    "abstract": "The International Bathymetric Chart of the Arctic Ocean (IBCAO) is a gridded continuous terrain model covering ocean and land of the Arctic region. The International Bathymetric Chart of the Arctic Ocean (IBCAO) was initiated 1997 and has since been the authoritative source of bathymetry for the Arctic Ocean. In 2017, the IBCAO merged its efforts with the Nippon Foundation-GEBCO Seabed 2030 Project, with the goal of mapping the global seafloor by 2030. \r\n\r\nThe aim of the IBCAO is to develop a digital grid based of all available bathymetric data north of 64° North, for use by mapmakers, researchers, institutions, and others whose work requires a detailed and accurate knowledge of the depth and the shape of the Arctic seabed. The IBCAO grid is used for the Arctic region in the global GEBCO grid.\r\n\r\nThe IBCAO Product Collection encompasses all digital products released in all formats since 2001. The IBCAO Product Collection contains all available formats and datasets for the latest IBCAO release, alongside documentation and terms of use:\r\n\r\n• IBCAO Version 5 - released July 2024 -  100, 200, 400 metre grid cell spacing - NetCDF and data GeoTIFF format. Accompanied by a Type Identifier Grid (TID) that indicates the type of source data that the corresponding grid cell in the bathymetric grid cell is based on.\r\n\r\n\r\nThe IBCAO Product Collection also contains all available datasets in all formats for legacy IBCAO releases, alongside their documentation and terms of use:\r\n\r\n• Version 4.2.13 - released July 2023 \r\n• Version 4.2 - released August 2022 \r\n• Version 4.1 - released July 2021 \r\n• Version 4.0 - released March 2020 \r\n• Version 3.0 - released June 2012 \r\n• Version 2.23 - released March 2008 \r\n• Version 1 - released July 2001",
