The 오호츠크해 (Okhotsk Sea) is a marginal sea located in the northwest Pacific Ocean. It is bordered by 러시아 (Russia) to the west, 일본 (Japan) to the south, and the 쿠릴 열도 (Kuril Islands) to the east. The sea is known for its rich marine biodiversity and is an important fishing area. The 오호츠크해 experiences a cold climate, with ice forming in winter, particularly in the northern regions. It plays a significant role in the regional ecosystem and is influenced by the 북태평양 해류 (North Pacific Current), which affects its temperature and salinity.
