On the estimation of ice volume of alpine glaciers

Лëд и снег, 2015
Volume (V) − area (S) scaling approach (V = kSp, where V and S are obtained from direct measurements) is widely used for ice storage assessments in glacier-mountain systems.

Mountain glaciers under a changing climate [PDF]

Geology Today, 2018
Mountain glaciers are found around the world in ranges such as the Himalaya, the Andes and the European Alps. The majority of mountain glaciers world‐wide are shrinking. However, the rugged alpine topography through which these glaciers flow governs their dynamics and impacts on the regional climate systems that modify glacier mass balance. As a result,

Using dendroclimatic analysis of exotic deciduous conifers in an arboretum to document tree growth in response to climate change, Northeast Ohio, USA

PLANTS, PEOPLE, PLANET, EarlyView.
Rising temperatures and wetter conditions in the Midcontinent of North America are influencing climate responses in trees. Dendroclimatological analyses of four exotic deciduous conifer species from Secrest Arboretum, Northeast Ohio help identify past, present and future climate‐tree interactions.

Turbulent snow transport and accumulation: New reduced‐order models and diagnostics

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Our new reduced‐order models of snow particle transport provide high‐fidelity calculations of snow accumulation in turbulent flows at significantly reduced computational costs. Additional accumulation diagnostics from the reduced‐order model predict complex patterns of particle concentration in turbulent boundary layers via coherent flow structures in ...

The Transboundary Reach of the Columbia River: Cottonwood Colonization Followed Flow Moderation From the Columbia River Treaty Dams

River Research and Applications, EarlyView.
ABSTRACT The Columbia river provides the largest Pacific outflow in the Western Hemisphere and the greatest hydropower production of any North American river system. For hydropower generation and flood risk management, four massive water storage reservoirs followed the Columbia River Treaty between Canada and the United States, with three Canadian dams,

Identification of initial vegetation and habitat changes in small temperate fens using remote sensing

Remote Sensing in Ecology and Conservation, EarlyView.
Temperate fens with only incipient, subtle signs of deterioration can be reliably identified using Sentinel‐2 and aerial imagery, which sensitively detect early productivity‐related structural changes. Abstract Small temperate fens rank among the most endangered habitats in temperate Europe.

Propagation patterns of hydrological droughts in the source region of Yellow River: Insights from standardized versus threshold‐based approaches

River, EarlyView.
Abstract Understanding the propagation patterns of hydrological droughts is crucial for drought prevention, disaster mitigation, and water resource management. Two common methodological frameworks are employed: standardized indices, represented by the Standardized Streamflow Index (SSI), and threshold‐based (non‐standardized) indices, represented by ...

Geospatial technology based evaluation of recent morphodynamic changes and flow patterns in the upper Jhelum River

River, EarlyView.
Abstract This study was conducted to address the concerns over the changes in river morphology and their implications for sustainable river management. It investigates the morphological dynamics of the Upper Jhelum River between 2018 and 2023, using high‐resolution Sentinel‐2 imagery and advanced geospatial techniques to capture subtle yet significant ...

Mountain glaciers caught on camera

Eos, Transactions American Geophysical Union, 2011
Many glaciers around the world are melting, and new research is showing some of the dramatic details. Ulyana Horodyskyj, a graduate student at the Cooperative Institute for Research in Environmental Sciences (CIRES), University of Colorado at Boulder, set up cameras to take time‐lapse photographs of three lakes on a glacier in Nepal.
