Bathymetry And Global Relief. Acknowledging that the rate at which new seafloor is currently being mapped andor data are being made publicly available remains unsatisfactorily low a recent consortium have committed to the ambitious goal of compiling a global highresolution between 800 and 100 m bathymetric database by 2030 as part of the Nippon FoundationGEBCO Seabed 2030 Project Mayer et al 2018. The model integrates land topography and ocean bathymetry and is available in two grid versions. NOAA National Oceanic and Atmospheric Administration is the primary source of bathymetric data for the worlds oceans. Interagency Elevation Inventory displays high-accuracy topographic and bathymetric data for the United States and its territories.
See their Bathymetry and Global Relief website. ETOPO1 1 Arc-Minute Global Relief Model developed by the National Geophysical Data Center NGDC at National Oceanic and Atmospheric Administration NOAA. Please use the new ETOPO1 Global Gridded Relief Model. It is a product of N6DC. NOAA National Oceanic and Atmospheric Administration is the primary source of bathymetric data for the worlds oceans. The model integrates land topography and ocean bathymetry and is available in two grid versions.
Ice Surface and BedrockThis data visualization utilized the ETOPO1 Ice Surface grid which depicts the.
Data were converted to the PanMap layer format in 14 contour lines from 500 to 7000 meter in steps of 500 m. Images derived from data offered by the NOAA National Geophysical Data Center NGDC Marine Geology Geophysics Division and collocated World Data Service for Geophysics. ETOPO1 1 Arc-Minute Global Relief Model developed by the National Geophysical Data Center NGDC at National Oceanic and Atmospheric Administration NOAA. ETOPO1 is a 1 arc-minute global relief model of Earths surface that integrates land topography and ocean bathymetry. New method for compilation of global seafloor bathymetry that preserves the native resolution of swath sonars is presented. Two-minute gridded global relief for both ocean and land areas are available in the ETOPO2v2 2006 database.
