ASCII bathymetry file from L. Talley. 

Expocode: 31TTTPS47
Chief Scientist: Lynne Talley
Ship:  R/V Thomas G. Thompson
Ports: Hakodate, Japan to Seattle, Washington 
Dates: 4 Aug 1985 - 7 Sep 1985
-------------------------
"P01_botdepth.txt" is the original data file, with depths every 5
minutes from the PDR record.  Positions were also entered by hand and
are not as accurate as more modern data sets.

"p01_bathy_gdc.dat": is in Geological Data Center
    format and includes corrected depths.  2000.10.17 (updated)

"p01_bathydist.dat" is the decimated bathymetry file, projected
    onto straight lines between station positions, used for plotting
    the vertical sections.

"p01_sta_bdep.dat" is the station list, with corrected bottom
    depths as taken from the p01su.txt file (station summary file)

"p01_sta_bpres.dat" is the station list, with corrected bottom
    pressures for each station, based on the p01su.txt file
    (station summary file)

--------------------------
