摘要/Abstract

摘要：

跨菲律宾海的重复断面水文观测揭示: 菲律宾海底层水体从1990s到2010s增暖了0.002~0.01℃。在西马里亚纳海盆和四国海盆, 较冷的下层绕极深层水(Lower Circumpolar Deep Water, LCDW)减少, 较暖的LCDW增加; 而在菲律宾海盆, 较冷的变性LCDW减少, 较暖的变性LCDW增加。菲律宾海盆4000dbar的热通量是0.0413W·m^-2, 而西马里亚纳海盆和四国海盆的是0.0221W·m^-2。菲律宾海盆由于深层海洋热膨胀引起的局地海平面上升速度是0.0621mm·yr^-1, 而西马里亚纳海盆和四国海盆的是0.0333mm·yr^-1。

Abstract:

Repeated trans-Philippine-Sea hydrographic observations reveal that the bottom water in the Philippine Sea has warmed up by about 0.002~0.01℃ between 1990s and 2010s. In the West Mariana Basin and the Shikoku Basin, the colder portion of the Lower Circumpolar Deep Water (LCDW) decreased while the warmer portion increased. In the Philippine Basin, the colder portion of modified LCDW decreased while the warmer portion increased. The heat flux at the 4000-dbar isobath is 0.0413W·m^-2 in the Philippine Basin and 0.0221W·m^-2 in the West Mariana Basin and the Shikoku Basin. The sea level rise is 0.0621mm·yr^-1 in the Philippine Basin and 0.0333mm·yr^-1 in the West Mariana Basin and the Shikoku Basin due to deep ocean thermal expansion.

Key words: warming, bottom water, Philippine Sea
