Abstract: Oil fields in the North Caspian Sea are currently being evaluated. Ice is one design concern for these developments. Relatively little ice environmental data are available for evaluating development alternatives. The paper describes recent efforts to obtain ice thickness data, and stamukha surface topography. Ice thickness data were collected over several long transects by deploying a Ground Penetrating Radar (GPR) from a helicopter. This deployment followed testing done during the 2000–2001 winter in an outdoor basin and in the Saguenay River in brackish ice, which were used to establish the preferred GPR system. A laser scanner was used from a helicopter to map the surface topography of ice rubble fields at drilling structures, and of stamukhas.
