Summary: | Seasonal variation in lipid reserves of Calanus finmarchicus between seven different sampling zones namely; Central, North and Southern Irminger Sea, East Greenland Sea with characteristic current of Atlantic and Polar origin, Iceland Shelf, and Raykjanes Ridge (RR) were determined using High Performance Liquid Chromatography equipped with an Evaporative Light Scattering Detector (HPLC-ELSD). Wax ester (WE) and Triglycerides (TG) were the main lipids classes in C. finmarchicus. Along sampling zones in both spring and summer, the highest concentration of total storage lipids (WE+TG) were in samples from Central Irminger Sea (CIS) and the lowest in samples from Southern Irminger Sea (SIS). WE, TG as well as, the total storage lipids were significantly different between sampling zones and seasons, with WE in spring being lower than those in summer, and TG being higher in spring than in summer. Thus storage lipids varied along sampling zones between seasons in the Irminger Sea
