Dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, and other hydrographic and chemical data obtained during the SOCCOM float deployment expedition onboard R/V Investigator cruise IN2016_V03 along the GO-SHIP section P15S (EXPOCODE 096U20160426) from 2016-04-26 to 2016-06-30 (NCEI Accession 0168141)
PACKAGE DESCRIPTION: This dataset includes discrete bottle measurements of dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, temperature, salinity, oxygen, nutrients, delta C14, delta C14, helium and other chemical parameters collected during the SOCCOM float deployment expedition onboard R/V Investigator cruise IN2016_V03 along the GO-SHIP section P15S (EXPOCODE 096U20160426) from 2016-04-26 to 2016-06-30. The R/V Investigator cruise IN2016_V03 is the part of the SOCCOM project cruise from the research ships in the South Pacific Ocean and Southern Ocean. These data are part of the World Data Service for Oceanography and US State Department Marine Research U2015-032.
