Mark Birkinshaw, U. Bristol

Bresc and cerb
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

Bresc theme
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

Bresc progress
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


Some examples






Bristol: digital media, genomics, earthquake modelling, volcano predictions

Exeter: eStar, Ias

UWE: Mammogrid

Wide field survey viewer
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

Wfsv data analysis modules
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

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

The problem thermohaline circulation
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

Scientific achievements
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).

Real science through real e science
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!
