Brown: Explorer: Skogafoss: Ka'imimoana: Columbus Waikato: Palmer Gould NOAA pCO 2 on ships program Monitoring effort! (Be careful what you wish for) * 3 VOS in North Atlantic (Monthly-Weekly) (US-Iceland, US-Bermuda, Caribbean) * 3 Research ships in North Atlantic * 3 Data sites- 1 central QC - (Sent on the CDIAC -no data embargo)

NOAA pCO 2 on ships project FY-06 performance ≈ 483 K points

Carbo Ocean question: Will UK effort continue in near-term? New NOAA VOS line ?

Near real time data display

Instrumentation Status of GO ( General Oceanics) systems * 6-units in December, 6-units shortly (?)thereafter. Based on time of ordering * Initial product support assistance by Kevin Sullivan and Denis Pierrot, NOAA/AOML

First production run at GO Issue: Lack of tried and true old parts and subcomponents: LiCor, UIC coulometer

Approach (Lee et al. 1998, Park et al., 2006): pCO 2SWym =[pCO 2SW1995m + (  pCO 2SW /  SST) 1995m   SST ym  1995m ] Create seasonal (  pCO 2SW /  SST) relationships from Takahashi Climatology and apply it the interannual ocean temperature anomalies An initial global estimate of variability in air-sea fluxes

Results using a decade of remotely sensed SST and winds combined with (∂pCO 2SW /∂SST) relationships

Interannual changes ± 0.16 Pg C year -1 Other ocean (model) estimates are in this range as well Interannual variability  Most of the variability (≈70 %) attributed to the Eq. Pac. ENSO  50 % due the ∆pCO 2 anomalies; 50 % due to wind speed variability  Large regional changes- low global changes : regional compensating effects?

Closing thoughts on increased formal collaboration  Formal agreements on regional seasonal flux maps  Post-doc/ young investigator exchange funded by NSF/ EU?  Sponsored meetings for individual topics between US and EU? -Underway  Sponsored joint development of instruments, observing systems -Underway
