A regional spatiotemporal analysis of large magnitude snow avalanches using tree rings [PDF]
Natural Hazards and Earth System Sciences, 2021 Snow avalanches affect transportation corridors and settlements worldwide. In many mountainous regions, robust records of avalanche frequency and magnitude are sparse or non-existent.

Direct measurement of optical properties of glacier ice using a photon-counting diffuse LiDAR [PDF]
, 2022 The production of meltwater from glacier ice, which is exposed at the margins of land ice during the summer, is responsible for a large proportion of glacier mass loss. The rate of meltwater production from glacier ice is especially sensitive to its physical structure and chemical composition which combine to determine the albedo of glacier ice ...

Species conflict at Earth’s edges – Contests, climate, and coveted resources
Frontiers in Ecology and Evolution, 2022 Direct conflict between species is an infrequently witnessed biological phenomenon. Potential drivers of such contests can include climate change, especially at Earth’s high elevation and latitudinal extremes where temperatures warm 2–5 times faster than

AMD-HookNet for Glacier Front Segmentation [PDF]
, 2023 Knowledge on changes in glacier calving front positions is important for assessing the status of glaciers. Remote sensing imagery provides the ideal database for monitoring calving front positions, however, it is not feasible to perform this task manually for all calving glaciers globally due to time-constraints.

Effect of Soil Environment on Species Diversity of Desert Plant Communities
Plants, 2023 Desert ecosystems possess an astonishing biodiversity and are rich in endangered species. This study investigated characteristics of species diversity and soil environmental factors in three major deserts of China’s Alxa Plateau. The Alxa Desert included

Evaluating the impact of the Central Chile Mega Drought on debris cover, broadband albedo, and surface drainage system of a Dry Andes glacier [PDF]
, 2023 In recent years, Chile has experienced an extraordinary drought that has had significant impacts on both the livelihoods of people and the environment, including the Andean glaciers. This study focuses on analyzing the surface processes of Universidad Glacier, a benchmark glacier for the Dry Andes.

Calving on tidewater glaciers amplified by submarine frontal melting [PDF]
O'Leary, M. and Christoffersen, P.: Calving on tidewater glaciers
amplified by submarine frontal melting, The Cryosphere Discuss., 6,
3287-3316, 2012, 2012 While it has been shown repeatedly that ocean conditions exhibit an important control on the behaviour of grounded tidewater glaciers, modelling studies have focused largely on the effects of basal and surface melting. Here, a finite-element model of stresses near the front of a tidewater glacier is used to investigate the effects of frontal melting on

Worldwide version-controlled database of glacier thickness observations [PDF]
Earth System Science Data, 2020 Although worldwide inventories of glacier area have been coordinated internationally for several decades, a similar effort for glacier ice thicknesses was only initiated in 2013.
