Dissolved inorganic carbon, total alkalinity, nutrients, and other variables collected from CTD profile, discrete bottle, and surface underway observations using CTD, Niskin bottle, flow-through pump, and other instruments from NOAA Ship Ronald H. Brown in the Gulf of Mexico, Southeastern coast of the United States, and Mexican and Cuban coasts during the third Gulf of Mexico and East Coast Carbon (GOMECC-3) Cruise from 2017-07-18 to 2017-08-20 (NCEI Accession 0188978)

This dataset contains data collected from the coastal waters of the Gulf of Mexico, including US, Mexican and Cuban waters during the third Gulf of Mexico Ecosystems and Carbon Cruise (GOMECC-3) on board NOAA Ship Ronald H. Brown. The expedition started and returned from Miami, FL in the summer of 2017. 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 third occupation, with the first occurring in 2007, and the second in 2012, and complemented mooring time series and other regional OA activities. The cruise included a series of 11 transects approximately orthogonal to the Gulf of Mexico and Atlantic coasts and a comprehensive set of underway measurements along the entire transect.
