Journal Article

The COVID-19 pandemic is an evolving urban crisis. This research paper assesses impacts of the lockdown on food security and associated coping mechanisms in two small cities in Bangladesh (Mongla and Noapara) during March to May 2020. Due to restrict... Read More about Contextualizing the COVID-19 pandemic’s impact on food security in two small cities in Bangladesh.

The transport and mass balance of fallout radionuclides in Brotherswater, Cumbria (UK) (2019)
Journal Article

This paper investigates the role of intervening transport processes on lake sediment records of the atmospherically deposited radionuclides 210Pb and 137Cs. Brotherswater is of particular interest to this issue in that its large catchment/lake area r...

The Falkland Islands palaeoecological response to millennial scale climate perturbations during the Pleistocene-Holocene transition: implications for future vegetation stability in Southern Ocean islands (2019)
Journal Article

Oceanic island flora is vulnerable to future climate warming, which is likely to promote changes in vegetation composition, and invasion of non‐native species. Sub‐Antarctic islands are predicted to experience rapid warming during the next century; t...

Preservation of organic carbon during active fluvial transport and particle abrasion (2019)
Journal Article

Oxidation of particulate organic carbon (POC) during fluvial transit releases CO2 to the atmosphere and can influence global climate. Field data show large POC oxidation fluxes in lowland rivers; however, it is unclear if POC losses occur predominant...

Time-Series Study of Associations between Rates of People Affected by Disasters and the El Niño Southern Oscillation (ENSO) Cycle (2019)
Journal Article

The El Niño Southern Oscillation (ENSO) is a major driver of climatic variability that can have far reaching consequences for public health globally. We explored whether global, regional and country-level rates of people affected by natural disasters...

The importance of riparian plant orientation in river flow: implications for flow structures and drag (2019)
Journal Article

In a series of high resolution numerical modelling experiments, we incorporated submerged riparian plants into a computational fluid dynamics (CFD) model used to predict flow structures and drag in river flow. Individual plant point clouds were captu... Read More about The importance of riparian plant orientation in river flow: implications for flow structures and drag.

An evaluation of a low-cost pole aerial photography (PAP) and structure from motion (SfM) approach for topographic surveying of small rivers (2019)
Journal Article

To better understand fluvial forms and processes, geomorphologists have a need for high-resolution fluvial topographic surveys. Continuous data collection approaches such as airborne laser scanning (ALS), terrestrial laser scanning (TLS), and structu...

Widespread distribution of supraglacial lakes around the margin of the East Antarctic Ice Sheet (2019)
Journal Article

Supraglacial lakes are important to ice sheet mass balance because their development and drainage has been linked to changes in ice flow velocity and ice shelf disintegration. However, little is known about their distribution on the world’s largest i... Read More about Widespread distribution of supraglacial lakes around the margin of the East Antarctic Ice Sheet.

Detection of channel-hillslope coupling along a tectonic gradient (2019)
Journal Article

Landscape morphology reflects the spatial and temporal history of erosion. Erosion in turn embodies the competition between tectonic and climatic processes. Quantitative analysis of topography can therefore reveal the driving tectonic conditions that... Read More about Detection of channel-hillslope coupling along a tectonic gradient.

How concave are river channels? (2018)
Journal Article

How does grid-resolution modulate the topographic expression of geomorphic processes? (2016)
Journal Article

In many locations, our ability to study the processes which shape the Earth are greatly enhanced through the use of high-resolution digital topographic data. However, although the availability of such datasets has markedly increased in recent years,... Read More about How does grid-resolution modulate the topographic expression of geomorphic processes?.

Monsoonal control on a delayed response of sedimentation to the 2008 Wenchuan earthquake (2019)
Journal Article

Infrequent extreme events such as large earthquakes pose hazards and have lasting impacts on landscapes and biogeochemical cycles. Sediments provide valuable records of past events, but unambiguously identifying event deposits is challenging because...

Spatial variation of groundwater response to multiple drivers in a depleting alluvial aquifer system, northwestern India (2019)
Journal Article

Unsustainable exploitation of groundwater in northwestern India has led to extreme but spatially variable depletion of the alluvial aquifer system in the region. Mitigation and management of groundwater resources require an understanding of the drive...

Reconstructions of Antarctic topography since the Eocene–Oligocene boundary (2019)
Journal Article

Accurate models of past Antarctic ice sheet behaviour require realistic reconstructions of the evolution of bedrock topography. However, other than a preliminary attempt to reconstruct Antarctic topography at the Eocene–Oligocene boundary, the long-t...

Quantifying the three‐dimensional stratigraphic expression of cyclic steps by integrating seafloor and deep‐water outcrop observations (2020)
Journal Article

Deep‐water deposits are important archives of Earth’s history including the occurrence of powerful flow events and the transfer of large volumes of terrestrial detritus into the world’s oceans. However the interpretation of depositional processes and...

Inception of a global atlas of sea levels since the Last Glacial Maximum (2019)
Journal Article

Determining the rates, mechanisms, and geographic variability of relative sea-level (RSL) change following the Last Glacial Maximum (LGM) provides insight into the sensitivity of ice sheets to climate change, the response of the solid Earth and gravi...

Linking Direct Measurements of Turbidity Currents to Submarine Canyon-Floor Deposits (2019)
Journal Article

Submarine canyons are conduits for episodic and powerful sediment density flows (commonly called turbidity currents) that move globally significant amounts of terrestrial sediment and organic carbon into the deep sea, forming some of the largest sedi...

Flexural rigidity and shoot reconfiguration determine wake length behind saltmarsh vegetation patches (2019)
Journal Article

Vegetation patches play an important role in controlling sediment deposition in shallow aquatic environments such as coastal saltmarshes and fluvial systems.

Very large convergent multi-fluted glacigenic deposits in the NW Highlands, Scotland (2019)
Journal Article

We describe two large convergent multi-fluted glacigenic deposits in the NW Highlands, Scotland, and point out their resemblance to a number of landforms emerging from presently deglaciating areas of Greenland and Antarctica. We suggest that they all... Read More about Very large convergent multi-fluted glacigenic deposits in the NW Highlands, Scotland.
