Patent Images
1. A system for monitoring ice floe movement comprising:
- a) a satellite based system for acquiring SYNTHETIC APERTURE RADAR (SAR) images of ice floes;
b) an underwater UPWARD LOOKING SONAR (ULS) system located in an autonomous underwater vehicle for acquiring ice thickness data; and
c) a control unit for receiving and combining said SAR images and said thickness data by overlay of the ice thickness data on the SAR images in a single display to allow direct visualization of areas of ice having more than a threshold thickness which is a risk.

Abstract
Autonomous Underwater Vehicles (AUV) collect and transmit information about ice floe thickness; this is combined with SYNTHETIC APERTURE RADAR images from satellites to identify and track dangerously thick regions of ice. The overlayed data is presented graphically to allow tracking of the thick ice regions over time. This information is used to alert drilling platforms in icy ocean conditions of pending ice floe dangers.
