SEMINARS
The AAPP, coordinated by Dr Pat Wongpan, is proud to host a visit by Assistant Professor Yoshihiro Nakayama from the School of Environmental Science/Institute of Low Temperature Science at Hokkaido University, Japan, during March 20-24, 2023.
Asst Prof Nakayama will present three seminars on the topic of:
How can we better understand what is happening in the Southern Ocean and Antarctica?
Abstract: 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 by 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 modelling – aimed at a deeper understanding of the processes that control the future of the Antarctic ice sheet.
Bio: Asst Prof Nakayama earned a Master’s degree with distinction from the Graduate School of Environmental Science, Hokkaido University in Japan. He received a PhD in 2015 from the University of Bremen/Alfred Wegener Institute (AWI) in Germany, where he worked on the interactions between the Southern Ocean and West Antarctic ice shelves using oceanographic observations and numerical modelling. Upon graduation, He was awarded a NASA Postdoctoral Program (NPP) fellowship at the Jet Propulsion Laboratory (JPL). At JPL, he continued his research on the development of regional models and ocean state estimates, focusing on the important Amundsen Sea region of Antarctica.
Currently, he is an Assistant Professor at Hokkaido University. His unique background and experience working in Asia, Europe, and the USA provide extensive opportunities for world-class collaborative research. He is an International Association for the Physical Sciences of the Oceans (IAPSO) vice chair for Joint Commission on Ice- Ocean Interactions (JCIOI) with Dr McCormack and they aim at enhancing connections between researchers and facilitating the understanding, observing, and modelling of ice-ocean interactions. He is also a member of the Southern Ocean Observing System (SOOS).

This visit is to deliver research seminars and to promote the Annual Symposium of the Japan Society for the Promotion of Science Alumni Association in Australia (JSPSAAA) that will be held on 22-23 November at the Shine Dome, Australian Academy of Science in Canberra. The theme for this year is "Australia-Japan Science and Innovation Partnership". The Annual Symposium is sponsored by JSPSAAA, Japan Society for the Promotion of Science (JSPS), Australian Academy of Science, Australia Japan Foundation, and the University of Canberra.
