亲潮

亲潮与黑潮在北海道附近碰撞。当两个洋流发生碰撞,它们造成漩涡。在表层水生长的浮游植物沿着这些漩涡的边界变得密集,追查出来的水的运动踪迹。
围绕着日本列岛的洋流: 1.黑潮 2. 黑潮扩展 3. Kuroshio countercurrent 4. 日语:-対马海流-* 5. 日语:-津軽暖流-* 6. 日语:-宗谷暖流-* 7. 亲潮 8. The Liman Current

亲潮,或又称为千岛群岛洋流,是一股亚极地的冷洋流,自北极海逆时钟方向向南经由白令海流往西北太平洋,在日本东部海域与黑潮会合形成北太平洋洋流。亲潮对于俄罗斯远东地区的气候产生极大的影响,这点在俄国沿太平洋地区的堪察加半岛与楚科奇半岛的林木线可以观察到,这两个地区的林线比内陆的西伯利亚地区还要低纬度十度左右,这是因为寒冷的洋流将其经过地区的气温降低到树木无法生长的程度。

亲潮丰富的养分使得其经过的水域成为富裕的渔场。亲潮的经过也使得海参崴成为最靠近赤道但在冬季时仍需要破冰船的港口。另外在冰河时期时,降低的海平面造成了白令海峡陆桥,这使得冰河时期的亲潮无法到达它今日所能到达的纬度,日本的东北地方与北海道虽然处在东亚地区唯一有足够降雪量以产生冰河,但是并未像欧洲与北美洲在冰河时期时被冰河大面积的覆盖,反而只有在高海拔地区才有些许的冰。而这点则解释了为什么东亚地区保留了96%上新世的植物,而欧洲却只有27%。

Oyashio Current 亲潮

Oyashio(亲潮, "Parental Tide"), also known as Oya Siwo, Okhotsk or the Kurile current, is a cold subarctic ocean current that flows south and circulates counterclockwise in the western North Pacific Ocean. The waters of the Oyashio Current originate in the Arctic Ocean and flow southward via the Bering Sea, passing through the Bering Strait and transporting cold water from the Arctic Sea into the Pacific Ocean. It collides with the Kuroshio Current off the eastern shore of Japan to form the North Pacific Current (or Drift). The nutrient-rich Oyashio is named for its metaphorical role as the parent(oya) that provides for and nurtures marine organisms.
