Paleo-Ice Streams and Ice Stream Boundaries, Ross Sea, Antarctica
1997During 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

Streaming flexoelectricity in saline ice
Nature MaterialsDespite 10% of the Earth's surface being covered by ice, ice power remains untapped. Although ice is known to generate electricity upon bending via flexoelectricity1, the generated electric polarization per curvature, that is, the flexoelectric coefficient, is too small (~1-10 nC m-1) to be utilized for electromechanical devices.

Demultiplexer IC for MPEG2 transport streams
IEEE Transactions on Consumer Electronics, 1995The 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 ...

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 ...

A palaeo-ice stream of the British Ice Sheet in eastern Scotland
Boreas, 2006Terrestrial 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 ...

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 ...
