Okhotsk High Sea
The open Sea of Okhotsk lies west of Kamchatka and the northern Kurils. It is one of the southernmost seas in the Northern Hemisphere with extensive seasonal ice. Ice forms first along the northern coasts and expands through winter, while the West Kamchatka Current carries relatively warm Pacific water northward along the peninsula. Winds and currents shape the ice's advance and retreat across this cold inland sea.
