Dissolved inorganic carbon, total alkalinity, pH, nutrients and other variables collected from profile and discrete sample observations during NOAA Ship Gordon Gunter East Coast Ocean Acidification (ECOA-1) cruise GU-15-04 (EXPOCODE 33GG20150619) off the U.S. East Coast, North Atlantic Ocean from 2015-06-19 to 2015-07-23 (NCEI Accession 0159428)

This dataset contains dissolved inorganic carbon, total alkalinity, pH, nutrients and other variables collected from profile and discrete sample observations during NOAA Ship Gordon Gunter East Coast Ocean Acidification (ECOA-1) cruise GU-15-04 (EXPOCODE 33GG20150619) off the U.S. East Coast, North Atlantic Ocean from 2015-06-19 to 2015-07-23. 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.
