The NOAA Atlantic Oceanographic and Meteorological Laboratory (AOML) through a collaboration with the National Park Service collected ocean acidification discreet samples at select National Parks sites along the East Coast of the United States and in the Gulf of Mexico 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 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 H23314 (EXPOCODE 33SGDK20231110) in the U.S. East Coast and Gulf of Mexico from 2023-11-10 to 2023-11-18. 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.

This dataset contains validation samples for moored time-series observations of ocean acidification water chemistry. This dataset includes temperature and salinity data from CTD sensors and dissolved inorganic carbon concentration, total alkalinity, and nutrient data from Niskin bottle samples collected at the same times and places. Samples were collected on eight cruises conducted between May 2011 and October 2014 on various vessels to service the Chá Bă ocean acidification mooring off La Push, Washington. This dataset is a subset of a larger dataset of observations collected from Washington coastal waters, in the Strait of Juan de Fuca, and within Puget Sound that will be submitted to NCEI in the future. The larger dataset spans the time window of February 2008 to October 2014.

This dataset contains the discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH on total scale, ammonia, water temperature, salinity, dissolved oxygen and nutrients during the R/V F. G. Walton Smith cruise WS20279 (EXPOCODE 33WA20201005) in the Southeast U.S. Shelf, Gulf of Mexico from 2020-10-05 to 2020-10-12. 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 34 stations on a bi-monthly basis to monitor the outflow of the Shark River Slough (SRS) and red tide in 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.

This dataset includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, water temperature, salinity, dissolved oxygen, phosphate, silicate, nitrate, nitrite, dissolved organic carbon (DOC), chlorofluorocarbons (CFC-11, CFC-12) and other measurements collected during the R/V Pelagia GEOTRACES cruise PE321 (EXPOCODE 64PE20100611) in the North and Tropical Atlantic Ocean from 2010-06-11 to 2010-07-08.

This dataset consists of discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity (TA), water temperature, salinity, nutrients and dissolved oxygen during the CCGS Vector Water Properties Survey cruise 2015-17 (EXPOCODE 18VT20150401) in the Strait of Georgia, Juan de Fuca Strait of the North American Pacific coast from 2015-04-01 to 2015-04-05. The samples were taken from rosette casts with 10L Niskin bottles and analyzed at the Institute of Ocean Sciences. Discrete samples of dissolved oxygen were also collected and analyzed onboard the vessel. CTD profiles were recorded with each rosette cast. DIC and TA samples were placed in cold storage for 5-6 weeks before analysis. A total of 76 DIC and TA pairs were sampled with a 17% replication rate; and the pooled standard deviations (of difference between replicate pairs) were calculated to be 0.9 µmol/kg and 2 µmol/kg respectively. The Strait of Georgia Water Properties Survey is a regular sampling program of 3 - 4 cruises per year; and additional data from cruises under this program will be submitted in the future.
