Walton Smith cruise WS20231 (EXPOCODE 33WA20200818) in the Southeast U.S. Shelf, Gulf of Mexico from 2020-08-18 to 2020-08-22 (NCEI Accession 0231440)",
    "description": "This dataset contains 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 WS20231 (EXPOCODE 33WA20200818) in the Southeast U.S. Shelf, Gulf of Mexico from 2020-08-18 to 2020-08-22.\n\nIncreasing 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.",
