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

Data Management and Archiving System
Extension of the Internet under the Ocean
Expensive, unique, shared resource -> management
Ocean data volumes to be multiplied by 106 / 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

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!)

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

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).
