In 1957 the publication of heezen and tharp s physiographic map of the north atlantic was the first map of the seafloor that allowed the general public to begin to visualize the ocean floor.
Map of atlantic seafloor.
This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.
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.
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.

Each consist of three sheets a base bathymetric map.
The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.
This map shows the alvin dive track along the seafloor.
The map has more than twice the resolution of previous seafloor maps and shows a plethora of never before seen features.

The colors on this reflectivity map describe the hardness of the seafloor surface.
This product is intended to aid fishermen and those needing seafloor features and potential fishing grounds.
