Marie tharp july 30 1920 august 23 2006 was an american geologist and oceanographic cartographer who in partnership with bruce heezen created the first scientific map of the atlantic ocean floor tharp s work revealed the detailed topography and multi dimensional geographical landscape of the ocean bottom. But in the 1950s and 60s when this feat of cartography was being assembled by us cartographers marie tharp and bruce heezen we knew almost nothing. These early maps based on hundreds of thousands of hand picked depths provided the context for the plate tectonics revolution. 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.

We ve come a long way in ocean exploration since the days of the hms challenger launched in 1858. Seafloor mapping also called seabed imaging is the measurement of water depth of a given body of water bathymetric measurements are conducted with various methods from sonar and lidar techniques to buoys and satellite altimetry various methods have advantages and disadvantages and the specific method used depends upon the scale of the area under study financial means desired measurement. Today we know more about the topography of the moon and mars than we do about our own planet s sea floor. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.
