Palaeo-ice streams

Quaternary Science Reviews, 2001
Abstract The location and behaviour of ice streams is one of the most important controls on ice sheet configuration and stability. In order to reconstruct former ice sheets we need to know ice stream location and timing. Once identified, the beds of palaeo-ice streams provide an unprecedented opportunity to glean information about their basal ...

Thermal Weakening, Convergent Flow, and Vertical Heat Transport in the Northeast Greenland Ice Stream Shear Margins

Geophysical Research Letters, 2019
Ice streams are bounded by abrupt transitions in speed called shear margins. Some shear margins are fixed by subglacial topography, but others are thought to be self‐organizing, evolving by thermal feedback to ice viscosity and basal drag which govern ...

Old Ice Streams

Science, 2000
GEOLOGY The size and behavior of past Antarctic ice sheets are essential elements in the quest to understand how and why climate changed in the past and what the consequences may be in the future. Modern observations have shown that Antarctic ice flow is slow and diffuse over most of the interior of the ice sheet but focuses into relatively rapid ...

Paleo-Ice Streams and Ice Stream Boundaries, Ross Sea, Antarctica

1997
During the RVIB Nathaniel B. Palmer 1994–01 and 1995–01 cruises, approximately 7141 km of 50 in3 airgun seismic profiles and 12,150 km of 3.5 kHz trackline data were collected from the Ross Sea continental shelf. Ross Sea is a broad embayment, approximately 1500 km wide and 900 km long, on the Antarctic coast (Fig. 1). Water depths range from less than

Rutford Ice Stream, Antarctica

2013
Rutford Ice Stream is in many ways a typical Antarctic outlet glacier. Constrained by a subglacial-bed trough to the east of the Ellsworth Mountains, it drains an area of 49,000 km2 of the West Antarctic Ice Sheet. Varying in width from 20 to 30 km, flowing fast (up to 400 m/a) for more than 150 km before it starts to float, and over 2000 m thick along

A palaeo-ice stream of the British Ice Sheet in eastern Scotland [PDF]

open access: possibleBoreas, 2006
Terrestrial and marine subglacial landforms in eastern Scotland are used to evaluate previously unsubstantiated notions of ice streaming within the British Ice Sheet (BIS) in this area during the last glacial cycle. Employing both regional and local-scale data sets, we describe onshore landform-sediment assemblages, offshore geomorphology and ...

Laurentide ice streaming on the Canadian Shield: A conflict with the soft-bedded ice stream paradigm?

Geology, 2003
Elucidating the controls on the location and vigor of ice streams is crucial to understanding the processes that lead to fast disintegration of ice flows and ice sheets. In the former North American Laurentide ice sheet, ice stream occurrence appears to have been governed by topographic troughs or areas of soft-sediment geology.

Demultiplexer IC for MPEG2 transport streams

IEEE Transactions on Consumer Electronics, 1995
The MPEG2 systems was adopted as an international standard that specifies the multiplexed structure for combining audio and video data and a means of representing the timing information needed to replay synchronized sequences in real-time. This paper describes an integrated circuit developed to demultiplex desired programmes carried in an MPEG2 ...

Controlling Icings on Small Streams

ISCORD 2013, 2013
Research addressing natural processes and control of ground and river icings is well established in national and international technical literature, particularly for large river flows. However controls applicable to small flow icings are less well documented, providing little guidance for the local engineers who are most often asked to design them.
