Dataset Overview | National Centers for Environmental Information (NCEI)

Partial pressure of carbon dioxide, temperature, salinity and other variables collected from the surface underway observations using carbon dioxide gas analyzer, shower head equilibrator and other instruments from R/V Savannah in the North Atlantic Ocean, US East coast during the Georgia Coastal Ecosystems Long Term Ecological Research Cruises from 2014-04-02 to 2016-04-21 (NCEI Accession 0167308)

This dataset includes surface underway chemical, and physical data collected from R/V Savannah in the North Atlantic Ocean, US East coast from 2014-04-02 to 2016-04-21. These data include measurements of partial pressure of carbon dioxide (pCO2) in the equilibrator headspace (dry) at equilibrator temperature, barometric pressure in the equilibrator headspace, water temperature in equilibrator, sea surface temperature and sea surface salinity. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement. These data were collected by Wei-Jun Cai and Janet J. Reimer of University of Delaware as part of R/V Savannah Georgia Coastal Ecosystems Long Term Ecological Research Cruises.
