[SCG45-01] JAMSTEC Contribution to the NIPPON FOUNDATION-GEBCO SEABED2030 Project
Keywords:GEBCO project, Seabed2030 project, seafloor bathymetry
In October 2019, a new research program called “Mathematical Seafloor Geomorphology” was launched in the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) to establish collaborations between various research fields. One of the major objectives of this program is to contribute to the “Nippon Foundation - General Bathymetric Chart of the Oceans (GEBCO) Seabed 2030 Project.” Efforts are also ongoing to establish a new method for creating high-resolution seafloor bathymetry using machine learning technology.
This is a joint enterprise, being led by an oceanography committee formed by the International Hydrographic Organization (IHO), GEBCO, and the United Nations Educational, Scientific and Cultural Organization Intergovernmental Oceanographic Commission (UNESCO-IOC). GEBCO standardizes the creation of bathymetry maps to fill bathymetric gaps in the world’s oceans. Funded by the Nippon Foundation, the Nippon Foundation - GEBCO Seabed2030 Project started in 2017. In January 2021, UNESCO also started the “UN Decade of Ocean Science for Sustainable Development (2021-2030, hereafter the UN Decade),” and has since collaborated with and supported the “Seabed2030” project. The Hydrographic and Oceanographic Department of the Japan Coast Guard is a formal desk for a coordination engine of Japanese seabed bathymetry data. JAMSTEC is sharing information with the Japan Oceanographic Data Center (JODC), is collecting bathymetry data using six research vessels, and is cooperating with GEBCO’s grid making process. A database site, called “DARWIN,” is being used to display the collected data and provide the bathymetry data obtained so far. Due to the different projection mappings being used by DARWIN and the National Oceanic and Atmospheric Administration (NOAA)/IHO Data Center for Digital Bathymetry (DCDB), this program was corrected and revised in July. The displays of the NOAA/IHO DCDB and DARWIN are jointly integrated and provide bathymetry data globally. A method for generating super-high-resolution topographic data and analyzing gaps where no investigations have yet been conducted has also successfully been developed using mechanical learning. Herein, we would like to outline the current state of bathymetry data collection, introduce a timeline for 2030, and highlight the crowd-sourced development achieved by outreach activities discussions that were held during the GEBCO week Map the Gaps symposium that was performed in January, 2021. We would like to hold your attention to collaborate for data collection, and to ensure complete seafloor mapping.
