The Great Scientific Expedition of Norilsk Nickel and RAS used UAVs and AI to collect data

20 february 2024

Participants of the Great Scientific Expedition of Norilsk Nickel and the Siberian Branch of the Russian Academy of Sciences (RAS) used latest technologies to collect and quickly analyze research data, said Olga Krever, Deputy Director of the Federal State Budgetary Institution Roszapovedtsentr, at the conference on the results of the expedition.

Among the technologies used by scientists were Orlan unmanned aerial vehicles (UAVs) and real-time data analysis systems based on artificial intelligence (AI). With their help, the expedition members tracked, in particular, the population of polar bears and the birthplaces of their offspring on Wrangel Island and the Bear Islands.

The data obtained will form the basis of Norilsk Nickel’s corporate system for managing the impact on biodiversity, and will also be used to develop programs for its conservation and monitoring. Norilsk Nickel openly talks about new projects and changes taking place in ecosystems.

“The resulting picture of the state of the environment and biodiversity has already allowed us to adjust current environmental programs,” said Andrey Grachev, vice president for federal and regional programs at Norilsk Nickel.

“Caring for nature, reducing anthropogenic impact, and developing environmentally effective solutions are the basis of responsible business.”
