  This is an image generated from 2'x2' N/S surface deflections of the
vertical covering the Caribbean Sea and surrounding areas.  Some interesting 
features to note about this image are:

  The extensive E/W red feature (paralleled by a magenta feature) is the
effect of the Puerto Rico trench on the deflections of the vertical.  Some
of the largest geoid tilts in the world are found here, inducing large
deflections of the vertical as well.

  The edges of the trough and ridge systems running from Mexico toward 
Cuba and the Caribbean Sea can be distinguished as elongated, linear
features.

  The large red signal off the north shore of South America is due to the
extension of the Lesser Antilles islands along the coast.
