Late-stage evolution of hypogene caves at Tyuya-Muyun (Kyrgyzstan): Quantitative insights from mineral deposits
(Journal article; Peer reviewed, 2024)The Tyuya-Muyun massif in SW Kyrgyzstan hosts a number of caves some of which contain Ra- and U-bearing minerals that were extensively mined in the early 20th century. Previous studies have suggested that the caves of the ... -
Nucleation-assisted microthermometry: A novel application to fluid inclusions in halite
(Journal article; Peer reviewed, 2024)Halite deposits have long been utilized for interrogating past climate conditions. Microthermometry on halite fluid inclusions has been used to determine ancient water temperatures. One notable obstacle in performing ... -
World-class amethyst-agate geodes from Los Catalanes, Northern Uruguay: genetic implications from fluid inclusions and stable isotopes
(Journal article; Peer reviewed, 2024)The amethyst and agate geodes from the Los Catalanes Gemmological District in Uruguay represent one of the main deposits of its kind worldwide. The geometry of the deposit is horizontal, with an irregular distribution of ... -
Geothermometry of calcite spar at 10–50 °C
(Journal article; Peer reviewed, 2024)Carbonate geothermometry is a fundamental tool for quantitative assessment of the geothermal and geochemical evolution of diagenetic and hydrothermal systems, but it remains difficult to obtain accurate and precise formation ... -
Temperature sensitivity of the mineral permafrost feedback at the continental scale
(Journal article; Peer reviewed, 2024)Oxidative weathering of sulfide minerals in sedimentary rocks releases carbon dioxide (CO2) into the atmosphere. In permafrost zones, this could be a positive feedback on climate change if it increases with warming, yet ... -
Evolution of Modern and Ancient Orogenic Belts

Ice thickness and bed topography of Jostedalsbreen ice cap, Norway
(Journal article; Peer reviewed, 2024)We present an extensive dataset of ice thickness measurements from Jostedalsbreen ice cap, mainland Europe's largest glacier. The dataset consists of more than 351 000 point values of ice thickness distributed along ∼ 1100 km ... -
Multiple late Holocene glacier advances on the sub-Antarctic Kerguelen (49°S) islands: evidence from a 1200 yr sediment core from a glacial threshold basin
(Journal article; Peer reviewed, 2024)Southern Ocean (SO) climate is rapidly changing because of global warming and regional climate feedback loops like shifts of the Southern Hemisphere (SH) westerly winds (SHW) and related Southern Annular Mode (SAM). Over ... -
Palaeogeography and 3D variability of a dynamically uplifted shelf: Observations from seismic stratigraphy of the Palaeocene East Shetland Platform
(Journal article; Peer reviewed, 2024)In the Palaeocene North Sea, pulses in turbidite fan deposition and shelfal progradation have been correlated with episodes of regional uplift caused by a precursor of the Icelandic Plume. In the East Shetland Platform, ... -
Eccentricity pacing and rapid termination of the early Antarctic ice ages
(Journal article; Peer reviewed, 2024)Earth’s obliquity and eccentricity cycles are strongly imprinted on Earth’s climate and widely used to measure geological time. However, the record of these imprints on the oxygen isotope record in deep-sea benthic ... -
High-resolution sediment mass-budget of the Shetland Platform during the Paleocene–Early Eocene; constraints on external forcing by uplift and climate
(Journal article; Peer reviewed, 2025)In the Paleocene–Early Eocene, distinct surface and stratigraphic signals recorded around Shetland have been correlated to hinterland uplift associated with the Icelandic Plume, the effects of the Paleocene–Eocene Thermal ... -
Refining Holocene sea-level variations for the Lofoten and Vesterålen archipelagos, northern Norway: implications for prehistoric human–environment interactions
(Journal article; Peer reviewed, 2024)The Lofoten and Vesterålen archipelagos are located off the outer coast of northern Norway far from the center of the former Fennoscandian Ice Sheet and near the continental shelf edge. Existing relative sea-level (RSL) ... -
Constraints on the Timing and Lower Crustal Accretion at the Schulz Massif, Mohns Ridge, Arctic Mid Ocean Ridges
(Journal article; Peer reviewed, 2024)The ultraslow-spreading Mohns Ridge is a key supersegment of the Arctic Mid-Ocean system, where it represents a boundary between the Jan Mayen hotspot in the south and the highly anomalous Knipovich Ridge to the north. ... -
A position and wave spectra dataset of Marginal Ice Zone dynamics collected around Svalbard in 2022 and 2023
(Journal article; Peer reviewed, 2024)Sea ice is a key element of the global Earth system, with a major impact on global climate and regional weather. Unfortunately, accurate sea ice modeling is challenging due to the diversity and complexity of underlying ... -
Preservation of Hydrothermal Fluid Copper Isotope Signatures in Chalcopyrite-Rich Chimneys: A Case Study From the PACMANUS Vent Field, Manus Basin
(Journal article; Peer reviewed, 2024)Copper isotopes (δ65Cu) in hydrothermal fluids have the potential to provide information on ore-forming processes occurring below the seafloor, but Cu isotope data from high-temperature fluids are scarce. Here, we examine ... -

Hydrochemical study of the desalinisation of quick clays in the Holocene at Tiller-Flotten, Norway
(Master thesis, 2025-01-08)The development of quick clays has been studied for over 50 years in Norway to evaluate and mitigate risk of quick clay landslides. One of the main remaining challenges is qualifying the spatial distribution of quick clays ... -
CO2 Leakage Risk through Remobilized Cenozoic Sediments in the Northern North Sea
(Master thesis, 2024-12-18)Climate change is one of the biggest challenges faced today. One of the possible solutions to mitigate this challenge is the secure storage of CO2 in the subsurface. Remobilized Cenozoic sediments contain large sand volumes ... -
The collapse of the Caledonian orogen in SW Norway: Insights from quartz textures
(Journal article; Peer reviewed, 2024)Extensional collapse is a common late-to post-collisional feature of orogens. It is particularly prominent in the SW Scandinavian Caledonides, where extensional detachments formed progressively from the initial reactivation ... -
Coastal lake sediments from Arctic Svalbard suggest colder summers are stormier
(Journal article; Peer reviewed, 2024)The Arctic is rapidly losing its sea ice cover while the region warms faster than anywhere else on Earth. As larger areas become ice-free for longer, winds strengthen and interact more with open waters. Ensuing higher waves ...
