Vulnerability coefficients of marine mammals to oil were calculated for the Kola Bay based on the potential impacts, sensitivity and recoverability. For the sensitivity, a film thickness of 5 mm was assumed, at which negative effects from the inhalation of hydrocarbons can appear, and 0.1 mm as inactive film thickness on the marine mammals. The values of probability impact of oil on pinnipeds –1 % and cetaceans –0.1 % were adopted according to the time which animal spend diving and during the surface. Given the number of marine mammals in the Barents Sea and the Kola Bay, the recovery time for marine mammals in bay is accepted as 1 year.
