Can rifts alter ocean dynamics beneath ice shelves? [PDF]

The Cryosphere, 2023
Land ice discharge from the Antarctic continent into the ocean is restrained by ice shelves, floating extensions of grounded ice that buttress the glacier outflow.

The distribution and evolution of surface fractures on pan-Antarctic ice shelves

International Journal of Digital Earth, 2023
Surface fractures have a great impact on ice shelf stability in Antarctica and can be considered precursors of ice shelf calving. However, our understanding of the spatial distribution and temporal evolution of surface fractures on the Antarctic ice ...

Explicit representation and parametrised impacts of under ice shelf seas in the z^∗ coordinate ocean model NEMO 3.6 [PDF]

Geoscientific Model Development, 2017
Ice-shelf–ocean interactions are a major source of freshwater on the Antarctic continental shelf and have a strong impact on ocean properties, ocean circulation and sea ice.

Exploring beneath the PIG Ice Shelf with the Autosub3 AUV [PDF]

, 2009
On 31st January 2009, two numbers: “range and bearing” flashing up on a laptop screen, indicated that Autosub3 had returned from its last mission beneath the Pine Island Glacier (PIG) Ice Shelf in the Western Antarctic.

Reconstruction of ice-sheet changes in the Antarctic Peninsula since the Last Glacial Maximum [PDF]

, 2014
This paper compiles and reviews marine and terrestrial data constraining the dimensions and configuration of the Antarctic Peninsula Ice Sheet (APIS) from the Last Glacial Maximum (LGM) through deglaciation to the present day.

The ice dynamic and melting response of Pine Island Ice Shelf to calving [PDF]

, 2022
Sea level rise contributions from the Pine Island Glacier (PIG) are strongly modulated by the backstress that its floating extension – Pine Island Ice Shelf (PIIS) – exerts on the adjoining grounded ice.

Frazil dynamics and precipitation in a water column with depth-dependent supercooling [PDF]

, 2005
When seawater becomes supercooled, collections of small ice crystals, known as frazil ice, form and grow. A model of frazil ice dynamics is presented that deals explicitly with the buoyant settling of frazil crystals onto an overlying surface.

Seasonal inflow of warm water onto the southern Weddell Sea continental shelf, Antarctica [PDF]

, 2012
To capture the austral summer to winter transition in water mass properties over the southern Weddell Sea continental shelf and slope region, 19 Weddell seals were tagged with miniaturized conductivity–temperature–depth sensors in February 2011.

Warm ocean is eroding West Antarctic Ice Sheet [PDF]

, 2004
Satellite radar measurements show that ice shelves in Pine Island Bay have thinned by up to 5.5 m yr^{-1} over the past decade. The pattern of shelf thinning mirrors that of their grounded tributaries-the Pine Island, Thwaites and Smith glaciers- and ...

History of Larsen C Ice Shelf reconstructed from sub-ice shelf and offshore sediments [PDF]

, 2021
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.
