Glacier hydrology an introduction

By Bethan Davies / AntarcticGlaciers.org Introduction | Supraglacial hydrology | Englacial hydrology | Subglacial hydrology | Proglacial drainage | References Introduction Glacier hydrology is the study of the flow of water through glaciers. It is a mysterious world, where water running on the surface of the glacier disappears through cracks and holes in the glaciers,…

A closer look at subglacial glacier cavities and water pressure

A collection of science around subglacial glacier’s, cavities and about water pressure/water flow. Though someone pointed out that most of the items are focused on land based glaciers, rather than on the WAIS which is a marine ice sheet. However, i welcome all contribution in the comment section which helps to better understand marine ice…

West Antarctic rapid glacier retreat may be exceptional during the Holocene

Ice loss from the marine-based, potentially unstable West Antarctic Ice Sheet (WAIS) contributes to current sea-level rise and may raise sea level by ≤3.3 m or even ≤5 m in the future. Over the past few decades, glaciers draining the WAIS into the Amundsen Sea Embayment (ASE) have shown accelerated ice flow, rapid thinning, and…
