Journal of Glaciology, 2016 The dominant mass-loss process on the Antarctic Peninsula has been ice-shelf collapse, including the Larsen A Ice Shelf in early 1995. Following this collapse, there was rapid speed up and thinning of its tributary glaciers.

The Cryosphere, 2019 . Ocean-induced basal melting is responsible for much of the Amundsen Sea Embayment ice loss in recent decades, but the total magnitude and spatiotemporal evolution of this melt is poorly constrained.

The MOSAiC ice floe: sediment-laden survivor from the Siberian shelf
The Cryosphere, 2020 . In September 2019, the research icebreaker Polarstern started the largest multidisciplinary Arctic expedition to date, the MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) drift experiment. Being moored to an ice floe for

Centurial‐millenial ice‐rafted debris pulses from ablating marine ice sheets [PDF]
, 2001 We use an ice‐sheet model to show that (i) margins of marine ice‐sheets can be expected to be frozen to the bed, except where ice‐streams discharge; (ii) 20–50km retreats induced by ablation rates of 2 m/yr provide sufficient debris flux through the ...

Direct measurements of ice-shelf flexure caused by surface meltwater ponding and drainage
Nature Communications, 2019 Global sea-level rise is caused, in part, by more rapid ice discharge from Antarctica, following the removal of the restraining forces of floating ice-shelves after their break-up.

Brine, englacial structure and basal properties near the terminus of McMurdo Ice Shelf, Antarctica
Annals of Glaciology, 2017 We collected ~1300 km of ground-penetrating radar profiles over McMurdo Ice Shelf, Antarctica, using frequencies between 40 and 400 MHz to determine extent, continuity and depth to the brine.

A Speed Limit on Ice Shelf Collapse Through Hydrofracture
Geophysical Research Letters, 2019 Increasing surface melt has been implicated in the collapse of several Antarctic ice shelves over the last few decades, including the collapse of Larsen B Ice Shelf over a period of just a few weeks in 2002.

Tidal bending of ice shelves as a mechanism for large-scale temporal variations in ice flow [PDF]
, 2018 GPS measurements reveal strong modulation of horizontal ice shelf and ice stream flow at a variety of tidal frequencies, most notably a fortnightly (Msf) frequency not present in the vertical tides themselves. Current theories largely fail to explain the

How Accurately Should We Model Ice Shelf Melt Rates?
Geophysical Research Letters, 2019 Assessment of ocean‐forced ice sheet loss requires that ocean models be able to represent sub‐ice shelf melt rates. However, spatial accuracy of modeled melt is not well investigated, and neither is the level of accuracy required to assess ice sheet loss.
