NEPTUNE Canada Ocean Sciences Enters the Data- Intensive Scene Benoît Pirenne, University of Victoria, BC, Canada
Benoît Pirenne, München, March 15, 2010 What is NEPTUNE Canada? Use transoceanic telecom cables to provide power and comms to instruments on the seabed. Provide up to 9kW of power to 5 locations on the seabed 4Gbps per location to shore Capacity for hundreds of instruments, 1000's of sensors Much denser sampling of the environment.
Why NEPTUNE? The last century of oceanography is marked most by the degree of undersampling Walter Munk (2001) Plate tectonic processes and earthquake dynamics Dynamic processes of fluid fluxes and gas hydrates in the sea bed Regional ocean/climate dynamics and effects on marine biota Deep-sea ecosystem dynamics Engineering and computational research
Benoît Pirenne, München, March 15, 2010 Data Management and Archiving System Extension of the Internet under the Ocean Expensive, unique, shared resource -> management Ocean data volumes to be multiplied by 10 6 / year Constant number of scientists available to deal with them Need to change the old expeditionary science paradigm Need new tools to deal with the issue of analysis, visualization --> Need to create an environment for collaboration --> Provide tools to support effective exploitation of data
Benoît Pirenne, München, March 15, 2010 Oceans 2.0 Take advantage of Web 2.0 paradigms to address issues Every tool is on-line, web-enabled Don't download data – upload code instead Every Web tool has aspects of contribution & collaboration Challenges: Sociological: get people to change the way they work IT: build an eScience/Cyber-Infrastructure environment adapted to Ocean scientist needs (many different disciplines!)
Benoît Pirenne, München, March 15, 2010 Oceans 2.0 Challenges Capture data from many different types of sensors Interact with underwater instrumentation (e.g., cameras) Keep data + metadata for 25 years Provide search, visualization capabilities, various data products Allow for X-correlation between data from various sensors Detect and react to events
Benoît Pirenne, München, March 15, 2010 Oceans 2.0 Cyber-Infrastructure needs in our case: Download data – Upload code Easy, managed Cloud Computing access Unified authentication mechanism / single sign-on to access many distributed services Uniform data access to exchange data with other providers (but usually discipline specific).
