Holocen rekonstruksjon av Kongsbreen, Svalbard
(Master thesis, 2019-06-26)Dette masterprosjektet har ved bruk av innsjøsedimenter og kvartærgeologisk kartlegging rekonstruert posisjonen til brefronten til Kongsbreen gjennom holocen. Studien er basert på en sedimentkjerne fra Sarsvatnet, nordvest ... -
Holocene avsetningsprosesser i Fjærlandsfjorden basert på marine data
(Master thesis, 2019-06-08)Sedimentbassenger i vestnorske fjorder utgjør et viktig arkiv for å rekonstruere avsetningsmiljø og pre-historisk skredaktivitet samtidig som det gir et indirekte innblikk i hvordan klima har endret seg. I dette studiet ... -
Holocene changes in atmospheric circulation recorded in the oxygen-isotope stratigraphy of lacustrine carbonates from northern Sweden
(Peer reviewed; Journal article, 2002)The oxygen-isotope composition of local precipitation (d18OP) is reconstructed from carbonate lake-sediment components in a sediment core covering the last 10000 calendar years from Lake Tibetanus, a small, hydrologically ... -
Holocene climatic change reconstructed from diatoms, chironomids, pollen and near-infrared spectroscopy at an alpine lake (Sjuodjijaure) in northern Sweden
(Peer reviewed; Journal article, 2001)The results of a multiproxy study reconstructing the climate history of the last 9300 years in northern Sweden are presented. It is based on diatom, chironomid and pollen analyses, as well as near-infrared spec troscopy ... -
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 ... -
Holocene environmental and climate history of Trettetjørn, a low-alpine lake in Western Norway, based on subfossil pollen, diatoms, oribatid mites, and plant macrofossils
(Peer reviewed; Journal article, 2006)Holocene lake and catchment environmental history and regional climate are reconstructed from lake sediments at Trettetjørn, a small lake situated close to the present-day treeline in western Norway. Sediments began to ... -
Holocene fire and vegetation dynamics in the Central Pyrenees (Spain)
(Journal article; Peer reviewed, 2020)Fire-vegetation relationships are critical to understand transient mountain ecosystems and their long-term landscape dynamics, which is essential for alpine forest conservation. In this paper we aim to (1) reconstruct the ... -
Holocene forest development and tree-limit changes in Ridalen, in the Røros mountains
(Master thesis, 2010-07-02)Holocene forest development, tree migration and tree-line fluctuations have been reconstructed from peat sequences, derived from two study localities situated along an altitudinal transect between the north boreal and low ... -
Holocene forvitringsrater på fjelloverflater i Hereiane, Hardanger
(Master thesis, 2016-05-28)The Schmidt hammer has been used for relative dating for several decades. In the recent years scientists have approached the study field from a different angle, trying to set up a calibrated dating curve by using the ... -
Holocene glacier variability and Neoglacial hydroclimate at Ålfotbreen, western Norway
(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 ... -
HOLOCENE MARINGEOLOGISKE PROSESSER I SØRFJORDEN, OSTERØY
(Master thesis, 2022-03-07)De vestnorske fjordbassengene inneholder høytoppløselige arkiver som kan brukes for å studere og rekonstruere avsetningsmiljøet i fjordene. I dette studiet har de holocene avsetningsprosessene i den østlige delen av ... -
Holocene mean July temperature and winter precipitation in western Norway inferred from palynological and glaciological lake-sediment proxies
(Peer reviewed; Journal article, 2005)Reconstructions of mean July temperature (Tjul) and winter precipitation (Pw) for the last 11/500 years on the Folgefonna peninsula are presented. Tjul was reconstructed using pollen-climate transfer functions and Pw was ... -
Holocene multi-proxy environmental reconstruction from lake Hakluytvatnet, Amsterdamøya Island, Svalbard (79.5°N)
(Journal article, 2018-03)High resolution proxy records of past climate are sparse in the Arctic due to low organic production that restricts the use of radiocarbon dating and challenging logistics that make data collection difficult. Here, we ... -
Holocene palaeoclimate reconstructions at Vanndalsvatnet, western Norway, with particular reference to the 8200 cal. yr BP event
(Peer reviewed; Journal article, 2006)Analyses of organic content, magnetic susceptibility, grain size and pollen in sediments from the proglacial lake Vanndalsvatnet in western Norway provide a high-resolution terrestrial record and pollenbased quantitative ... -
