Topographic Map Ocean Floor. The USGS conducts high-resolution mapping to describe the physical features of the ocean floor, as well as the geologic layers and structure beneath it. 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

National Ocean Service (NOS) Office of Coast Survey U.S Undertaken by the Seafloor Mapping Lab of California State University, Monterey Bay over a span of 44 days, the study involved 1,138.
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 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. The SWOT satellite (Surface Water and Ocean Topography), launched into orbit in 2022 and the result of the collaboration between NASA and the French National Center for Space Studies (CNES), allowed you to get a new one very detailed map of the ocean floor.This was possible thanks to its particularly advanced technology, which overcomes the limits of previous satellites dedicated to ocean.
. Yet cartographers still searched for ways to include information about the ocean in their maps. National Ocean Service (NOS) Office of Coast Survey U.S
18.1 The Topography of the Sea Floor Physical Geology. The following features are shown at example depths to scale, though each feature has a considerable range at which it may occur: continental shelf (300 feet), continental slope (300-10,000 feet), abyssal plain (>10,000 feet), abyssal hill (3,000 feet up from the abyssal plain), seamount (6,000 feet. However, less than 10% of the seafloor has been mapped globally
