Arctic hydrological regime shift in a warming climate, Linnedalen, Svalbard: hydroclimate observations (2017-2023)

Long-term hydroclimate monitoring in Linnédalen, western Spitsbergen provides a baseline for understanding climate and environmental change in the rapidly warming 21st century climate in Svalbard. Monitoring watershed and climatological processes also provides the means for directly interpreting the annually resolved sedimentation record (varves) in proglacial Linnévatnet, which in turn, will allow for an understanding of the current hydroclimatic regime in a long-term context. Related sediment core data were submitted by our collaboration partners at the University of Massachusetts, Amherst. An automated weather station, snow depth and stream water temperature sensors, time-lapse cameras, and moorings in Linnévatnet have been deployed since 2003 in the 31 square kilometer (km2) catchment of Linnédalen. This project (2016-2023) follows hydroclimate studies initiated during the National Science Foundation - Office of Polar Programs (NSF-OPP) sponsored Svalbard Research Experience for Undergraduates (REU) which ran from 2003 to 2013 archived and research and teaching in Linnédalen while the project was affiliated with the University Centre in Svalbard 2016-2022. Data from the earlier phase of the Linnedalen monitoring project includes weather station measurements, time lapse photography, and student theses and reports was archived in the Arctic Data Center and can be found here: https://arcticdata.io/catalog/view/urn:uuid:1b96e994-20a1-4445-a327-3256c040034f
