Sub-centennial-scale Gulf of Mexico sea-surface temperature variability during the Holocene epoch

该奖项的目的是重建在亚百年到千年的分辨率全新世SST和d180 sw的变化从两个马里恩杜弗雷纳核心恢复在墨西哥湾的虎鲸盆地。 岩芯全新世厚度为300 ~ 500 cm，由于斜坡盆地的卤水入渗而成层。 将用于确定气候变率的SST代用指标包括G的氧同位素。ruber、浮游有孔虫组合和Mg/Ca比值。

The aim of this award is to reconstruct at sub-centennial to millennial resolution the Holocene SST and d180sw variability from two Marion Dufresne cores recovered from the Orca Basin in the Gulf of Mexico. The cores have 300 to 500 cm of Holocene and are laminated due to brine infiltration of a slope basin. The SST proxies that will be used to determine climate variability include oxygen isotopes of G. ruber, planktonic foraminiferal assemblages, and Mg/Ca rations.
