  1. Bristol Regional e-Science Centre:progress and plans Mark Birkinshaw University of Bristol

  2. Outline • BReSC and CeRB • BReSC theme: data-interactivity • BReSC progress • BReSC projects: some examples • WFS viewer: AstroGrid-2 • InSAR mapping • GENIE • Chemical structures Mark Birkinshaw, U. Bristol

  3. BReSC and CeRB Bristol: GridPP, GENIE, genomics, digital media, etc. UWE: Mammogrid Exeter: eStar, IAs Bristol: BReSC a component of CeRB Mark Birkinshaw, U. Bristol

  4. BReSC theme Data-interactivity: NRT DP using local Grid and display on AG node Cold and hot media – NRT manipulation and discovery Example: finding structure anomalies and features in multi-dimensional datasets via combination of display and calculation – astronomy, mathematics, … Mark Birkinshaw, U. Bristol

  5. BReSC progress AGN site preparation – decision for site was delayed, but now made, orders being placed eScience PDRA – offer made and informally accepted, will start in December (Bristol will hire a second PDRA) Internal Grid – under test, switches in place Science drivers – remain strong, additional University hires in area (Valdes et al.) SRIF spend – possible significant allocation being negotiated Mark Birkinshaw, U. Bristol

  6. Projects Some examples WFSviewer GENIE InSAR Isomerisation Others: Bristol: digital media, genomics, earthquake modelling, volcano predictions Exeter: eStar, Ias UWE: Mammogrid Mark Birkinshaw, U. Bristol

  7. Wide-Field Survey Viewer • Designed for a wide-field survey with multiple wavebands and camera positions • Source detection and merging of object catalogues • Uses overlaps and stellar colour-colour sequences to produce uniform photometry • Make, store true-colour images • Single interface to images & catalogues (local or remote) • Data analysis ‘plug-in’ modules Mark Birkinshaw, U. Bristol

  8. WFSV: data-analysis modules Slit-mask design: interactive slit edits, overlap checks Photometry plots: e.g. cluster colour-magnitude diagram Surface density plot: colour-magnitude selected samples Remote databases: e.g. FIRST catalogue, maps Mark Birkinshaw, U. Bristol

  9. GENIE? Grid ENabled Integrated Earth system model • Investigate long term changes to the Earth’s climate using g numerical models • e-Science aims: • Flexibly couple state-of-the-art components to form unified Earth System Model (ESM). • Execute resultant ESM on a Grid infrastructure. • Share resultant data produced by simulation runs. • Provide high-level open access to the system, creating and supporting virtual organisation of Earth System modellers. Mark Birkinshaw, U. Bristol

  10. The problem: Thermohaline circulation • Ocean transports heat through the “global conveyor belt.” • Heat transport controls global climate. • Wish to investigate strength of model ocean circulation as a function of two external parameters. • Use GENIE-Trainer. • Wish to perform 3131 = 961 individual simulations. • Each simulation takes 4 hours to execute on typical Intel P3/1GHz, 256MB RAM, machine 163 days Mark Birkinshaw, U. Bristol

  11. Scientific achievements Surface air temperature difference between extreme states (off - on) of the thermohaline circulation. North Atlantic 2C colder when the circulation is off. Intensity of the thermohaline circulation as a function of freshwater flux between Atlantic and Pacific oceans (DFWX), and mid-Atlantic and North Atlantic (DFWY). Mark Birkinshaw, U. Bristol

  12. Real science through real e-Science • Delivered Grid resources to perform simulations of prototype Earth System Model. • Delivered web based system to allow a virtual organisation of environmental scientists to create and manage simulations at a high-level. • Delivered database management system to allow scientists to share, access and visualise data produced by simulation runs. New results with profound implications: papers out! Mark Birkinshaw, U. Bristol

  13. Antarctic ice surface velocities: satellite InSAR Mark Birkinshaw, U. Bristol

  14. PE profile of isomerisation in NO + NH2 Mark Birkinshaw, U. Bristol
