Bands of extra-tough ice slow down cracks in Antarctica’s Larsen C ice shelf

Blog—

The stability of the Antarctic Peninsula’s largest ice shelf may depend upon stripes of extremely strong ice running down its spine, a new study finds.

New research shows rifts in the Larsen C ice shelf tend to stop when they hit parts of the ice known as suture zones. Suture zones are bands of ice several kilometers wide running from the grounding line out to sea that are made of ice from different glaciers and sea water that have frozen together.

The new study finds the large crack currently winding its way across Larsen C takes much longer to punch through suture zones than through other types of ice, meaning these zones are far more important in holding ice shelves together than previously thought, according to the authors…more

A Census of Atmospheric Variability from Seconds to Decades 

The atmosphere varies naturally on all length scales from millimeters to thousands of kilometers, and on all time scales from seconds to decades and longer.  This special collection of Geophysical Research Letters synthesizes and summarizes that variability through a phenomenological census.  The collection brings together some of the most influential and definitive papers to have been published in this journal in recent years.  The topics covered include turbulence on time scales of seconds and minutes, gravity waves on time scales of hours, weather systems on time scales of days, atmospheric blocking on time scales of weeks, the Madden–Julian Oscillation on time scales of months, the Quasi-Biennial Oscillation and El Niño–Southern Oscillation on time scales of years, and the North Atlantic, Arctic, Antarctic, Pacific Decadal, and Atlantic Multi-decadal Oscillations on time scales of decades.  The collection is accompanied by a Commentary article, which provides an authoritative, concise, and accessible point of reference for the most important modes of atmospheric variability.
