The ASTEX directory mage/oceanus data supplied by Byron Blomquist of 
Drexel University.  The data was collected from the ship Oceanus for 
the ASTEX experiment in the AZORES during the month of June, 1992.

Measurements of sulfur in the ocean are in ocnswdms.txt.  Sulfur
in the air is in ocnsulf.txt.  And meteorologic ship data is 
compiled in ocnsmet_tar.Z, which is obviously compressed and tarred.
The files *.cat describe the data.
