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

IODP探险302(ACEX)从北极取回的北极岩芯的初步结果表明，在始新世早期全球极端温暖时期，北极没有冰，并在非常微咸的近地表水域支持了一个高生产力的生态系统。根据这一奖项，私人投资机构建议限制北极和全球海洋在这些极端温暖的时期可能发生的相互作用，并通过随后的全球变冷来追踪这些相互作用，然后在北冰洋水域中发展历史上的锶和钕同位素。这项研究将涉及研究生，并解决全球气候变化的问题。

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.
