The chronology of reindeer hunting on Norway's highest ice patches
Pilø, Lars Holger; Finstad, Espen; Bronk Ramsey, Christopher; Martinsen, Julian Robert Post; Solli, Brit; Nesje, Atle; Wangen, Vivian; Callanan, Martin; Barrett, James H. (Peer reviewed; Journal article, 2018-01-24)The melting of perennial ice patches globally is uncovering a fragile record of alpine activity, especially hunting and the use of mountain passes. When rescued by systematic fieldwork (glacial archaeology), this evidence ... -
Evidence for rapid paraglacial formation of rock glaciers in southern Norway from 10Be surface-exposure dating
Linge, Henriette; Nesje, Atle; Matthews, John A.; Fabel, Derek; Xu, Sheng (Journal article; Peer reviewed, 2020-04-16)We evaluate the timing and environmental controls on past rock-glacier activity at Øyberget, upper Ottadalen, southern Norway, using in situ 10Be surface-exposure dating on (1) boulders belonging to relict rock-glacier ... -
Holocene debris flows recognized in a lacustrine sedimentary succession: sedimentology, chronostratigraphy and cause of triggering
Sletten, K.; Blikra, Lars Harald; Ballantyne, C. K.; Nesje, Atle; Dahl, Svein Olaf (Peer reviewed; Journal article, 2003)This study focuses on the sedimentary characteristics and the chronostratigraphy of Holocene massflow deposits recognized in a lake-fill sedimentary succession. These deposits in lake Ulvådalsvatnet, western Norway, are ... -
Holocene glacier variability and Neoglacial hydroclimate at Ålfotbreen, western Norway
Gjerde, Marthe; Bakke, Jostein; Vasskog, Kristian; Nesje, Atle; Hormes, Anne (Peer reviewed; Journal article, 2016-02)Glaciers and small ice caps respond rapidly to climate perturbations (mainly winter precipitation, and summer temperature), and the mass-balance of glaciers located in western Norway is governed mainly by winter precipitation ... -
Identifying climate change information needs for the himalayan region: Results from the GLACINDIA Stakeholder Workshop and Training Program
Koldunov, Nikolay V.; Kumar, Pardeep; Rasmussen, Ragnar; Ramanathan, A.L.; Nesje, Atle; Engelhardt, Markus; Tewari, Muneesh; Haensler, A.; Jacob, D (Journal article, 2016)Here we present results of a workshop designed to bring together stakeholders from different states of the Indian side of the Himalayan arc and an international group of climate scientists in order to discuss how climate ... -
Interpreting archaeological site-formation processes at a mountain ice patch: A case study from Langfonne, Norway
Solli, Brit; Pilø, Lars Holger; Barrett, James H; Eiken, Trond; Finstad, Espen; Grønning, Sunniva; Post-Melbye, Julian R.; Nesje, Atle; Rosvold, Jørgen; Ødegård, Rune Strand (Journal article; Peer reviewed, 2021)In the context of global warming, ice patches are increasingly important foci of high-elevation archaeology. Langfonne in Jotunheimen, central southern Norway, is uniquely suited to provide a window onto site formation ... -
The 'Little Ice Age' – only temperature?
Nesje, Atle; Dahl, Svein Olaf (Peer reviewed; Journal article, 2003)Understanding the climate of the last few centuries, including the 'Little Ice Age', may help us better understand modern-day natural climate variability and make climate predictions. The conventional view of the climate ... -
Pervasive cold ice within a temperate glacier – implications for glacier thermal regimes, sediment transport and foreland geomorphology.
Reinardy, Benedict T.I.; Booth, Adam D; Hughes, Anna L.C.; Boston, Clare M.; Åkesson, Henning; Bakke, Jostein; Nesje, Atle; Giesen, Rianne H.; Pearce, Danni (Peer reviewed; Journal article, 2019-03-07)This study suggests that cold-ice processes may be more widespread than previously assumed, even within temperate glacial systems. We present the first systematic mapping of cold ice at the snout of the temperate glacier ... -
Spatial patterns of North Atlantic Oscillation influence on mass balance variability of European glaciers
Marzeion, Ben; Nesje, Atle (Peer reviewed; Journal article, 2012-06-14)We present and validate a set of minimal models of glacier mass balance variability. The most skillful model is then applied to reconstruct 7735 individual time series of mass balance variability for all glaciers in the ... -
Spring-summer temperature reconstruction in western Norway 1734-2003: a data-synthesis approach
Nordli, Øyvind; Lie, Øyvind; Nesje, Atle; Dahl, Svein Olaf (Peer reviewed; Journal article, 2003-12-16)A series of spring–summer (April–August) temperatures was reconstructed for the period 1734–1923 for western Norway based on multi-proxy data. For the period 1734–1842 the long-term variations were based on terminal moraines ... -
Subglacial sediment distribution from constrained seismic inversion, using MuLTI software: examples from Midtdalsbreen, Norway
Killingbeck, Siobhan F; Booth, Adam D; Livermore, Philip W; West, Landis J; Reinardy, Benedict T.I.; Nesje, Atle (Journal article; Peer reviewed, 2019)Fast ice flow is associated with the deformation of subglacial sediment. Seismic shear velocities, Vs, increase with the rigidity of material and hence can be used to distinguish soft sediment from hard bedrock substrates. ... -
A theoretical approach to glacier equilibrium-line altitudes using meteorological data and glacier massbalance
Lie, Øyvind; Dahl, Svein Olaf; Nesje, Atle (Peer reviewed; Journal article, 2003-05-01)Based on a close exponential relationship between mean ablation-season temperature and winter precipitation at the equilibrium-line altitude (ELA) of 10 Norwegian glaciers, three equations are derived. The first equation ... -
Theoretical equilibrium-line altitudes and glacier buildup sensitivity in southern Norway based on meteorological data in a geographical information system
Lie, Øyvind; Dahl, Svein Olaf; Nesje, Atle (Peer reviewed; Journal article, 2003-05-01)Three equations derived from a close exponential glacier-climate relationship at the equilibrium-line altitude (ELA) of Norwegian glaciers have been utilized and implemented in a geographical information system (GIS). The ...
