Indian Ocean response to rising sea-level (INDOCRISIS)

苏门答腊西部沿海地区对印度洋大规模气候异常的发展至关重要。局部海面和温跃层温度的变化不仅影响这一区域的大气对流和降雨，而且影响整个地球仪。对印度洋和周围陆地未来和过去气候的模拟在很大程度上仍然不确定，因为模型在再现这里的气候条件方面存在缺陷。特别是，自末次冰盛期以来，海平面在塑造气候条件方面的作用存在争议，无论是在模拟还是在印度洋气候的重建中。建议重建平均每年的海面和温跃层温度与降雨同位素在西苏门答腊近海的三个沉积记录，自末次冰期以来。此外，还将在五个不同的海平面测量海面和温跃层温度的范围，以评估这些期间这些参数的范围（或稳定性）。这一奋进可以检测海平面的变化是否能够改变该地区的海洋和大气条件，从而能够触发整个流域的环流和降雨异常。

Coastal regions offshore west Sumatra are critical for the development of largescale climate anomalies across the Indian Ocean. Changes in local sea surface and thermocline temperatures affect atmospheric convection and rainfall not only in this region but also across the globe. Simulations of future and past climate of the Indian Ocean and the surrounding landmasses remain uncertain in large part because of the deficiencies of the models in reproducing climate conditions here. In particular, the role of sea-level in shaping climate conditions since the Last Glacial Maximum is disputed, both in simulations and in reconstructions of the Indian Ocean climate. It is proposed to reconstruct mean annual sea surface and thermocline temperatures together with rainfall isotopes in three sedimentary records offshore west Sumatra since the Last Glacial Maximum. In addition, the range of sea surface and thermocline temperatures will be measured in five different sea-level stands in order to assess the range (or stability) of these parameters during those periods. This endeavor allows detecting whether changes in sea-level were capable of changing the ocean and atmosphere conditions in this region that are capable of triggering basin-wide anomalies in circulation and rainfall.
