Exploring the submarine geomorphology of Te Rua-o-te-Moko Fiordland, Aotearoa New Zealand

Frontiers in Earth Science
Temperate fjords serve as key environments for understanding glacial landscape evolution, sedimentary processes, and dynamics. These overdeepened, glacially carved inlets serve as high-resolution repositories of past climate and ice behaviour.

A note on hysteresis in glaciology

Applied Mathematics Letters, 2000
Recent studies on the mechanism governing the Laurentide ice sheet oscillations of the Last Ice Age focus on the most critical effect of the basal hydraulic processes enhanced when the ice is sliding along soft deformable beds. To understand the import of this, we consider {A. C. Fowler} and \textit{C. Johnson}'s 0-D hydrological flow model [J. Glaciol.

Insights into Red Deer Ecology during the Late Epigravettian: New isotopic evidence from Riparo Tagliente (Italian Prealps)

Journal of Quaternary Science, EarlyView.
Abstract The transition from the Last Glacial Maximum to the Late Glacial marked a shift from the cold conditions of Greenland Stadial‐2 (GS‐2) to the warmer phases of Greenland Interstadial‐1 (GI‐1), enabling the reoccupation of Alpine regions by Late Palaeolithic hunter‐gatherers.

Bridging worlds

Mètode Science Studies Journal: Annual Review
In high-mountain regions, climate change adaptation represents a major challenge, both now and in the future, particularly in issues related to water management and the continued degradation and loss of glaciers. While scientific knowledge on the subject

Late Quaternary climatic variability in the Eastern Mediterranean recorded in Hermes Cave, Corinth Rift, Greece

Journal of Quaternary Science, EarlyView.
ABSTRACT The Greek peninsula lies at the intersection of major atmospheric circulation systems, making it a key location for reconstructing past climate variability in the Eastern Mediterranean. In this study, we present a new high‐resolution multi‐proxy speleothem record from Hermes Cave, located on the shoulder of the Corinth Rift in southern Greece.

Evolving ice fraction in the shallow firn layer of Devon Ice Cap, Canada, between 2012 and 2022

Journal of Glaciology
Firn can store glacial meltwater and delay contribution to sea level rise, but ice layers and ice slabs within the shallow firn layer can impede the downward percolation of melt. Here we report firn conditions along a transect on southwest Devon Ice Cap (

Stable water isotopes and the physical environment

Belgeo, 2002
This paper presents the characteristics of the fractionation of water isotopes which occurs during evaporation and freezing of water. It shows how these characteristics can be used for studying some aspects of the physical environment, namely ...

Astragalus ecomorphology in Quaternary elephantids

Journal of Quaternary Science, EarlyView.
ABSTRACT The astragalus plays a fundamental role in the graviportal locomotion of proboscideans, reflecting the biomechanical constraints imposed by large body masses. This study analyses the morphological variability of the astragalus in Quaternary elephantids using linear biometry and 3D geometric morphometrics, incorporating an unpublished ...

Ice thickness of the northern half of the Patagonia Icefields of South America from high‐resolution airborne gravity surveys

Geophysical Research Letters, 2016
We employ high‐resolution, high‐precision, helicopter‐borne gravity observations of the Northern (NPI) and Southern Patagonia Icefields (SPI), South America, to infer ice thickness and bed topography using a three‐dimensional model constrained by Fjord ...

Proglacial lake records of Holocene glacier behaviour and catchment processes in Slettedalen, Northeast Greenland

Journal of Quaternary Science, EarlyView.
ABSTRACT Constraining Arctic catchment response to Holocene climate change is vital for understanding future environments. We present detailed sedimentological, geochemical and grain size end‐member analysis of two Holocene (~7.0 ka to present) lake sequences, S1 and S2, close to Zackenberg, Northeast Greenland.
