Oceanographic Scenario Oceanographic Scenario [A. Maffei/WHOI][A. Maffei/WHOI]
• Imagine you are an oceanographer interested in undersea earthquakes. You have deployed instrument clusters of acoustic, chemical, seismic, etc. sensors with acoustic modems attached to them.
• Autonomous Underwater Vehicles (AUVs) gather data from the instruments on a regular basis. Sometimes you make special requests to gather data from specific instruments, for example after an underwater earthquake occurs.

Scientist Interactions with Scientist Interactions with Instrument PlatformsInstrument Platforms
• As an oceanographer you don’t concern yourself about which data communications assets are used to deliver commands to instruments or how data is delivered back to you.
• For example, a dtn_file_copy or dtn_traceroute command might be issued from your workstation command line indicating a DTN region and an oceanographic instrument name inside that region.
• The command might complete 3 weeks later when email arrives telling you that the data has arrived or displaying a report showing the communications path and sample round-trip latency to the instrument(s) you are interested in.
