Total alkalinity, pH (on total scale) and other hydrographic and chemical data obtained during the R/V S.A. Agulhas II SOCCOM cruise AGU027 (EXPOCODE 91AH20170907) in the South Atlantic Ocean from 2017-09-07 to 2017-10-11 (NCEI Accession 0170849)
PACKAGE DESCRIPTION: This dataset includes profile discrete measurements of total alkalinity, pH (on total scale), temperature, salinity, oxygen, nutrients and POC obtained during the R/V S.A. Agulhas II SOCCOM cruise AGU027 (EXPOCODE 91AH20170907) in the South Atlantic Ocean from 2017-09-07 to 2017-10-11. The R/V Agulhas II cruise AGAU027 was the Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) biogeochemical profiling float deployments cruise.
