The crawler "crawls" on dual tractor treads, which allow a full range of forward, backward and turning movement. Including its titanium frame, drive motors, sealed electronics chambers, wiring, lights, HD video camera, and sensors, the unit's out-of-water weight is 275 kg. With syntactic foam flotation blocks attached, this is reduced to an in-water weight of 40 kg. One unique feature is its control interface, which plugs directly into the Web. Interested people will be able to tune in to a live sea floor crawl on the NEPTUNE website. The crawler was named "Wally" (after the fictional Pixar robot

Gbit/s data channel is implemented on the spur cable, and each branching unit is connected to a regional node station. The connection between node stations and branching units provide one Gbit/s using a fiber-optic cable. Six node stations split the backhaul into six regions and the network behavior in between each regions' devices is identical. Similar to the connections between node stations and branching units, node stations are linked to junction boxes at one Gbit/s.
275:. Its small size and close proximity to the coast gives NEPTUNE Canada a unique opportunity to observe tectonic processes. NEPTUNE Canada is built to provide continuous observations for 25 years. The time-series data gathered will allow scientists to study long-term changes over the life of the project. Instruments comprising the undersea observatory will operate at depths ranging from 17 to 2,660 m. Hundreds of instruments have been connected to the Internet by way of

rates. More than ten components cannot be connected to a single junction box. Instruments can be linked to junction boxes or any other instrument through either data channel. The instruments are the final spots of the regional network branches. The data flows from the instruments through the edge of each regional branch toward UVIC DMAS by following a secure and shortest path, as configured by the network configurator used by NEPTSim.

These components are connected on a backbone of thick and insulated cable called a spur cable that has two separated lines for transmitting the data in opposite directions. The instruments transmit the data either clockwise or counter clockwise within a 2 by 2 Gbit/s data flow. Since the primary
