1. Wing shape changes as a proxy for invasion success in Antarctica: case study of Psychoda albipennis (Psychodidae) using geometric morphometrics

   Invasions of exotic species in fragile and pristine ecosystems, such as those of Antarctica, is a growing ecological concern. Psychoda albipennis, a cosmopolitan saprophagous fly, has recently become established in […]

2. Theme 5: Anthropogenic signatures in Antarctica: the race against pollution and other pressures [White paper]

   Theme 5 examines the impacts of human activities on Antarctica, including scientific operations, tourism, fisheries, and shipping, and their interactions with climate change, with the aim of informing environmental policy […]

3. Overlap of nonbreeding wandering albatrosses with fisheries and implications for colony‐specific population trajectories at South Georgia

   Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best […]

4. A 26-Year Record of Seasonality and Interannual Variability in Marine Mammal Sightings From Northern Marguerite Bay, Antarctica

   Whales and seals are an important and often conspicuous component of the Southern Ocean pelagic fauna. Some species have been studied extensively, but almost exclusively in the austral summer, and […]

5. The Microbiome of an Invasive Antarctic insect, Eretmoptera Murphyi (Diptera: Chironomidae), and its Potential Role in Nutrient Cycling

   Eretmoptera murphyi Schaeffer 1914 is a flightless chironomid midge endemic to South Georgia in the sub-Antarctic. In the 1960s it was accidentally introduced to Signy Island (in the more extreme […]

6. Anthropogenic aerosols can shape the winter mid-latitude cyclone tracks

   Mid-latitude cyclones are “parent storms” of various weather hazards and contribute significantly to the moisture and heat intrusion into the Arctic. Anthropogenic aerosols are known to affect cyclone intensities and […]

7. Assessment of land‐based threats to Atlantic pelagic seabirds

   Seabirds are exposed to numerous threats throughout their life‐cycles, including land‐based threats during their breeding season such as invasive species, diseases, or light pollution. Here we assess the timing, scope, […]

8. High Voltage DC Active Current Injection to Simulate Geomagnetically Induced Currents in New Zealand

   This study investigates the effects of geomagnetically induced currents (GIC) on New Zealand’s electrical infrastructure via an intentional ground injection of direct current (DC) from a high voltage DC converter […]

9. Fanning the flames: Past and future links between climate change and fire activity across boreal forests

   Boreal forests are experiencing unprecedented environmental change, with increasing fire activity posing significant ecological and climatic challenges. This thesis investigates past, present and future interactions between climate and fire across […]

10. West Antarctic ice-rafted debris: sources, signatures, and signals of past ice-sheet dynamics

    The West Antarctic Ice Sheet (WAIS) is a critical component of the Earth’s climate system, and its stability (or instability) is a major source of uncertainty in projections of global […]

11. The mysteries of reactive nitrogen species above polar snow

    Emission of NOx and HONO from the snowpack can have a significant impact on the oxidising capacity of the boundary layer in the polar regions. This thesis presents work that […]

12. Semi‐automated seal detection on the Western Antarctic Peninsula: an unsupervised machine learning approach for detecting ice seals in aerial survey data

    Over the past 25 years, the Western Antarctic Peninsula (WAP) has experienced dramatic shifts in sea ice extent. This change has coincided with rapid alterations in ice‐dependent ecosystems, including those […]
