Description

The scientific community is facing an exponential increase of the data generated by the state of the art instruments and the Square Kilometre Array (SKA) will be an exemplar in this context. This radio telescope, with the potential to provide revolutionary science in Astrophysics, Physics and Astrobiology, will be the greatest data research public project, once complete. It will be composed of thousands of antennas distributed over distances of up to 3000 km, on both Africa and Australia and it will generate a copious data flux (around 1TB/s) that will turn the task of extracting scientifically relevant information into a scientific and technological Big Data challenge. The SKA Science Data Processor (SDP), will transform this flux of raw data into calibrated data products at an average rate of about 150PB/year. An Alliance of SKA Regional Centres (SRCs) is being designed to address the challenge of scientifically exploiting the SKA data deluge. This alliance will provide astronomers with access to data, analysis tools and processing power by means of a Science Gateway. But how will SRCs face the challenge of supporting Open Science? By definition, scientists want to follow the Scientific Method and therefore to ensure the reproducibility of their scientific results. However, something is failing when 70% of around 1500 researchers inquired in a questionnaire on reproducibility answered that they have tried and failed to reproduce another scientist's experiments and >50 % have failed to reproduce their own experiments. If scientists are not capable of achieving reproducibility with the current data volumes, how will they do it with such large data volumes as those generated by the SKA? How will then SRCs support astronomers to build reproducible methods? The project SKA-Link is trying to help answering these questions by gathering members of the consortium in charge of designing the SDP, experts involved in the definition of the SRCs and specialists on e-Science technologies, to elaborate a general framework of Best Practices that assist the SKA community to successfully exploit the immense flow of SKA data, with an emphasis on tools that facilitate the reproducibility of the scientific methods and their verification. Virtual Research Environments and Science Gateways are some of the technologies supporting open and reproducible science. Would they fulfil the SKA community requirements? What barriers will be found by this community when putting these technologies into practice? How could they be overcome? In this talk we will present the work carried out so far by the SKA-Link project, which is coordinated by the AMIGA group from the Instituto de Astrofísica de Andalucía (IAA-CSIC) and funded by the Spanish National Research Council (CSIC).

Summary

The Square Kilometre Array (SKA) radiotelescope will be the greatest data research public project. SKA Regional Centres (SRCs) will face the challenge of providing access to data, tools and computational power required to process them, through a Science Gateway.

How will SRCs support Open Science and facilitate the building of reproducible methods? Science Gateways support open and reproducible science. Would they fulfil the SKA community requirements? What barriers will be found by this community and how could they be overcome?

We will present the work carried out so far by the SKA-Link project, trying to answer these questions.
