Ocean floor map. Very little of the ocean floor has been mapped directly. The google earth data right is clearly higher resolution than that version of the scripps map left. It turns out that satellites can see below the sea surface.
Data collected by satellites and remote sensing instruments were used to created a model at least twice as. Topographic maps of the sea floor. We use a process that involves satellite imagery combined with a scientific diver s inspection of the sea bed called ground truthing to create extremely detailed maps that show the composition of the sea floor which can be made of sand rubble live coral or seagrass among other categories.

So how do we make maps of the global ocean floor.
The scripps sea floor map has also been used to discover a new microplate in the indian ocean. 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. The results that let this new marvelously detailed map of the seafloor from nasa s earth observatory be made were actually first published last year as part of a paper in science from researchers.
Detailed depth contours provide the size shape and distribution of underwater features. These habitat maps are entered into a gis so that they can be accessed by anyone with an internet connection. This super detailed map of the ocean floor s topography is based on satellite measurements of subtle lumps on the ocean s surface.
