Clitellate worms (Annelida) in late-glacial and Holocene sedimentary DNA records from the Polar Urals and northern Norway
(Peer reviewed; Journal article, 2018-11-26)While there are extensive macro‐ and microfossil records of a range of plants and animals from the Quaternary, earthworms and their close relatives amongst annelids are not preserved as fossils and therefore the knowledge ... -
Clumped isotope thermometry in bivalve shells: a tool for reconstructing seasonal upwelling
(Journal article; Peer reviewed, 2021)Carbonate clumped isotope thermometry is a powerful tool for reconstructing paleotemperature and paleosalinity. Despite its broad application in biotic and abiotic materials, its use in paleoclimate studies has been limited ... -
Coastal permafrost was massively eroded during the Bølling-Allerød warm period
(Journal article; Peer reviewed, 2023)The Bølling-Allerød interstadial (14,700–12,900 years before present), during the last deglaciation, was characterized by rapid warming and sea level rise. Yet, the response of the Arctic terrestrial cryosphere during this ... -
“Cold and wet” and “warm and dry” climate transitions at the East Asian summer monsoon boundary during the last deglaciation
(Journal article; Peer reviewed, 2022)Studies on millennial‒centennial abrupt climate events during the last deglaciation have significant relevance to modern-day abrupt and extreme climate changes that are occurring more frequently in the context of global ... -
Cold spells in the Nordic Seas during the early Eocene Greenhouse
(Journal article; Peer reviewed, 2020)The early Eocene (c. 56 - 48 million years ago) experienced some of the highest global temperatures in Earth’s history since the Mesozoic, with no polar ice. Reports of contradictory ice-rafted erratics and cold water ... -
Combination of Aerial, Satellite, and UAV Photogrammetry for Quantifying Rock Glacier Kinematics in the Dry Andes of Chile (30°S) Since the 1950s
(Journal article; Peer reviewed, 2021)The diachronic analysis of aerial and satellite imagery, uncrewed aerial vehicle (UAV) and in situ surveys obtained between 1956 and 2019 are employed to analyse landform surface kinematics for the Tapado site located in ... -
A community-based geological reconstruction of Antarctic Ice Sheet deglaciation 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 ... -
Comparative analysis defines a broader FMRFamide-gated sodium channel family and determinants of neuropeptide sensitivity
(Journal article; Peer reviewed, 2022)FMRFamide (Phe-Met-Arg-Phe-amide, FMRFa) and similar neuropeptides are important physiological modulators in most invertebrates, but the molecular basis of FMRFa activity at its receptors is unknown. We therefore sought ... -
Comparison between Air Temperature and Land Surface Temperature for the City of São Paulo, Brazil
(Journal article; Peer reviewed, 2022)This study aims to identify the relationship between changes in temperature regarding urbanization processes and seasonality in the city of São Paulo, located in the Tropic of Capricorn. The land surface temperature (LST) ... -
A comparison of ancient deltaic shoreline progradation with modern deltaic progradation rates: Unravelling the temporal structure of the shallow-marine Blackhawk Formation, Upper Cretaceous Western Interior Seaway, USA
(Journal article; Peer reviewed, 2022)Understanding how sedimentary rocks represent time is one of the significant challenges in sedimentology. Sedimentation rates retrieved from vertical sections are strongly timescale dependent, which means that we cannot ... -
A complex point-source solution of the acoustic eikonal equation for Gaussian beams in transversely isotropic media
(Peer reviewed; Journal article, 2020-03-11)The complex traveltime solutions of the complex eikonal equation are the basis of inhomogeneous plane-wave seismic imaging methods, such as Gaussian beam migration and tomography. We present the analytic approximations for ... -
Complex strain partitioning and heterogeneous extension rates during early rifting in the East Shetland Basin, northern North Sea
(Journal article; Peer reviewed, 2020)The early stages of continental rifting are accommodated by the growth of upper crustal normal fault systems that are distributed relatively evenly across the rift width. Numerous fault systems define fault arrays, the ... -
Compositions of dissolved organic matter in the ice-covered waters above the Aurora hydrothermal vent system, Gakkel Ridge, Arctic Ocean
(Journal article; Peer reviewed, 2022)Hydrothermal vents modify and displace subsurface dissolved organic matter (DOM) into the ocean. Once in the ocean, this DOM is transported together with elements, particles, dissolved gases and biomass along with the ... -
A conceptual geological model for offshore wind sites in former ice stream settings: The Utsira Nord site, North Sea
(Journal article; Peer reviewed, 2022)Conceptual geological models of the shallow subsurface that integrate geological and geotechnical information are important for more strategic data acquisition and engineering at offshore wind sites. Utsira Nord is an ... -
Configuration of the Scandinavian Ice Sheet in southwestern Norway during the Younger Dryas
(Journal article; Peer reviewed, 2023)The extent of the Scandinavian Ice Sheet in southwestern Norway is precisely located during the well-characterized Younger Dryas re-advance. However, the thickness of the ice sheet is less well constrained inland from the ... -
Consistent fluctuations in intermediate water temperature off the coast of Greenland and Norway during Dansgaard-Oeschger events
(Peer reviewed; Journal article, 2019-11-01)Rapid warmings epitomize the Dansgaard-Oeschger events that are recorded in Greenland ice cores and imprinted in ocean sediment cores. While the abrupt climate changes appear connected to perturbations in sea ice and ocean ... -
Constraining the 3-D Geometry of Fold-Thrust Belts Using Section Balancing vs. 3-D Interpolative Structural and Probabilistic Modeling
(Journal article, 2023)Quantitative uncertainty analysis, 2-D and 3-D modeling of the subsurface, as well as their visualization form the basis for decision making in exploration, nuclear waste storage and seismic hazard assessment. Methods such ... -
