Vostochno-Sibirskoe more; East Siberian Sea

Japanese: 東シベリア海 - ひがしシベリアかい（英語表記）Vostochno-Sibirskoe more; East Siberian Sea

It is one of the marginal seas of the Arctic Ocean. It is an area bounded by the Siberian coast to the south, the Novosibirsk Islands to the west, and Wrangel Island to the east. It is connected to the Laptev Sea in the west and the Chukchi Sea in the east. It stretches about 1,200 km from east to west, has an area of about 940,000 km2, ^and has a continental shelf 700 km wide. The average depth in the north is 45 m, but it is deeper in the east. The Indigirka River and the Kolyma River flow into it, and in summer the waterways along the south coast are navigable. The main port is Ambalchik at the mouth of the Kolyma River. This was the last difficult spot during the development of the Northeast Passage, and the first completed voyage was made in 1878 by N. Norenscher's Vega.

北極海の縁海の一つ。シベリア沿岸を南限に，西はノボシビルスキー諸島，東はウランゲリ島で限られる海域。西部でラプテフ海に，東部でチュクチ海に通じる。東西約 1200km，面積約 94万 km²，大陸棚は幅 700kmにわたり発達している。北側の平均深度は 45mであるが，東側はそれより深い。インジギルカ川，コルイマ川などが流入し，夏季には南岸沿いの水路も可航となる。主要港はコルイマ川河口のアンバルチク。北東航路の開拓時代に最後の難所となったところで，初の完航は 1878年 N.ノーレンシェールの『ベガ』号によって行われた。
