Monitoring of Sea Ice Dynamic by Means of Ers-envisat Tandem Cross-interferometry

The interest in the monitoring of sea ice masses has increased greatly over the past decades for a variety of reasons. These include: Navigation in northern latitude waters; transportation of petroleum; exploitation of mineral deposits in the Arctic, and the use of icebergs as a source of fresh water. The availability of ERS-Envisat 28minute tandem acquisitions from dedicated campaigns, covering large areas in the northern latitudes with large geometrical baseline and very short temporal separation, allows the precise estimation of sea ice displacement fields with an accuracy that cannot be obtained on large scale from any other instrument. This article presents different results of sea ice dynamic monitoring over northern Canada obtained within the “ERS-Envisat Tandem Cross-Interferometry Campaigns: CInSAR processing and studies over extended areas” project from data acquired during the 2008-2009 Tandem campaign..
