The origin of green icebergs in Antarctica [PDF]

, 1992
A comparison of samples from a translucent green iceberg with a core from the Ronne Ice Shelf revealed an excellent agreement in isotopic composition, crystal structure, and incorporated sediment particles.

Basal Melting Variability of the Ross Ice Shelf From Mixing Ratios of Simulated Water Masses (1993–2018) and Potential Climatic Drivers

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Several water masses circulate under the Ross Ice Shelf (RIS), the largest ice shelf in Antarctica, each causing basal melting with a specific spatio‐temporal pattern. To investigate these patterns and their variability, we applied a mixing ratio analysis to simulated water masses from a new numerical ocean model of the Ross Sea.

The 'footloose' mechanism: iceberg decay from hydrostatic stresses [PDF]

, 2014
We study a mechanism of iceberg breakup that may act together with the recognized melt and wave-induced decay processes. Our proposal is based on observations from a recent field experiment on a large ice island in Baffin Bay, East Canada.

DeepRec: Global Terrestrial Water Storage Reconstruction Since 1941 Using Spatiotemporal‐Aware Deep Learning Model

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Terrestrial water storage (TWS) plays an important role in describing the Earth system, as water availability is decisive for ecosystems and human development. Since 2002, the Gravity Recovery and Climate Experiment (GRACE) and its Follow‐On (GRACE‐FO) mission have measured TWS anomalies with unprecedented accuracy, enabling a leap in ...

Disentangling the oceanic drivers behind the post-2000 retreat of Sermeq Kujalleq, Greenland (Jakobshavn Isbræ) [PDF]

The Cryosphere
Ocean temperatures have warmed in the fjords surrounding the Greenland Ice Sheet, causing increased melt along their ice fronts and rapid glacier retreat and contributing to rising global sea levels.

Quantifying flow and stress in ice mélange, the world’s largest granular material. [PDF]

, 2018
Tidewater glacier fjords are often filled with a collection of calved icebergs, brash ice, and sea ice. For glaciers with high calving rates, this “m ́elange” of ice can be jam-packed, so that the flow of ice fragments is mostly determined by ...

Icebergs, sea ice, blue carbon and Antarctic climate feedbacks [PDF]

, 2018
Sea ice, including icebergs, has a complex relationship with the carbon held within animals (blue carbon) in the polar regions. Sea-ice losses around West Antarctica's continental shelf generate longer phytoplankton blooms but also make it a hotspot for ...

Forest harvest and natural stressors compound to reduce juvenile ungulate survival

Journal of Applied Ecology, Volume 63, Issue 2, February 2026.
Anthropogenic disturbances, such as forest harvest, create risky landscapes for juveniles by increasing their vulnerability to predation and hunting, and when combined with natural stressors like parasitism, likely drive population declines. Managing landscapes with a species‐centric approach that addresses the cumulative effects of human and natural ...

Monte Carlo ice flow modeling projects a new stable configuration for Columbia Glacier, Alaska, c. 2020 [PDF]

The Cryosphere, 2012
Due to the abundance of observational datasets collected since the onset of its retreat (c. 1983), Columbia Glacier, Alaska, provides an exciting modeling target.

Safety and efficacy of a feed additive consisting of zinc‐lysinate sulfate for all animal species (Phytobiotics Futterzusatzstoffe GmbH)

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of Zinc‐lysinate sulfate (Plexomin® L‐Zn) as a nutritional feed additive for all animal species and categories. The applicant has provided evidence that, in essence, the additives under assessment comply with the proposed
