The Sea of Okhotsk is a marginal sea located in the northwestern Pacific Ocean. It is bordered by Russia to the west and north, and Japan to the south. The sea covers an area of approximately 1.6 million square kilometers and is known for its rich marine biodiversity, including various fish species and marine mammals. The Sea of Okhotsk is also significant for its economic resources, particularly fishing and oil exploration. The sea experiences harsh weather conditions, especially in winter, with ice forming in many areas. Its unique geography and climate make it an important region for both ecological and economic activities.
