Hydrothermal Plume Fallout, Mass Wasting, and Volcanic Eruptions Contribute to Sediments at Loki's Castle Vent Field, Mohns Ridge
(Journal article; Peer reviewed, 2024)Sediments surrounding hydrothermal vents are important transition spaces between hydrothermal and pelagic environments. These sediments accumulate through diverse processes that include water column plume fallout, volcanic ... -
Data Management in Distributed, Federated Research Infrastructures: The Case of EPOS
(Journal article; Peer reviewed, 2024)Data management is a key activity when Open Data stewardship through services complying with the FAIR principles is required, as it happens in many National and European initiatives. Existing guidelines and tools facilitate ... -
Mineral composition and fluid inclusion characteristics of the extinct Deep Insight Hill seafloor massive sulfide deposit, Mohns Ridge
(Master thesis, 2024-12-18)Deep Insight Hill (72°49 ́N, 1°5 ́E) is a newly discovered extinct hydrothermal system located in the central part of the Mohns Ridge, the Arctic Mid Ocean Ridges. The deposit has been interpreted to be located on top of, ... -
Increasing seasonal variation in the extent of rivers and lakes from 1984 to 2022
(Journal article; Peer reviewed, 2024)Knowledge of the spatial and temporal distribution of surface water is important for water resource management, flood risk assessment, monitoring ecosystem health, constraining estimates of biogeochemical cycles and ... -
Design and performance of ELSA v2.0: an isochronal model for ice-sheet layer tracing
(Journal article; Peer reviewed, 2024)We provide a detailed description of the ice-sheet layer age tracer Englacial Layer Simulation Architecture (ELSA) – a model that uses a straightforward method to simulate the englacial stratification of large ice sheets ... -
Investigation of the 2010 rock avalanche onto the regenerated glacier Brenndalsbreen, Norway
(Journal article; Peer reviewed, 2024)Rock avalanches onto glaciers are rare in Norway. Here, we examine a rock avalanche that spread onto the regenerated Brenndalsbreen, an outlet glacier from Jostedalsbreen ice cap. The rock avalanche is intriguing in that ... -
Microseismicity Around Loki's Castle Hydrothermal Vent Field Reveals the Early Stages of Detachment Faulting at the Mohns-Knipovich Ridge Intersection
(Journal article; Peer reviewed, 2024)At slow to ultraslow spreading ridges, the limited melt supply results in tectonic accretion and the exhumation of mantle rocks. Melt supply is focused toward volcanic centers where magmatic accretion dominates. In areas ... -
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 ... -
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 ... -
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 ... -
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 ... -
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) ...
