Ice Thickness Distribution
Prototype Upward Looking Sonar (ULS) instruments that monitor time series of ice draft from oceanographic moorings have been designed, built, tested and deployed in arctic waters. The measured time series recovered from these instruments reveal many geophysically significant, quantitative aspects of...
