 PI:              Cindy Lee
 of:              State University of New York at Stony Brook
 dataset:         Amino Acid compositions from plankton tow collections
 project/cruise:  EqPac/TT011, Fall survey
 ship:            R/V Thomas Thompson

 Methodology:
 Lee, C; Wakeham,S.G.; Hedges, J.I., 2000.  Composition and flux of particulate
 amino acids and chloropigments in equatorial Pacific seawater and sediments.
 Deep-Sea Research, I, 47 (8), 1535-1568.
 
 PI Notes:

 We did not weight the plankton, so have nothing to calculate a concentration.
 We only interpret the compositions, and do not talk about concentration except
 relative to organic carbon measured in the same samples.
 
 The plankton net tows were oblique tows from 0-100m.  In most cases
 the samples analyzed are composites of two or more tows. As a result,
 no event numbers are reported.
 
 Station name "Rhiz" is a plankton tow made across a Rhizosolenia castracanei 
 patch near 2N, 140W.
