This dataset includes biological, chemical, discrete sample, physical and profile data collected from NOAA Ship MALCOLM BALDRIGE in the North Pacific Ocean and South Pacific Ocean from 1992-02-24 to 1992-05-19. These data include CHLOROPHYLL A, DELTA CARBON-13, DELTA CARBON-14, DISSOLVED INORGANIC CARBON (DIC), DISSOLVED OXYGEN, Delta Oxygen-18, HYDROSTATIC PRESSURE, NITRATE, NITRITE, PHAEOPHYTIN, Partial pressure (or fugacity) of carbon dioxide - water, Potential temperature (theta), SALINITY, TOTAL ALKALINITY (TA), WATER TEMPERATURE, pH, phosphate and silicate. The instruments used to collect these data include Alkalinity titrator, CTD, Coulometer for DIC measurement, Flask with closed headspace for discrete carbon dioxide (CO2) measurement, bottle and spectrophotometer. 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_SPRING dataset. CDIAC associated the following cruise ID(s) with this dataset: EQ92_SPRING
