Expedition participants visit Matveev Island and an abandoned settlement by a lighthouse. The coast of the island is a favored location for Atlantic walruses: a large haulout is located here. The Marine Mammal Council experts, who joined the expedition yesterday, are conducting research works. They have changed trail cameras they had left here a year ago.

After the works on the island, Kartesh departs to conduct research work on the Atlantic walrus nutritive base in the adjacent waters.
