This dataset includes dissolved inorganic carbon (DIC), total alkalinity, partial pressure of CO2 (pCO2), pH on total scale, water temperature, salinity, dissolved oxygen concentration, nutrients, carbon-13 and other variables collected from discrete sample and profile observations during NOAA Ship Discoverer cruise EQ92_FALL (EXPOCODE 31DS19920906) in the Equatorial Pacific Ocean from 1992-09-06 to 1992-12-08. The instruments used to collect these data include alkalinity titrator, carbon dioxide (CO2) gas analyzer, coulometer for DIC measurement, CTD, Niskin bottles, and others. These data were collected by Rik Wanninkhof of NOAA Atlantic Oceanographic and Meteorological Laboratory (AOML) and Richard A. Feely of NOAA Pacific Marine Environmental Laboratory (PMEL) as part of the EQ92_FALL dataset. CDIAC associated the following cruise ID(s) with this dataset: EQ92_FALL
