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.

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.

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

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

Lemon Creek Watershed
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).
5 km

Communication between the nodes enables the Sensor Web.Ex: pressure transducer ( ) detects lake drainage and passes the message reconfiguring other sensor behavior.

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

Example Collaboration, TechNeed: 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 lakes2. Alert systems down the watershed to collect (relax power management)
Our Solution: Conceptual, minimal
implementation
