Blue-ice moraines formation in the Heritage Range, West Antarctica: Implications for ice sheet history and climate reconstruction

Quaternary Science Advances, 2022
Blue ice is found in areas of Antarctica where katabatic winds, focussed by steep surface slopes or by topography around nunataks, cause enhanced surface ablation.

Glacial and Subglacial Topography of West Antarctica [PDF]

Journal of Glaciology, 1961
AbstractA summary of the techniques used and results obtained from three oversnow traverses in Marie Byrd Land and the Ellsworth Highland between January 1957 and January 1959 is presented. Seismic reflection shooting at 30 nautical mile (55.5 km.) intervals was combined with gravity, magnetic and altimetric measurements to determine the glacial and ...

Critical constraints to ecological buffering in a rapidly changing Arctic: A long‐term seabird study

Journal of Animal Ecology, EarlyView.
Drawing on two decades of research in East Greenland, this study shows that little auks, key seabird indicators of Arctic ecosystem health, can adapt to rapid environmental change through behavioural flexibility. However, increasing storms and mercury pollution are pushing resilience to its limits, providing an early warning of broader Arctic ...

Archiving the History of Environmentalism: Insights from Academia and Practice

History, EarlyView.
Abstract This Forum considers the current state of archiving for the environmental movement at local, national and international levels. It responds to a gap that researchers of environmentalism have long been aware of, but one that is poorly understood from the perspective of records management and collections development practice.

Indian summer monsoon rainfall drives Antarctic climate and sea ice variability through atmospheric teleconnections

npj Climate and Atmospheric Science
In recent decades, Antarctica has undergone significant climate change, with most studies focusing on the impact of oceanic multiscale variability on Antarctica, especially on West Antarctica. However, our research reveals that Indian summer monsoon (ISM)

The Momentum of ‘Developed’: Bodies of Water, Aging Bodies and Malta's Interventions at the UN

History, EarlyView.
Abstract Histories of major powers continue to shape how many scholars conceptualize internationalism. By focusing on Malta's interventions at the UN challenges, this article challenges such narrative. In particular, it examines Arvid Pardo's 1967 petition that the seabed be reconceived and protected as the ‘common heritage of mankind’ and Vincent ...

Interior Antarctica is undergoing marked climate change

Communications Earth & Environment
2024 is the warmest year in NASA’s 145-year climate record. Unlike the Arctic, which has experienced significantly faster warming than the global average, Antarctic temperature change is variable.

The experiment of integrated mobile technologies used for deep hydrocarbon accumulation prospecting and geophysical mapping at the West Antarctic bottom structures

Геофизический журнал, 2017
The data obtained confirm earlier assumption about possible existence of large accumulations of oil and gas hydrates in this part of the West Antarctica. Their formation in the structures of passive continental margin of the Antarctic Peninsula occurred

Holocene Deglaciation of Marie Byrd Land, West Antarctica [PDF]

Science, 2003
Surface exposure ages of glacial deposits in the Ford Ranges of western Marie Byrd Land indicate continuous thinning of the West Antarctic Ice Sheet by more than 700 meters near the coast throughout the past 10,000 years. Deglaciation lagged the disappearance of ice sheets in the Northern Hemisphere by thousands of years and may still be under way ...

Significant Far‐Right Challenges to Australian Society? The XYZ and AustraliaOne

Australian Journal of Politics &History, EarlyView.
ABSTRACT Scholars who analyse the Australian far‐right from a criminological or security studies perspective propose that activists and groups pose ‘political’ challenges to Australian society. This paper examines the far‐right news website The XYZ and the AustraliaOne political party, and argues that claims that the far‐right may normalise ...
