  1. The SEAMONSTER Sensor Web: Lessons and Opportunities after One Year DR Fatland1, MJ Heavner2, E Hood2, C Connor2 1 Vexcel/Microsoft, 2 University Alaska Southeast 1

  2. Outline • What is SEAMONSTER? • What are the goals of SEAMONSTER? • How to encourage/facilitate collaboration • Lessons Learned 2

  3. SouthEastAlaskaMOnitoringNetwork forScienceTechnologyEducation and Research SEAMONSTER Tlingit carving of Gunakadeit A modern seamonster tentacle We seek inspiration from the Tlingit legend of Gunakadeit, a seamonster who brought fish and furs to an impoverished village. The modern parallel is harvesting and distributing geospatial information via a sensor web to a world struggling with climate change. 3

  4. SEAMONSTER • Scientifically Motivated Sensor Web Technology Development • Testbed Sensor Web > Technology Collaborations • Path for Technology Infusion > Scientific Collaborations 4

  5. Sensor Web Concept The sensor web also encompasses a system-of-systems aspect, by virtue of the important fact that it interacts with a wide variety of external entities, including external systems and users. 5

  6. 50 km Scientific Motivation, 1 Long term monitoring of the Juneau Icefield to observe watershed and ocean ecological impacts of glacial recession 6

  7. Scientific Motivation, 2 Detection of transient glacial lake outburst floods and observation for watershed impacts Lake post-drainage Lake pre-drainage 7

  8. Lemon Creek Watershed 5 km The University of Alaska Southeast has (relatively) easy access to these areas. The initial watershed of interest is the Lemon Creek watershed (fed by Lemon Glacier) which can be entirely accessed via hiking. Lemon Glacier was monitored as part of IGY (1957-58) and is again being studied during IPY (2007-8). 8

  9. Lemon Creek Sensor Web Met Station, Web Cam, Comm Hub Lake Level, GPS, Geophone Met Station, Web Cam Water Qual, USGS Gauge Water Qual Communication between the nodes enables the Sensor Web. Ex: pressure transducer ( ) detects lake drainage and passes the message reconfiguring other sensor behavior. 10

  10. Project Challenges • Resource management • Power constrained (batteries and solar) • Also: storage, bandwidth, processing • Different sampling requirements • Long term monitoring • Transient, rapidly evolving events • NEED SEMI-AUTONOMY or AGENTS 11

  11. Goals of SEAMONSTER • Event -> End User Sensor Web • Technology Testbed • Science • Technology Infusion • Education 12

  12. Goals of SEAMONSTER • Event -> End User Sensor Web • Technology Testbed • Science • Technology Infusion • Education • How to? Collaboration 13

  13. Example Collaboration, Tech Need: Software agents to reconfigure data acquisition based on observations and sensor web state. Specifically: If the lake pressure transducer measures a drop in lake level: 1. Retask the camera to focus on the lakes 2. Alert systems down the watershed to collect (relax power management) Our Solution: Conceptual, minimal implementation 14
