The Petermann Ice Shelf Estuary and its impact on ice-shelf stability
2020<p>In a warming world, increased meltwater will form on Antarctica&#8217;s ice shelves. The fate of this meltwater will be critical to future ice-shelf and ice-sheet stability. Two main observations define the current theoretical framework for understanding the influence of surface hydrology on ice-shelf stability.

Ross Ice Shelf temperatures support a history of ice-shelf thickening
Nature, 1979The ice sheet in West Antarctica is grounded on a sub-sea level basin in the Antarctic continental shelf. At the seaward margins, where ice thicknesses are reduced sufficiently to attain neutral bouyancy, floating ice shelves form. The two largest are the Ross and Ronne ice shelves (Fig. 1).

Abstract A two-dimensional analysis which neglects profile variation in a lateral direction is presented for a floating viscous ice shelf. It applies to plane flow and to unconfined flow which is within short distances of the symmetry line. It is shown that surface variation can, in time, make a significant contribution to the balance, and yet be too

GEOLOGY Several small ice shelves around the Antarctic Peninsula retreated during the late 20th century due to regional climate warming. Did similar retreats occur through natural climate variability during the past 10,000 years. Pudsey and Evans have now addressed this question by studying the history of the Prince Gustav Channel ice shelf.

A Predictive Theory For Heat Transport Into Ice Shelf Into Ice Shelf CavitiesÂ
Antarctic ice shelves are losing mass at drastically different rates, primarily due to differing rates of oceanic heat supply to their bases. However, a generalized theory for the inflow of relatively warm water into ice shelf cavities is lacking.Garrett Finucane, Andrew Stewart

Faunal Remains on an Antarctic Ice Shelf
Science, 1961Fishes and benthic invertebrates discovered frozen in situ and exposed at the ablation surface of the McMurdo ice shelf provide evidence both for the occurrence of a fauna, including large fishes, under the permanent ice shelf and for Debenham's hypothesis of the nourishment of an ice shelf by the freezing of sea ...

Large ice masses such as ice sheets and ice shelves change as the Earth's climate changes, and can serve as indicators of past climate variation. In his Perspective, Fahnestock discusses observations reported by Rott et al. in the same issue, which show the dramatic collapse

INTRODUCTION Of all Antarctic glacial features, none is as characteristic or as distinctive and none has excited as much interest and as much speculation from explorers, as the areas of shelf ice which occupy protected or partly protected areas about the continent. The best known and largest of these is the Ross Shelf Ice, which extends northward from
