Nakayama Research Group

Hokkaido University  – School of Environmental Science / Institute of Low Temperature Science
Our group will move to Dartmouth College in December 2024. 

New student positions at Dartmouth College  starting in 2025  

I am seeking outstanding graduate students who are interested in working on ocean modeling and data analysis to start in 2025. A solid background in fluid mechanics and programming is preferred. The candidate will likely have the opportunity to participate in an expedition to Antarctica during their PhD programs.  If interested, please send me an email with a brief description of your research interests and background.

New postdoc positions at Dartmouth College  starting in 2025

I am seeking an outstanding postdoc who is interested in working on ocean modeling involving the application of adjoint sensitivities for polar oceans to start in 2025. A solid background in fluid mechanics, programming, and mathematics is preferred. If interested, please send me an email with a brief description of your research interests and background.


Welcome to Yoshihiro Nakayama's Group in the School of Environmental Science/Institute of Low Temperature Science, Hokkaido University.  

The primary interest of our research group is to improve our understanding of the past, present, and future state of the Southern Ocean and identify triggers of ocean warming and Antarctic ice loss on various time scales by (a) conducting oceanographic observations, (b) improving ocean simulations achieving high model-data agreement, and (c) developing ice-ocean coupled simulation

Our research group is growing since  it was established in 2019. Currently, we have one doctoral and three master's students. You can join our group from the Graduate School of Environmental Science in the course of Atmosphere-Ocean and Climate Dynamics.  Check out also the opportunity to join our team. We are active on social media, outreach activities (e.g., Antarctic candle workshop), and are connecting our science with the general public.

Antarctic ice is losing ice contributing to sea-level rise. Its mass loss may be accelerating. In the past decade, it is becoming possible to observe the Southern Ocean, especially ice-covered continental shelf areas, at an unprecedented level of spatial and temporal details. This is an exciting time of exploration and discovery as we need to project accurately what might come ahead in the future to prevent and mitigate the impact on human society.
