Published on

Chris Pritchett
Professor, Physics and Astronomy,
University of Victoria

Presented at the Cybera/CANARIE National Summit 2009, as part of the session "Research Transformed by Cyberinfrastructure." This panel featured researchers who have seen their work transformed through cyberinfrastructure – ie. collaborations made possible, mountains of data rendered intelligible, remote instrumentation accessed.

  21. 21. Changing Sociology of Astronomy !! Science Teams 25 years ago: !! Individuals or groups of 2-3 people !! Allocations of a few nights of telescope time/year !! Small data collections for each project !! Science Teams Today: !! groups of dozens of people all over the world !! Allocations of 10%-30% of ALL telescope time is not uncommon !! Large data collections for each project !! Why the change? !! Better, more comprehensive science from large surveys 22
  22. 22. Canadian Astronomy Data Centre HST !! Delivers 2 Terabytes FUSE per week to users !! 2500 distinct users MOST !! 87 countries CFHT !! Serve all Canadian astronomy research Gemini universities !! Largest astronomy data BLAST centre in the world (by data volume) JCMT CGPS MACHO

  24. 24. Changing Role of CADC !! CADC 25 years ago: !! Archived data !! Made data accessible !! Today !! Design data management processes and systems in collaboration with observatories and Science Teams !! Implement and Operate these data management systems !! Why the change? !! Individual Science Teams cannot handle the processing and storage requirements for very large survey projects 25
