Stratified suppression of turbulence in an ice shelf basal melt parameterisation Open
Ocean-driven basal melting of Antarctic ice shelves is an important process that affects the Antarctic Ice Sheet, global climate and sea level. Basal melting is controlled by small-scale processes; therefore ice shelf–ocean models rely on …

Wind‐Driven Variability of Modified Circumpolar Deep Water Intrusions Into Vincennes Bay, East Antarctica Open
Warm water intrusions onto Antarctica's continental shelves have the potential to rapidly melt ice shelves and destabilize glaciers. However, uncertainties remain about the mechanisms driving these intrusions and their variability, in part…

Seasonal variability of ocean heat transport and ice-shelf basal melt around Antarctica Open
The delivery of ocean heat to Antarctic ice shelves is due to intrusions of waters warmer than the local freezing point temperature. Changes in the supply of ocean heat will determine how rapidly ice shelves melt at their base, which affec…

Quantification of Antarctic Bottom Water Pathways in the Australian‐Antarctic Basin Open
Antarctic Bottom Water (AABW) formation drives the lower limb of the meridional overturning circulation, influencing the Earth's climate, carbon cycle, and marine biological productivity. Recent findings suggest that AABW across the Southe…

Sensitivity of Antarctic Bottom Water Formation and Export to Horizontal Model Resolution Open
The formation of Antarctic Bottom Water (AABW) is a key process in the global ocean circulation, but modeling the formation and downslope flow of AABW represents an ongoing challenge for ocean and climate models due to the high horizontal …

Antarctic Dense Water Formation Sensitivity to Ocean Surface Cell Thickness Open
Dense water formation on the Antarctic continental shelf is the main process by which Antarctic Bottom Waters form and is fundamental to the abyssal overturning circulation. However, most ocean models fail to simulate Antarctic dense water…

Results of the second Ice Shelf – Ocean Model Intercomparison Project (ISOMIP+) Open
Ocean-driven basal melting of Antarctic ice shelves plays an important role in the mass loss of the Antarctic Ice Sheet. Ice shelf cavity-resolving ocean models are a valuable tool for understanding ice shelf-ocean interactions and for sim…

The variability of Antarctic dense water overflows can be observed from space Open
Around the margins of Antarctica, dense waters formed on the continental shelf are exported to oceanic depths. This overflow of dense waters to the abyss ventilates the ocean, and is vital to the global overturning circulation. Accurately …

Sensitivity of Antarctic dense water formation to surface vertical resolution Open
Dense water formation on the Antarctic continental shelf drives the abyssal overturning circulation, being the main process by which Antarctic Bottom Waters form. Despite its importance, most ocean models cannot simulate dense water format…

Stratified suppression of turbulence in an ice shelf basal melt parameterisation Open
Ocean-driven basal melting of Antarctic ice shelves is an important process that affects the Antarctic Ice Sheet, global climate and sea level. Basal melting occurs within ice shelf cavities, which are not represented in most global ocean …

Floating debris and organisms can raft to Antarctic coasts from all major Southern Hemisphere landmasses Open
Antarctica's unique marine ecosystems are threatened by the arrival of non‐native marine species on rafting ocean objects. The harsh environmental conditions in Antarctica prevent the establishment of many such species, but warming around …

Closing the Loops on Southern Ocean Dynamics: From the Circumpolar Current to Ice Shelves and From Bottom Mixing to Surface Waves Open
A holistic review is given of the Southern Ocean dynamic system, in the context of the crucial role it plays in the global climate and the profound changes it is experiencing. The review focuses on connections between different components …

GRACE satellite observations of Antarctic Bottom Water transport variability Open
Antarctic Bottom Water (AABW) formation and transport constitute a key component of the global ocean circulation. Direct observations suggest that AABW volumes and transport rates may be decreasing, but these observations are too temporall…

The Southern Ocean Hub for Nutrients, Micronutrients, and Their Isotopes in the Global Ocean Open
The sustenance of marine primary productivity depends on the supply of macro- and micronutrients to photosynthesizers in the ocean’s sunlit surface. Without supply from the deep, sinking particles would deplete the upper ocean of these vit…

Observing Antarctic Bottom Water in the Southern Ocean Open
Dense, cold waters formed on Antarctic continental shelves descend along the Antarctic continental margin, where they mix with other Southern Ocean waters to form Antarctic Bottom Water (AABW). AABW then spreads into the deepest parts of a…

Decoupling of the Surface and Bottom‐Intensified Antarctic Slope Current in Regions of Dense Shelf Water Export Open
The Antarctic Slope Current is guided by the topographic gradient of the Antarctic continental slope and creates a dynamical barrier between the continental shelf and the open ocean. The current's vertical structure varies around the conti…
