Ocean Fluxes in CarbonTracker Andy Jacobson, Taro Takahashi, Colm Sweeney, David Ho, Roger Dargaville, and Rik Wanninkhof Andy Jacobson, Wouter Peters, Colm Sweeney, and the CarbonTracker Team Ocean Carbon Cycle Developments Ocean inversions New Takahashi climatology Gas exchange developments Southern Hemisphere anecdote

Ocean inversions give significantly different fluxes than ∆pCO 2 climatology

Takahashi et al. (2007) - New ∆pCO 2 Climatology Annual mean flux is PgC/yr Referenced to 2000 instead of 1995
