Deformation, Ecosystem Structure and Dynamics of Ice (DESDynI)

Status: Eliminated
Mission Category: Earth Systematic Missions, Decadal Survey 2007, Tier 1

Eliminated in President's FY12 Budget.

The radar portion of DESDynl has become the NI-SAR mission, while the lidar portion of DESDynl overlaps with the GEDI mission. 

Surface deformation is linked directly to earthquakes, volcanic eruptions, and landslides. Observations of surface deformation are used to forecast the likelihood of earthquakes occurring as a function of location, as well as predicting both the place and time that volcanic eruptions and landslides are likely. Global observations of surface deformation will lead to advances in earthquake science. Improved time-dependent probabilities will benefit the health and safety of the public by decreasing the exposure to tectonic hazards. Monitoring surface deformation is also important for improving the safety and efficiency of hydrocarbon extraction, managing ground water resources, and, in the future, CO2 sequestration management.
