   PI:              Cindy Lee
   of:              State University of New York at Stony Brook
   dataset:         Amino Acid compositions from plankton tow collections
   dates:           August 5, 1992 to September 18, 1992
   location:        N: -12.0  S: 12.0  W: -140.0  E: -140.0
   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.

Instruments

High-Performance Liquid Chromatograph

Supplied Name: High Performance Liquid Chromatography

Supplied Description:

Fluorescence high performance liquid chromatography (HPLC) was used to measure particulate amino acids.

Instrument Type

Generic Name: High-Performance Liquid Chromatograph

Acronym: HPLC

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB11/

Generic Description:

A High-performance liquid chromatograph (HPLC) is a type of liquid chromatography used to separate compounds that are dissolved in solution. HPLC instruments consist of a reservoir of the mobile phase, a pump, an injector, a separation column, and a detector. Compounds are separated by high pressure pumping of the sample mixture onto a column packed with microspheres coated with the stationary phase. The different components in the mixture pass through the column at different rates due to differences in their partitioning behavior between the mobile liquid phase and the stationary phase.
