Naegeli, Kathrin Lovell, Harold Zemp, Michael Benn, Douglas I. 2014 The routing and storage of meltwater and the configuration of drainage systems in glaciers exert a profound influence on glacier behaviour. However, little is known about the hydrological systems of cold glaciers, which form a significant proportion of the total glacier population in the climate sensitive region of the High Arctic. Using glacio-speleological techniques, we obtained direct access to explore and survey three conduit systems and one moulin within the tongue area of Tellbreen, a small cold-based valley glacier in central Spitsbergen. More than 600 m of conduits were surveyed and mapped in plan, profile and cross-section view to analyse the configuration of the drainage system. The investigations revealed that cold-based glaciers can exhibit a dendritic drainage network with supra-, en- and subglacial components formed most likely by cut-and-closure processes as well as surface-to-bed drainage via moulins. Furthermore, we observed that water is stored within the glacier and released gradually via subglacial conduits during the winter months, forming a large and active icing in the proglacial area. The presence of supra-, en- and subglacial components, the surface-to-bed moulin and the dendritic subglacial drainage network suggest that existing models and understanding of the hydrology of cold glaciers needs to be re-evaluated, mostly concerning the different possible pathways and processes that form the hydrological system. application/pdf https://sonar.ch/global/documents/304135 https://sonar.ch/documents/304135/files/nae_dsd.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1111/geoa.12059 info:eu-repo/semantics/openAccess License undefined Geografiska Annaler: Series A, Physical Geography. - 2014, vol. 96, no. 4, p. 591–608 cold glaciers englacial subglacial conduit glacier hydrology glacio speleology icings Svalbard info:eu-repo/classification/udc/556 Dendritic subglacial drainage systems in cold glaciers formed by cut-and-closure processes http://purl.org/coar/resource_type/c_6501
