Specialists from the Rosneft Arctic Research Center, together with scientists from the country's leading research institutes, have summed up the results of the polar bear field season as part of the Tamura corporate biodiversity conservation program. Three expeditions were conducted in the spring to study the Arctic predator population.
Representatives of the Company, the Ministry of Natural Resources and Environment of the Russian Federation, the A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences, as well as specialists from the Biotechnology Campus (BTC) Center for Whole-Genome Sequencing, spoke about scientific work in the north of Krasnoyarsk Krai at a press breakfast.
In 2025, scientists were faced with the task of conducting the first full-scale aerial survey of the Kara subpopulation of polar bears in Russian practice. Specialists made 25 flights, the total length of air routes was almost 24 thousand km. During the expeditions, about 170 thousand photographs were taken, as well as 540 thousand infrared photographs, which will be processed using artificial intelligence.
According to the expedition participants, 8 flights of the laboratory aircraft were made from the village of Sabetta in Yamal for a comprehensive survey of the inner delta of the Gulf of Ob and the southeastern part of the Kara Sea. During the aerial visual observations, 22 polar bears, 23 walruses, 616 seals, 77 belugas, and rare bird species were recorded.
Ten helicopter flights were made from the village of Dikson to survey the ice of a number of islands, as well as the ice in the Yenisei Gulf to Sever Bay and along the northern coast of the Taimyr Peninsula to the mouth of the Uboynaya River. During the work, 37 polar bears of various ages and both sexes were registered. 10 animals were tagged with satellite collars and ear tags for remote tracking of migration routes. Scientists also took samples of the polar bears' fur and blood to study their health and genetic affiliation to a particular subpopulation – the samples are already being studied by BTK specialists. The location of two abandoned polar bear maternity dens and the habitat of the bears' main food source – the ringed seal – were also determined.
Also from the village of Dikson, scientists surveyed the central and south-eastern waters of the Kara Sea. Specialists carried out 7 flights and registered 12 polar bears, 16 belugas and 420 seals. Specialists noted that based on the results of the work, the number and distribution density of polar bears and their food sources in the Kara Sea will be determined.
Rosneft pays special attention to environmental issues and biodiversity conservation and is implementing the largest comprehensive Arctic region study program since Soviet times. The goal of the new Tamura research program, which started in 2024, is to update information on the state of key animal species in the northern region. The Tamura program includes studying the Kara subpopulation of polar bears, wild reindeer populations in western Taimyr, and valuable bird and fish species in the Yenisei estuary. The data obtained will allow scientists to draw conclusions about the state of ecosystems and develop measures to preserve the region's biodiversity. In 2024, scientists conducted five expeditions, and ten expeditions will be held in total over four years.
