The ability to understand and predict environmental changes in Svalbard is highly dependent on the availability of detailed and long-term records of baseline environmental data from a regional network across the archipelago. The Kapp Linné region provides a strategic location for a dedicated long-term environmental observatory in the western coastal region of the Nordenskiöldland Peninsula. This region is greatly influenced by the Atlantic High Arctic maritime climate regime (Eckerstorfer and Christiansen 2011) with higher mean annual air temperature and greater precipitation than the more continental interior regime in central Spitsbergen (Humlum 2002). With the recent intensified Atlantification of the northern Barents Sea (Nilsen et al. 2016; Barton et al. 2018), environmental monitoring studies along the Nordenskiöldland coast may help to serve as an early warning system for climate change and accompanying environmental responses across the Svalbard archipelago.

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

Abstract Mechanisms behind the phenomenon of Arctic amplification are widely discussed. To contribute to this debate, the (AC) 3 project was established in 2016 ( www.ac3-tr.de/ ). It comprises modeling and data analysis efforts as well as observational elements. The project has assembled a wealth of ground-based, airborne, shipborne, and satellite data of physical, chemical, and meteorological properties of the Arctic atmosphere, cryosphere, and upper ocean that are available for the Arctic climate research community. Short-term changes and indications of long-term trends in Arctic climate parameters have been detected using existing and new data. For example, a distinct atmospheric moistening, an increase of regional storm activities, an amplified winter warming in the Svalbard and North Pole regions, and a decrease of sea ice thickness in the Fram Strait and of snow depth on sea ice have been identified. A positive trend of tropospheric bromine monoxide (BrO) column densities during polar spring was verified. Local marine/biogenic sources for cloud condensation nuclei and ice nucleating particles were found. Atmospheric–ocean and radiative transfer models were advanced by applying new parameterizations of surface albedo, cloud droplet activation, convective plumes and related processes over leads, and turbulent transfer coefficients for stable surface layers. Four modes of the surface radiative energy budget were explored and reproduced by simulations. To advance the future synthesis of the results, cross-cutting activities are being developed aiming to answer key questions in four focus areas: lapse rate feedback, surface processes, Arctic mixed-phase clouds, and airmass transport and transformation.more » « less

In Arctic landscapes, watershed processes are tightly linked to cold temperatures, permafrost, snow, and strong seasonality in precipitation, storage, and runoff. Thus, a rapidly changing Arctic climate will affect watershed function and result in changes to the transport of water, sediment, and nutrients to downstream aquatic and marine ecosystems. There is increasing evidence of hydrologic intensification of the Arctic terrestrial water cycle, fueling inquiry into the hydrologic responses that integrate the varying climate and landscape units. Key to understanding these complex watershed processes is long-term hydrologic monitoring in Arctic Alaska. The goal of this study is to operate and maintain hydroclimate observation stations in the Kuparuk River basin to obtain continuous datasets for the community of Arctic stakeholders. Imnavait Creek is a small (2.2 square kilometers) watershed located in the northern foothills region of Brooks Range and the headwaters of the Kuparuk River. The Kuparuk River flows north through the foothills and coastal plain of Alaska, before discharging into the Beaufort Sea. The gauging station at Imnavait Creek is approximately 3 kilometers south of the Dalton Highway, near MP (milepost) 291. Imnavait Creek parallels the Upper Kuparuk River and enters the Kuparuk River 12 kilometers north of the Water and Environmental Research Center (WERC) Upper Kuparuk gauging station. Streamflow at Imnavait Creek persists throughout the summer months, but during the winter months flow is non-existent. Streamflow in Imnavait Creek has been measured by researchers at the University of Alaska Fairbanks (UAF) WERC from 1985 to 2023. This data package contains continuous streamflow data collected by researchers from University of Alaska Fairbanks from 2018-2023. For UAF-WERC historical discharge data for Imnavait Creek (1985-2017) see the data package at https://arcticdata.io/catalog/view/doi%3A10.18739%2FA2K649S9D.more » « less
