A Wedge Mechanism for Summer Surface Water Inflow Into the Ross Ice Shelf Cavity

open access: yesJournal of Geophysical Research: Oceans, 2019
Ocean heat supply to ice shelves has a significant impact on the long‐term evolution of ice shelves. Intrusions of warm surface waters into the frontal region of the cavity, known as “Mode 3” circulation, are capable of melting the ice shelf base ...

Stability of the Junction of an Ice Sheet and an Ice Shelf [PDF]

open access: yesJournal of Glaciology, 1974
An analysis is made of the steady-state size of a two-dimensional ice sheet whose base is below sea-level and which terminates in floating ice shelves. Under the assumption of perfect plasticity it is found that an ice sheet placed on a bed whose surface was initially flat cannot exist if the depth of the bed below sea-level exceeds a critical depth ...

Melting and freezing under Antarctic ice shelves from a combination of ice-sheet modelling and observations

open access: yesJournal of Glaciology, 2017
Ice-shelf basal melting is the largest contributor to the negative mass balance of the Antarctic ice sheet. However, current implementations of ice/ocean interactions in ice-sheet models disagree with the distribution of sub-shelf melt and freezing rates

Spatial and temporal variations in basal melting at Nivlisen ice shelf, East Antarctica, derived from phase-sensitive radars

open access: yesThe Cryosphere, 2019
. Thinning rates of ice shelves vary widely around Antarctica, and basal melting is a major component of ice shelf mass loss. In this study, we present records of basal melting at a unique spatial and temporal resolution for East Antarctica, derived from

Oceanographic observations at the Amundsen sea shelf break [PDF]

open access: yes, 2004
Introduction: The continental shelf environment of the Amundsen and Bellingshausen seas differs markedly from that of the other circumpolar seas, where water temperatures are close to the surface freezing point throughout.

Ross Ice Shelf Displacement and Elastic Plate Waves Induced by Whillans Ice Stream Slip Events

open access: yesGeophysical Research Letters
Ice shelves are assumed to flow steadily from their grounding lines to the ice front. We report the detection of ice‐propagating extensional Lamb (plate) waves accompanied by pulses of permanent ice shelf displacement observed by co‐located Global ...
