TALK

• What if we can predict phytoplankton blooms two months in advance?

• Dr. Hakase Hayashida, the Application Laboratory of the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) in Yokohama, Japan

In this seminar, a short-range ocean prediction system known as the Japan Coastal Ocean Predictability Experiment (JCOPE) and its ongoing development to incorporate marine biogeochemistry will be presented. JCOPE has been providing routine two-month ocean weather forecasts around Japan since 2001. It does so by combining a numerical ocean model with satellite and autonomous float observations to generate a realistic present condition of the ocean and simulating possible future conditions that are driven by atmospheric weather forecasts. Both the best state estimate of the past (reanalysis) and the prediction of ocean temperature, salinity, current, and sea surface height can be made freely available for non-profit and scientific research purposes. Currently, the possibility of incorporating ocean biogeochemistry into JCOPE is explored. This integration is expected to enhance JCOPE’s capability by providing information relevant to ocean ecosystem health, such as nutrient concentrations, phytoplankton biomass, dissolved oxygen levels, and pH. While this development is still in its infancy, its potential application for scientific research and sustainability initiatives will be discussed during the seminar. It’s also noted that JCOPE has a configuration that is beyond the northwest Pacific, and therefore, may also be of great interest to students and early career researchers in Asia and Oceania.

Our Speaker

Hakase Hayashida is a Researcher at the Application Laboratory of the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) in Yokohama, Japan. He is broadly interested in understanding the role of phytoplankton in marine biogeochemistry and ecosystems. Hakase was born and raised in Nagasaki, the home of great seafood. At the age of 15, he moved to Nova Scotia, Canada, for studying English during high school where he gained much interest in marine environmental issues. After high school, he moved further east to Newfoundland to pursue BSc in Environmental Physics and MSc in Physical Oceanography at Memorial University of Newfoundland. He figured it was time to move a bit closer back to Japan, so decided to pursue PhD in Earth and Ocean Sciences at the University of Victoria, Canada. He then moved down under to take on a postdoc position at the University of Tasmania, Australia. In 2022, he moved back to Japan after spending nearly two decades overseas and joined JAMSTEC with an ambition to develop a short-range prediction model for phytoplankton blooms in the northwest Pacific and beyond that can be used for fisheries and aquaculture management. He enjoys travelling and camping with his family.
