Flow‐pattern evolution of the Scandinavian Ice Sheet indicated by the subglacial lineation record over Norway, Sweden and Finland

Boreas, EarlyView.
We present a 25‐stage reconstruction of the ice‐flow pattern evolution of the Scandinavian Ice Sheet based on mapping and analysis of ~240 000 subglacial lineations and lineation fields across Norway, Sweden, Finland, and parts of NW Russia. Our reconstruction uses a glacial geomorphological inversion approach, in which we generated 611 individual ...

Modelling ice dynamic contributions to sea level rise from the Antarctic Peninsula [PDF]

, 2015
The future ice dynamical contribution to sea-level rise (SLR) from 210 ice shelf nourishing drainage basins of the Antarctic Peninsula Ice Sheet (APIS) is simulated, using the British Antarctic Survey Antarctic Peninsula Ice Sheet Model.

Thorncliffe Formation: A proglacial to subglacial lacustrine basin sequence, Greater Toronto Region, Canada

Boreas, EarlyView.
Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Short-term Antarctic ice-sheet dynamics during the late Oligocene

Communications Earth & Environment
Palaeoceanographic records spanning the Oligocene provide insights into Antarctic ice-sheet dynamics in a world warmer-than-today, allowing us to improve future climate projections linked to global warming.

Outbursts from an ice-marginal lake in Antarctica in 1969–1971 and 2017, revealed by aerial photographs and satellite data

Scientific Reports, 2023
The liquid water around the Antarctic Ice Sheet plays a key role in modulating both the vulnerability of ice shelves to hydrofracturing and ice discharge from outlet glaciers.

GRANTSISM: An Excel™ ice sheet model for use in introductory Earth science courses [PDF]

, 2018
GRANTISM (GReenland and ANTarctic Ice Sheet Model) is an educational Excel™ model introduced by Pattyn (2006). Here, GRANTISM is amended to simulate the Svalbard-Barents-Sea Ice Sheet during the Last Glacial Maximum, an analogue for the contemporary West

Characterisation of a cold‐adapted, thermostable glucokinase from psychrophilic Pseudoalteromonas sp. AS‐131 reveals how the enzyme achieves high thermal stability without loss of cold adaptation

The FEBS Journal, EarlyView.
We investigated glucokinase from the psychrophilic Pseudoalteromonas sp. AS‐131 (PsGK), which was isolated from the Antarctic Ocean. Biochemical studies revealed that PsGK is a cold‐adapted enzyme with high thermal stability, in contrast to general cold‐adapted enzymes, which have low thermal stability.

Impacts of marine instability across the East Antarctic Ice Sheet on Southern Ocean dynamics [PDF]

, 2016
Recent observations and modelling studies have demonstrated the potential for rapid and substantial retreat of large sectors of the East Antarctic Ice Sheet (EAIS). This has major implications for ocean circulation and global sea level.

Unilateral Action on Climate Change and the Moral Obligation to Take Leadership

Journal of Social Philosophy, EarlyView.
ABSTRACT We claim that a moral obligation to take climate leadership by means of unilateral mitigation depends on the existence of a plausible follow‐the‐leader mechanism whereby unilateral mitigation by some increases the probability of sufficient mitigation by others to avert catastrophic climate impacts.
