Brown GO-SHIP Section A16S_2013 cruise RB1307 (EXPOCODE 33RO20131223) in the South Atlantic Ocean, from 2013-12-23 to 2014-02-04.

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.

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 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 seawater analyses conducted during the fourth Gulf of Mexico Ecosystems and Carbon Cycle (GOMECC-4) cruise on board the NOAA Ship Ronald H. Brown departing from Key West, FL into the Gulf of Mexico and then around the coastal waters of the Gulf of Mexico in a counter-clockwise direction. Samples were collected using a CTD-O2 rosette equipped with 24 niskin-style bottles. The cruise took place from September 13–October 21, 2021 and ended in St. Petersburg, FL. The effort was in support of the coastal monitoring and research objectives of NOAA’S Ocean Acidification Program. The expedition was designed to obtain a snapshot of key carbon, physical, and biogeochemical parameters as they relate to ocean acidification (OA) in the coastal realm. This was the fourth occupation of the Gulf of Mexico as part of the Ocean Acidification Program’s monitoring efforts, with the first three occurring in 2007, 2012 and 2017. The cruise included a series of 15 transects approximately orthogonal to the coast of the Gulf of Mexico and a 16th partial transect along the 27°N line between Florida and the Bahamas. On the transit between each of these transects, discrete samples were collected from the underway seawater line to obtain a comprehensive set of underway measurements.

This dataset includes discrete sample and profile data collected during a NOAA Ship Ronald H. Brown cruise along the CLIVAR Repeat Hydrography Section A10 (EXPOCODE 33RO20110926) in the South Atlantic Ocean from 2011-09-26 to 2011-10-31. These data include measurements of dissolved inorganic carbon (DIC), pH on SWS, total alkalinity, chlorofluorocarbons (CFC-11, CFC-12), sulfur hexafluoride (SF6), dissolved organic carbon (DOC), total dissolved nitrogen (TDN), delta carbon 14, delta carbon 13, temperature, salinity, dissolved oxygen, silicate, nitrate, nitrite, phosphate, carbon tetrachloride and theta. The instruments used to collect these data include Alkalinity titrator, CTD, coulometer for DIC measurement, Niskin bottles and pH sensors. The International CLIVAR Global Ocean Carbon and Repeat Hydrography 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 includes dissolved inorganic carbon, total alkalinity, water temperature, salinity, chlorofluorocarbons (CFCs), carbon-13 and other variables collected from discrete sample and profile observations during NOAA Ship Malcolm Baldrige cruise CGC_90 (EXPOCODE 33MW19900222) in the Pacific and Southern Oceans from 1990-02-22 to 1990-04-16. The instruments used to collect these data include CTD, Coulometer for DIC measurement and bottle. These data were collected by David P. Wisegarver, Marilyn F. Lamb, and Richard A. Feely of NOAA Pacific Marine Environmental Laboratory (PMEL) as part of the CARINA_CGC_90 and CGC-90_32MW19900222 dataset. CDIAC associated the following cruise ID(s) with this dataset: 3175CG90_1 and CGC_90. The World Ocean Circulation Experiment (WOCE) was a major component of the World Climate Research Program with the overall goal of better understanding the ocean's role in climate and climatic changes resulting from both natural and anthropogenic causes. The CO2 survey took advantage of the sampling opportunities provided by the WOCE Hydrographic Program (WHP) cruises during this period between 1990 and 1998. The final collection covers approximately 23,000 stations from 94 WOCE cruises.

This data package contains Underway total alkalinity, water temperature, salinity and other variables collected from surface seawater during the NOAA Ship Ronald H. Brown 2021 West Coast Ocean Acidification cruise RBWCOA2021 (EXPOCODE 33RO20210613) in the North Pacific Ocean from 2021-06-14 to 2021-07-20. Data were collected from the ship's underway seawater supply during the NOAA Ocean Acidification Program-funded West Coast Ocean Acidification (WCOA) cruise. This underway TA effort was part of the NOAA Ocean Acidification Program (OAP) grant entitled "Expanding near-shore carbonate measurements along the East-coast and Gulf of Mexico through multiple collaborations". Along with total alkalinity, corresponding temperature and salinity measurements are included. Measurements of pCO2 taken on these cruises are available from NOAA's AOML.

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.
