Dissolved oxygen, temperature, salinity, and other variables measured from profile observations using CTD and other instruments from the Ronald H. Brown in the East Coast of the United States and Gulf of Mexico during the second Gulf of Mexico and East Coast Carbon (GOMECC-2) Cruise from July 24, 2

The second Gulf of Mexico and East Coast Carbon (GOMECC-2) Cruise on board the R/V Ronald H. Brown from Miami, took place in the Gulf of Mexico and then along the East US coast 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.
