Hydrological control of river and seawater lithium isotopes (2022)
Journal Article

Seawater lithium isotopes (δ7Li) record changes over Earth history, including a ∼9‰ increase during the Cenozoic interpreted as reflecting either a change in continental silicate weathering rate or weathering feedback strength, associated with tecton...

Journal Article

The Kula–Salihli UNESCO Geopark, western Turkey, is a tectonically and volcanically active region in which the most recent eruptions of basaltic lava, associated with scoria cone formation, were during the latest Pleistocene and the Holocene. Much ol... Read More about The Kula–Salihli UNESCO Geopark: Spectacular records of Quaternary volcanism, fluvial and landscape evolution and Quaternary environmental change.

Speaking Stata: The largest five - A tale of tail values (2022)
Journal Article

How do you work with the largest five, or smallest five, or any other fixed number of values in a tail of a distribution? In this column, I give examples of problems and code for basic calculations as a prelude to graphics, tables, and more detailed...

An investigation of the combined effect of rainfall and road cut on landsliding (2022)
Journal Article

The reduction of soil suction and consequent loss of shear strength due to infiltration is known to trigger shallow landslides during periods of concentrated rainfall. In the mountainous terrain of Nepal, the risk of shallow rainfall-induced landslid... Read More about An investigation of the combined effect of rainfall and road cut on landsliding.

Response of the East Antarctic Sheet to Past and Future Climate Change (2022)
Journal Article

The East Antarctic Ice Sheet contains the vast majority of Earth’s glacier ice (about 52 metres sea-level equivalent), but is often viewed as less vulnerable to global warming than the West Antarctic or Greenland ice sheets. However, some regions of... Read More about Response of the East Antarctic Sheet to Past and Future Climate Change.

The 853 CE Mount Churchill eruption: examining the potential climatic and societal impacts and the timing of the Medieval Climate Anomaly in the North Atlantic Region (2022)
Journal Article

The 852/3 CE eruption of Mount Churchill, Alaska, was one of the largest first-millennium volcanic events, with a magnitude of 6.7 (VEI 6) and a tephra volume of 39.4–61.9 km3 (95 % confidence). The spatial extent of the ash fallout from this event i...

Turbidity Currents Can Dictate Organic Carbon Fluxes Across River‐Fed Fjords: An Example From Bute Inlet (BC, Canada) (2022)
Journal Article

The delivery and burial of terrestrial particulate organic carbon (OC) in marine sediments is important to quantify, because this OC is a food resource for benthic communities, and if buried it may lower the concentrations of atmospheric CO2 over geo...

High spatial and temporal variability in Antarctic ice discharge linked to ice shelf buttressing and bed geometry (2022)
Journal Article

Antarctica’s contribution to global mean sea level rise has been driven by an increase in ice discharge into the oceans. The rate of change and the mechanisms that drive variability in ice discharge are therefore important to consider in the context... Read More about High spatial and temporal variability in Antarctic ice discharge linked to ice shelf buttressing and bed geometry.

Continuous measurements of valley floor width in mountainous landscapes (2022)
Journal Article

Mountainous landscapes often feature alluviated valleys that control both ecosystem diversity and the distribution of human populations. Alluviated, flat valley floors also play a key role in determining flood hazard in these landscapes. Various mech...

On the earliest Acheulean in Britain: first dates and in-situ artefacts from the MIS 15 site of Fordwich (Kent, UK) (2022)
Journal Article

Northern Europe experienced cycles of hominin habitation and absence during the Middle Pleistocene. Fluvial gravel terrace sites in the east of Britain and north of France provide a majority of the data contributing to this understanding, mostly thro...

Flake tools in the European Lower Paleolithic: A case study from MIS 9 Britain (2022)
Journal Article

Studies of flake tools in the British Lower Paleolithic are rare owing to lower quantities of flake tools than handaxes and the perception that flake tool technology became more important in the succeeding Middle Paleolithic. In Britain, and Europe m... Read More about Flake tools in the European Lower Paleolithic: A case study from MIS 9 Britain.

Resilience and Adaptation of Agricultural Practice in Neolithic Çatalhöyük, Turkey (2022)
Journal Article

Andrew Sherratt’s ‘Water, soil and seasonality’, World Archaeology (1980), signposted a long-term debate surrounding early farming adaptations to riverine landscapes in western Asia and Europe. Recent research at Çatalhöyük in central Anatolia, a key... Read More about Resilience and Adaptation of Agricultural Practice in Neolithic Çatalhöyük, Turkey.

Metals, mines and moorland: the changing lead mining landscapes of the North Pennines, UK, 1700-1948 (2022)
Journal Article

Intensive metal mining considerably altered many British upland landscapes between the 18th and 20th centuries, modifying both subterranean and surface environments and fundamentally changing the character of local settlements, infrastructure and soc...

Reproducibility and variability of earthquake subsidence estimates from saltmarshes of a Cascadia estuary (2022)
Journal Article

We examine fossil foraminiferal assemblages from 20 sediment cores to assess sudden relative sea-level (RSL) changes across three mud-over-peat contacts at three salt marshes in northern Humboldt Bay, California (~44.8°N, −124.2°W). We use a validate... Read More about Reproducibility and variability of earthquake subsidence estimates from saltmarshes of a Cascadia estuary.

A multiproxy approach to long-term herbivore grazing dynamics in peatlands based on pollen, coprophilous fungi and faecal biomarkers (2022)
Journal Article

Herbivory plays a significant role in regulating many contemporary terrestrial plant ecosystems, but remains an imperfectly understood component of past ecosystem dynamics because the diagnostic capability of methods is still being tested and refined...

First source-to-sink monitoring shows dense head controls sediment flux and runout in turbidity currents (2022)
Journal Article

Until recently, despite being one of the most important sediment transport phenomena on Earth, few direct measurements of turbidity currents existed. Consequently, their structure and evolution were poorly understood, particularly whether they are de...

Large interannual variability in supraglacial lakes around East Antarctica (2022)
Journal Article

Antarctic supraglacial lakes (SGLs) have been linked to ice shelf collapse and the subsequent acceleration of inland ice flow, but observations of SGLs remain relatively scarce and their interannual variability is largely unknown. This makes it diffi... Read More about Large interannual variability in supraglacial lakes around East Antarctica.

The role of geomorphology in the Quaternary (2021)
Journal Article

The advances in understanding of Quaternary geomorphology in the latter half of the twentieth century were closely linked with the improved knowledge of Quaternary climatic fluctuation, principally derived from isotopic evidence from ocean and ice co...

Near‐Bed Structure of Sediment Gravity Flows Measured by Motion‐Sensing “Boulder‐Like” Benthic Event Detectors (BEDs) in Monterey Canyon (2022)
Journal Article

The near-bed section of submarine gravity flows travels at the highest and most destructive speeds making direct measurements of this region of the flow difficult. Here results are presented from “boulder-like” Benthic Event Detectors (BEDs) that mea...
