Ice-flow patterns and precise timing of ice sheet retreat across a dissected fjord landscape in western Norway
(Peer reviewed; Journal article, 2019-06)We reconstruct patterns of ice flow and retreat of the southwestern Scandinavian Ice Sheet, from 2900 field observations of glacial striae and elevation measurements of 60 ice-marginal-deltas from a high-resolution LiDAR ... -
Independent tephrochronological evidence for rapid and synchronous oceanic and atmospheric temperature rises over the Greenland stadial-interstadial transitions between ca. 32 and 40 ka b2k
(Journal article; Peer reviewed, 2020)Understanding the dynamics that drove past abrupt climate changes, such as the Dansgaard-Oeschger (DO) events, depends on combined proxy evidence from disparate archives. To identify leads, lags and synchronicity between ... -
Last Glacial Maximum environmental conditions at Andøya, northern Norway; evidence for a northern ice-edge ecological “hotspot”
(Journal article; Peer reviewed, 2020)Andøya on the NW coast of Norway is a key site for understanding the Last Glacial Maximum (LGM) in northern Europe. Controversy has arisen concerning the local conditions, especially about the timing and extent of local ... -
Late Glacial mountain glacier culmination in Arctic Norway prior to the Younger Dryas
(Journal article; Peer reviewed, 2020)Climate changes during the Late Glacial period (LG; 15-11 ka) as recorded in Greenland and Antarctic ice cores show a bipolar pattern. Between 14.5 ka and 13 ka ago, the northern latitudes experienced the Bølling/Allerød ... -
Late Plio-Pleistocene evolution of the Eurasian Ice Sheets inferred from sediment input along the northeastern Atlantic continental margin
(Journal article; Peer reviewed, 2022)High-latitude marine sediment archives may contain information about the configuration and dynamics of former ice sheets, paleoclimate and the intensity of glacial erosion and uplift in catchment areas. Compiling information ... -
NE Atlantic continental slope stability from a numerical modeling perspective
(Peer reviewed; Journal article, 2019-01)Trough mouth fans are environments characterized by high sediment supply during glacial stages and the occurrence of large-scale instabilities. The geological record indicates that several of these environments have failed ... -
A new deglacial climate and sea-level record from 20 to 8 ka from IODP381 site M0080, Alkyonides Gulf, eastern Mediterranean
(Journal article; Peer reviewed, 2023)Records of relative sea-level rise for the last deglaciation are mostly limited to coral reef records and geophysical model estimates, but observational data from regions with temperate climates is sparse. We present a new ... -
Present day Jakobshavn Isbræ close to the Holocene minimum extent
(Journal article; Peer reviewed, 2020)Marine terminating glaciers evolve on millenial timescales in response to changes in oceanic and atmospheric conditions. However, the relative role of oceanic and atmospheric drivers remains uncertain. The evolution of ... -
Rapid retreat of a Scandinavian marine outlet glacier in response to warming at the last glacial termination
(Journal article; Peer reviewed, 2020)Marine outlet glaciers on Greenland are retreating, yet it is unclear if the recent fast retreat will persist, and how atmosphere and ocean warming will impact future retreat. We show how a marine outlet glacier in ... -
Reconstruction of changes in the Weddell Sea sector of the Antarctic Ice Sheet 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 ... -
A reconstruction of Jostedalsbreen during the Little Ice Age and geometric changes to outlet glaciers since then
(Journal article; Peer reviewed, 2022)Mountain glaciers and ice caps are undergoing rapid mass loss but rates of present-day changes and models of future projections both lack long-term (centennial-scale) context. Here, we reconstruct the maximum glacier extent ... -
Review and test of reproducibility of subdecadal resolution palaeoenvironmental reconstructions from microfossil assemblages
(Peer reviewed; Journal article, 2019)Very high, even annual, resolution quantitative palaeoenvironmental reconstructions have been generated from microfossil assemblage data using transfer functions. Evidence of the utility of some of these reconstructions ... -
Sea ice variability in the North Atlantic subpolar gyre throughout the last interglacial
(Journal article; Peer reviewed, 2023)The Last Interglacial period, Marine Isotope Stage 5e (MIS 5e ∼116–128 ka), is thought to have had a warmer, but less stable climate than the present interglacial. One key factor that has the potential to influence the ... -
Sensitivity of coastal southern African climate to changes in coastline position and associated land extent over the last glacial
(Journal article; Peer reviewed, 2023)Paleoclimatic changes in South Africa, especially around the southern Cape region, are of intense interdisciplinary interest; as this is an important area in the context of human evolution, hosting several prominent ... -
Tephra horizons identified in the western North Atlantic and Nordic Seas during the Last Glacial Period: Extending the marine tephra framework
(Journal article; Peer reviewed, 2020)Geochemically distinct volcanic ash (tephra) deposits are increasingly acknowledged as a key geochronological tool to synchronize independent paleoclimate archives. Recent advances in the detection of invisible (crypto) ... -
Tracing the last remnants of the Scandinavian Ice Sheet: Ice-dammed lakes and a catastrophic outburst flood in northern Sweden
(Peer reviewed; Journal article, 2019-08-08)We present geomorphological evidence of large, previously undocumented, early Holocene ice-dammed lakes in the Scandinavian Mountains of northwestern Sweden. The lakes extents indicate that the last remnants of the ... -
Was common Era glacier expansion in the Arctic Atlantic region triggered by unforced atmospheric cooling?
(Peer reviewed; Journal article, 2019-08-05)The timing and causes of Common Era (CE) glacier growth in the Arctic Atlantic region remain elusive. There is mounting evidence of advances that predate the Little Ice Age (1250–1850 CE); this challenges the view that ...
