2024年1月3日 · The Ocean Basemap includes bathymetry, surface and subsurface feature names, and derived depths. This map is designed to be used as a basemap by marine GIS professionals and as a reference map by anyone interested in ocean data.

NCEI is the official distribution point for NOS bathymetric maps, bathymetric/fishing maps, regional maps, geophysical maps, and preliminary maps. Topographic maps of the sea floor. Detailed depth contours provide the size, shape and distribution of underwater features.

2022年7月20日 · Topographic maps show the physical shape of dry land using elevation values. Bathymetric maps show the physical shape of the seafloor using depth values. Together, topographic and bathymetric maps show the physical features on the Earth’s surface.

2025年1月13日 · BlueTopo is a compilation of the nation's best available bathymetric data. In the same way that a topographic map details the height of land, BlueTopo details the depth of lake beds and seafloor beneath navigationally significant U.S. waters.

2022年6月6日 · The California Seafloor Mapping Program (CSMP) is a cooperative program to create a comprehensive coastal and marine geologic and habitat base map series for all of California's State waters.

2012年2月10日 · The Ocean Basemap includes bathymetry, surface and subsurface feature names, and derived depths. This map is designed to be used as a basemap by marine GIS professionals and as a reference map by anyone interested in ocean data.

Use this interactive map to search and access bathymetric data, including multibeam, singlebeam, lidar, and crowdsourced bathymetry data. NCEI and the IHO Data Center for Digital Bathymetry (DCDB) archive and share depth data acquired by hydrographic, oceanographic, and industry vessels and platforms during surveys or while on passage.

2014年10月9日 · This super-detailed map of the ocean floor's topography is based on satellite measurements of subtle lumps on the ocean's surface. These lumps of water, which are subtle, low, and wide on...
