During the two winters between 2003 and 2005, a land-based marine radar observed the nearshore ice motion during the development and decay of landfast ice near Barrow, Alaska. The radar imagery captured individual events at high temporal resolution, revealing deformation processes and allowing calculation of ice velocity and acceleration. Atmospheric(More)
With image capturing technology growing ubiquitous in consumer products and scientific studies, there is a corresponding growth in the applications that utilize scene structure for deriving information. This trend has also been reflected in the plethora of recent studies on reconstruction using robust structure from motion, bundle adjustment, and related(More)
Techniques based on the well-studied approaches of structure from motion and bundle adjustment are very robust for scenes with texture. In scenes with little texture information these approaches can fail. Shape from shading determines the shape of an object up to a scale from a single image, and performs better than structure from motion methods in(More)
Genetic profiling links changing sea-ice to shifting beluga whale migration patterns. One contribution to the special feature 'Effects of sea ice on Arctic biota'. There is increasing concern over how Arctic fauna will adapt to climate related changes in sea-ice. We used long-term sighting and genetic data on beluga whales (Delphinapterus leucas) in(More)
