Signals from the streamer are digitised by the renowned Geometrics Geode seismograph. The intuitive data acquisition software can be run on a standard Laptop PC. All components of the recording system can be run from 12V batteries permitting the system to be operated from any vessel.

The system is light weight and can be deployed by hand from a small vessel. The MicroEel is ideal for geological engineering projects in shallow water.

The MicroEel opens the door to affordable multichannel seismic data acquisition.

Features
