File Description:

"I01_botdepth.txt" is the original data file.
    Obtained November 1998 from P. Robbins.
    It was a merge of 5 minute readings from the PDR and the underway GPS data.
    It does not include depths for the last set of 5 stations.  Bathymetry from 
    Smith-Sandwell altimetric data set was used for the missing portion.

"I01_bathydist.txt" is the decimated bathymetry file, projected
    onto straight lines between station positions, used for plotting
    the vertical sections.

"I01_sta_bdep.txt" is the station list, with corrected bottom
    depths for each station, based on the WHP format station summmary files
    I01esu.txt and I01wsu.txt.
