The use of Remotely Piloted Aerial Systems (RPAS), also referenced as Uncrewed Aerial Vehicles (UAVs) and more generally as drones, is increasingly prevalent across various scientific disciplines, enabling the collection […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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, […]
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 […]
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 […]
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 […]
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 […]
