Antarctic ice shelves typically comprise continental meteoric ice, in situ-accumulated meteoric ice, and marine ice accumulated at the shelf base. Using borehole optical televiewer logs from across Larsen C Ice Shelf, Antarctic Peninsula, we identify and report an intermediate ice unit…
The presence and nature of marine ice in ice shelves is important, yet difficult to determine. We present transient electromagnetic results spanning 10 km across a suture zone of Larsen C Ice Shelf (LCIS), Antarctica, supported by central borehole measurements.

Accelerated warming since the 1950s has caused dramatic change to ice shelves and outlet glaciers on the Antarctic Peninsula. Long observational records of ice loss in Antarctica are rare but essential to accurately inform mass balance estimates of glaciers. Here…
As part of the global project ORACLE-O3 selected for the IPY, LOLITA-PSC (“Lagrangian Observations with Lidar Investigations and Trajectories in Antarctica and Arctic, of PSC”) is devoted to Polar Stratospheric Clouds (PSCs) studies. Indeed…
Recent research indicates extensive basal melting near the deep grounding lines of major … Antarctic outlet glaciers. Further…
The collapse of the Larsen A and B and other ice shelves fringing the Antarctic Peninsula … coastline raises questions about the status of ice shelves in other parts of the continent. Are … the large ice shelves along the East Antarctic coast also in danger of permanent collapse…
A method has been developed for the routine determination of four arsenic species (arsenite, arsenate, monomethylarsenic and dimethylarsenic) in natural water, and has been applied to a study of arsenic cycling in open ocean (Atlantic and Southern Ocean) and estuarine (Huon Estuary, Tasmania)…
Break-up of ice shelves has been regarded as an indicator of climate change1. Observations around the Antarctic Peninsula have shown a pattern of gradual retreat, associated with a regional atmospheric warming and increased summer melt and fracturing processes2-9.
