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.

IODP 302号考察队（ACEX）从北极采集的北极岩芯的初步结果表明，在全球极端温暖的始新世早期，北极没有冰，在非常咸的近地表沃茨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和全球海洋之间可能的相互作用，并通过全球变冷来追踪这些相互作用，然后在北冰洋沃茨中开发历史Sr和Nd同位素。这项研究将涉及研究生，并涉及全球气候变化问题。
