The aims of this review are to:(a) describe and interpret structures in valley glaciers in
relation to strain history; and (b) to explore how these structures inform our understanding of …

Abstract The Radar for Europa Assessment and Sounding: Ocean to Near-surface
(REASON) is a dual-frequency ice-penetrating radar (9 and 60 MHz) onboard the Europa …

A dense grid of ice‐penetrating radar sections acquired over Pine Island Glacier, West
Antarctica has revealed a network of sinuous subglacial channels, typically 500 m to 3 km …

Antarctica's subglacial lakes have two end member geophysical expressions: as
hydraulically flat, radar reflective regions highlighted in ice surface topography and radar …

Basal crevasses extend upwards from the base of ice bodies and can penetrate more than
halfway through the ice column under conditions found commonly on ice shelves. As a …

Evidence for extensive crevassing is preserved on the deglaciated forelands of many
surging glaciers as crevasse squeeze ridges (CSRs). At some point these crevasses make …

Recent work has raised the potential for Jupiter's decametric radiation to be used as a
source for passive radio sounding of its icy moons. Two radar sounding instruments, the …

A primary objective of future Europa studies will be to characterize the distribution of shallow
subsurface water as well as to identify any ice-ocean interface. Other objectives will be to …

Comparison of the Ross Ice Shelf (RIS, Antarctica) response at near-front seismic station
RIS2 with seismometer data collected on tabular iceberg B15A and with land-based seismic …

As ice streams flow into the Ross Ice Shelf, West Antarctica, their bed coupling transitions
from weak to transient to zero as the ice goes afloat. Here we explore the nature of the bed …
