The charts, maps and web sites consulted to determine the present-day depth contours used to characterize Pleistocene shore lines when sea levels were below present-day levels. The origin of the base maps presented here is a Geographic projection in ArcView (Environmental Systems Research Institute, Inc.) that is very similar to an Equal Area Cylindrical projection. The Geographic projection has minimal area distortion near the equator. Topography from WORLDBATH. This is the ETOPO5 5x5 minutes Navy database, giving bathymetry/ topography on a 5 minute by 5 minute grid. WORLDBATH data are taken from the National Geophysical Data Center (NGDC), under the National Oceanic and Atmospheric Administration (NOAA).
