U.S. Bathymetric & Fishing Maps - National Oceanic and …
Topographic maps of the sea floor. Detailed depth contours provide the size, shape and distribution of underwater features. The map serves as a tool for performing scientific, engineering, marine geophysical and environmental studies, that are required in the development of energy and marine resources.
Seafloor Mapping - NOAA Ocean Exploration
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.

World Ocean Depth Map - Databayou
This is a Bathymetric Map. It shows the depth of the Ocean Floor around the world. Bathymetry measures the depth of the water in oceans, rivers, or lakes. Bathymetric maps or charts look a lot like topographic maps. They use lines to show the shape and elevation of land features.
Seafloor Mapping - National Centers for Environmental Information
This interactive map gives access to combined bathymetric and topographic data, including the ETOPO Global Relief Model.
Ocean floor features - National Oceanic and Atmospheric Administration
2020年5月1日 · So how do we make maps of the global ocean floor? It turns out that satellites can “see” below the sea surface. With careful processing, small differences in sea surface heights and gravity can reveal detailed maps of the seafloor .

2-minute resolution gridded topography/bathymetry Images created by the NOAA National Geophysical Data Center from bathymetric, topographic, and marine geological and geophysical data.
Sea Floor Mapping - NOAA Ocean Exploration
The publication of Heezen and Tharp’s Physiographic Map of the North Atlantic in 1957 was the first map of the sea floor that enabled the general public to begin to visualize what the ocean floor really looked like. These early maps, based on hundreds of thousands of hand-picked depths, provided the context for the plate tectonics revolution ...
