Mind &Language, EarlyView.Attentional guidance plays two crucial roles in temporally extended agency. First, guidance stabilizes attention onto our tasks—and tunes out distractions—for extended periods of time. Second, guidance makes attention telic/atelic. Guidance imposes completion conditions on telic attention (e.g., searching for your keys) but not atelic attention (e.g ...

Frontiers in Earth Science, 2020 Projections of future ice sheet mass loss and thus sea level rise rely on the parametrization of iceberg calving in ice sheet models. The interconnection between submarine melt-induced undercutting and calving is still poorly understood, which makes ...

Sedimentology, EarlyView.ABSTRACT The standard subdivision of a distributive fluvial system (DFS) into proximal, medial and distal zones is typically based on the proportion of channel bodies and/or the degree of channel amalgamation, reflecting a downstream fining trend towards a mud‐prone terminal pinch‐out.

Crevasse advection increases glacier calving
Journal of Glaciology, 2022 Iceberg calving, the process where icebergs detach from glaciers, remains poorly understood. Moreover, few parameterizations of the calving process can easily be integrated into numerical models to accurately capture observations, resulting in large ...

Three-dimensional modelling of calving processes on Johnsons Glacier, Livingston Island, Antarctica. [PDF]
, 2010 Iceberg calving is an important mass loss mechanism from ice shelves and tidewater glaciers for many mid and high-latitude glaciers and ice caps, yet the process is not well represented in prognostic models of ice dynamics.

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT Ice shelves are floating seaward extensions of glaciers that form where land‐based ice flows into the ocean. Recent observations suggest that their mechanical behavior is suitably described by a viscoelastic Maxwell model, as this framework captures both the instantaneous elastic response and the time‐dependent viscous flow of ice.

Blocking a wave: frequency band gaps in ice shelves with periodic crevasses [PDF]
, 2012 We assess how the propagation of high-frequency elastic-flexural waves through an ice shelf is modified by the presence of spatially periodic crevasses.

Crevasse-induced Rayleigh-wave azimuthal anisotropy on Glacier de la Plaine Morte, Switzerland
Annals of Glaciology, 2019 Crevasses and englacial fracture networks route meltwater from a glacier's surface to the subglacial drainage system and thus influence glacial hydraulics.

Fracture and Calving Front Evolution: A Case Study of Fimbul Ice Shelf, Antarctica
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT This study combines historical records, satellite remote sensing data, and inverse modelling to investigate crack formation and calving front evolution of the Fimbul Ice Shelf, Antarctica. Historical maps from the 1950s, together with satellite imagery from 1970s–2026, are used to reconstruct calving‐front positions and track the evolution of ...
