[M-IS09] Ocean Plastics, an earth science perspective

Mon. May 27, 2024 3:30 PM - 4:45 PM 303 (International Conference Hall, Makuhari Messe)

convener:Atsuhiko Isobe(Kyushu University RIAM), Kiichiro Kawamura(Yamaguchi University), Yusuke Okazaki(Department of Earth and Planetary Sciences, Graduate School of Science, Kyushu University), Masashi Tsuchiya(Research Institute for Global Change, Japan Agency for Marine-Earth Science and Technology), Chairperson:Atsuhiko Isobe(Kyushu University RIAM)

Mismanaged plastic wastes accounting for 70% of marine debris remain persistently in the marine environment, even if they are degraded and fragmentized to tiny microplastics. To date, it has been unknown how this anthropogenic, buoyant, and persistent matter which was first appeared in the earth history, contaminates (or is incorporated into) the earth system. The ocean plastic study requires the insight and methodology of a variety of earth sciences such as the oceanography, geology, and palaeontology. Studies on the plastic circulation loaded from the land/atmosphere to upper oceans and bottom sediments, studies on microplastics as a proxy of the "Anthropocene", and studies to establish procedures in monitoring and analyzing macro/microplastics are welcomed.
