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 […]
Mesopelagic fishes transport a vast biomass of organic material between surface and deep waters through diel vertical migration (DVM), which plays a crucial role in both food web functioning and […]
The Antarctic and the surrounding ocean are a vast icescape elusive to mankind at large, albeit critical to the region and to the global climate and ecosystems. Our project combines […]
Wildfires in the Arctic-boreal zone have increased in frequency over recent decades, carrying substantial ecological, social, and economic consequences. Remote sensing is crucial for mapping burned areas, monitoring wildfire dynamics, […]
Hiss waves frequently occur in the plasmasphere or plumes, playing a key role in energetic electron loss in the Earth’s inner magnetosphere. While previous studies have linked hiss wave enhancements […]
Question: The stress gradient hypothesis predicts that extreme environments favour positive over negative species interac-tions, that is, facilitation over competition. However, along the Antarctic Peninsula (maritime Antarctic), we observed indirectevidence […]
Paleoceanographic evidence detailing the evolution of ocean carbon sequestration at high resolution across the Mid-Pleistocene Transition (MPT; 1.2–0.7 Ma, million years ago) remains scarce. Here, we present a continuous record […]
