Full results will probably be released in Q1, 2023, available via SB-RAS. Initially designed to assess the environmental impact of the fuel spill by Norilsk Nickel, it included surface waters, soils, sediment, vegetation, animals and permafrost. They also recommend additional measures to remove pollution and rehabilitate polluted ecosystems.

Additional biodiversity studies assessed environmental impact from Norilsk’s operations to help inform future Arctic eco-assessment and planning. Scientists lived in the region and completed fieldwork including soil and water sampling to review the affected ecosystems. Additional permafrost field studies were completed by collecting samples from boreholes and sensors.

Geologists, zoologists, biochemical, microbiologists and other scientists also took samples which will provide useful baselines for future Arctic and climate research beyond the original requirements of the expedition. They have 1500 samples from over 30 zones:
