为PI提供了资金，使他能够继续研究在“正常和厄尔尼诺年”期间从加利福尼亚湾收集的各种沉积物和沉积物陷阱材料。沉积物捕集器材料将记录墨西哥湾沉积物输入的季节性循环，以及在正常和厄尔尼诺条件下控制这一循环的气候因素。通过沉积物岩心研究，构建了近13k年的年-年代际尺度气候变化记录。这项提议的研究的意义超出了墨西哥湾的边界。它将提供正常条件下气候变化和厄尔尼诺扰动对整个盆地影响的详细图像。
英文摘要
Thunnell 9301413 Funds are provided to allow the PI to continue his study of the varved sediments and sediment-trap material from the Gulf of California collected during "normal and ElNino years. Sediment trap material will document the seasonal cycle of sediment input into th Gulf and the climatological factors that control this cycle during both norrnal and El Nino conditions. From sediment core study the record of annual to decadal scale climate changes will be constructed for the past 13 k years. The proposed study has significance beyond the boundaries of the Gulf. It will provide a detailed picture of the basin-wide impacts of climate changes during normal conditions and the El-Nino perturbations.
