European Union integrated project no Variation in atmosphere-ocean fluxes of CO 2 in the Atlantic Ocean: first results from the Carbo-Ocean observing system in the North Atlantic Andrew Watson School of Environmental Sciences University of East Anglia On behalf of Core theme 1 of Carbo-Ocean Thanks to Truls Johannesen, Are Olsen, Abdiraman Omar Arne Krtzinger, Tobias Steinhoff Ute Schuster, Maciek Telzewski Jon Olafsson Antoine Corbire, Nicolas Metzl, Nathalie Lefvre Aida Rios, Fiz Perez, Martina Alvarez Nick Bates Heike Lger, Rik Wanninkhof and many others Annual flux of CO 2 across the sea surface a climatology for 2000 from Takahashi et al (2006) in preparation [mol m -2 year -1 ] The worlds oceans conveyor belt from Sabine et al (2004) Science 305: Total ANTHROPOGENIC CO 2 in the oceans by 1994 [mol CO 2 m -2 ] The Carbo-ocean North Atlantic observing system The first co-ordinated, operational multi-ship voluntary observing network for sea surface pCO 2 and air-sea flux. Currently 5 commercial ships of opportunity and one research vessel. Co-ordinated with US and Canadian observing efforts. Aims: an accurate assessment of air-sea flux at seasonal-or-better time resolution, ~ 75,000, Plants: Soil & detritus: 1, Total land: 2, Total ocean: 38,400 Anthropogenic 6.3 The changes between the UK and the Caribbean from Schuster and Watson (2006) JGR, in review monthly sea surface pCO 2 annual air-to-sea flux from Sabine et al (2004) Science 305: 367 371, supplement Anthropogenic CO 2 in the different ocean basins Column inventory [mol m -2 ] 0o0o 80 o S40 o S40 o N Latitude from Sabine et al (2004) Science 305: 367 371, supplement Anthropogenic CO 2 in the different ocean basins Latitudinal inventory [mol m -2 ] 0o0o 80 o S40 o S40 o N Latitude Total laitudinal inventory [Pg C] o0o 80 o S40 o S40 o N Latitude
