Collaborative Research: History and Timescale of Paleoceanographic Change in the Arctic Ocean

IODP 302号远征队（ACEX）从北极恢复的北极岩心的初步结果表明，在全球极端变暖的始新世早期，北极是无冰的，在非常咸水的近地表水中支持着一个高产的生态系统。根据该奖项，pi建议在这些极端温暖的时期限制北极与全球海洋之间可能的相互作用，并通过开发北冰洋水域Sr和Nd同位素的历史，通过全球变冷来追踪这些相互作用。这项研究将涉及研究生，并解决全球气候变化问题。

Initial results from Arctic cores recovered by the IODP Expedition 302 (ACEX) from the Arctic indicate that during the early Eocene time of extreme global warmth the Arctic was ice-free and supported a highly productive ecosystem in very brackish near surface waters. Under this award, the PIs propose to constrain the likely interactions between the Arctic and the global ocean during these extremely warm times and to trace these interactions through the global cooling that followed by developing a history Sr and Nd isotopes in Arctic Ocean waters. This study will involve graduate students and addresses the question of global climate change.
