CLIVAR and Carbon Potential for Collaboration

CLIVAR and Carbon - Potential for Collaboration

• Katy Hill Howard Cattle
• International CLIVAR Project Office
• Southampton Oceanography Centre
• University of Southampton, UK

2
CLIVAR - primary objective

• To describe and understand the physical processes
  responsible for climate variability and
  predictability on seasonal, interannual, decadal,
  and centennial time-scales, through the
  collection and analysis of observations and the
  development and application of models of the
  coupled climate system, in cooperation with other
  relevant climate-research and observing
  programmes.

CLIVAR requirements for hydrographic resurvey

• CLIVAR has identified the need for a reoccupation
  of a subset of the hydrographic sections that
  formed the WHP to
• Refine WOCE determinations of oceanic heat
  freshwater transports
• Document decadal and shorter period ocean changes
• Provide monitoring of variability and change in
  the ocean
• Provide data for model validation and
  initialisation

4
CLIVAR - carbon context

• JSC/WCRP mandate for CLIVAR to take up the
  objective of understanding the role of the ocean
  in climate and long term ocean variability
  post-WOCE
• Role of CLIVAR in the IGBP-IHDP-WCRP Joint
  Global Carbon Cycle Project
• Increasing need for climate models to represent
  the carbon cycle for prediction of climate
  variability and change

5
WOCE/JGOFS Ocean Transport Workshop follow-up

• The WOCE/JGOFS Ocean Transport Workshop made a
  strong recommendation for collaboration among the
  CLIVAR and international carbon communities, in
  particular in the context of repeat WOCE
  sections.
• Follow-up meeting at the IGBP Open Science
  Conference
• As a result
• ICPO established a Web Page on which to post
  details of planned (and past) occupation of
  sections for hydrography carbon.
• Need for an ad hoc panel identified (status?)

CLIVAR/Carbon collaboration opportunities

• Through CLIVARs Ocean Basin Panels (each of
  which is identifying/has identified an ocean
  carbon representative) and through the CLIVAR
  OOP, in providing scientific focus
• Encouraging submission of information to a
  Carbon/Hydrographic Section Web page (currently
  on line on the CLIVAR Home Pages).
• Through ICPO assistance with joint meetings,
  workshops etc.
• By helping to provide the physical context for
  ocean carbon measurements
• By actively exploring cross cutting issues
  between CLIVAR and the ocean carbon community
  (for example in relation to anthropogenic climate
  change)

CLIVAR/carbon - issues

• How do we best coordinate the inventory of repeat
  hydrography/carbon hydrographic sections and what
  is the best home for this?
• WOCE set stringent standards for data through the
  WHP Manual. This may need revision/updating -
  how is this best achieved and by whom?
• CLIVAR is giving attention to repeat
  hydrography/carbon but little to near surface CO2
  activities as yet (issue for CLIVAR)
• How do the carbon ocean observation activities
  (this workshop, the wider ocean
  biogeochemistry/IGBP oceans activity, the
  IGBP-IHDP-WCRP Global Carbon Project and the
  needs of e.g the IPCC modelling community fit
  together?
