Persistence of arctic-alpine flora during 24,000 years of environmental change in the Polar Urals
Clarke, Charlotte, L.; Edwards, Mary, E.; Gielly, L; Ehrich, Dorothee; Hughes, P.D.M.; Morozova, L.M.; Haflidason, Haflidi; Mangerud, Jan; Svendsen, John-Inge; Alsos, Inger Greve (Peer reviewed; Journal article, 2019-12-23)Plants adapted to extreme conditions can be at high risk from climate change; arctic-alpine plants, in particular, could “run out of space” as they are out-competed by expansion of woody vegetation. Mountain regions could ... -
Rapid climate changes during the Lateglacial and the early Holocene as seen from plant community dynamics in the Polar Urals, Russia
Bjune, Anne E.; Greve Alsos, Inger; Brendryen, Jo; Edwards, Mary E.; Haflidason, Haflidi; Johansen, Maren S.; Mangerud, Jan; Paus, Aage; Regnéll, Carl; Svendsen, John-Inge; Clarke, Charlotte L. (Journal article; Peer reviewed, 2021)A detailed, well-dated record of pollen and sedimentary ancient DNA (sedaDNA) for the period 15 000–9500 cal a bp describes changes at Lake Bolshoye Shchuchye in the Polar Ural Mountains, located far east of the classical ... -
Rapid retreat of a Scandinavian marine outlet glacier in response to warming at the last glacial termination
Åkesson, Henning; Gyllencreutz, Richard; Mangerud, Jan; Svendsen, John-Inge; Nick, Faezeh M.; Nisancioglu, Kerim Hestnes (Journal article; Peer reviewed, 2020)Marine outlet glaciers on Greenland are retreating, yet it is unclear if the recent fast retreat will persist, and how atmosphere and ocean warming will impact future retreat. We show how a marine outlet glacier in ... -
Record-breaking height for 8000-Year-Old tsunami in the North Atlantic
Bondevik, Stein; Mangerud, Jan; Dawson, Sue; Dawson, Alastair; Lohne, Øystein S. (EOS : Transactions;Vol. 84, No.31, Journal article, 2003-08-05) -
The Scandinavian Ice Sheet as a barrier for Human colonization of Norway
Mangerud, Jan; Svendsen, John Inge (UBAS – Universitetet i Bergen Arkeologiske Skrifter;12, Chapter; Peer reviewed, 2022)Several times during the Last Ice Age, the ice sheet covered only mountain areas so that it theoretically was possible for humans to colonize coastal areas of Norway. The last time this happened prior to the Last Glacial ... -
The start of a major sea-level rise indicates that icesheet expansion in western Norway commenced before the Younger Dryas
Lohne, Øystein S.; Bondevik, Stein; Mangerud, Jan; Svendsen, John-Inge (Journal article, 2007)The relative sea level rose 10 m on Sotra, western Norway, during the Younger Dryas (YD). Based on dating of isolation basins, the transgression started in late Allerød at ~13 110 and ended in late YD at ~11 780 cal yr BP, ... -
The timing of deglaciation and the sequence of pioneer vegetation at Ringsaker, eastern Norway – and an earthquake-triggered landslide
Mangerud, Jan; Birks, Hilary H; Halvorsen, Lene Synnøve; Hughes, Anna L.C.; Nashoug, Ole; Nystuen, Johan Petter; Paus, Aage; Sørensen, Rolf; Svendsen, John-Inge (Peer reviewed; Journal article, 2018)We describe a sediment sequence comprising a thick till covered by thin beds of lacustrine sediments containing pollen and plant macrofossils derived from pioneer vegetation. Four consistent radiocarbon dates on terrestrial ... -
Tracing the last remnants of the Scandinavian Ice Sheet: Ice-dammed lakes and a catastrophic outburst flood in northern Sweden
Regnéll, Carl; Mangerud, Jan; Svendsen, John-Inge (Peer reviewed; Journal article, 2019-08-08)We present geomorphological evidence of large, previously undocumented, early Holocene ice-dammed lakes in the Scandinavian Mountains of northwestern Sweden. The lakes extents indicate that the last remnants of the ...
