Holocene multi-proxy environmental reconstruction from lake Hakluytvatnet, Amsterdamøya Island, Svalbard (79.5°N)
(Journal article, 2018-03)High resolution proxy records of past climate are sparse in the Arctic due to low organic production that restricts the use of radiocarbon dating and challenging logistics that make data collection difficult. Here, we ... -
Hunter-gatherer environments at the Late Pleistocene sites of Mwanganda's Village and Bruce, northern Malawi
(Journal article; Peer reviewed, 2022)Mwanganda's Village (MGD) and Bruce (BRU) are two open-air site complexes in northern Malawi with deposits dating to between 15 and 58 thousand years ago (ka) and containing Middle Stone Age (MSA) lithic assemblages. The ... -
Hydroclimate variability was the main control on fire activity in northern Africa over the last 50,000 years
(Journal article; Peer reviewed, 2022)North Africa features some of the most frequently burnt biomes on Earth, including the semi-arid grasslands of the Sahel and wetter savannas immediately to the south. Natural fires are fuelled by rapid biomass production ... -
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 ... -
An integrative geochronological framework for the Pleistocene So'a basin (Flores, Indonesia), and its implications for faunal turnover and hominin arrival
(Journal article; Peer reviewed, 2022)Flores represents a unique insular environment with an extensive record of Pleistocene fossil remains and stone artefacts. In the So'a Basin of central Flores these include endemic Stegodon, Komodo dragons, giant tortoises, ... -
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 ... -
A multiproxy approach to understanding the impact of the Storegga tsunami upon Mesolithic hunter-fisher-gatherers across different regions of western Norway
(Journal article; Peer reviewed, 2024)The Storegga tsunami (c. 8150 cal BP) is geologically well attested from various isolation basins across the west Norwegian coast. Ascertaining the impact it had upon the Mesolithic peoples who lived through it, however, ... -
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 ... -
Palaeoenvironmental and sea level changes during the Holocene in Eastern Saudi Arabia and their implications for Neolithic populations
(Journal article; Peer reviewed, 2020)This paper presents the key findings of a multidisciplinary study investigating the nature and timing of coastal landscape evolution in eastern Saudi Arabia during the Holocene. To date, most sea level reconstructions for ... -
Peptide mass fingerprinting as a tool to assess micromammal biodiversity in Pleistocene South Africa: The case of Klipdrift Shelter
(Journal article; Peer reviewed, 2023)Remains of small mammals from archaeological sites are often used as palaeoenvironmental proxies in the reconstruction of past environments. Yet, identification of micromammals to species-level based on morphological traits ... -
Plants, people and fire: Phytolith and FTIR analyses of the post-Howiesons Poort occupations at Border Cave (KwaZulu-Natal, South Africa)
(Journal article; Peer reviewed, 2023)Border Cave is a well-known South African Middle and Early Later Stone Age site located in KwaZulu-Natal. The site has exceptional plant preservation, unparalleled in the African Middle Stone Age archaeological record. ... -
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 ... -
