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


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

Early Results: Juno at Jupiter 

Early results from Juno's mission at Jupiter including approach to Jupiter and the first perijove pass (PJ1). Juno's scientific objectives include the study of Jupiter's interior, atmosphere and polar magnetosphere with the goal of understanding Jupiter's origin, formation and evolution. This collection of papers provides early results from Juno's measurements of the gravity and magnetic fields, deep atmospheric microwave sounding, infrared, visible and ultraviolet images/spectra and an array of fields and particles instruments as well as context for the early results with respect to current theory and models of Jupiter's formation and evolution. Topics include both Juno - Jupiter related theoretical models and data analysis as well as collaborative observations made from Earth based assets.
