   PI:              James McCarthy
   of:              Harvard University
   dataset:         Ammonium Concentrations
   dates:           February 07, 1992 to March 09, 1992
   location:        N: 9.0658  S: -12.1113  W: -140.511  E: -135
   project/cruise:  EQPAC/TT007 - Spring Survey
   ship:            Thomas Thompson
 
   PI-Notes:
   Samples were obtained with the *trace metal-clean* rosette and
   assayed by the method of Brzezinski (1988) Limnol. & Oceanog. 33:
   1176-1182. Detection limit = 0.002 micro molar.
