Topographic Map Ocean Floor

Topographic Map Ocean Floor. The seafloor has distinct features and characteristics that help us better understand Earth's current and past conditions, potential resources, and natural hazards Topographic maps of the sea floor, produced at a 1:100,000 scale that contain Loran-C rates, bottom sediment types and known bottom obstructions

Ocean Basemap 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. This graphic shows several ocean floor features on a scale from 0-35,000 feet below sea level
