In recent years the temperatures measured in the Barents Sea have raised. Temperatures were at their peak in 2007.
Increasing petrolium and gas exploration may affect marine organisms like capelin eggs.
During the 2009 capelin winter survey 4600 eggs were sampled and brought to IMR for further examinations.
Malformations and mortality in embryos and larvaes were studied. The main goal of the project is to find out how temperature and contaminants affect the capelin at these vulnerable life cycle stages.
