Exploring Ocean Tectonics from Space

Google Earth’s 3D view of the Ocean floor was first introduced in version 5. It has been improved a number of times since then. Panaromio photos in the oceans were added in 2010 and underwater Street View in 2012.

Google’s current ocean floor data comes from a number of sources, including:

  • Ship bathymetry data. Learn more about it in this post.
  • An extrapolation of water surface heights to estimate undersea mountains and canyons, based on radar data collected by satellite.
  • Satellite data on slight variations of the pull of gravity over the oceans.

One of the organizations that has provided this data in the past is the Scripps Institution Of Oceanography, University of California, San Diego. Yesterday, they released some new data from the satellites CryoSat-2 and Jason-1, including global maps of the sea floor that they have released in KML format so they can be viewed in Google Earth. Read more about it and download the KMLs here. Be sure to watch the video featured on that page, which explains more about it.

  1. not that amazing

  2. Hi Mickey

    From cancel 3d upload models to 3dwh, everything has become very sad and boring

    I decided to cancel my subscription to your blog interesting. I do not want to receive notifications of things that never will use more than 3 seconds, view and close.

    This blog has been a great reference when Google allow, insert models into Google Earth, but now makes no sense to continue this type of publication ..

    has been very useful, but now it is not for me ..

    a greeting

    sorry for my bad English .. well actually translates google .. which is not very accurate
