Columnar Tables

This is an inefficient format, so be warned: you are going to get a HUGE datafile.

The NOAA NGDC ETOPO1 ice surface elevation/bathymetry data are available as a columnar table, i.e. as multiple columns of data, intended primarily to be read. However, if you have other intentions for this table, or simply do not like the default choices, you may want to choose from the columnar tables with options.
