The Laptev Sea (, ''more Laptevykh'') is a marginal sea of the Arctic Ocean. It is located between the northern coast of Siberia, the Taimyr Peninsula, Severnaya Zemlya and the New Siberian Islands. Its northern boundary passes from the Arctic Cape to a point with co-ordinates of 79°N and 139°E, and ends at the Anisiy Cape. The Kara Sea lies to the west, the East Siberian Sea to the east. The sea is named after the Russian explorers Dmitry Laptev and Khariton Laptev; formerly, it had been known under various names, the last being Nordenskjold Sea (), after explorer Adolf Erik Nordenskiöld. The sea has a severe climate with temperatures below 0 °C (32 °F) over more than 9 months per year, low water salinity, scarcity of flora, fauna and human population, and low depths (mostly less than 50 meters). It is frozen most of the time, though generally clear in August and September. The sea shores were inhabited for thousands of years by indigenous tribes of Yukaghirs and then Evens and Evenks, which were engaged in fishing, hunting and reindeer husbandry. They were then settled by Yakuts and later by Russians. Russian explorations of the area started in the 17th century. They came from the south via several large rivers which empty into the sea, such as the prominent Lena River, the Khatanga, the Anabar, the Olenyok, the Omoloy and the Yana. The sea contains several dozen islands, many of which contain well-preserved mammoth remains. Major human activities in the area are mining and navigation on the Northern Sea Route; fishing and hunting are practised but have no commercial significance. The largest settlement and port is Tiksi. ==Extent== The International Hydrographic Organization defines the limits of the Laptev Sea as follows:
Using current geographic names and transcription this definition corresponds to the area shown in the map. # The sea's border starts at Arctic Cape (formerly Cape Molotov) on Komsomolets Island at and connects to the southeastern cape of the island. # The next segment crosses Krasnoyarmyy Strait and leads to Cape Vorochilov on October Revolution Island and afterwards through that island to Cape Anuchin at . # Next, the border crosses Shokalsky Strait to Cape Unslicht at on Bolshevik Island. It goes further through the island to Cape Yevgenov at . # From there, the border goes through Vilkitsky Strait to Cape Pronchishchev at on the Tamyr peninsula. # The southern boundary is the shore of the Asian mainland. Prominent features are the Khatanga Gulf (estuary of the Khatanga river) and the delta of the Lena River. # In the east, the polygon crosses the Dmitry Laptev Strait. It connects Svyatoy Nos at with Cape Vaguin at in the very east of Bolshoy Lyakhovsky Island. # Next, the Laptev Sea border crosses Eterikan strait to Little Lyakhovsky Island (aka Malyi Island) at up to Cape Madvejyi. # Finally, there is a segment through Kotelny Island to its northernmost cape . # The last link reaches from there back to Arctic Cape. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Laptev Sea」の詳細全文を読む スポンサード リンク
