Interleaving layers are commonly observed in the subsurface ocean near thermohaline fronts. They imply a lateral exchange of water mass properties and have been shown to influence both lateral and vertical mixing rates. We examine a set of in situ observations…
Basal sliding in Antarctic glaciers is often modeled using a friction law that relates basal shear stresses to the effective pressure. As few ice sheet models are dynamically coupled to subglacial hydrology models…
The Mount Brown South (MBS) ice core in East Antarctica (69° S, 86° E) has produced records of sea salt concentration and snow accumulation for examining past climate. In a previous study, the sea salt concentration, but not snow accumulation, showed a significant…
This paper presents the global analysis of two extended decreases in the galactic cosmic-ray intensity observed by worldwide networks of ground-based detectors in 2012. This analysis is capable of separately deriving the cosmic-ray density (or omnidirectional intensity) and anisotropy…
Continent-continent collisions develop mature orogenic systems over tens of millions of years, creating a thermally weakened mid-crustal infrastructure layer (15–50 km deep) that flows laterally from the thickened mountain ranges or plateaus.
Interleaving layers are commonly observed in the subsurface ocean near thermohaline fronts. They imply a lateral exchange of water mass properties and have been shown to influence both lateral and vertical mixing rates. We examine a set of in situ observations…
The vertically integrated zonal momentum balance of the Antarctic Circumpolar Current (ACC) is dominated by wind stress at the surface and topographic form stress (TFS) at the bottom. It has been argued that wind stress is transferred from the surface to the bottom by transient baroclinic eddies…
The present-day state and future of the Antarctic Ice Sheet depend on the rate at which the ocean melts its fringing ice shelves. Ocean heat must cross many physical and dynamical barriers to melt ice shelves, with the last of these being the ice-ocean boundary layer.
Under the recently adopted Kunming-Montreal Global Biodiversity Framework, 196 Parties committed to reporting the status of genetic diversity for all species. To facilitate reporting, three genetic diversity indicators were developed…
Sea ice kinematics impacts the global ocean–atmosphere system in numerous ways: modification of albedo, ice cover, and ice mass; heat transmission between atmosphere and ocean; and ice thickness distribution.
Near-synchronized in situ, space-borne (A-Train) and ground-based … lidar observations are employed to evaluate the boundary-layer clouds (BLCs) over Tasmania and the adjacent Southern Ocean (SO) simulated by the … limited-area version of Australian Community Climate and Earth System … Simulator…
For many species trophic interactions are difficult to study because of their cryptic habits and/or the unfavourable characteristics of samples for traditional diet techniques. DNA-based diet techniques are sensitive…
