Proximity to active volcanoes enhances glacier velocity

Communications Earth & Environment
AbstractVolcanic heating is predicted by theory to affect the velocity of nearby glaciers. However, conclusive studies on a large scale are lacking. Here, we conduct a global comparison of the velocities of glaciers near active volcanoes (i.e. within 5 km) and those located elsewhere ( > 5 km from an active volcano).

Multiproxy Chronologies of the Hurd Rock Glacier (Livingston Island, South Shetland Islands, Maritime Antarctica): Between the Late‐Stage Stabilization and Flow Deceleration

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The Hurd Rock Glacier, located on Livingston Island (South Shetland Islands archipelago, Maritime Antarctica), is a tongue‐shaped feature composed of angular boulders, displaying transverse ridges and furrows, and featuring lobate structures, which are more prominently developed in its frontal sector.

Processes of crevasse formation and the dynamics of calving glaciers : a study at Breiđamerkurjökull

, 2009
A new model proposed by Benn et al. (2006, 2007) explains the dynamics of calving glaciers based on a new sliding law and a calving criterion modified from a crevasse depth model. In this thesis three key elements of this model are tested: 1) the role

Evaluating Testability of Permafrost Models Through Physical and Thermal Testing in Complex Mountain Terrain, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.

Animating blossom: Time‐lapse to encourage plant awareness in the YouTube era

PLANTS, PEOPLE, PLANET, EarlyView.
Time‐lapse videos can effectively capture key traits of flower blossoms, such as color, 3D structure, and temporal changes, making them valuable complements to herbarium specimens and other botanical collections. Despite the abundance of such videos on YouTube, most provide no ecological and botanical insights.

Activating Paper Applying Gelatin, Starch and Chitosan Coatings Loaded With O/W Emulsions Encapsulating Rutin, Carvacrol and α‐Tocopherol

Packaging Technology and Science, EarlyView.
Emulsion type governed the microstructure and functionality of papers coated with biopolymers matrix loaded with hydrophobic bioactives encapsulated into O/W emulsions. Emulsified systems improved UV–Vis barrier and antioxidant activity, whereas gelatin coatings with conventional or Pickering emulsions provided the greatest mechanical reinforcement ...

Towards improving Arctic mixed‐phase cloud representation in the ECMWF model using MOSAiC observations

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Abstract The presence of Arctic clouds plays a crucial role in the evolution of the surface temperature of Arctic sea ice. However, large biases in cloud representation remain in state‐of‐the‐art weather and climate models. In this study, we use observational data from the one‐year Arctic ship campaign Multi‐disciplinary drifting Observatory for the ...

Distinct characteristics and mechanisms of two tidewater glaciers exhibiting velocity anomalies in western Svalbard

GIScience & Remote Sensing
Svalbard hosts numerous tidewater glaciers whose dynamic responses are critical to polar environmental change and global sea-level rise. This study investigates Tunabreen glacier and Osbornebreen glacier in Svalbard using multi-source remote sensing data

WAVES OF ACCELERATED MOTION IN A GLACIER APPROACHING SURGE: THE MINI-SURGES OF

, 2014
. Periods of dramatically accelerated motion, in which the flow velocity increases suddenly from about 55 cm/d to a peak of 100-300 cm/d and then decreases gradually over the course of a day, occurred repeatedly during June and July 1978-81 in Variegated
