        abstract:  This dataset consists of the surface measurements of temperature, salinity and pH on the total scale. An automated underway pH system was operated in the hydro lab of NOAA Ship Ronald H. Brown during the CLIVAR/GO-SHIP cruise on the Repeat Section A13.5_2010 (EXPOCODE 33RO20100308) in the North Atlantic Ocean and South Atlantic Ocean from from 2010-03-08 to 2010-04-17.
        purpose:  Mapping surface pH during the CLIVAR-GO-SHIP Repeat Section A13.5 cruise
