Global clustering of recent glacier surges from radar backscatter data, 2017–2022

A Theory of Glacier Surges

We propose a model of glacier flow for at least a hundred years, and a major conthat is capable of explaining temperate glacier ference (see Canadian Journal of Earth Sciences, surges. The laws of conservation of mass and vol. 6, pp. 807-1018, 1969) was devoted to their momentum are supplemented by the prescription study. Meier and Post [1969] summed up many of of a sliding law that gives the b...

A Mathematical Analysis of Glacier Surges

This paper describes the phenomena of glacier surges and presents a mathematical model based on realistic descriptions of glacier physics, which purports to describe the main features of the flow. The analysis reveals and predicts a variety of phenomena, many of which have been observed to occur, and gives explicit estimates for such quantities as surge front extent, "mini-surge" propagation sp...

The evolution of a submarine landform record following recent and multiple surges of Tunabreen glacier, Svalbard

This study focuses on the glacial landform record associated with recent surge events of Tunabreen a calving tidewater glacier in Tempelfjorden, Spitsbergen. Submarine geomorphology and recent terminal fluctuations of Tunabreen’s glacier front were studied using high-resolution multibeambathymetric data and a range of published and remotesensing sources, including topographic maps, satellite im...

Anomalous Radar Backscatter from Titan’s Xanadu

Introduction and Summary: The comparison of an observed surface's microwave reflectivity and its passive emission directly addresses the relationship of the measured radar backscatter to the overall reflective properties of the surface. The simultaneous radiometry and radar reflectivity obtained by the Cassini Radar instrument has uniquely allowed us to investigate the backscattering enhancemen...
