Dissolved inorganic carbon, total alkalinity, pH, fugacity of carbon dioxide, and other variables from surface observations using Niskin bottle, flow through pump and other instruments from NOAA Ship Ronald H. Brown in the Gulf of Mexico and East Coast of the United States during the second Gulf of Mexico and East Coast Carbon (GOMECC-2) Cruise from 2012-07-22 to 2012-08-13 (NCEI Accession 0117971)

This dataset contains ocean acidification related data from the second Gulf of Mexico and East Coast Carbon (GOMECC-2) Cruise on board NOAA Ship Ronald H. Brown. The cruise left from Miami, made measurements in the Gulf of Mexico, and continued collecting observations along the East US coast as it transited from the Gulf of Mexico to Boston. 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. This was the second occupation, with the first occurring in 2007, and complemented mooring time series and other regional OA activities. The cruise included a series of 8 transects approximately orthogonal to the Gulf of Mexico and Atlantic coasts and a comprehensive set of underway measurements along the entire transect.
