Dr Hakase Hayashida

Hakase is a Research Associate of the ARC Centre of Excellence for Climate Extremes (CLEX).

Hakase completed his PhD in Earth and Ocean Sciences at the University of Victoria, Canada, in 2018, where he studied the sea-ice and oceanic production and emissions of the climate-active gas dimethylsulfide in the Arctic. Prior to that, he obtained his B.Sc. and M.Sc. at Memorial University of Newfoundland, Canada, where he studied the physical and biogeochemical processes in the Labrador Sea.

Now at the Institute of Marine and Antarctic Science (IMAS - UTAS) , he investigates the impacts of mesoscale eddies, marine heatwaves, and anthropogenic climate change on the Southern Ocean biogeochemical dynamics.

Hakase’s research interests include understanding of biogeochemical processes in the ocean and sea ice, developing process-based numerical models of sea-ice and ocean biogeochemistry, and assessing the projected changes in sea-ice and ocean biogeochemistry due to climate change. Sea-ice and ocean biogeochemical cycles play a crucial role in the global cycle of key elements and climatically-important gases.

Hakase is currently involved in two international projects: Ocean Model Intercomparison Project (OMIP) and Ice Algae MIP (IAMIP). These projects are primarily aimed at understanding systematic bias in the state-of-the-art global sea ice-ocean models contributing to the Coupled Model
