Enhancing Oceanic Carbon Observations: FUTURE Project Updates and Initiatives

The FUTURE project continues to expand its observational network, focusing on critical oceanic carbon measurements. Key initiatives include the VOS line from France to Brazil, new ship deployments in the UK-Caribbean, and a replacement buoy in Minas. Additional atmospheric measurements will be gathered in Greenland and Weybourne. The project also aims to synthesize mechanistic understanding of pCO2 variability through various in situ and remote sensing methods, while evaluating the observing system and its implications for estimating North Atlantic carbon sinks.

Presentation Transcript

  1. FUTURE WP4 • Observations: continue existing network • New measurements: • VOS line France-Brazil • New ship on UK-Caribbean • Replacement buoy: MINAS • New sensor in Western Eq Atlantic PIRATA mooring • New atmospheric measurements: Greenland, Weybourne

  2. FUTURE WP5 • Continue to monitor fCO2 on ship lines and with carioca drifters • 2 more drifters will be deployed March 2008 in the Western Atlantic • Synthesis: • Mechanistic understanding of the relevant processes controlling observed and modeled pCO2 variability in association with in situ (e.g. ARGO mixed layer depth) and/or remote sensing measurements (ice cover, altimetry, sea surface temperature, ocean color, wind speed). • Link between high DIC close to SAF and formation of Subantarctic Mode Water (SAMW) in Winter

  3. Decadal trends:Why different trends between Indian and Western Pacific Ocean ? (Metzl, 2007 sub.)

  4. From decadal to inter-decadal trends of pCO2 A challenge for pCO2 synthesis and modelling pCO2 trends from ORCA LIM-PISCES model 1990-2001 1970s 1980s 1960s Lenton et al.

  5. Future WP 6 • NA observing system synthesis: • Estimate NA sink 2005, 2006, 2007 with uncertainties • Reproduce/evaluate observing system strategy in model • Implications for atmospheric inversion estimates. • Paper on observing system and 2005 data to be submitted during 2008. • Neural network technique evaluation • Accuracy? • Use for inter-annual variability • Evaluate with model output? • Application of techniques to other areas (N Pacific? Southern Ocean? • Assimilation of CO2 data into Ocean BGCM (Hadley centre) • Direct assimilation of pCO2 data (AWI)
