MARS – Monterey Accelerated Research System Carbon Budget at canyon mouth Canyon dynamics – sediment transport Deep-sea ecology Seismometry Cold-seep geochemistry and biology

Basic Phys-O +

Basic Phys-O Sensor Package - 1 Barotropic and 1 st mode Baroclinic velocity and density –Horizontal Electric Field for barotropic velocity –Pressure –Inverted echosounder Round trip travel time to surface Backscatter Acoustic tomography, possibly geodesy Ambient sound (earthquakes, ships, whales, wind, rain) General purpose acoustic communications General purpose acoustic navigation beacon

Basic Phys-O Sensor Package - 2 Sensor network infrastructure –Secondary J-boxes –Cables, connectors, in-line media converters Develop and test here (Friday Harbor?) Test a small array (5 – 10) on MARS 5 year, NSF Instrumentation People: –Tom Sanford, Bruce Howe, Tim McGinnis, … –Doug Luther, UH –Work with Lee Freitag (WHOI) on acoustic comms

Keck/NEPTUNE Simulator Node Can use/adapt a Secondary J-box –Provides most functionality of NEPTUNE –Ethernet/RS232 “Backbone Cable” = –External battery –Acoustic modem
