Ice cores provide an un-matched high-resolution archive into paleoclimate reconstruction that other environmental archives (e.g. coral, sediment cores, and tree rings) do not. Limited research has focussed on terrestrial organic […]
Cephalopods are crucial to the Southern Ocean ecosystem, connecting top predators with mid-trophic organisms, yet their ecology in the Pacific sector is not well understood. This research used stable isotope […]
Antarctica harbors many distinctive features of life, yet much about the diversity and functioning of Antarctica’s life remains unknown. Evolutionary histories and functional ecology are well understood only for vertebrates, […]
Mechanisms regulating material transfer from subducted slabs to arc magmas remain debated, centered on metasomatized mantle wedge interactions versus mélange mobilization at the slab-mantle interface. The South Sandiwch Islands arc […]
Many studies have reported the paradoxical observation of high concentrations of low‐density microplastics (plastic particles < 5 mm) in deep‐sea sediments despite their buoyancy. The incorporation of buoyant microplastics into […]
In this study, we evaluated the pathogenic potential of the fungi Aspergillus thermomutatus and Rhodotorula mucilaginosa obtained from maritime Antarctic permafrost using in vivo experiments on immunocompromised BALB/c mice. Despite […]
The Southern Ocean is experiencing major environmental and ecological changes which could drastically alter communities and impact ecosystem functioning. We still have a poor understanding of the structure of Southern […]
Microplastic pollution in remote inland Antarctica is largely unknown. This study explored the plastic footprint of snow from remote Antarctic camps: Union Glacier, Schanz Glacier and the South Pole. Refined […]
Hydrocarbon spillage has long been a concern in Antarctica as it can result in detrimental effects on Antarctic biota and ecosystems. Bioremediation, using microorganisms such as microalgae, represents one of […]
In the polar regions, there is significant model bias in the number concentrations and seasonality of sea salt aerosol (SSA) due to the lack of understanding of aerosol sources associated […]
This thesis details the development and application of a pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) method for the quantification of microplastic pollution in terrestrial samples. Initial analysis of plastic standards using Py-GC/MS […]
