 Sampling Methodology

 NOTE:           The Arabian Sea samples were preserved with 0.33% 
                paraformaldehyde vs. ~1% for EQPAC.  Flow cytometry counts 
                were corrected based on counting efficiencies of beads vs. 
                E. coli for EQPAC.

 PI-Note:  An incorrect volume was used for event 08282130 in the original data.
           The corrected data (version January 11, 1999) reflect this
           calculation correction.
