The main objective of the PermaSense project is to build and customize a set of wireless measurement units for use in remote areas with harsh environmental monitoring conditions. The second goal is the gathering of environmental data that helps to understand the processes that connect climate change and rock fall in permafrost areas. To this end, two sensor fields will be deployed in the Swiss alps and be operated over several years.

Wireless sensors contribute to permafrost science. They will enable to easily monitor larger permafrost areas with denser sampling, leading to better predictions on the consequences of global warming for alpine regions.

Beyond helping the modelling of permafrost processes, this research is also applicable to natural hazard surveillance. Currently, there is lack of easy to deploy geo-monitoring systems that are low-cost, cheap in maintenance, and easily reconfigurable when deployed. With better wireless sensor solutions, larger hazard areas can be permanently monitored and linked to warning system that help to protect human lives.

What has been achieved so far? The consequences of global warming due to permafrost degradation cannot be predicted yet in an appropriate manner. Furthermore, there is an urgent need for continuous environmental monitoring at various time scales. Finally, there is still a lack of cheap and easy to deploy stand-alone monitoring and warning systems.

Where does the project stand now? The project begins in the fall of 2005. The first generation of sensors shall be ready early summer 2006 where climatic conditions permit to deploy them. After that, access is more or less impossible for the span of a year, during which continuous measurements will be done.
