An autonomous drifting seismic buoy for acquisition of single channel seismic reflection data from drifting sea ice in the Arctic Ocean and real-time data transmission to shore via Iridium
Picture: The Seisdrift seismic buoy.
The Seisdrift concept was proposed during the International Polar Year by the University of Bergen. The Seisdrift buoy consists of control electronics, a 4.6 kJoule sparker and a hydrophone. Guided by position information from a GPS unit, the buoy triggers the sparker and collects and stores the data automatically onto disk. Extracts of the data, short burst data packet, are sent over the Iridium satellite network to a web server at CMR. The same server is also used to send messages to the Seisdrift buoy in order to change acquisition period, acquisition length and other parameters.
The Seisdrift buoy was developed in 2009 at CMR. CMR has developed the system control electronics and the communication module.
