Extracted chlorophyll data from CTD rosette bottles from R/V Thomas G. Thompson and R/V Kilo Moana cruises TN277, KM1301, KM1312 in the Eastern North Pacific Ocean from 2012-2013 (POWOW project) (NCEI Accession 0278616)
This dataset contains biological data collected on R/V Kilo Moana and R/V Thomas G. Thompson during cruises KM1301, KM1312, and TN277 in the North Pacific Ocean from 2012-03-01 to 2013-07-27. These data include chlorophyll a and depth. The instruments used to collect these data include Turner Designs Fluorometer -10-AU. These data were collected by Dr Zackary I. Johnson of Duke University as part of the "Seasonal and decadal changes in temperature drive Prochlorococcus ecotype distribution patterns (POWOW)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-03-05.
The following is the text of the dataset description provided by BCO-DMO:
Extracted chlorophyll data from CTD rosette bottles from 3 POWOW cruises.
Dataset Description:
Extracted chlorophyll concentrations from POWOW1 (TN277), POWOW2 (KM1301), and POWOW3 (KM1312) cruises. POWOW1 data include total chlorophyll (>0.22 um), >2 um, and >20 um. POWOW2 and POWOW3 data include total chlorophyll (>0.22 um) and >0.8 um.

Supplemental Information | Acquisition Description: Methods described in Johnson et al. 2010: Chlorophyll concentrations were measured by filtering 100 mL of seawater sample onto a polycarbonate filter (of pore size 0.22 um, 2 um or 20 um on POWOW1; and of pore size 0.22 um or 0.8 um on POWOW2) using gentle vacuum (<100 mm Hg) and extracting in 100% MeOH at -20 degrees C in the dark for >24 h following (Holm-Hansen and Riemann, 1978). Fluorescence was measured using a Turner Designs 10-AU fluorometer following Welschmeyer (1994) that was calibrated against a standard chlorophyll solution (Ritchie, 2006). |
