A new synthesis of seafloor topography from google earth allows us to see detailed views of deep ocean floor.
Atlantic imagery is available from both polar and geostationary satellites.
Explore worldwide satellite imagery and 3d buildings and terrain for hundreds of cities.
Sea floor geology is far simpler than the geology of the continents because erosion rates are lower and also because the continents have suffered multiple collisions associated with the opening and closing of ocean basins.

Such seafloor maps can aid submariners and ship captains with navigation particularly in previously uncharted areas.
Satellite imagery may also be used to map features in the water such as coral reefs.
It can be said that the satellite altimetry is unique among ocean remote sensing techniques because it provides us with much more information on the earth s gravitational field.

So instead of depending on sonar researchers looked to something else.
Methane seeps are areas where methane leaks from vast reservoirs deep in the ocean mud.
If that leak is big enough it provides an energy source for microbes who can capture it use it and pass it on to other organisms.
