Between winter storm surges - Human occupation on a growing Mid-Holocene transgression maximum (Tapes) beach ridge at Longva, Western Norway
Bondevik, Stein; Lødøen, Trond; Tøssebro, Christine; Årskog, Hanne Bente; Hjelle, Kari Loe; Mehl, Ingvild Kristine (Peer reviewed; Journal article, 2019-05-23)Substantial amounts of archaeological material have been found intermixed with beach pebbles and cobbles on the Tapes beach ridge at Longva on the island Flemsøya/Skuløya in Western Norway. The artefacts show that the beach ... -
Calendar year age estimates of Allerød - Younger Dryas sea-level oscillations at Os, western Norway
Lohne, Øystein S.; Bondevik, Stein; Mangerud, Jan; Schrader, Hans (Journal article, 2004)A detailed shoreline displacement curve documents the Younger Dryas transgression in western Norway. The relative sea-level rise was more than 9m in an area which subsequently experienced an emergence of almost 60 m. The ... -
Evidence for three North Sea tsunamis at the Shetland Islands between 8000 and 1500 years ago
Bondevik, Stein; Mangerud, Jan; Dawson, Sue; Dawson, Alastair; Lohne, Øystein S. (Journal article, 2005-08)Coastal fen- and lake deposits enclose sand layers that record at least three Holocene tsunamis at the Shetland Islands. The oldest is the well-known Storegga tsunami (ca 8100 cal yr BP), which at the Shetlands invaded ... -
Groundwater fluctuations during a debris flow event in western Norway - Triggered by rain and snowmelt
Bondevik, Stein; Sorteberg, Asgeir (Journal article; Peer reviewed, 2021)Pore pressure is crucial in triggering debris slides and flows. Here we present measurements of groundwater pore pressure and temperature recorded by a piezometer 1.6 m below the surface on a slope susceptible to debris ... -

Bondevik, Stein; Mangerud, Jan; Dawson, Sue; Dawson, Alastair; Lohne, Øystein S. (EOS : Transactions;Vol. 84, No.31, Journal article, 2003-08-05) -
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, ...
