Extreme Sea Level Changes

The following images were created from the ETOPO5 data set which has elevation data on grid spaced 5 arc minutes apart. Some areas have a lower resolution (the Amazon Basin for example). Land areas below sea level are colored as if they contain water. This is most noticeable for the Caspian Sea. Future upgrades will deal with this problem.

The following 3 images show the effects of changing sea level by the indicated amounts.
