Ross Ice Shelf in situ radio-frequency ice attenuation [PDF]
J.Glaciol.57:61-66,2011, 2010 We have measured the in situ average electric field attenuation length for radio-frequency signals broadcast vertically through the Ross Ice Shelf. We chose a location, Moore Embayment, south of Minna Bluff, known for its high reflectivity at the ice-sea interface.

Journal of Glaciology, 1950 Description of that part of the Larsen Shelf Ice traversed by the author when taking part in a sledging expedition which reached lat. 74° 42′ S., manned jointly by members of the Falkland Islands Dependencies Survey and the Ronne Antarctic Research Expedition 1946–48.

The Effects of Rotation and Ice Shelf Topography on Frazil-Laden Ice Shelf Water Plumes [PDF]
Journal of Physical Oceanography, 2006 Abstract A model of the dynamics and thermodynamics of a plume of meltwater at the base of an ice shelf is presented. Such ice shelf water plumes may become supercooled and deposit marine ice if they rise (because of the pressure decrease in the in situ freezing temperature), so the model incorporates both melting and freezing at the ice

History of the Larsen C Ice Shelf reconstructed from sub–ice shelf and offshore sediments [PDF]
Geology, 2021 Abstract Because ice shelves respond to climatic forcing over a range of time scales, from years to millennia, an understanding of their long-term history is critically needed for predicting their future evolution. We present the first detailed reconstruction of the Larsen C Ice Shelf (LCIS), eastern Antarctic Peninsula (AP), based on ...

Ice‐Front Retreat Controls on Ocean Dynamics Under Larsen C Ice Shelf, Antarctica
Geophysical Research Letters, 2023 Iceberg A‐68 separated from the Larsen C Ice Shelf in July 2017 and the impact of this event on the local ocean circulation has yet to be assessed.

A thin plate approximation for ocean wave interactions with an ice shelf [PDF]
arXiv, 2023 A variational principle is proposed to derive the governing equations for the problem of ocean wave interactions with a floating ice shelf, where the ice shelf is modelled by the full linear equations of elasticity and has an Archimedean draught. The variational principle is used to form a thin-plate approximation for the ice shelf, which includes ...

Ice Shelf Water plume flow beneath Filchner‐Ronne Ice Shelf, Antarctica [PDF]
Journal of Geophysical Research: Oceans, 2007 A two‐dimensional plume model is used to study the interaction between Filchner‐Ronne Ice Shelf, Antarctica and its underlying ocean cavity. Ice Shelf Water (ISW) plumes are initiated by the freshwater released from a melting ice shelf and, if they rise, may become supercooled and deposit marine ice due to the pressure increase in the in situ freezing ...

Journal of Advances in Modeling Earth Systems, 2022 The processes responsible for freshwater flux from the Antarctic Ice Sheet (AIS), ice‐shelf basal melting and iceberg calving, are generally poorly represented in current Earth System Models (ESMs).

Energetics of Eddy-Mean Flow Interactions in the Amery Ice Shelf Cavity
Frontiers in Marine Science, 2021 Previous studies demonstrated that eddy processes play an important role in ice shelf basal melting and the water mass properties of ice shelf cavities.

Calving cycle of the Brunt Ice Shelf, Antarctica, driven by changes in ice-shelf geometry [PDF]
The Cryosphere, 2019 Abstract. Despite the potentially detrimental impact of large-scale calving events on the geometry and ice flow of the Antarctic Ice Sheet, little is known about the processes that drive rift formation prior to calving, or what controls the timing of these events.
