This dataset contains physical data collected on R/V Thomas G. Thompson during cruise TN303 in the South Pacific Ocean from 2013-10-29 to 2013-12-18. These data include depth and water pressure. The instruments used to collect these data include CTD Sea-Bird SBE 911plus and Niskin bottle. These data were collected by Gregory Cutter of Old Dominion University, Karen L. Casciotti of Stanford University, James H. Swift of University of California-San Diego, Mark A. Brzezinski of University of California-Santa Barbara, James W. Moffett of University of Southern California, and Christopher R. German and William J. Jenkins of Woods Hole Oceanographic Institution as part of the "GEOTRACES Peru-Tahiti Nitrogen Isotope Measurements (EPZT Nitrogen Isotopes)", "Measurement of Helium Isotopes, Tritium, Noble Gases, and Radiocarbon (EPZT Noble Gases He Tritium)", and "U.S. GEOTRACES East Pacific Zonal Transect (U.S. GEOTRACES EPZT)" projects and "U.S. GEOTRACES (U.S. GEOTRACES)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2023-01-23.

Supplemental Information
Acquisition Description:
We use the Optimum Multiparameter Analysis (OMPA) method to determine water mass percentages along the GP16 transect. This involves the use of hydrographic measurements from GP16 (temperature, salinity, oxygen, and nutrients), which can be found in a separate BCO-DMO dataset (see CTD - ODF Bottle ). For samples having potential density anomalies greater than 27 kg m-3, the OMPA was conducted according to the procedure outlined by Tomczak (1981), Tomczak and Large (1989), and others. For samples in the thermocline, defined as those samples having densities between 26 and 27, we use the 'thermocline array' method to determine the water mass fractions, according to the procedure outlined by Jenkins et al. (2015). Samples having densities less than 26 kg m-3 were not included in the water mass analysis. The uncertainty in water mass percentage is calculated using a Monte Carlo routine, where the defined properties of each water mass are varied to encompass the reported range of properties in that water mass. Lastly, the signal to noise ratio is calculated by dividing the percentage of given water mass in a each sample by the uncertainty of that water mass.
Purpose This dataset is available to the public for a wide variety of uses including scientific research and analysis.
