Abstract
A self-contained data acquisition unit is provided for acquiring seismic data. The unit has a microprocessor and an antenna adapted to receive an electromagnetic signal. A decoder is connected with the microprocessor and adapted to convert received electromagnetic signals to dual-tone multiple-frequency ('DTMF') digits. A geophone interface is provided with a geophone for collecting acoustic data incident on the geophone. A memory is connected with the geophone interface for storing a representation of the collected acoustic data and for storing a representation of a reference electromagnetic signal to be used in synchronizing acoustic data collected by other data acquisition units. A battery power source is connected with the microprocessor.
