PACKAGE DESCRIPTION: This dataset includes partial pressure (or fugacity) of carbon dioxide, dissolved inorganic carbon (DIC), total alkalinity, water temperature, salinity, dissolved oxygen concentration, delta carbon-13, delta helium-3, helium, silicate, nitrate, nitrite, phosphate, radium isotopes, tritium and other variables collected from discrete sample and profile observations during R/V Knorr TTO-NAS cruises in the North Atlantic Ocean from 1981-04-01 to 1981-10-19. The instruments used to collect these data include CTD and Niskin bottles. These data were collected by Taro Takahashi of Columbia University; Lamont-Doherty Earth Observatory and Peter Brewer and R.T. Williams of University of California - San Diego; Scripps Institution of Oceanography as part of the TTO-NAS data set. CDIAC associated the following cruise ID(s) with this data set: TTO-NAS
