Dataset: Nutrients, targeted proteomics, and pigments from the METZYME cruise (KM1128)

This dataset includes data from 3 sampling systems:
- Macronutrients from the trace metal rosette (TMR); analyzed by Joe Jennings at OSU.
- Targeted metaproteomics from the McLane pumps; analyzed by triple quadrupole mass spectrometry calibrated with stable isotope labeled peptides.
- Pigments from a combination of CTD and TMR samples; determined by HPLC; analyzed by Jack DiTullio, University of Charleston. Note that pigments were collected by both CTD and TMR due to a loss of the CTD as station 2/3.

Samples were collected during the KM1128 METZYME research expedition (Metals and Enzymes in the Pacific) on the R/V Kilo Moana October 1-25, 2011 from Oahu, Hawaii to Apia, Samoa.

01 Aug 2017: dataset was revised to include columns for date/time and cast numbers for each sampling system.
