Global Seafloor topography from Satellite Altimetry
Maps of seafloor elevation based on data collected by satellites. The satellite can't "see" the bottom of the ocean, instead it measures the elevation of the ocean and infers the shape of the seafloor. It seems like magic, but it's really science. See how cleverly it's done.

Site contains maps showing the distributions of tectonic plates over geologic time. Unlike other sites that only show changes in the position of the tectonic plates, the paleogeographic reconstructions here show changes in the distribution of oceans vs. land.

Free GIS Viewers from ESRI
ArcExplorer
"ArcExplorer is a lightweight GIS data viewer developed by ESRI. This freely available software offers an easy way to perform basic GIS functions. ArcExplorer is used for a variety of display, query, and data retrieval applications and supports a wide variety of standard data sources. It can be used on its own with local data sets or as a client to Internet data and map servers."
ArcReader
"ArcReader is a new addition to the ArcGIS Desktop family of products. It is a free, easy-to-use product that allows anyone to view, explore, and print published map files (PMFs). ArcReader was designed for viewing and sharing maps that access a wide variety of dynamic geographic data."

ArcExplorer Version 1.1 Import Utility
"An .e00 (E-zero-zero) file is an ArcInfo coverage converted into an ASCII text file intended for exchange between two ArcInfo systems on different platforms. They are not intended for compression, but they have become popular as exchange files. To convert an .e00 file to an ArcInfo coverage, download the ArcExplorer 1.1 Import Utility. The Import Utility works with ArcExplorer 2 as well."
