Holocene debris flows recognized in a lacustrine sedimentary succession: sedimentology, chronostratigraphy and cause of triggering
(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 ... -
Lineamenter Brudd og seismisitet i relasjon til grunnvann på Bømlo, Vestlandet
(Master thesis, 2003)Dette arbeidet er et resultat av feltarbeid på øygruppen Bømlo i Sunnhordland, Vestlandet, samt fjernanalyse av topo- og fotolineamenter, numeriske og analytiske modeller. En analyse av 389 topolineamenter viser en ... -
A study of rock lenses in extensional faults, focusing on factors controlling shapes and dimensions
(Master thesis, 2003)The intension of this work has been to investigate the factors controlling the shapes and dimensions of horses, including the type of mechanism active in their generation and development, position of the horses relative ... -

Pleistocene vertical carbon isotope and carbonate gradients in the South Atlantic sector of the Southern Ocean
(Peer reviewed; Journal article, 2003-01-10)We demonstrate that the carbon isotopic signal of mid-depth waters evolved differently from deep waters in the South Atlantic sector of the Southern Ocean during the Pleistocene. Deep sites (>3700 m) exhibit large ... -
Atlantic Ocean thermohaline circulation changes on orbital to suborbital timescales during the mid-Pleistocene
(Peer reviewed; Journal article, 2003-02-19)Mid-Pleistocene benthic ∂18O and ∂13C time series from the North Atlantic site 983 and Ceara Rise site 928 are compared to an array of existing isotopic records spanning the Atlantic basin and the geographic extremes of ... -
A Miocene (8–12 Ma) intermediate water benthic stable isotope record from the northeastern Atlantic, ODP Site 982
(Peer reviewed; Journal article, 2003-03-12)Oxygen and carbon isotope records are presented for the benthic foraminifer Cibicidoides wuellerstorfi from upper middle through lower upper Miocene (11.6–8.2 Ma) sediments recovered at intermediate water depth (1134 m) ... -
A high-resolution study of Holocene paleoclimatic and paleoceanographic changes in the Nordic Seas
(Peer reviewed; Journal article, 2003-03-26)High-resolution records from IMAGES core MD95-2011 in the eastern Norwegian Sea provide evidence for relatively large- and small-scale high-latitude climate variability throughout the Holocene. During the early and ... -
Theoretical equilibrium-line altitudes and glacier buildup sensitivity in southern Norway based on meteorological data in a geographical information system
(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 ... -
A theoretical approach to glacier equilibrium-line altitudes using meteorological data and glacier massbalance
(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 ... -
Late Holocene surface ocean conditions of the Norwegian Sea (Vøring Plateau)
(Peer reviewed; Journal article, 2003-06-04)Late Holocene sea surface ocean conditions of the eastern Norwegian Sea (Vøring Plateau) are inferred from planktic stable isotopes and planktic foraminiferal assemblage changes in cores JM97-948/2A and MD95-2011 (66.97°N, ... -
Record-breaking height for 8000-Year-Old tsunami in the North Atlantic

Deep sea sedimentary analogs for the Vostok ice core
(Peer reviewed; Journal article, 2003-08-07)Many applications of the Vostok ice core depend critically on the ability to make stratigraphic ties to marine records in the adjacent Southern Ocean. Here we present oxygen isotopic records from high accumulation rate ... -
A 1.3-Myr palaeoceanographic record from the continental margin off Dronning Maud Land, Antarctica
(Peer reviewed; Journal article, 2003-09-15)A 12.5 m long core was retrieved from the continental margin off Dronning Maud Land, Antarctica. Magnetostratigraphy, stable isotopes, 14C accelerator mass spectrometer and amino acid analyses indicate a continuous sediment ... -
Spring-summer temperature reconstruction in western Norway 1734-2003: a data-synthesis approach
(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 ... -
Calendar year age estimates of Allerød - Younger Dryas sea-level oscillations at Os, western Norway
(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 ... -
Environmental changes off North Iceland during the deglaciation and the Holocene: foraminifera, diatoms and stable isotopes
(Peer reviewed; Journal article, 2004-02)A combined study of foraminifera, diatoms and stable isotopes in marine sediments off North Iceland records major changes in sea surface conditions since about 15800 cal years (yr) BP. Results are presented from two gravity ... -
