This dataset contains discrete underway measurements collected on the transit from Cape Verde, to Miami, FL during the NOAA Ship Ronald H. Brown cruise RB2201 (EXPOCODE 33RO20220107) in the North Atlantic Ocean from 2022-01-07 to 2022-01-23. There are 47 discrete underway stations collected via a continuously flowing underway line fed from a seawater intake located at the bow, approximately 5 meters below the waterline. Parameters include water temperature, salinity, DIC, TA, and pH.

This dataset contains discrete underway and surface (above 10dbar) CTD bottle measurements collected during the NOAA Ship Ronald H. Brown Global Ocean Ship-Based Hydrographic Investigations Program (GO-SHIP) sections A13.5, A12 cruises in the North and South Atlantic Ocean from 2020-02-21 to 2020-04-17. There were 8 surface CTD measurements collected from Niskin Bottles and 330 discrete underway samples collected via a continuously flowing underway line. Discrete underway data has typically not been reported and the purpose of this dataset is to collate unpublished and published surface measurements together from the same research cruise in a usable format. Parameters include water pressure, water temperature, salinity, dissolved oxygen, DIC, TA, pH (SWS), pCO2, silicate, nitrite, nitrate and phosphate.

This dataset includes discrete profile measurements of Dissolved inorganic carbon (DIC), total alkalinity, pH on sea water scale, dissolved organic carbon (DOC), chlorofluorocarbons (CFC-11, CFC-12), temperature, salinity, oxygen, nutrients, and other variables measured during NOAA Ship Ronald H. Brown cruise along the Global Ocean Ship-Based Hydrographic Investigation Program (GO-SHIP) Section I07N (EXPOCODE 33RO20180423) in the Indian Ocean on from 2018-04-23 to 2018-06-06. Hydrographic measurements were carried out along the I07N section in the western Indian Ocean in April-June 2018 under the auspices of GO-SHIP. The unique aspect of the 2018 I07N research cruise is that it was the first reoccupation of the I07N section since 1995. The section was not revisited for about 23 years because of the rise of piracy in the region.

This dataset includes discrete and profile observation data collected from NOAA Ship Ronald H. Brown in the Pacific Ocean from 2015-04-10 to 2015-06-27. These data include water temperature, salinity, nutrients, chlorofluorocarbons (CFC-11, CFC-12), sulfur hexafluoride (SF6), dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, dissolved organic carbon (DOC), tritium, helium, delta C14, and delta C13. The International GO-SHIP Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.

This dataset contains dissolved inorganic carbon, total alkalinity, pH on total scale, nutrients and other variables measured from profile discrete observations during NOAA Ship Gordon Gunter cruise GU1902 (EXPOCODE 33GG20190815) in the North Atlantic Ocean, Gulf of Maine, Georges Bank, and Mid-Atlantic Bight from 2019-08-15 to 2019-08-30. Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry ultimately resulting in a reduction in pH, a process termed ocean acidification. Studies have demonstrated adverse effects on calcifying organisms, particularly some invertebrates, corals, sea urchins, pteropods, and coccolithophores, but also on species of commercial interest such as oysters or crabs. In support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP), the Ecosystem Monitoring Cruises (ECOMON) are utilized to collect water samples to measure water column inorganic carbon and hydrographic parameters including nutrients. Samples are collected at three depths (surface, mid-depth and near bottom) at select stations on a quarterly basis in the northeastern Atlantic continental shelf region off the United States. Water samples were sent to and analyzed by scientists at the Atlantic Oceanographic and Meteorological Laboratory (AOML) for dissolved inorganic carbon, pH and total alkalinity concentrations. Additional samples are analyzed for nutrient concentrations at the University of Maine. These data are used to monitor short-long term coastal ocean acidification trends.
