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: | Biogeochemical data collected during the Flower Garden Banks Rapid Response Cruise, FGB-RR16, on R/V Manta in the Flower Garden Banks National Marine Sanctuary from July to August 2016 (NCEI Accession 0278828) |
| Abstract: | This dataset contains chemical and physical data collected on R/V Manta during cruise FGB-RR16 in the Gulf of Mexico from 2016-07-31 to 2016-08-01. These data include Ammonium, Aragonite Saturation State, Nitrate, Nitrite, density, depth, dissolved Oxygen, dissolved inorganic Carbon, pH, reactive phosphorus (PO4), salinity calculated from CTD primary sensors, total alkalinity, and water temperature. The instruments used to collect these data include CTD Sea-Bird 25, MARIANDA VINDTA 3C total inorganic carbon and titration alkalinity analyser, Niskin bottle, Nutrient Autoanalyzer, and Winkler Oxygen Titrator. These data were collected by Kathryn E.F. Shamberger of Texas A&M University as part of the "RAPID: Collaborative Research: Impact of freshwater runoff from Hurricane Harvey on coral reef benthic organisms and associated microbial communities (Rapid Reefs Harvey)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-02-06. The following is the text of the dataset description provided by BCO-DMO: Biogeochemical data collected during the Flower Garden Banks Rapid Response Cruise Dataset Description: This dataset combines the biogeochemical data collected during the Flower Garden Banks Rapid Response Cruise which occurred following the discovery of the localized mortality event. |

| Supplementary information: | Acquisition Description: The CTD (SBE-25) was equipped with 6 4L niskin bottles and was used to measure temperature and salinity. Niskins were used to collect water samples for carbonate chemistry (i.e., DIC and TA), oxygen, and nutrients. Water samples for DIC and TA were collected according to the methods in Dickson et al. (2007), and analyzed at TAMU using a VINDTA 3C. Certified Reference Materials (CRMs) were provided by A. Dickson at Scripps Institute of Oceanography (Dickson et al. 2007) and were used to calibrate for TA and DIC. The reproducibility of these samples was 1.43 ± 1.07 μmol kg-1 for TA and 2.64 ± 1.24 μmol kg-1 for DIC. Dissolved oxygen (DO) was measured using Winkler titrations. After collecting the water from the Niskin into flasks, aliquots of manganese chloride and sodium hydroxide-sodium iodide were added. The titration was performed directly after water collection using sodium thiosulfate; Winkler titration was performed with an amperometric dead-stop endpoint determination with a double platinum electrode. Nutrient samples (nitrate, nitrite, ammonium, phosphate, and silicate) were collected into polycarbonate flasks after filtration through GF/C 0.7-um pore size filters, frozen, and analyzed ashore using standard World Ocean Circulation Experiment (WOCE) segmented flow methodologies using an Astoria Analyzer (Astoria-Pacific) (Gordon 1994 ). Sampling gaps are reported as "nd" in the dataset. |
