Geophysical data acquisition - OGS

Sea, close to the Antarctic Peninsula, in co-operation with the US Antarctic
Program, the other off the Wilkes Land, in co-operation with the Australian
Antarctic Program.
The 200 budget for these studies was 450,000 EURO, mainly supported by the
Italian Antarctic Program.
The main problem we are facing in the application of the traditional onshore
seismic to environmental and hydrogeological studies, is the need to drastically
increase the resolution of the method: our approach follows three convergent
directions: i) by a theoretical approach based on the study and modelling of the
propagation of P and S waves in heterogenous-visco-elastic media; ii) studying the
source, by the acquisition of an high frequencies (up to 400 Hz) vibroseis system;
iii) the processing, by the application of evolved statics computation techniques.
The 2000 budget for these researches was about 500,000 EURO, mainly supported
by the Ministry for University and Research and by Fondo Trieste.
During the 2000, the GdL was also involved in significant activities for the oil
industry, particularly Agip. These were based on the Seisbit tecnology that was
applied for monitoring the bit position and carring direct and reverse WSP while
drilling.
The total budget for these activities was 1,230,000 EURO.
