The under water topography maps have been developed by the study of ocean floor topography.
Diagram ocean floor topography map.
Typically finely wrought ocean maps have been the result of extensive sonar.
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 super detailed map of the ocean floor s topography is based on satellite measurements of subtle lumps on the ocean s surface.
Thanks to a new synthesis of seafloor topography released through google earth armchair explorers can now view five percent of the deep ocean floor in far greater detail than ever before.
This study is extensive and it has been established that the ocean floor has similar features of mountains and valleys as on the earth.
This is expensive and time consuming so sonar maps are mostly only made of places where ships spend the most time.
Researchers today published the most detailed map of the ocean floor ever produced.

All 1 250 000 and 1 1000 000 maps are overprinted with the minerals management service s ocs protraction diagram data.
Scientists used multibeam bathymetric data to create a 3 d view of a portion of the charleston bump.
The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.
Data collected by satellites and remote sensing instruments were used to created a model at least twice as.
Introductionin 2007 the california ocean protection council initiated the california seafloor mapping program csmp designed to create a comprehensive seafloor map of high resolution bathymetry marine benthic habitats and geology within the 3 nautical mile limit of california s state waters.
