This dataset contains carbon and nutrient related data that were collected from CTD profile measurements in the Northeast coast of the United States (EXPOCODE: 316G20120202, CRUISE ID: DE1202). 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. Studies have demonstrated adverse effects on calcifying organisms, particularly some invertebrates, corals, sea urchins, pteropods, and coccolithophores. This effort is in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP).

This dataset contains dissolved inorganic carbon, total alkalinity, pH on total scale, nutrients and other variables measured from profile discrete observations during NOAA Ship Gordon Gunter cruise GU1804 (EXPOCODE 33GG20180822) in the North Atlantic Ocean, Gulf of Maine, Georges Bank, and Mid-Atlantic Bight from 2018-08-22 to 2018-08-31. 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.

This dataset includes discrete profile measurements of Dissolved inorganic carbon (DIC), total alkalinity, pH on sea water scale, dissolved organic carbon (DOC), chlorofluorocarbons (CFC-11, CFC-12), temperature, salinity, oxygen, nutrients, and other variables measured during NOAA Ship Ronald H. Brown cruise along the Global Ocean Ship-Based Hydrographic Investigation Program (GO-SHIP) Section I07N (EXPOCODE 33RO20180423) in the Indian Ocean on from 2018-04-23 to 2018-06-06. Hydrographic measurements were carried out along the I07N section in the western Indian Ocean in April-June 2018 under the auspices of GO-SHIP. The unique aspect of the 2018 I07N research cruise is that it was the first reoccupation of the I07N section since 1995. The section was not revisited for about 23 years because of the rise of piracy in the region.

This dataset contains surface discrete measurements of dissolved inorganic carbon, total alkalinity, water temperature, salinity and other variables collected from surface discrete observations using flow through pump, CTD, Niskin Bottles and other instruments during NOAA Ship Ronald H.

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.

The effort was in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP). The cruise was designed to obtain a snapshot of key carbon, physical, and biogeochemical parameters as they relate to ocean acidification (OA) in the coastal realm. The cruise included a series of 11 transects approximately orthogonal to the Gulf of Maine and Atlantic coasts and a comprehensive set of underway measurements along the entire transect.
