OREANDA-NEWS Specialists from Rosneft's Arctic Research Center, together with scientists from Russia's leading scientific institutes, summed up the results of the polar bear research field season as part of the Tamura corporate biodiversity conservation program. In the spring of 2025, three expeditions were organized to study the Arctic predator population.
At the press breakfast, representatives of the company, the Ministry of Natural Resources and Ecology of Russia, the Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences, as well as specialists from the Biotechnological Campus Center for Genome-wide Sequencing spoke about the progress and results of field work.
The main task of the current season was to conduct the first full-scale aviation accounting of the Kara polar bear subpopulation in Russian practice. In total, the specialists completed 25 sorties, the total length of the routes was almost 24 thousand kilometers. During the work, about 170,000 photographs and more than 540,000 infrared images were taken, which will be processed using artificial intelligence technologies.
Eight laboratory aircraft sorties were carried out from the village of Sabetta in Yamal, during which the inner delta of the Gulf of Ob and the southeastern part of the Kara Sea were examined. According to the results of aerial visual observations, 22 polar bears, 23 walruses, 616 seals, 77 belugas, as well as rare bird species were recorded.
10 helicopter sorties were carried out from the village of Dixon, the purpose of which was to survey the ice of the islands, the ice zone of the Yenisei Bay to the North Bay, as well as the coast of the Taimyr Peninsula to the mouth of the Uboynaya River. As a result, 37 polar bears of both sexes and of different ages were recorded. Ten animals were fitted with satellite collars and ear tags for remote migration monitoring. The specialists also took wool and blood samples to assess the health of the animals and establish their genetic affiliation. The biomaterial is currently being studied at the Biotechnology Campus Center. As part of the work, the location of two abandoned ancestral dens was also determined and the habitats of the main food item of polar bears, the ringed seal, were recorded.
During the third expedition, which also started from the village of Dikson, scientists surveyed the central and southeastern waters of the Kara Sea. During the 7 sorties, 12 polar bears, 16 belugas and 420 seals were recorded. Based on the results of all the expeditions, the number and distribution density of polar bears and their food supply in the Kara Sea will be determined.
Rosneft is implementing the largest comprehensive Arctic exploration program since the Soviet era. The Tamura program, launched in 2024, aims to update data on the status of key species of northern animals. It studies the Kara polar bear subpopulation, wild reindeer populations in western Taimyr, and valuable fish and bird species in the Yenisei estuary. The data obtained will allow scientists to form a scientific basis for assessing the state of ecosystems and developing measures to preserve biodiversity. In 2024, five expeditions were conducted within the framework of the program, and ten are planned to be organized in just four years.
