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 […]
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 […]
As the Earth warms, the Arctic Ocean is expected to be dominated by thin ice that forms and melts each year, with little thick multiyear ice. To understand the Arctic […]
Antarctic fur seals are an important predator in the Southern Ocean, with > 95% of the population breeding at South Georgia. Female seals generally pup on open beaches, but many […]
Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice-covered regions, these areas […]
