"The southeastern part of the Barents Sea is faced with the rapid development of shipping and mineral extraction. All this could put walruses at risk", explains Margarita Puhova, coordinator for marine biodiversity at WWF Russia.
The long-term project used a wide range of existing and novel research methods, from on-the-ground observations to aerial surveys, satellite tagging and genetic studies. The researchers also used highly-detailed satellite imagery to estimate the size of walrus gatherings on land, or haulouts.
"Ten years ago, we had very little reliable data on the current state of the population - only scraps of information from a single expedition", says Puhova. "To develop measures for the conservation of the Atlantic walrus, first we needed to study them."
