Advances in upward looking sonar technology for studying the processes of change in Arctic Ocean ice climate

Marko and Humfrey Melling}, journal={Journal of Operational Oceanography}, year={2008}, volume={1}, pages={18 - 9} }
A major impetus for scientific studies of climate change in the Arctic Ocean has been the reduction in the areal extent and thickness of its sea ice cover. An extended measurement record of the horizontal dimensions of this ice cover is available for the full Arctic Ocean Basin based upon a record compiled from more than 30 years of relatively continuous satellite based measurements. Unfortunately, data accumulations for the ice cover’s vertical dimension, ie, sea ice thickness, tend to be…
