The large scale and long-term research sea expedition along Kamchatka and Chukotka coasts “The Uykoal Land” has been successfully completed! The participants of the expedition sailed about 2500 nautical miles on the severe Bering Sea and approximately 700 km down the Kamchatka River. The expedition program has been totally fulfilled. We gathered an extensive data on distribution and numerosity of marine mammals, some birds species; on rare plants of the region. The Research Centre has supplied its scientific collections with new interesting exhibits. The extreme part of the expedition was especially remarkable for unplanned visits of brown bears during stops.
