  • Glacier thinning, recession and advance, and the associated evolution of a glacial lake between 1966 and 2021 at Austerdalsbreen , western Norway

    Open AccessGernot Seier, Jakob Abermann et al.ARTICLELand Degradation and Development2024

    The Jostedalsbreen is the largest ice cap in Norway and mainland Europe. Rapid retreat of many of its outlet glaciers since the 2000s has led to the formation of several glacial lakes. Processes causing the formation and expansion of glacial lakes and their interaction with a glacier and terminal moraine have not been widely addressed yet. In this study, we investigate the degradation of the front of the southeast‐facing outlet glacier Austerdals…

  • Shallow soils are warmer under trees and tall shrubs across Arctic and Boreal ecosystems

    Open AccessHeather Kropp, M M Loranty et al.ARTICLEEnvironmental Research Letters2020

    Soils are warming as air temperatures rise across the Arctic and Boreal region concurrent with the expansion of tall-statured shrubs and trees in the tundra. Changes in vegetation structure and function are expected to alter soil thermal regimes, thereby modifying climate feedbacks related to permafrost thaw and carbon cycling. However, current understanding of vegetation impacts on soil temperature is limited to local or regional scales and lack…

  • Deltas, freshwater discharge, and waves along the Young Sound, NE Greenland

    Open AccessAart Kroon, Jakob Abermann et al.ARTICLEAMBIO2017References: 19

    A wide range of delta morphologies occurs along the fringes of the Young Sound in Northeast Greenland due to spatial heterogeneity of delta regimes. In general, the delta regime is related to catchment and basin characteristics (geology, topography, drainage pattern, sediment availability, and bathymetry), fluvial discharges and associated sediment load, and processes by waves and currents. Main factors steering the Arctic fluvial discharges into…

  • Transitions in high-Arctic vegetation growth patterns and ecosystem productivity tracked with automated cameras from 2000 to 2013

    Open AccessAndreas Westergaard-Nielsen, Andreas Westergaard‐Nielsen et al.ARTICLEAMBIO2017Cited by: 1References: 43

    Climate-induced changes in vegetation phenology at northern latitudes are still poorly understood. Continued monitoring and research are therefore needed to improve the understanding of abiotic drivers. Here we used 14 years of time lapse imagery and climate data from high-Arctic Northeast Greenland to assess the seasonal response of a dwarf shrub heath, grassland, and fen, to inter-annual variation in snow-cover, soil moisture, and air and soil …

  • Vegetation phenology gradients along the west and east coasts of Greenland from 2001 to 2015

    Open AccessMojtaba Karami, Birger Ulf Hansen et al.ARTICLEAMBIO2017Cited by: 1References: 33

    The objective of this paper is to characterize the spatiotemporal variations of vegetation phenology along latitudinal and altitudinal gradients in Greenland, and to examine local and regional climatic drivers. Time-series from the Moderate Resolution Imaging Spectroradiometer (MODIS) were analyzed to obtain various phenological metrics for the period 2001-2015. MODIS-derived land surface temperatures were corrected for the sampling biases caused…

  • Towards quantifying the glacial runoff signal in the freshwater input to Tyrolerfjord–Young Sound, NE Greenland

    Open AccessMichele Citterio, Mikael K Sejr et al.ARTICLEAMBIO2017References: 40

    Terrestrial freshwater runoff strongly influences physical and biogeochemical processes at the fjord scale and can have global impacts when considered at the Greenland scale. We investigate the performance of the HIRHAM5 regional climate model over the catchments delivering freshwater to Tyrolerfjord and Young Sound by comparing to the unique Greenland Ecological Monitoring database of in situ observations from this region. Based on these finding…

  • Hotspots and key periods of Greenland climate change during the past six decades

    Open AccessJakob Abermann, Birger Ulf Hansen et al.ARTICLEAMBIO2017References: 33

    We investigated air temperature and pressure gradients and their trends for the period 1996-2014 in Greenland and compared these to other periods since 1958. Both latitudinal temperature and pressure gradients were strongest during winter. An overall temperature increase up to 0.15 °C year -1 was observed for 1996-2014. The strongest warming happened during February at the West coast (up to 0.6 °C year -1 ), weaker but consistent and significant …

  • Spatiotemporal variability in surface energy balance across tundra, snow and ice in Greenland

    Open AccessMagnus Lund, Christian Stiegler et al.ARTICLEAMBIO2017References: 39

    The surface energy balance (SEB) is essential for understanding the coupled cryosphere-atmosphere system in the Arctic. In this study, we investigate the spatiotemporal variability in SEB across tundra, snow and ice. During the snow-free period, the main energy sink for ice sites is surface melt. For tundra, energy is used for sensible and latent heat flux and soil heat flux leading to permafrost thaw. Longer snow-free period increases melting of…
