单位： Thayer School of Engineering，Dartmouth College，USA

报告人简介：Dr. Nakayama is an Assistant Professor at the thayer School of Engineering at Dartmouth College. He received his Ph.D. in natural science from the Universität Bremen (Germany) and completed his postdoc at NASA-JPL with Dr. Dimitris Menemenlis. He received prestigious early career awards from the Oceanographic Society of Japan and the Inoue Research Foundation. The key success of his track record is the combined use of observations and state-of-the-art numerical modeling (ECCO) to understand the rapidly changing polar oceans and ice sheets. Throughout his career, he has published over 35 peer-reviewed publications including Nature Geosciences and Nature Communications.

报告内容简介：How fast Antarctica will lose ice and contribute to sea-level rise has become one of today’s most urgent scientific questions. Antarctic ice-sheet mass loss is primarily triggered by the ocean, but relatively little is understood about the drivers of ocean warming where it matters – at the ice sheet margin – nor about the impact of ice-shelf melting on the ocean. I (a) conduct oceanographic observations, (b) improve ocean simulations achieving high model-data agreement, and (c) develop ice-ocean coupled simulations to better understand the past, present, and future state of the Southern Ocean and identify the causes of ocean warming and Antarctic ice loss on various time scales. In this presentation, I will review the literature, including work from my group, that shows how ocean heat intrudes towards the West Antarctic ice shelves, the most rapidly melting region in Antarctica, and controls ice shelf melting. I will also discuss ongoing projects – using both data acquisition and modeling – aimed at a deeper understanding of the processes that control the future of the Antarctic ice sheet.
