Article in Journal of Glaciology, Firn aquifer water discharges into crevasses across Southeast Greenland, published online by Cambridge University Press, 17 May 2023, studies how winter snowfall and summer melt give rise to firn aquifers - stores of meltwater beneath ice-sheets. The study supports the idea "that most water in Southeast Greenland firn aquifers drain through crevasses.
In addition to tools and supercomputing resources to identify crevasses from data collected from NASA, the study used a tool developed in GHub.
The article explains how it used Ghub, "a science gateway providing browser-based access to data sets, analysis tools and super-computing resources for ice sheet science (https://theghub.org). The Ghub gateway is built on the HUBzero platform".
The tool developed on Ghub is called the ABCDE tool, or ATM-Based Crevasse Detection and Extraction workflow. The tool identifies crevasses from NASA's ATM (Airborne topographic mapper), a high resolution laser altimeter.
