Monitoring the Deepwater Horizon well.

Following up on yesterday's entry (Deepwater Horizon should not become our Event Horizon), here is one set-up that could be used to monitor the conditions of the Deepwater Horizon well and its surroundings as the relief well gets close to the main well. In this configuration, the wave is seismic but it can be adapted with nuclear and other types of probing measurements. Compressive Sensing provides a nice way to demultiplex all these signals but more importantly it can detect with few measurements changes in the configuration of the soil.
