The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Carbonate chemistry and CTD data collected along a North Pacific transect between Hawaii and Alaska on R/V Kilo Moana cruise KM1712 in August 2017 (NCEI Accession 0278666) |
| Abstract: | This dataset contains biological, chemical, optical, and physical data collected on R/V Kilo Moana during cruise KM1712 in the Gulf of Alaska and North Pacific Ocean from 2017-08-01 to 2017-08-31. These data include Aragonite Saturation State, density, depth, dissolved Oxygen, dissolved inorganic Carbon, fluorescence, pH, salinity calculated from CTD primary sensors, total alkalinity (TA), water pressure, and water temperature. The instruments used to collect these data include CTD profiler, Cavity enhanced absorption spectrometers, and Spectrophotometer. These data were collected by Jess F. Adkins and John D. Naviaux of California Institute of Technology, Xuewu Liu of University of South Florida, Nick E. Rollins, Sijia Dong, and William M. Berelson of University of Southern California, and Adam V. Subhas of Woods Hole Oceanographic Institution as part of the "Collaborative Research: CaCO3 Dissolution in the North Pacific Ocean: Comparison of Lab and Field Rates with Biogenic and Abiogenic Carbonates (CDISK_4)" and "Ocean Acidification - Collaborative Research: Measuring the kinetics of CaCO3 dissolution in seawater using novel isotope labeling, laboratory experiments, and in situ experiments (CaCO3 dissolution)" projects. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2021-01-20. The following is the text of the dataset description provided by BCO-DMO: Carbonate chemistry and CTD data along a North Pacific transect between Hawaii and Alaska Dataset Description: Acquisition Description: Water samples were collected at 24 different depths during each CTD cast. Temperature, salinity, [O2], density and fluorescence were measured in situ both downcast and upcast. After CTD recovery, water samples were collected and DIC, pH, d13C of DIC were measured onboard. Other parameters in the carbonate system were calculated using CO2SYS. DIC and d13C were measured using a Picarro Cavity Ring-Down Spectroscopy (G2131-i). pH was measured using a Varian Cary 400 spectrophotometer. The CTD included a rosette of 24 10L bottles. Data columns d13C_DIC_PDB_USC1 and d13C_DIC_PDB_USC2 were measured by the USC and Caltech groups. All other data columns to the right (d13C_DIC_PDB_USF1 and d13C_DIC_PDB_USF2, Alk, DIC, pH, OmegaCa, and OmegaAr) were measured by the USF group. |
