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 ... -
1D crustal structure of Albania region
(Journal article; Peer reviewed, 2023)A new crustal 1D layered model for Albania has been determined. The data used consist of P and S readings from 108 evenly distributed and well located earthquakes using the Albanian Seismic Network and nearby seismic ... -
The 2021 MW 6.2 Mamuju, West Sulawesi, Indonesia earthquake: partial rupture of the Makassar Strait thrust
(Journal article; Peer reviewed, 2023)On the 2021 January 15 (local date), an MW 6.2 earthquake struck the Mamuju and Majene regions of West Sulawesi, Indonesia. This event killed more than 100 inhabitants, leaving at least 30 000 people displaced from their ... -
3-D induction log modelling with integral equation method and domain decomposition pre-conditioning
(Journal article; Peer reviewed, 2024)The deployment of electromagnetic (EM) induction tools while drilling is one of the standard routines for assisting the geosteering decision-making process. The conductivity distribution obtained through the inversion of ... -
3-D seismic images of an extensive igneous sill in the lower crust
(Peer reviewed; Journal article, 2019-05-31)When continents rift, magmatism can produce large volumes of melt that migrate upwards from deep below the Earth’s surface. To understand how magmatism impacts rifting, it is critical to understand how much melt is generated ... -
The 30 June 2017 North Sea Earthquake: Location, Characteristics, and Context
(Journal article; Peer reviewed, 2020)The Mw 4.5 southern Viking graben earthquake on 30 June 2017 was one of the largest seismic events in the Norwegian part of the North Sea during the last century. It was well recorded on surrounding broadband seismic ... -
3D structure and formation of hydrothermal vent complexes at the paleocene-eocene transition, the Møre basin, MID-Norwegian margin
(Peer reviewed; Journal article, 2017-08)The mid-Norwegian margin is regarded as an example of a volcanic-rifted margin, formed prior to and during, Paleogene breakup of the northeast Atlantic. The area is characterized by the presence of voluminous basaltic ... -
Abiotic synthesis of methane and organic compounds in Earth’s lithosphere
(Journal article; Peer reviewed, 2020)Accumulation of molecular hydrogen in geologic systems can create conditions energetically favorable to transform inorganic carbon into methane and other organic compounds. Although hydrocarbons with a potentially abiotic ... -
Abrupt high-latitude climate events and decoupled seasonal trends during the Eemian
(Peer reviewed; Journal article, 2018-07-20)The Eemian (the Last Interglacial; ca. 129–116 thousand years ago) presents a testbed for assessing environmental responses and climate feedbacks under warmer-than-present boundary conditions. However, climate syntheses ... -
Acoustic waveform inversion for ocean turbulence
(Peer reviewed; Journal article, 2017)The seismic oceanography method is based on extracting and stacking the low-frequency acoustic energy scattered by the ocean heterogeneity. However, a good understanding on how this acoustic wavefield is affected by physical ... -
Aftershock study of the 2019 Ambon earthquake using moment tensor inversion: identification of fault reactivation in northern Banda, Indonesia
(Journal article; Peer reviewed, 2023)On September 26, 2019, an Mw 6.5 earthquake occurred 23 km northeast of Ambon City, Indonesia, followed by numerous aftershock series related to a complex fault network reactivation in the Ambon and Seram region. Using ... -
Alkaline sill intrusions in sedimentary basins: emplacement of the Mussentuchit Wash Sill in San Rafael Swell, Utah
(Journal article; Peer reviewed, 2022)Sills are important components of magmatic plumbing systems because of their role in magma storage. Previous studies have indirectly investigated sill propagation and architecture by using laboratory experiments, remote ... -
Alps to Apennines zircon roller coaster along the Adria microplate margin
(Peer reviewed; Journal article, 2018-02-09)We have traced the particle path of high-pressure metasedimentary rocks on Elba Island, Northern Apennines, with the help of a U-Pb-Hf detrital zircon study. One quarter of the analysed zircons are surprisingly young, ... -

Ambient noise levels and detection threshold in Norway
(Peer reviewed; Journal article, 2016-07)Ambient seismic noise is caused by a number of sources in specific frequency bands. The quantification of ambient noise makes it possible to evaluate station and network performance. We evaluate noise levels in Norway from ... -
Ammonia-oxidizing archaea have similar power requirements in diverse marine oxic sediments
(Journal article; Peer reviewed, 2021)Energy/power availability is regarded as one of the ultimate controlling factors of microbial abundance in the deep biosphere, where fewer cells are found in habitats of lower energy availability. A critical assumption ... -
Analysis of storm surge events along the Norwegian coast
(Journal article; Peer reviewed, 2023-02-08)Observed extreme sea levels are caused by a combination of extreme astronomical tide and extreme storm surge, or by an extreme value in one of these variables and a moderate value in the other. We analyzed measurements ... -
Anthropogenic and environmental drivers of vegetation change in southeastern Norway during the Holocene
(Journal article; Peer reviewed, 2021)Uncovering anthropogenic and environmental drivers behind past biological change requires integrated analyses of long-term records from a diversity of disciplines. We applied an interdisciplinary approach exploring effects ... -
Application of Clumped Isotope Thermometry to Benthic Foraminifera
