1. 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 […]

2. 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 […]

3. An Arctic Sea Ice Energy Budget for the Last Interglacial

   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 […]

4. Uncovering Hidden Predators: Thermal Drone Detection of Antarctic Fur Seals in Tussac Grass at South Georgia

   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 […]

5. Enabling Under Ice Glider Operations: A Backseat Driver Approach

   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 […]

6. Dynamics of daily vertical migration in mesopelagic fish communities across the Southern Ocean

   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 […]

7. Sounding Antarctica: The Sea-Ice Record

   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 […]

8. Burned area mapping across the Arctic-boreal zone with Landsat and Sentinel-2 imagery

   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, […]

9. Hiss Wave Evolution During Substorms Based on Van Allen Probes Observations

   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 […]

10. Neighbourly Dispute at the Edge of Life: Species Interactions Among Antarctic Mosses

    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 […]

11. Southern Ocean Vertical Carbon Stratification Across the Mid‐Pleistocene Transition

    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 […]

12. Topographic effects of Svalbard on warm and moist air intrusions into the Central Arctic

    Warm air intrusions (WAIs) along the North Atlantic pathway are key drivers of warm extremes in the central Arctic. The Svalbard archipelago acts as a major topographic barrier in the […]
