Discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH on total scale and other hydrographic and chemical parameters obtained during R/V Nathaniel B. Palmer Repeat Hydrography and SOCCOM Cruise NBP18_02 in the Pacific Sector of Southern Ocean: GO-SHIP Section S04P (EXPOCODE 320620180309), from 2018-03-09 to 2018-05-14 (NCEI Accession 0225497)

This dataset includes discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH (on total scale), water temperature, salinity, dissolved oxygen, nitrate, nitrite, silicate, phosphate, chlorofluorocarbons and other chemical measurements during the R/V Nathaniel B. Palmer Repeat Hydrography and SOCCOM Cruise NBP18_02 in the Pacific Sector of Southern Ocean: GO-SHIP Section S04P (EXPOCODE 320620180309), from 2018-03-09 - 2018-05-14. The Pacific Ocean S04P repeat hydrographic line was reoccupied for the US Global Ocean Carbon and Repeat Hydrography Program. The survey of S04P 2018 consisted of CTDO, rosette, LADCP, UVP, water samples and underway measurements. The ship departed from the port of Hobart on the island of Tasmania, Australia and completed the cruise in the port of Punta Arenas, Chile.
