This NCEI Accession consists of discrete measurements of dissolved inorganic carbon (DIC), total alkalinity (TA), pH, dissolved oxygen, water temperature, salinity sampled in the National Park Service coastal sites along the Gulf Region and East Coast of the United States from 2024-07-02 to 2024-09-16. The NOAA Atlantic Oceanographic and Meteorological Laboratory (AOML) through a collaboration with the National Park Service collected ocean acidification discrete samples at select National Parks along the East Coast of the US and in the Gulf Region to increase near-shore data collection on a bi-annual frequency. Whenever possible, sample collection is coordinated with the OAP-funded GOMECC and ECOA cruises.

This dataset consists of dissolved inorganic carbon, total alkalinity, water temperature and salinity from laboratory analyzed discrete water samples taken at the Central Gulf of Mexico Ocean Observing System buoy moored at 28.9N, 90.5W off Coastal Louisiana from 2017-07-14 to 2022-02-20. These are validation samples for the NOAA Pacific Marine Environmental Laboratory (PMEL) Moored Autonomous pCO2 (MAPCO2®) system buoy CoastalLA_91W_30N, that includes SeaBird CTD and SAMI pH instruments.

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.

Dissolved Inorganic Carbon (DIC) and Total Alkalinity (TA) samples collected via Niskin bottle and analysed on shore from the Gulf of California in the summers of 2004, 2005, and 2008, as well as from the Eastern Tropical North Pacific in 2008. These data were collected by Fredrick Prahl of OSU and Brian Popp of UHM as part of the Paleo Perspectives on Climate Change and Biological Oceanography projects, and submitted by Matthew Wolowe of OSU.

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 contains discrete bottle sample data collected from the Gray's Reef mooring, within the Gray's Reef National Marine Sanctuary in February. Samples were collected from the surface layer, treated with 0.1 µL of HgCl2, stored on ice, and transported to the University of Delaware for DIC and TAlk analysis. Data is used to calculate pCO2 and compared to moored observations for internal consistency and validation of time series observations.
