中文摘要
北大西洋的Keigwin水团在冰期/间冰期和千年时间尺度上都有变化。在恶劣气候条件下,北部深水受到抑制,中间水流增强,湾流温度和盐度发生变化。现在可以从布莱克和巴哈马的外脊和卡罗莱纳的斜坡上获得长而大直径的岩心。利用地球化学指标,首席研究员将重建末次冰期极大期、冰期低盐度事件和冰期降温事件的深层和中期水文条件。***
英文摘要
9510075 Keigwin Water masses of North Atlantic are known to have varied on glacial/interglacial and millennial time scales. Deep northern water was suppressed during severe climates, intermediate water flow was enhanced and Gulf Stream temperature and salinity varies. Long and large diameter cores are now available from Blake and Bahama outer ridges and the Carolina slope. Using geochemical proxies the principal investigator will recreate deep and intermediate hydrographic conditions for the last glacial maximum, deglacial low salinity event and the deglacial cooling event. ***
