This dataset contains the surface discrete measurements of dissolved inorganic carbon, total alkalinity, pH and nutrients in the west coast of Florida near the Everglades National Park. Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry. Through the SOOP program we measure air and ocean surface pCO2 and take discrete samples of other carbon parameters. This effort is in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP).

This dataset contains discrete measurements of water temperature, salinity, total dissolved inorganic carbon (DIC), total titration alkalinity (TA), pH on total scale, and calcium concentration. These data were collected between April 2014 and April 2018 in Lavaca-Matagorda, Guadalupe-San Antonio, Nueces-Corpus Christi estuaries along the northwestern Gulf of Mexico.

This dataset consists of Discrete, profile measurements of dissolved inorganic carbon (DIC), total alkalinity (TA), pH on total scale, water temperature, salinity and other chemical and hydrographic parameters during the R/V W. T. Hogarth Coastal cruise H24062 (EXPOCODE 33SGDK20240302) in the U.S. East Coast and Gulf of Mexico from 2024-03-02 to 2024-03-08. Near-shore estuarine and coastal regions are where most recreational fishing and tourism occur, yet they are vastly under-sampled. Their susceptibility to OA is not well understood due to their high biogeochemical variability. These regions are affected by land-side processes such as river discharge and run-offs and ocean-side processes through slope water exchange. A full determination of the carbonate system in these regions in conjunction with open ocean measurements is needed to increase our understanding of the effects of OA on ocean health and fisheries and our ability to predict them. In this project, we propose to augment several observational campaigns by 1) adding a carbonate component to the harmful algal blooms (HABs) monitoring cruises conducted periodically on the Western Florida Shelf in order to study potential links between HABs and OA, 2) renewing our collaboration with select National Parks to complement and enhance our near-shore data collection on the Northern Gulf of Mexico and US East Coast, and 3) complementing our underway surface pCO2 measurements in the Gulf of Mexico and US East Coast with underway total alkalinity measurements to help us improve our fundamental understanding of nearshore OA processes. The addition of these measurements to the current assets already present in the region would enhance our understanding of the linkage between nearshore and open ocean processes and better assess the mechanisms and impacts of OA on the biogeochemistry, biology and their economic consequences.

Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry. Through the SOOP program we measure air and ocean surface pCO2 and take discrete samples of other carbon parameters.

This dataset includes chemical, discrete sample, physical and profile data collected from PIERRE RADISSON in the Baffin Bay and Davis Strait from 1999-08-27 to 1999-10-10 and retrieved during cruise CARINA/18RD19990827. These data include ALKALINITY, DISSOLVED INORGANIC CARBON, HYDROSTATIC PRESSURE, PARTICULATE ORGANIC CARBON, PARTICULATE ORGANIC NITROGEN, Potential temperature (theta), SALINITY, Total Organic Carbon (TOC) and WATER TEMPERATURE. The instruments used to collect these data include CTD and bottle. These data were collected by Humfrey Melling of Department of Fisheries and Oceans Canada, Lisa A. Miller of Department of Fisheries and Oceans; Institute of Ocean Sciences; Climate Chemistry Laboratory, Louis Fortier of Laval University, and Patricia L. Yager of UGA as part of the CARINA/18RD19990827 dataset. The CARINA (CARbon dioxide IN the Atlantic Ocean) data synthesis project is an international collaborative effort of the EU IP CARBOOCEAN, and U.S. partners. It has produced a merged internally consistent dataset of open ocean subsurface measurements for biogeochemical investigations, in particular, studies involving the carbon system. The original focus area was the North Atlantic Ocean, but over time the geographic extent expanded and CARINA now includes data from the entire Atlantic, the Arctic Ocean, and the Southern Ocean.

This dataset contains monthly-averaged surface fields of temperature, salinity, total alkalinity (TA), and dissolved inorganic carbon (DIC) derived from the GoMBio model for 1981-2014. GoMBio is a ROMS-based 8-km resolution ocean-biogeochemical model encompassing the entire Gulf of Mexico. Model details can be found in Gomez et al. (2018; https://doi.org/10.5194/bg-15-3561-2018) and Gomez et al. (2020; https://doi.org/10.5194/bg-17-1685-2020). We include the results of four model experiments: (1) model hindcast, (2) climatological Mississippi-Atchafalaya chemistry experiment (CLM_MC), (3) climatological river experiment (CLM_RIV), and (4) climatological forcing experiment (CLM_FORC). The model hindcast experiment was forced with surface fluxes of momentum, heat, and freshwater from the European Center for Medium Range Weather Forecast reanalysis product (ERA-Interim). We prescribed a time-evolving monthly series of freshwater discharge for 28 river sources in the U.S., and a climatological discharge for 10 rivers in the U.S. and 11 rivers in Mexico. We also prescribed time evolving concentration of nutrients, TA, and DIC for the Mississippi and Atchafalaya River System (MARS), and long-term climatological values for the other river sources. The CLM_MC and CLM_RIV experiments are like the model hindcast, but the river inputs were modified to evaluate the model sensitivity to changes in river runoff. In the CLM_MC experiment we used a monthly climatology for the MARS. In the CLM_RIV experiment we used climatological river discharge values for all rivers, as well as the climatological chemistry for the MARS. Finally, in the CLM_FORC experiment, we prescribed climatological patterns for rivers, surface fluxes and the open boundary conditions. The only exceptions were the atmospheric CO2 and the open boundary conditions for DIC, which varied as in the model hindcast. This last experiment was conducted to examine the influence of climate variability in ocean acidification patterns.
