Revolution and Continuity? Reassessing Nineteenth-Century Moorland Reclamation Through Palaeoecological and Archival Research
(Taylor and Francis Group, 2023-08-10)The upland moorlands of Britain are environmentally and culturally important ecosystems. Yet, our understanding of historical attempts to ‘reclaim’ these landscapes is often based upon incomplete accounts of agricultural ... -
More than agriculture: analysing time-cumulative human impact on European land-cover of second half of the Holocene
(Elsevier, 2023-08-15)Assessment of past anthropogenic modifications of land-cover dynamics is key to understanding the human role in the Earth system. Recent advances in palaeoenvironmental sciences allow us to assess the long-term impacts ... -
Constraining the contribution of the Antarctic Ice Sheet to Last Interglacial sea-level
(American Association for the Advancement of ScienceUnited States, 2023-07-05)Polar temperatures during the Last Interglacial [LIG; ~129 to 116 thousand years (ka)] were warmer than today, making this time period an important testing ground to better understand how ice sheets respond to warming. However, ... -
Uniquely low stable iron isotopic signatures in deep marine sediments caused by Rayleigh distillation
(Springer Science and Business Media LLCEngland, 2023-06-24)Dissimilatory iron reduction (DIR) is suggested to be one of the earliest forms of microbial respiration. It plays an important role in the biogeochemical cycling of iron in modern and ancient sediments. Since microbial ... -
Global variability and controls on the accumulation of fallout radionuclides in cryoconite
(Elsevier BVNetherlands, 2023-06)The accumulation of fallout radionuclides (FRNs) from nuclear weapons testing and nuclear accidents has been evaluated for over half a century in natural environments; however, until recently their distribution and abundance ... -
Estimation of eruption source parameters for the 2021 La Soufrière eruption (St. Vincent): implications for quantification of eruption magnitude on volcanic islands
(The Geological Society, 2024-01-05)Eruption source parameters (ESPs) used to characterize explosive eruptions are estimated from tephra deposit data using different models (statistical or numerical) and inversion approaches. The ESPs thus derived are subject ... -
Phytoplankton responses to dust addition in the FeMn co-limited eastern Pacific sub-Antarctic differ by source region
(National Academy of SciencesUnited States, 2023-07-03)The seasonal availability of light and micronutrients strongly regulates productivity in the Southern Ocean, restricting biological utilization of macronutrients and CO2 drawdown. Mineral dust flux is a key conduit for ... -
Ocean circulation and biological processes drive seasonal variations of dissolved Al, Cd, Ni, Cu, and Zn on the Northeast Atlantic continental margin
(Elsevier BV, 2023-05-20)Nutrients and nutrient-like dissolved trace metals (dTMs) are essential for the functioning of marine organisms and therefore form an important part of ocean biogeochemical cycles. Here, we report on the seasonal distributions ... -
Modelling pyroclastic density currents of the April 2021 La Soufrière St. Vincent eruption: from rapid invasion maps to field-constrained numerical simulations
(Geological Society of London, 2024-04-01)<jats:title>Abstract</jats:title> <jats:p> The April 2021 La Soufrière of St. Vincent eruption generated several pyroclastic density currents (PDCs) during the two weeks of the crisis, from April 9 ... -
Holocene variations in the Asian Summer and Winter Monsoons reconstructed from extensive lacustrine sediments in the Mu Us Desert, northern China
(Elsevier BV, 2023-08-01)The Salawusu River Valley cuts through the Mu Us Desert in north central China, and lies at the interface of the East Asian Summer and Winter Monsoonal regions. Exposed at numerous locations in the valley side are extensive ...
