Report of the 4th ocean plastics research society in Environmental and Food Unit

Marine Science Group from Environment and Food Unit held the fourth internal ocean plastics research society on February 14.

The aim of this society series is to facilitate the exchange of information regarding ocean plastic research, and the Marine Science Group from the Environment and Food Unit has been organizing it since this year.

In the fourth installment of our research seminar series, we were honored to host Dr. Takahito Ikenoue, Researcher, Marine Plastics Research Group, Research Institute for Global Change (RIGC), Japan Agency for Marine-Earth Science and Technology. Under the title “Observations of Microplastics in the Arctic Ocean and Northern Pacific: Towards Understanding the Missing Sync,” he shed light on the necessity of comprehensive research, drawing from his own research activities, amidst the current situation where the majority of marine plastics are unaccounted for. Mr. Ikegami discussed the accumulation of sinking particles, sediments on the seabed, and water column analysis, emphasizing the importance of understanding these aspects for resolving the mystery of missing plastic in the oceans.

Associate Professor. Yusuke Okazaki, Department of Earth and Planetary Sciences, Kyushu University also shared his research project titled “Marine Particle Settling and Deposition Processes: Diatom Mat Sediment Found in the Southern Ocean”.

The participants from various research fields had numerous questions and opinions, and the event concluded successfully.

Thank you very much to all of you for your participation.
