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

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, …

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 placeScience drivers – remain strong, additional University
hires in area (Valdes et al.)SRIF spend – possible significant allocation being
negotiated

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
6 November 2003 Mark Birkinshaw, U. Bristol 8
NeSC, Nov 2003
Slit-mask design: interactive slit edits, overlap checks
Photometry plots: e.g. cluster colour-magnitude diagram
Remote databases: e.g. FIRST catalogue, maps
Surface density plot: colour-magnitude selected samples
WFSV: data-analysis modules

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.

NeSC, Nov 2003
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 3131 = 961 individual simulations. Each simulation takes 4 hours to execute on typical Intel P3/1GHz,
256MB RAM, machine 163 days

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

NeSC, Nov 2003
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!
