Ice Sheets Without Dynamic Topography

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Dynamic topography results in uplift and subsidence events on Earth's surface with amplitudes on the order of a kilometer. These vertical motions are known to have influenced ice sheet evolution, but how dynamic topography has controlled the current state of present ice sheets is unknown.

Trace Metal Contamination and Health Risk Assessment in Traditional Egyptian Soft Cheeses: A Food Safety Perspective

open access: yesFood Safety and Health, Volume 3, Issue 4, Page 693-712, October 2025.
This study evaluates trace metal concentrations in traditional Egyptian soft cheeses and assesses associated health risks using chemometric and toxicological approaches. Findings confirm the safety of these cheeses, with all risk indices within acceptable limits, supporting the need for continued monitoring to ensure food quality and consumer ...

An extension of Satoh's algorithm and its implementation [PDF]

open access: yes, 2000
International audienceWe describe a fast algorithm for counting points on elliptic curves defined over finite fields of small characteristic, following Satoh. Our main contribution is an extension to characteristics two and three.

Rift‐Related Sedimentary Basin and Deeper‐Seated Mafic Intrusions Modeled Beneath Thwaites Glacier, West Antarctica: Influence on Glacier Dynamics

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Thwaites Glacier in West Antarctica has been identified as a route to destabilization of the whole West Antarctic Ice Sheet, potentially leading to several meters of sea‐level rise. However, future evolution of Thwaites Glacier remains uncertain due to a lack of detailed knowledge about its basal boundary that will affect how its retreat ...

Subglacial landscape formation and sediment discharge: relating basal conditions to bedform dimensions and properties at Rutford Ice Stream, West Antarctica

open access: yesBoreas, Volume 54, Issue 4, Page 672-686, October 2025.
Basal conditions that facilitate fast ice flow are still poorly understood and their parameterization in ice‐flow models results in high uncertainties in ice‐flow and consequent sea‐level rise projections. Direct observations of basal conditions beneath modern ice streams are limited due to the inaccessibility of the bed.

Mapping Ice Stream Sensitivity in the Amundsen Sector to Uncertainty in Ice Velocity Observations

open access: yesGeophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Satellite‐derived ice‐velocity products are essential for initializing ice‐sheet models and forecasting ice evolution in a warming climate. Understanding where sea‐level rise (SLR) projections are sensitive to observational errors is key to improve model accuracy and reduce uncertainty.

Fast Algorithms for Finding the Characteristic Polynomial of a Rank-2 Drinfeld Module [PDF]

open access: yes, 2018
This thesis introduces a new Monte Carlo randomized algorithm for computing the characteristic polynomial of a rank-2 Drinfeld module. We also introduce a deterministic algorithm that uses some ideas seen in Schoof's algorithm for counting points on ...

Evolution of Shear‐Zone Fractures Presages the Disintegration of Thwaites Eastern Ice Shelf

open access: yesJournal of Geophysical Research: Earth Surface, Volume 130, Issue 9, September 2025.
Abstract Thwaites Eastern Ice Shelf (TEIS) is a partially confined floating extension of Thwaites Glacier, anchored by an offshore pinning point at its northern terminus. Over the past two decades, the shelf has experienced progressive fracturing around a prominent shear zone upstream of its pinning point, gradually compromising its structural ...
