Deployment-specific acquisition description

   PI:              James J. McCarthy
   of:              Harvard University
   dataset:         N-15 uptake rates, profile data, for
                    substrates of NO2, NO3, NH4
   dates:           January 09, 1995 to January 31, 1995
   location:        N: 22.4835  S: 9.9986  W: 57.2999  E: 68.7499
   project/cruise:  Arabian Sea/TTN-043 - Process Cruise 1 (Late NE Monsoon)
   ship:            Thomas Thompson
 
   Note from PI dated 6/30/97:
   Profile uptake rates contain computational corrections
   in several places (June 1997).
 
   Samples were obtained with the trace metal-clean rosette
 
   Documentation Revised 09/10/1999:
 
   Methodology:  McCarthy, J.J., C. Garside, and J.L. Nevins. (1999) Nitrogen
   Dynamics during the Arabian Sea Northeast Monsoon. Deep-Sea
   Research II 46 (1999) 1623-1664.
 
   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 also reported for this cruise.
