Sedimentation in Thermospheric and Psychrospheric Environments: A Comparison of Western Pacific Basins

&gt；&gt；B%&gt；&gt；&gt；B%&gt；&gt；&gt；。J·H·桑内尔博士获得资金，继续他与科利斯博士(杜克大学)一起调查苏鲁海和南中国海的第四纪古海洋学。这两个盆地的泥沙沉积受夹杂的底床控制，极大地抑制了底水的交换。在1988年的一次航行中，桑内尔和科利斯博士收集了沿这些岩床的岩心横断面，以记录在晚更新世冰川/间冰期旋回期间变化的古海洋条件。凭借目前的奖项，他们将完成岩心分析，并将其扩展到包括对盒子岩心中收集的活的海底有孔虫的研究。以这种方式获得的生态和同位素信息将被用来重建该地区晚第四纪古环境的变化史。他们的数据还将用于重建赤道西太平洋季风环流的第四纪晚期历史；他们打算将这一历史与西北印度洋的其他研究结果进行比较。

Dr. Thunnel is awarded funds to continue his research with Dr. Corliss (Duke University) in the investigation of the Quaternary paleoceanography of the Sulu and South China Seas. Sediment deposition in these two basins is controlled by intervening sills that greatly inhibit the exhange of bottom water. During a cruise in 1988 Drs. Thunell and Corliss collected transects of cores along these sills to document changing paleoceanographic conditions during glacial/interglacial cycles of the late Pleistocene. With their present award they will complete their core analyses and extend them to include studies of living benthic foraminifera collected in their box cores. The ecologic and isotopic information derived in this manner will be used to reconstruct the history of changes of the late Quaternary paleoenvironments of the region. Their data will also be used to reconstruct the late Quaternary history of monsoonal circulation of the western equatorial Pacific; they intend to compare this history with results derived from other studies of the NW Indian Ocean.
