   PI:              James J. McCarthy
   of:              Harvard University
   dataset:         Nitrogen-15 uptake rates for labeled
                    substrates of NO2, NO3 & NH4
   dates:           August 10, 1992 to September 14, 1992
   location:        N: 12.025  S: -11.9433  W: -140.7383  E: -134.935
   project/cruise:  EQPAC/TT011 - Fall Survey
   ship:            Thomas Thompson
 
   PI-Notes:
   Due to the strong diel patterns in nitrogen uptake and the resulting 
   possible misinterpretation of these profile data through simple integration
   and daily mulitpliers, the user community is directed to the areal summary
   data files and the Deep Sea Research paper (see McCarthy et al., in prep).
