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).
