Dissolved inorganic carbon, total alkalinity, pH, Oxygen, and other variables collected from surface discrete observations using flow-through pump and other instruments in the East Coast of the U.S. and Canada during the 2nd East Coast Ocean Acidification (ECOA2, or ECOA-2) cruise from 2018-06-26 to 2018-07-28 (NCEI Accession 0196423)

This archival package contains the surface discrete measurements that were collected via the onboard flow-through system while the boat was moving and CTD casts were not taken during the East Coast Ocean Acidification (ECOA2) Cruise on board the R/V Henry Bigelow. The cruise started from Newport, took place in the Gulf of Maine and then along the East US coast to Miami. 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 14 transects approximately orthogonal to the Gulf of Maine and Atlantic coasts and a comprehensive set of underway measurements along the entire transect.
