This time series dataset includes weekly and bi-weekly discrete seawater samples of pH and total alkalinity, dissolved inorganic carbon, phosphates and profile measurements of temperature and salinity from 2009 to 2021. These are used to track the dynamics and controls on local carbon chemistry at the southwest part of Puerto Rico in support of the ocean acidification and water quality research in regional coastal and near-shore zones. Some of these environmental parameters have been monitored since 2009 when the National Oceanic and Atmospheric Administration (NOAA) Coral Health and Monitoring Program established the Atlantic Ocean Acidification Test-Bed (AOAT) at the Marine Reserve of La Parguera, Puerto Rico. As a key part of this project, a moored autonomous pCO2 system (MAPCO2) was deployed along the fore-reef of Enrique shelf reef and a discrete sampling at the Marine Reserve for data validation and calibration commenced. This monitoring effort supports the requirements of the recent implementation of La Parguera as a Class III climate and ecosystem monitoring station through the National Coral Reef Monitoring Program (NCRMP) in support of the NOAA Coral Reef Conservation Program (CRCP) and the Ocean Acidification Program (OAP).

This dataset includes measurements of dissolved inorganic carbon (DIC), total alkalinity (TALK), pH, phosphates and profile measurements of temperature and salinity in the southwest coast of Puerto Rico from 2009 to 2019. These data are used to track the dynamics and controls on local carbon chemistry at the southwest part of Puerto Rico in support of ocean acidification and water quality research in regional coastal areas.

This dataset contains profile discrete measurements of dissolved inorganic carbon, total alkalinity, pH on total scale, water temperature, salinity and other variables collected from profile discrete observations using flow through pump, CTD, Niskin Bottles and other instruments during the F.G. Walton Smith CIOERT2017 cruise WS17135 (EXPOCODE 33WA20170515), in the Gulf of Mexico, Caribbean Sea and North Atlantic Ocean from 2017-05-15 to 2017-06-13. 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) and the Climate Program Office.

This dataset contains the surface discrete measurements of dissolved inorganic carbon, total alkalinity, pH on total scale and nutrients during the R/V Savannah cruise SAV1803 (EXPOCODE 33H620180308) in the west coast of Florida, Gulf of Mexico from 2018-03-08 to 2018-03-13. Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry resulting in a reduction in pH, a process termed ocean acidification. In support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP), the South Florida Project Cruises (SFP) are utilized to collect water samples to measure surface water inorganic carbon and hydrographic parameters including nutrients. Samples are collected from seven stations on a bi-monthly basis to monitor the outflow of the Shark River Slough (SRS) into the southwestern Gulf of Mexico. Water samples are sent to and analyzed by scientists at the Atlantic Oceanographic and Meteorological Laboratory (AOML) for dissolved inorganic carbon, pH, total alkalinity and nutrient concentrations. These data are used to observe the effects of the SRS on acidification in the coastal ocean.

G. Walton Smith cruise WS22281 (EXPOCODE 33WA20221008) in the Southeast U.S. Shelf, Gulf of Mexico from 2022-10-08 to 2022-10-14. 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.
