Symposium: “Marine Environmental Impact Assessment under a Changing Climate”

The Advisory Group on Marine Environmental Issues, the Oceanographic Society of Japan (JOS) is planning a symposium titled “Marine Environmental Impact Assessment under a Changing Climate” on September 25, the final day of the JOS 2025 Autumn Meeting. The symposium is convened by WPI-AIMEC Unit Leader Dr. Michio Kawamiya (Principal Researcher, JAMSTEC). WPI-AIMEC Unit Leader Prof. Michio Kondoh (Tohoku University’s Graduate School of Life Sciences) will participate as a speaker.

As noted in the conference schedule (see link), the symposium will be held in Venue 4, and is planned as a hybrid event with online streaming.

Attendance is free and open to both members and non-members of JOS. If you wish to attend (especially online), please register using the application form below.

Purpose

Global climate change, as well as the increasing frequency of extreme weather events in Japan, changes in water resources and vegetation, and fluctuations in marine resources in surrounding waters, have led to a growing recognition that the impacts of global warming are becoming increasingly evident across a wide range of areas. As a result, urgent national-level responses are being sought. The “Climate Prediction Dataset 2022” (hereinafter referred to as DS2022), published under the initiative of the Ministry of Education, Culture, Sports, Science and Technology and the Japan Meteorological Agency, contains climate prediction data covering a wide range of fields, including the marine environment, and is being utilized in various related fields such as agriculture, forestry, fisheries, and flood control. High-resolution prediction data for the waters around Japan is available at a resolution of 2 km until 2100. This symposium aims to provide an overview of the current state of research on global climate change and its impact on coastal areas, introduce the content and usage of environmental data such as DS2022 and the environmental DNA dataset ANEMONE, and promote awareness of these data to facilitate reliable predictions of future changes in marine-related fields.
