This dataset contains the carbon chemistry measurements of a laboratory experiment study to understand the effects of ocean acidification on winter flounders. To address the goals of the NOAA Ocean Acidification Program (OA), the James J. Howard Laboratory constructed an OA experimental system to conduct OA experiments on commercially important species native to Atlantic waters of the NE U.S. The species of interest exhibit a broad range of ecological and life-history types from entirely marine to entirely estuarine. In order to conduct OA experiments on several different species, the required experimental system was able to mimic both estuarine and oceanic conditions. This system was designed to produce 5 pCO2 concentrations above an ambient pCO2 treatment and 5 temperature regimes. The system is also capable of manipulating dissolved oxygen, salinity, and other biogeochemicals common to a benthic habitat. The analytical laboratory conducts analysis according to the guidelines developed by the ocean acidification subcommittee of the Ocean Carbon and Biogeochemistry Program. When followed correctly, these guidelines should produce data with a high degree of accuracy and precision.

This dataset includes discrete sample and profile data collected in Whycocomagh Bay, Bras d’Or lakes from 2016-12-06 to 2017-12-05. These data include dissolved inorganic carbon (DIC), total alkalinity (TA), pH on total scale, partial pressure of CO2 (pCO2), hydrogen sulfide (H2S), methane (CH4), nutrients, dissolved oxygen, water temperature, salinity and other measurements. Deeper part of the region is anoxic and the provides an opportunity to study extreme marine redox chemistry.

This dataset includes continuous sea surface measurements of dissolved inorganic carbon (DIC), calculated total alkalinity, pH on NBS scale, calculated partial pressure of carbon dioxide (pCO2), temperature, salinity and dissolved oxygen during a small fishing boat cruises in Jiaozhou Bay, Yellow Sea, from 2018-04-25 to 2018-08-03. The data were collected using a Van Dorn water sampler aboard a small fishing vessel. At each station, just surface samples were collected since water column is vertically well mixed. The measurements were done under project named "Effects of biological processes on calcium carbonate saturation in eutrophic coastal oceans: a case study in Jiaozhou Bay", The project is funded by Basic Scientific Fund for National Public Research Institutes of China (2016Q01, 2019S05).

This dataset includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, pH on seawater scale, partial pressure of carbon dioxide (pCO2), dissolved organic carbon (DOC), chlorofluorocarbons (CFC-11, CFC-12), temperature, salinity, dissolved oxygen, nutrients, sulfur hexafluoride (SF6), delta C13 and delta C14 obtained during NOAA Ship Ronald H. Brown cruise CLIVAR_A16N_2013 (EXPOCODE 33RO20130803) in the Atlantic Ocean from 2013-08-03 to 2013-10-01. 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.

Seawater samples were collected in Chesapeake Bay for dissolved inorganic carbon (DIC) and total alkalinity (TA) from June 2016 to July 2018. They were collected in the lower half of the Bay aboard the R/V Fay Slover in collaboration with Old Dominion University's Chesapeake Bay Program Water Quality Laboratory and the VA Dept. of Environmental Quality. In the upper half of the Bay, samples were collected aboard the R/V Kerhin in collaboration with the Maryland Department of Natural Resources' Chesapeake Bay Water Quality Monitoring Program. Additional water quality parameters from the cruises were downloaded from the Chesapeake Bay program website. Additional carbonate system parameters were then computed from DIC and TA

This dataset includes discrete profile measurements of Dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, discrete pCO2, chlorofluorocarbons (CFC11, CFC12), dissolved organic carbon (DOC), water temperature, salinity, dissolved oxygen, nutrients and other hydrographic and chemical variables collected from discrete samples and profile observations during the R/V Thomas G. Thompson cruise on GO-SHIP repeat section A20 (EXPOCODE 325020210316) in the North Atlantic Ocean from 2021-03-16 to 2021-04-16. GO-SHIP repeat transoceanic surveys (www.goship.org) provide full water column hydrographic observations with temporal and spatial resolutions adequate to resolve decadal variability in oceanic storage of heat, freshwater, carbon, oxygen, nutrients and transient tracers. Repeat hydrographic physical-biogeochemical measurements nominally along 52° 20’N in the North Atlantic Ocean enables scientists to better tackle important unresolved aspects of the Atlantic Ocean’s response to decadal scale variability and increases in both heat and carbon dioxide as a result of anthropogenic activities. The U.S. GO-SHIP A20 2021 hydrographic section revisited this line for the fourth time, with prior transects occurring in 1997, 2003, and 2012.

The A22 2021 cruise aboard the UNOLS vessel R/V Thomas G. Thompson was undertaken as part of the US GO-SHIP (Global Ocean Ship-based Hydrographic Investigations Program), a major contributor to international GO-SHIP. The program’s overall objective is to collect quasi-decadal, highly accurate, surface-to-bottom, coast-to-coast, physical, and chemical oceanic observations. These measurements are essential to monitoring long-term changes in heat, freshwater, carbon, oxygen, and other tracers in the global ocean, the main reservoir in the Earth System.
