Reconnaissance report and preliminary ground motion simulation of the 12 May 2008 Wenchuan earthquake
(Peer reviewed; Journal article, 2010)The Mw = 8.0Wenchuan earthquake of May 12, 2008, caused destruction over a wide area. The earthquake cost more than 69,000 lives and the damage is reported to have left more than 5 million people homeless. It is estimated ... -
Reconstructing early Holocene seasonal bottom-water temperatures in the northern North Sea using stable oxygen isotope records of Arctica islandica shells
(Journal article; Peer reviewed, 2021)The knowledge of seasonal temperature variability in the ocean is essential for understanding climate and its response to forcing factors. Time intervals with highly dynamic climate and increased seasonal forcing such as ... -
Reconstructing environmental variability at Leynavatn, Faroe Islands
(Master thesis, 2019-06-26)A new continuous environmental reconstruction has been established based on a 390 cm long lake core from Leynavatn Streymoy (southeast Faroes Islands), containing sediments spanning from the last 550 CE (Common Era). To ... -
Reconstructing Paleoflood Occurrence and Magnitude from Lake Sediments
(Journal article; Peer reviewed, 2022)Lake sediments are a valuable archive to document past flood occurrence and magnitude, and their evolution over centuries to millennia. This information has the potential to greatly improve current flood design and risk ... -
Reconstructing surface mass balance from the englacial stratigraphy of the Greenland Ice Sheet
(Doctoral thesis, 2022-09-30)Interiøren av isflakene består av mange lag akkumulert snø, hvis tykkelse avhenger av overflatemassebalanse (OMB) fra fortiden og effekten av dynamisk tynning etter lagenes avsetning. Denne oppgaven undersøker påvirkningen ... -
Reconstructing uplift signals from sediment supply and tectonostratigraphy in a clastic shelf, Early Paleogene Shetland Platform
(Doctoral thesis, 2024-06-25)Sedimentære bassenger er viktige arkiver for planetens geodynamikk og klima. Kompleksiteten til dette registeret innebærer dog at det er en ikke-triviell oppgave å ekstrahere tektoniske og klimatiske svingninger, noe som ... -
Reconstruction of changes in the Weddell Sea sector of the Antarctic Ice Sheet since the Last Glacial Maximum
(Peer reviewed; Journal article, 2014-09-15)A robust understanding of Antarctic Ice Sheet deglacial history since the Last Glacial Maximum is important in order to constrain ice sheet and glacial-isostatic adjustment models, and to explore the forcing mechanisms ... -
Reconstruction of glacier variability from lake sediments reveals dynamic Holocene climate in Svalbard
(Peer reviewed; Journal article, 2015-09-12)The Arctic is warming faster than anywhere else on Earth. Holocene proxy time-series are increasingly used to put this amplified response in perspective by understanding Arctic climate processes beyond the instrumental ... -
A reconstruction of Jostedalsbreen during the Little Ice Age and geometric changes to outlet glaciers since then
(Journal article; Peer reviewed, 2022)Mountain glaciers and ice caps are undergoing rapid mass loss but rates of present-day changes and models of future projections both lack long-term (centennial-scale) context. Here, we reconstruct the maximum glacier extent ... -
Record summer rains in 2019 led to massive loss of surface and cave ice in SE Europe
(Journal article; Peer reviewed, 2021)Glaciers worldwide are shrinking at an accelerated rate as the climate changes in response to anthropogenic influence. While increasing air temperature is the main factor behind glacier mass and volume loss, variable ... -
Record-breaking height for 8000-Year-Old tsunami in the North Atlantic

Reduced El Niño variability in the mid-Pliocene according to the PlioMIP2 ensemble
(Journal article; Peer reviewed, 2021)The mid-Pliocene warm period (3.264–3.025 Ma) is the most recent geological period during which atmospheric CO2 levels were similar to recent historical values (∼400 ppm). Several proxy reconstructions for the mid-Pliocene ... -
Reducing Uncertainties in Carbonate Clumped Isotope Analysis Through Consistent Carbonate-Based Standardization
(Peer reviewed; Journal article, 2018)About a decade after its introduction, the field of carbonate clumped isotope thermometry is rapidly expanding because of the large number of possible applications and its potential to solve long‐standing questions in Earth ... -
Refining benthic foraminiferal Mg/Ca-temperature calibrations using core-tops from the western tropical Atlantic: Implication for paleotemperature estimation
(Peer reviewed; Journal article, 2013-04)Benthic foraminiferal Mg/Ca has been shown to have great potential as a proxy for reconstructing deep water temperatures. However, the exact relationship between Mg uptake in benthic foraminifera and temperature is still ... -
Refining Greenland geothermal heat flux through stable isotope analysis
(Master thesis, 2023-03-30)Geothermal heat flux is an important control on the dynamics of glaciers and ice sheets. In Greenland however, only few direct observations of geothermal heat flux exist. The exact spatial distribution and magnitude of ... -
Regional correlation and seismic stratigraphy of Triassic Strata in the Greater Barents Sea: implications for sediment transport in Arctic basins
(Journal article; Peer reviewed, 2020)The Greater Barents Sea Basin (GBSB) in Arctic Russia and Norway is an intracratonic basin that accommodated an enormous amount of sediment during the Triassic. These deposits are up to 4.5 km thick over an area 2,500,000 ... -
