Upper-Ocean Processes and Sea Ice Production in the Southeastern Amundsen Sea Polynya in Austral Autumn Open
The mixed layer of polynyas is vital for local climate as it determines the exchange of properties and energy between ocean, sea ice, and atmosphere. However, its evolution is poorly understood, as it is controlled by complex interactions …

Swirls and scoops: Ice base melt revealed by multibeam imagery of an Antarctic ice shelf Open
Knowledge gaps about how the ocean melts Antarctica’s ice shelves, borne from a lack of observations, lead to large uncertainties in sea level predictions. Using high-resolution maps of the underside of Dotson Ice Shelf, West Antarctica, w…

Interactions between internal tides and turbidity currents: an under-recognized process in deep-marine stratigraphy? Open
Deep-sea currents transfer sediment, nutrients, and pollutants, which drive climatic, ecological and geomorphological variation in the global ocean. The complex interaction of downslope currents and internal tides in submarine canyons has …

Assessing the Structural Stability of Thwaites Eastern Ice Shelf and Its Influence on the Future Evolution of Thwaites Glacier Open
The Thwaites Eastern Ice Shelf stands as the last remaining floating extent of the consequential Thwaites Glacier in West Antarctica. In the past, it has provided buttressing of the grounded glacier ice, but in the last decade the ice shel…

Effect of ocean tidal mixing on exoplanet climates and habitability Open
Due to their abundance and their observational advantages, M dwarfs offer the best chance of finding habitable planets through sheer numbers. Therefore, in the race to detect signs of life beyond the Solar System, rocky M-dwarf planets off…

Heat and meltwater fluxes across the front of Dotson ice shelf cavity, Amundsen Sea Open
Ice shelves terminating in the Amundsen Sea are losing mass rapidly, exporting an increasing amount of meltwater into the ocean. Investigation into the melt rates of ice shelves near in the Amundsen Sea is therefore crucial for predicting …

High resolution pH measurements at the edge of the Dotson Ice shelf using state-of-the-art autonomous technologies. Open
The global ocean takes up about a quarter of anthropogenic carbon dioxide emissions, with the Southern Ocean playing a disproportionately large role. This uptake has led to changes in the Southern Ocean's carbonate chemistry, reducing pH t…

The modelled climatic response to the 18.6-year lunar nodal cycle and its role in decadal temperature trends Open
The 18.6-year lunar nodal cycle arises from variations in the angle of the Moon's orbital plane. Previous work has linked the nodal cycle to climate but has been limited by either the length of observations analysed or geographical regions…
