Dissolved inorganic carbon, total alkalinity, nutrients, and other variables collected from profile and discrete observations during NOAA Ship Henry B. Bigelow cruise HB1902 (EXPOCODE 33HH20190522) in Gulf of Maine, Georges Bank, and Mid-Atlantic Bight from 2019-05-22 to 2019-06-06 (NCEI Accession 0209045) |
| Abstract: |
This dataset contains profile discrete measurements of dissolved inorganic carbon, total alkalinity, pH on total scale, temperature, salinity, nutrients, and oxygen collected during NOAA Ship Henry B. Bigelow cruise HB1902 (EXPOCODE 33HH20190522) in Gulf of Maine, Georges Bank, and Mid-Atlantic Bight from 2019-05-22 to 2019-06-06. Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry ultimately resulting in a reduction in pH, a process termed ocean acidification. Studies have demonstrated adverse effects on calcifying organisms, particularly some invertebrates, corals, sea urchins, pteropods, and coccolithophores, but also on species of commercial interest such as oysters or crabs. In support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP), the Ecosystem Monitoring Cruises (ECOMON) are utilized to collect water samples to measure water column inorganic carbon and hydrographic parameters including nutrients. Samples are collected at three depths (surface, mid-depth and near bottom) at select stations on a quarterly basis in the northeastern Atlantic continental shelf region off the United States. Water samples are sent to and analyzed by scientists at the Atlantic Oceanographic and Meteorological Laboratory (AOML) for dissolved inorganic carbon, pH and total alkalinity concentrations. Additional samples are analyzed for nutrient concentrations at the University of Maine. These data are used to monitor short-long term coastal ocean acidification trends. |
