The article presents a study which aims to determine the thermal structure and drainage system of a small valley glacier in Svalbard, Norway. It examines a large proglacial icing that develops during winter accumulating many High Arctic glaciers along with the drainage system of Tellbreen, a long cold-based polythermal glacier. Tellbreen showed diverse drainage system capable of storing, transporting, and releasing water noting a channelized subglacial drainage system for storage and discharge.
