Topographic Map Ocean Floor

Topographic Map Ocean Floor. For most of history, what lay below the sea surface and on the seafloor was a mystery Researchers have built a detailed map of the ocean floor's topography by using satellites to spot subtle, watery lumps on the ocean's surface

This graphic shows several ocean floor features on a scale from 0-35,000 feet below sea level Yet cartographers still searched for ways to include information about the ocean in their maps.

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 For most of human history, maps were hand-drawn and considered quite artistic Ocean Basemap The Ocean Basemap includes bathymetry, surface and subsurface feature names, and derived depths
