This dataset contains dissolved inorganic carbon, Total alkalinity, pH on Total Scale, nutrients and other variables measured from profile discrete measurement in the Northeast coast of the US in 2017. 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 & 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 contains the discrete (Niskin bottle and CTD profile) data collected near the UNH/PMEL CO2 Buoy, located off the coast of New Hampshire, between 2016 and 2020. All data were collected aboard the UNH R/V Gulf Challenger. Additionally, an underway pCO2 measurement system was operated on these cruises, and surface underway pCO2 data are included in this archival package.

This dataset contains discrete measurements of dissolved inorganic carbon, total alkalinity, pH, dissolved oxygen, and nutrients collected at the buoy off the coast of New Hampshire in the years 2011-2015. University of New Hampshire, in conjunction with NOAA's Pacific Marine Environmental Laboratory, has been operating a buoy off the coast of New Hampshire since 2006.

This dataset contains the surface discrete measurements of dissolved inorganic carbon, total alkalinity, pH on total scale and nutrients during the R/V F. G. Walton Smith cruise WS18120 (EXPOCODE 33WA20180430) in the west coast of Florida, Gulf of Mexico from 2018-04-30 to 2018-05-03. 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 seven stations on a bi-monthly basis to monitor the outflow of the Shark River Slough (SRS) into 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.

CDIAC associated the following cruise ID(s) with this dataset: CLIVAR_AR07W_2013 The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters. The World Ocean Circulation Experiment (WOCE) was a major component of the World Climate Research Program with the overall goal of better understanding the ocean's role in climate and climatic changes resulting from both natural and anthropogenic causes. The CO2 survey took advantage of the sampling opportunities provided by the WOCE Hydrographic Program (WHP) cruises during this period between 1990 and 1998. The final collection covers approximately 23,000 stations from 94 WOCE cruises.
