Deep learning the flow law of Antarctic ice shelves.

Science
Antarctic ice shelves buttress the grounded ice sheet, mitigating global sea level rise. However, fundamental mechanical properties, such as the ice flow law and viscosity structure, remain under debate.

Stability of Ice Shelves and Ice Cliffs in a Changing Climate

Annual Review of Earth and Planetary Science
The largest uncertainty in future sea-level rise is loss of ice from the Greenland and Antarctic Ice Sheets. Ice shelves, freely floating platforms of ice that fringe the ice sheets, play a crucial role in restraining discharge of grounded ice into the ...

How Does the Ocean Melt Antarctic Ice Shelves?

Annual Review of Marine Science
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 ...

Ice shelves and ice flow

Nature, 1975
New data on the Ross Ice Shelf provide an insight into the importance of the momentum with which an ice stream enters the shelf for the overall velocity field.

Sea ice growth rates near ice shelves

Cold Regions Science and Technology, 2012
Abstract Sea ice growth rates near ice shelves are influenced by ocean-ice shelf interactions. Sea ice growth rates and ocean observations from McMurdo Sound, Antarctica in 1999 and 2000 are presented in this paper. Growth rate measurements were made for an individual platelet crystal through video camera observations.

Microbiota under Antarctic ice shelves

Nature, 1977
WHETHER or not life can exist far from the open sea beneath the permanent ice shelves of Antarctica is not known, but there are three opinions. (1) A biota cannot exist at all because of the absence of surface primary and secondary productivity1. (2) A biota exists but with specialisations unique to life in the absence of surface productivity and in ...

How ice shelves melt

Science, 2014
Warming of the water that flows under Antarctic ice shelves is key to their melting [Also see Report by Schmidtko et al. ]

Greenland Ice Shelves and Ice Tongues

2017
This chapter focuses on a review of the glaciers on north and northeast Greenland that terminate in fiords with long glacier tongues and floating, ice-shelf-like margins. There is some debate as to whether these glacier tongues can be classified as a traditional ice shelf, so the relevant literature and physical properties are reviewed.

Flow Law for Antarctic Ice Shelves

Nature Physical Science, 1971
ICE shelves are floating glaciers which are attached to an inland ice sheet or to land. They creep under their own weight, the creep rates being dependent on the ice flow law at low stresses.
