Current World Environment 2020
義弘 藤原, Yoshihiro FUJIWARA

Summary

This cruise report documents research objectives including assessment of marine plastic pollutants and their ecosystem impacts, evaluation of biodegradable plastic deterioration in deep-sea environments, and development of hyperspectral camera methods for automatic microplastic analysis. The expedition contributed to understanding microplastic transport processes and long-term plastic behavior in deep ocean environments.

Understanding the current situations of marine pollutants, especially plastics and assessing their impact on marine ecosystems ; Evaluation test for deterioration of biodegradable plastics under deep-sea environment ; Establishment of analysis method related to "Development of automatic microplastic analysis using hyperspectral camera" ; Field and laboratory studies on plastic deterioration under deep-sea environment ; Elucidation of the transportation process of microplastics in marine environment ; Outreach on marine plastics
