 Modification history:  YYMMDD
    090317:  latitude and longitude values changed to negative
             to indicate West and South
 
 DMO note: During the EqPac and Arabian Sea sampling programs, the preferred
           units for pigment data were micrograms/m2/day.  The preferred 
	   unit of measurement in September 2002 is picomol/m2/day.
