Recent results from the ARIANNA neutrino experiment [PDF]

, 2016
The ARIANNA experiment is currently taking data in its pilot-phase on the Ross ice-shelf. Fully autonomous stations measure radio signals in the frequency range from 100 MHz to 1 GHz. The seven station HRA was completed in December 2014, and augmented by

Investigation of land ice-ocean interaction with a fully coupled ice-ocean model, Part 1: Model description and behavior [PDF]

, 2012
Antarctic ice shelves interact closely with the ocean cavities beneath them, with ice shelf geometry influencing ocean cavity circulation, and heat from the ocean driving changes in the ice shelves, as well as the grounded ice streams that feed them.

Influence of basal melting on ice surface fracture and glacier retreat: A case study at Pine Island Glacier [PDF]

Polish Polar Research
Pine Island Glacier (PIG) is one of the most dynamic ice streams in West Antarctica, with significant basal melting and ice shelf retreat profoundly influencing its behavior.

Frazil ice formation in an ice shelf water plume [PDF]

Journal of Geophysical Research: Oceans, 2004
We present a model for the growth of frazil ice crystals and their accumulation as marine ice at the base of Antarctic ice shelves. The model describes the flow of buoyant water upward along the ice shelf base and includes the differential growth of a range of crystal sizes.

Decadal Variability of Ice‐Shelf Melting in the Amundsen Sea Driven by Sea‐Ice Freshwater Fluxes

Geophysical Research Letters
The ice streams flowing into the Amundsen Sea, West Antarctica, are losing mass due to changes in oceanic basal melting of their floating ice shelves. Rapid ice‐shelf melting is sustained by the delivery of warm Circumpolar Deep Water to the ice‐shelf ...

Past and future dynamics of the Brunt Ice Shelf from seabed bathymetry and ice shelf geometry [PDF]

The Cryosphere, 2019
The recent rapid growth of rifts in the Brunt Ice Shelf appears to signal the onset of its largest calving event since records began in 1915. The aim of this study is to determine whether this calving event will lead to a new steady state in which the ...

Ocean wave blocking by periodic surface rolls fortifies Arctic ice shelves

Journal of Glaciology, 2023
The Ward Hunt and Milne ice shelves are the present-day remnants of a much larger ice shelf that once fringed the coast of Ellesmere Island, Canada. These ice shelves possess a unique surface morphology consisting of wave-like rolls that run parallel to ...

Southern Ocean warming: Increase in basal melting and grounded ice loss [PDF]

, 2013
We apply a global finite element sea ice/ice shelf/ocean model (FESOM) to the Antarctic marginal seas to analyze projections of ice shelf basal melting in a warmer climate.

Flow and retreat of the Late Quaternary Pine Island-Thwaites palaeo-ice stream, West Antarctica [PDF]

, 2010
Multibeam swath bathymetry and sub-bottom profiler data are used to establish constraints on the flow and retreat history of a major palaeo-ice stream that carried the combined discharge from the parts of the West Antarctic Ice Sheet now occupied by the ...
