Permafrost and Periglacial Processes, EarlyView.ABSTRACT The McMurdo Dry Valleys, the largest ice‐free region in Antarctica, are home to a cold‐desert hydrologic system of glaciers, snowbanks, streams, and lakes. Freshwater is also stored as dead glacial ice, which is poorly constrained in terms of ion concentrations and interactions with both in situ and overlying sediments.

Calving speed and climatic sensitivity of New Zealand lake-calving glaciers [PDF]
Annals of Glaciology, 2003 AbstractCalving speeds and calving mechanisms in fresh water contrast with those in tidewater. We obtained calving speeds for six lake-calving glaciers in New Zealand’s Southern Alps, and surveyed the depths and temperatures of their ice-contact lakes. The glaciers are temperate, grounded in shallow (≤20 m) water, and exhibit compressive flow at their ...

Suitable habitat of Himalayan wolf in Upper Mustang, Annapurna Conservation Area, Nepal
Wildlife Biology, EarlyView.Decades ago, the Himalayan wolf Canis lupus chanco, a genetically distinct sub‐species of the gray wolf Canis lupus, faced persecution by local communities in the Nepalese Himalayas. Recently, wolf populations have returned and recolonized, sparking concerns about conflicts over livestock depredation, and emphasizing the urgent need for comprehensive ...

A 3D glacier dynamics–line plume model to estimate the frontal ablation of Hansbreen, Svalbard [PDF]
The CryosphereFrontal ablation is responsible for a large fraction of the mass loss from tidewater glaciers. The main contributors to frontal ablation are iceberg calving and submarine melting, with calving often being the largest.

Grounding line migration through the calving season at Jakobshavn Isbræ, Greenland, observed with terrestrial radar interferometry [PDF]
The Cryosphere, 2018 Ice velocity variations near the terminus of Jakobshavn Isbræ, Greenland, were observed with a terrestrial radar interferometer (TRI) during three summer campaigns in 2012, 2015, and 2016.

Integrative Zoology, EarlyView.The graphical abstract illustrates the comprehensive workflow of our study, from the deployment of infrared cameras at sites with high activity of four large carnivores, through data collection and assessment of activity patterns, to the prediction of time periods with potential human–large carnivore conflicts and the proposal of corresponding ...

High-frequency image analysis of calving activity and styles at Hansbreen, Svalbard
Journal of GlaciologySequential photographic records of glacier termini go back to the mid-20th century, revealing climate-driven retreat. More recently, time-lapse imagery has enabled detailed analysis of glacier dynamics, including calving.

A simple stress-based cliff-calving law [PDF]
The Cryosphere, 2019 Over large coastal regions in Greenland and Antarctica the ice sheet calves directly into the ocean. In contrast to ice-shelf calving, an increase in calving from grounded glaciers contributes directly to sea-level rise.

The Chaos Beneath a Glacier’s Calving Front
Eos, 2021 For the first time, researchers have captured continuous data on the abrupt changes and activities happening at a glacier’s calving front.

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.Abstract Antarctic Bottom Water (AABW) is a cold, dense water mass formed around Antarctica that ventilates the global abyssal ocean. Recent studies have reported widespread warming, freshening, and thinning of AABW, yet its temporal variability remains poorly constrained because of sparse observations.
