The world’s glaciers and ice sheets are changing. Observations of glacier velocity (speed of ice flow), thickness, length and area alongside measurements of climate help us to understand this change. We can monitor these changes via remote sensing (using data from sensors mounted remotely, on things like UAVs and satellites), as well as from in …

An interesting new paper has just been published in Nature Geoscience by Romain Millan, Jeremie Mouginot, Antoine Rabatel and Mathieu Morligheim on the velocity and thickness of the world’s glaciers. They make a revised estimate of global glacier ice volume. They aren’t looking at ice in the Greenland or Antarctic ice sheets, just glaciers worldwide. …

Introduction | GLIMS glaciers | References | Comments | Introduction Antarctica has many different types of glacier. They range from enormous ice streams, arteries of fast flow that discharge the majority of the ice from the centre of the ice sheet to its edges[1], to slow-moving cold-based glaciers that are largely frozen to their beds[2]. …
