St. Lawrence Island () is located west of mainland Alaska in the Bering Sea, just south of the Bering Strait. The village of Gambell is located on the northwest cape, from the Chukchi Peninsula in the Russian Far East. The island is part of Alaska, but closer to Siberia than to the Alaskan mainland. St. Lawrence Island is thought to be one of the last exposed portions of the land bridge that once joined Asia with North America during the Pleistocene period.〔(【引用サイトリンク】work=University of Missouri-Columbia Museum of Anthropology )〕 It is the sixth largest island in the United States and the 113th largest island in the world. ==Geography== The United States Census Bureau defines St. Lawrence Island as Block Group 6, Census Tract 1 of Nome Census Area, Alaska.

The island has no trees, and the only woody plants are Arctic willow, standing no more than a foot (30 cm) high. The island's abundance of seabirds and marine mammals is due largely to the influence of the Anadyr Current, an ocean current which brings cold, nutrient-rich water from the deep waters of the Bering Sea shelf edge. To the south of the island is a persistent polynya, formed when the prevailing winds from the north and east blow the migrating ice away from the coast.〔(【引用サイトリンク】work=Polar Research at UW Oceanography )〕 The climate of Gambell is: 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「St. Lawrence Island」の詳細全文を読む スポンサード リンク
