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 ... -
Internal structure of a Himalayan debris-covered glacier revealed by borehole optical televiewing
(Journal article; Peer reviewed, 2023)Characterising the structures within glaciers can give unique insight into ice motion processes. On debris-covered glaciers, traditional structural glaciological mapping is challenging because the lower glacier is hidden ... -
A previously unidentified fault revealed by the February 25, 2022 (Mw 6.1) Pasaman Earthquake, West Sumatra, Indonesia
(Journal article; Peer reviewed, 2023)A destructive earthquake (Mw 6.1) struck Pasaman, West Sumatra, Indonesia, on 25 February 2022, resulting in at least 18 deaths and damage to 1765 buildings. Our relocated foreshock, mainshock, and aftershocks and their ... -
Spatial variability in topology, connectivity and permeability of deformation band networks: Insights from the Jurassic Entrada Sandstone, Utah
(Journal article; Peer reviewed, 2023)Networks of deformation bands have the potential to act as baffles to fluid flow, yet little work has been devoted to addressing their network properties, such as topology and connectivity. Motivated by this, we investigate ... -
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 ... -
A conjugate fault revealed by the destructive Mw 5.6 (November 21, 2022) Cianjur earthquake, West Java, Indonesia
(Journal article; Peer reviewed, 2023)On 21 November 2022, a destructive earthquake (Mw 5.6) struck Cianjur, West Java, Indonesia, resulting in at least 321 deaths, damage to 47,000 buildings, and economic losses of up to 7.7 trillion Indonesian Rupiahs (∼US ... -
Revised Storegga Slide reconstruction reveals two major submarine landslides 12,000 years apart
(Journal article; Peer reviewed, 2023)The Storegga Slide is the largest known exposed submarine landslide in the world, which triggered a tsunami that inundated the coasts of northern Europe ~8,150 years ago. Previous studies suggested the removal of 50–70 m ... -
Structure and metabolic potential of the prokaryotic communities from the hydrothermal system of Paleochori Bay, Milos, Greece
(Journal article; Peer reviewed, 2023)Introduction: Shallow hydrothermal systems share many characteristics with their deep-sea counterparts, but their accessibility facilitates their study. One of the most studied shallow hydrothermal vent fields lies at ... -
High-Resolution Magnetic-Geochemical Mapping of the Serpentinized and Carbonated Atlin Ophiolite, British Columbia: Toward Establishing Magnetometry as a Monitoring Tool for In Situ Mineral Carbonation
(Journal article; Peer reviewed, 2023)We address in situ serpentinization and mineral carbonation processes in oceanic lithosphere using integrated field magnetic measurements, rock magnetic analyses, superconducting quantum interference device (SQUID) microscopy, ... -
Leaving a plastic legacy: Current and future scenarios for mismanaged plastic waste in rivers
(Journal article; Peer reviewed, 2023)Mismanaged plastic waste (MPW) entering the riverine environment is concerning, given that most plastic pollution never reaches the oceans, and it has a severe negative impact on terrestrial ecosystems. However, significant ... -
Sensitivity of isochrones to surface mass balance and dynamics
(Journal article; Peer reviewed, 2023)The interior of an ice sheet consists of layers of accumulated snow, which contain important information on accumulation and ice dynamics that are imprinted on layer shapes over time. This work describes how changes in ... -
Geochemical and Isotopic Fractionation in the Hypogene Ore, Gossan, and Saprolite of the Alvo 118 Deposit: Implications for Copper Exploration in the Regolith of the Carajás Mineral Province
(Journal article; Peer reviewed, 2023)In the Carajás Mineral Province, gossan formation and lateritization have produced numerous supergene orebodies at the expense of IOCG deposits and host rocks. The Alvo 118 deposit comprises massive and disseminated hypogene ... -
Proterozoic Deep Carbon—Characterisation, Origin and the Role of Fluids during High-Grade Metamorphism of Graphite (Lofoten–Vesterålen Complex, Norway)
(Journal article; Peer reviewed, 2023)Graphite formation in the deep crust during granulite facies metamorphism is documented in the Proterozoic gneisses of the Lofoten–Vesterålen Complex, northern Norway. Graphite schist is hosted in banded gneisses dominated ... -
Hydrothermal activity fuels microbial sulfate reduction in deep and distal marine settings along the Arctic Mid Ocean Ridges
(Journal article; Peer reviewed, 2023)Microbial sulfate reduction is generally limited in the deep sea compared to shallower marine environments, but cold seeps and hydrothermal systems are considered an exception. Here, we report sulfate reduction rates and ... -
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 ... -
Stratigraphic expression of the Paleocene-Eocene Thermal Maximum climate event during long-lived transient uplift—An example from a shallow to deep-marine clastic system in the Norwegian Sea
(Journal article; Peer reviewed, 2023-02-20)Seismic geomorphology and stratigraphic analysis can reveal how source-to-sink systems dynamically respond to climatic and tectonic forcing. This study uses seismic reflection data from the Norwegian Sea to investigate the ... -
A new deglacial climate and sea-level record from 20 to 8 ka from IODP381 site M0080, Alkyonides Gulf, eastern Mediterranean
