browse graphicPreview graphic
This NCEI Accession includes surface underway, chemical, meteorological and physical data collected from NOAA Ship Ronald H. Brown in the Atlantic, Pacific and Indian Oceans in 2018. These data include air-sea difference of partial pressure of carbon dioxide (pCO2), barometric pressure, pCO2 in atmosphere, pCO2 in water, salinity and sea surface temperature. The instruments used to collect these data include CO2 gas analyzer and shower head chamber equilibrator for autonomous CO2 measurement. These data were collected by Rik Wanninkhof, Denis Pierrot and Kevin Sullivan of US DOC; NOAA; OAR; Atlantic Oceanographic and Meteorological Laboratory as part of the SOOP (Ship of Opportunity Program) NOAA ship Ronald Brown 2018 cruises data set.
