File Description:

"88010051.a77" is the original data in NGDC format

"S04I_bathy_gdc.txt" is 88010051.a77 reformatted to our standard gdc format

"S04I_bathydist.txt" is the decimated bathymetry file, projected
    onto straight lines between station positions, used for plotting
    the vertical sections.

    Bathymetry was missing around station 1 and around station 64.  
    Therefore, Smith-Sandwell bathymetry data was used to fill in the missing areas.

"S04I_sta_bdep.txt" is the station list, with corrected bottom
    depths for each station, based on the WHP format station summary file
    s04isu.txt.
