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 depth and pH. The instruments used to collect these data include Spectrophotometer. 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:

Spectrophotometric pH measured at 25 degrees C using the total hydrogen ion scale

Dataset Description:
Spectrophotometric pH measured at 25 degrees C using the total hydrogen ion scale (pHT,25C). Data are reported from the POWOW1 (TN277), POWOW2 (KM1301), and POWOW3 (KM1312) cruises.

Supplemental Information
Acquisition Description:
pH was measured spectrophotometrically (Clayton and Byrne, 1993) in triplicate at standard temperature (25 degrees C) immediately following collection. pH samples were collected following recommended procedures (Dickson et al., 2007).
Purpose This dataset is available to the public for a wide variety of uses including scientific research and analysis.
