Abstract
Abstract. Here we present an algorithm for continuous ice dynamics estimation based on coastal and ship radar data. The ice dynamics are estimated based on automatically selected ice targets in the images. These targets are here called virtual buoys (VB's) and are tracked based on an optical flow method. To maintain continuous ice drift tracking new VB's are added after a~given number of VB's have been lost i.e. they can not be tracked reliably any more. Some tracking results and some computed derived quantities for a~few test cases are presented.
