The deep glacial trough and hinterland of the Denman Glacier (East Antarctica) makes the area around the Shackleton ice shelf sensitive to ice loss due to warmer deep water intruding onto the continental shelf in the near future. In addition…
The marine-based West Antarctic Ice Sheet (WAIS) is considered vulnerable to irreversible collapse under future climate trajectories, and its tipping point may lie within the mitigated warming scenarios of 1.5° to 2°C of the United Nations Paris Agreement.
The papers in this volume were, with a few exceptions, presented at the third Island Invasives conference, held in Dundee, Scotland in July 2017. The papers demonstrate up-scaling in several aspects of eradication operations – not least in ambition, land area, operational size…
Carbon monoxide (CO) is a naturally occurring atmospheric trace gas, a regulated pollutant, and one of the main components determining the oxidative capacity of the atmosphere. Evaluating climate…
Sewage discharge into near-shore marine ecosystems is one of the most common forms of contamination that occurs in Antarctica today, and is likely to impact on the biota living in these habitats. In this study the morphological responses of four species of Abatus heart urchins (A. philippii, A.
The Southern Ocean islands are some of the most isolated landmasses in the world. Few of the islands support permanent human settlements or land based industries and as such they remain as some of the most uninvaded landscapes globally.
This article summarises the history of the discovery of emperor penguin Aptenodytes forsteri colonies. Emperor penguins were probably first seen on James Cook’s second voyage (1773–1775) but were not recorded as a … separate species until 1844.
Reconstructing and modeling extent and dynamics of ice sheets is crucial in … understanding and predicting the evolution of ice sheets. Key to ice sheet dynamics are ice … streams, which drain most of the ice from the ice sheet interior to the ice shelves, where most of … the ice is lost.

Anthropogenic carbon dioxide has been accumulating in the … oceans, lowering both the concentration of carbonate ions … and the pH (ref. 1), resulting in the acidification of sea … water.
Past changes in East Antarctic Ice Sheet (EAIS) volume are poorly known and diffi cult to … measure, yet are critical for predicting the response of the ice sheet to modern climate change. In particular, it is important to identify the sources of sea-level rise since the Last Glacial … Maximum (LGM)…
