Ocean Topography
 
Looking for something that shows ocean depth/feet in detail?

I've been looking for this kind of info/imagery as well. Didn't come up with much. The bathymetry option from buskid's link shows some, but not much.

I once worked for a business that scanned the seafloor and collected that x/y/z (depth) data for the bay and other local areas and it is very expensive to do.

Take a look here for stuff http://www.google.com/search?hl=en&r...w=1045&bih=528

First you need something to accurately collected depth information and time stamp that information.
Then you need a heave compensator that measures the boat's pitch, yaw and roll and time stamp that information.
Then you need a GPS device that has sub-meter accuracy and time stamp the location information.
Now take all that info and process it - meaning the angle of the beam that goes 'straight' down needs to have geometrical calculations applied due to the yaw, pitch, roll of the boat to calculate a new position and depth.

This is needed if you want detail. Please share if you find something with detail.
