  2. Oceanographic Scenario [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.

  3. Scientist Interactions with Instrument 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.
