These data include BAROMETRIC PRESSURE, Partial pressure (or fugacity) of carbon dioxide - atmosphere, Partial pressure (or fugacity) of carbon dioxide - water, SALINITY and SEA SURFACE TEMPERATURE. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer, Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement, not applicable and thermosalinographs. These data were collected by Akira Nakadate and Shu Saito of Japan Meteorological Agency (JMA) as part of the VOS_Ryofu_Maru_1995_1999 dataset. CDIAC associated the following cruise ID(s) with this dataset: 49UP19950716 This dataset is available to the public for a wide variety of uses including scientific research and analysis.
