WP11 Model performance assessment and initial fields for scenarios.
Objectives and deliverables
To determine, how well biogeochemical ocean general circulation models (BOGCMs) are able to reproduce
carbon cycle observations from the real world with respect to temporal and spatial distributions
To refine criteria for model performance with respect to observations and other models
To establish a quality check for the initial conditions for future scenarios with BOGCMs
D11.3 (Version 2) Quality assessment of present day BOGCM simulations in form of written summary. This
deliverable is delivered but will be extended to include further Earth system models. (Extended to month 30 as
revised version). Done (Bergen).
D11.9 Extended data sets 1985-2009 monthly data sets as for Schneider et al. (2007), repeat analysis for
pCO2, Cant (month42)
D11.6 Extended comparison between model and observations and consistency check with other model
approaches.
Breakdown into regions (data synthesis regions, comparison with inverse analyses). Addition of CFCs and
natural 14C (natural) for off-line model circulations. Addition of analysis of nutrient and oxygen fields. (Month
36).
Done: Schneider et paper, LSCE looks at Southern Ocean and N.Atl., CFCs have been done by Laurent,
nutrient and oxygen plots, North Atlantic/Irminger Sea done by Bergen.
D 11.7 Atmospheric pCO2 comparison model/observations. (Month 42)
Partially done/under way.
D 11.8 Analysis of the decadal variability in the ocean biogeochemical models and of the comparability
model/observations for DIC, O2, nutrients, and further carbon cycle tracers. (Month 42) (extended to month 48
to include more data).
Partially done: forced models. (MPI under way, Bergen already done in first version, could be repeated)
Partially done: full ESMs, detailed variability on O2 (Bern)
To be done: Comparability (binning of pCO2 before comparison, Bergen).
WP17. Coupled climate carbon cycle simulations.
Objectives and deliverables
To provide standard set ups of coupled carbon-climate models including simulations for the present
To provide predictions of ocean carbon sources and sinks with the standard model configurations for a
standard emission scenario 2000-2200
To determine important feedback processes – key regional areas in the response of oceanic carbon cycle to
climate change
To provide interfaces for the new feedback processes as investigated under WP 16 and core theme 4
D 17.5 Carbon cycle data sets for basic future scenarios 2000-2100 from Hadley and Bergen Models (month 48) (partner 1and
33) - simulation running for Hadley, components ready for Bergen
D 17.8 Further simulations & analysis on the 2100-2200 period with IPSL and Bern Models [a. 0 emission after 2100 and b. 2100
emissions after 2100] (month 36) (Partner 6 and 11)
- simulations done or almost done by Bern and IPSL.
- analysis in the coming 6 months
D 17.9 Publication on intercomparison of oceanic carbon uptake on the 1860-2100 period, including others C4MIP models
(month 36) (Partner 6 and all)
- draft soon to be circulated to the group
- possibly one more model (Hadley) in the coming 2 months
D 17.10 Analysis of climate change impact on export production of POC, CaCO3 and potential feedback on carbon uptake
(month 42) (Partner 11, 6 and 13).
- on track
D17.11 Effects of other greenhouse gases (CH4, N2O, CFC, …) and anthropogenic aerosols on ocean carbon uptake and
climate-carbon feedback (at least one group) (month 48) (Partner 6)
D17.12 Meeting of WP16 and WP17 to discuss current results and new coupled models runs, including feedback processes
investigated under WP16 (month 48) (all).
WP18. Feasibility study on purposeful carbon storage.
Objectives and deliverables
To determine the kinetics and phase-transfer reactions between liquid CO2, hydrate, and seawater from
laboratory experiments under high pressures.
To simulate the near-range dispersion of injected CO2 using these new kinetic constraints and improved
meso-scale models for CO2 injection in the deep ocean and at the sea floor
To prepare the simulation of the large-scale propagation of injected CO2 and the global ocean’s retention
efficiency (using these improved near-range constraints and a global high-resolution model)
D18.3 Extended parameters for near-range geochemical kinetics and
phase transfer for deep ocean storage (month 42)
D18.5 Global scale high resolution modelling of CO2 release (month
42).
D18.6 Comparison of the observations of condensed CO2 behaviour
from laboratory and field observations (54)
