Seismic-data acquisition methods and apparatus
First Claim
1. A self-contained data acquisition unit for acquiring seismic data, the data acquisition unit comprising:
- a microprocessor;
an antenna adapted to receive an electromagnetic signal;
a decoder connected with the microprocessor and adapted to convert received electromagnetic signals to dual-tone multiple-frequency (“
DTMF”
) digits;
a geophone interface with a geophone for collecting seismic data incident on the geophone;
a memory connected with the geophone interface for storing a representation of the collected seismic data and for storing a representation of a reference electromagnetic signal to be used in synchronizing seismic data collected by other data acquisition units; and
a battery power source connected with the microprocessor.

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.
