Dissolved inorganic carbon (DIC), total alkalinity, partial pressure of CO2 (pCO2), pH on total scale, water temperature, salinity 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 (NCEI Accession 0000193)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 01:08 AM | Dataset Last Updated: February 21, 2017 at 12:00 AM
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
