In Praise of Google Earth Oceans

You may find it useful that Google Earth's updated ocean topography includes, perhaps unintentionally, an ability to "fly" underwater, providing an unusual perspective of oceanic terrain features that may be applicable to various studies. The accuracy and detail depend upon the location chosen, as with surface views.

For the adventurous it is possible to "fly" at 1000 knots along the bottom of, or loop in the Puerto Rican Trench, but the slower aircraft program should permit even the faint-hearted a chance to see their area of interest at a more leisurely pace. The normal mouse commands are sufficient to control the "flight" with a little practice, although guidance from any teenage lab assistant with gaming experience may be useful. There is no penalty for "crashing".

Open Google Earth (4.3 and later). Position over a location such as Monterey Bay or some area with prominent canyon features. Drop to 1<2000m,>
