The expedition of the Institute of Oceanology of the Russian Academy of Sciences boarded the “Mstislav Keldysh” ship to the Kara Sea to study the impact of climate change on the state of Arctic ice.

The university's press service said that oceanologists will receive new results for predicting changes in marine Arctic natural complexes under the influence of climatic trends and increasing anthropogenic load.

Along the entire route of the expedition, scientists led by academician Mikhail Flint will measure hydrophysical, hydro-optical and biophysical parameters in the surface layer of the sea, as well as collect samples using 60 oceanological and 30 hydrophysical, biological, geological and geochemical stations.

The expedition will last 43 days.

This is the 14th expedition under the program "Ecosystems of the seas of the Siberian Arctic". Research in the Kara, East Siberian Seas and the Laptev Sea provides a basis for understanding changes in Arctic processes under the influence of natural and anthropogenic factors, ttelegraf.ru reports.
