Geophysical data acquisition - OGS

Bathymetric map of the North Atlantic continental margin studied in the STRATAGEM
frame. WP1 is the Work Package 1 study area (the Norwegian margin); WP2 is the Work
Package 2 study area (the South Shetland-Faeroe margins); WP3 is the Work Package 3
study area (the Rockall Trough and Porcupine Basin).

OGS has a long tradition in gravimetry (i.e. the international gravity station
network IGSN71, Italian gravity map, marine gravity surveys in the Mediterranean
sea). Gravity surveys (land or marine) can be managed from planning, to field
acquisition, processing and interpretation. The INTE group has the responsibility
to manage and operate three LaCoste-Romberg gravity meters (one model D and
two model G), one underwater gravity meter LCR model H, one marine surface
gravity meter Bodenseewerk KSS31. These allow us to cover all the possible
applications of gravimetry:
At present our group is involved in the following projects:
1) A joint venture group OGS and SO.PRO.MAR has been entrusted by Servizio
Geologico Nazionale to carry out two marine gravity surveys in areas located
near Rome.
