Climate variability in the subarctic area for the last 2 millennia
(Peer reviewed; Journal article, 2018-01-25)To put recent climate change in perspective, it is necessary to extend the instrumental climate records with proxy data from paleoclimate archives. Arctic climate variability for the last 2 millennia has been investigated ... -
Climate, glacial and vegetation history of the Polar Ural Mountains since early MIS 2 inferred from a 54-m-long sediment core from Lake Bolshoye Shuchye
(Journal article; Peer reviewed, 2021)Because continuous and high-resolution records are scarce in the polar Urals, a multiproxy study was carried out on a 54 m long sediment succession (Co1321) from Lake Bolshoye Shchuchye. The sedimentological, geochemical, ... -
A climatic trigger for the giant Troll pockmark field in the northern North Sea
(Peer reviewed; Journal article, 2017-04)Pockmarks are seafloor craters usually formed during methane release on continental margins. However, the mechanisms behind their formation and dynamics remain elusive. Here we report detailed investigations on one of the ... -
Clinoform systems: Review and dynamic classification scheme for shorelines, subaqueous deltas, shelf edges and continental margins
(Peer reviewed; Journal article, 2018-10)Clinoforms are inclined and normally basinward-dipping horizons developed over a range of spatial and temporal scales in both siliciclastic and carbonatic systems. The study of clinoform successions underpins sequence ... -
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 as a new tool for reconstructing Miocene climate change
(Doctoral thesis, 2020-01-27)This PhD thesis focuses on the clumped isotope paleothermometer and its application to foraminiferal carbonates buried in ocean sediments. Based on new proxy evidence for ocean temperature, the thesis aims at improving our ... -
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 ... -
Clumped isotope thermometry in foraminifera - From calibration to Plio-Pleistocene temperature reconstructions in the Indo-Pacific Warm Pool
(Doctoral thesis, 2020-06-25)Clumped isotopes thermometry on foraminifera holds the potential to accurately reconstruct ocean temperatures on million-year timescales. In contrast to most other paleothermometers, clumped isotopes do not rely on prior ... -
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 ... -
A Comparative Palynofacies Study of Two Methods Used for Source Rock Validation. A Case Study From a Mississippian Succession on Spitsbergen
(Master thesis, 2017-06-30)This study is conducted on the analysis of twenty-nine kerogen slides of Tournasian and Visean age. The outcrop samples were collected from the Hoelbreen and Birger Johnsonfjellet Members in the Birger Johnsonfjellet section ... -
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 ... -
