientific Information.
