Ammonium (NH4) 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 0277413)
This dataset contains chemical 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 Ammonium and depth. The instruments used to collect these data include Niskin bottle. 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 2023-01-23.
The following is the text of the dataset description provided by BCO-DMO:
Ammonium (NH4) data from CTD rosette bottles from 3 POWOW cruises.
Dataset Description:
Ammonium (NH4) concentration in nM from 3 POWOW cruises (TN277, KM1301, and KM1312). Samples that had a mean concentration (mean of replicated samples) below the nominal detection limit are reported as zero.

Supplemental Information | Acquisition Description: Ammonium was measured on fresh, unfiltered samples following Holmes et al. 1999. Certified reference materials were used to verify protocols (Inorganic Ventures: QCP-NT, QCP-NUT-1, CGSI1-1). The detection limits of NH4 were: 9 nM for POWOW1 samples 5 nM for POWOW2 and POWOW3 samples |
Purpose | This dataset is available to the public for a wide variety of uses including scientific research and analysis. |
