Abstract:
The article presents environmental risk assessments for Arctic shelf ecosystems based on a probabilistic model. Calculations were carried out using observations of seasonal variations of phytoplankton biomass in the Arctic seas. To calculate the environmental risk according to the probabilistic model, the authors used data on the probabilities of impact on marine ecosystems from stressors, taking into account the risks from technological processes of offshore resource development. The results made it possible to calculate the probabilities of acceptable impacts on highly productive and low-productive ecosystems of the Arctic shelf. Comparison of risk modeling results showed that due to the low productivity of marine ecosystems, reliability requirements for technological processes that ensure the safety of Arctic resource development should not be reduced.
