The Global Ocean Science Report (GOSR) 2020, published by the Intergovernmental Oceanographic Commission of UNESCO (IOC) on December 4, 2020, analyzes various aspects of the current situation of ocean science, such as scientific papers, funding, and researchers, and compiles those results. It also includes recommendations, based on the data analysis, regarding measures that each country should consider. I have the highest hopes that the edition’s publication and recommendations will spur ocean science in Japan, a self-professed maritime nation, as well as the global development of ocean science, leading to the successful implementation of the UN Decade of Ocean Science for Sustainable Development and achievement of the SDG14.
