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.
