Tsuyoshi Wakamatsu


Tsuyoshi Wakamatsu is a physical oceanographer. He obtained his PhD at the Hokkaido University in Sapporo (Japan) in 1998, researching swirls in the ocean and how to use data assimilation to study these eddies better.

Wakamatsu is interested in the Arctic Ocean’s biogeochemistry. He investigates elements like chlorophyll, nitrogen, and carbon and their distribution throughout the ocean over time. Studying these elements – some of them being crucial nutrients for marine life – gives us a better understanding of the marine ecosystem and the ocean carbon cycle. Marine monitoring is important to continuously investigate health of ecosystems in the ocean, it is necessary for implementing marine policies, and it can support scientific innovations. The tools that Wakamatsu preferably uses for his work to estimate the biogeochemical state of the Arctic Ocean are models, data assimilation, machine learning, and data analysis methods.
