Anthropogenic increase of oceanic pCO2 in the Barents Sea surface water
Omar, Abdirahman M.; Johannessen, Truls; Kaltin, Staffan; Olsen, Are (Peer reviewed; Journal article, 2003-12-26)We evaluate the change of surface water CO2 partial pressure ( pCO2 sw) in the Barents Sea (BS) between 1967 and 2000–2001. We use temperature (T) data collected during a survey in the BS in 1967 and a relationship between ... -
Interannual variability in the wintertime air–sea flux of carbon dioxide in the northern North Atlantic, 1981–2001
Olsen, Are; Bellerby, Richard G. J.; Johannessen, Truls; Omar, Abdirahman M.; Skjelvan, Ingunn (Peer reviewed; Journal article, 2003)Gridded fields of sea surface temperature (SST), sea level pressure (SLP), and wind speed were used in combination with data for the atmospheric mole fraction of CO2 and an empirical relationship between measured values ... -
Reconstructing the time history of the air-sea CO2 disequilibrium and its rate of change in the eastern subpolar North Atlantic, 1972–1989
Omar, Abdirahman M.; Olsen, Are (Peer reviewed; Journal article, 2006)This study determines the temporal changes of wintertime surface ocean partial pressure of CO2 (pCO2 SW) in the eastern subpolar North Atlantic (esNA) (50–64ºN; 32–10ºW) by using data of carbon-system parameters and ...
