Assoc. Prof. Bassis quoted in Scientific American article on Antarctic glacier breakup
Assoc. Prof. Jeremy Bassis is quoted in a new Scientific American‚Äč article discussing the role of the submerged rock features on the ocean floor in the breakup of the Antarctic's Pine Island Glacier. ‚ÄčThe glacier is the considered the largest Antarctic contributor to global sea-level rise, thanks to the enormous amount of ice it has lost in recent decades. 
 
From the article: 
 
"...scientists have identified the likely cause of some of the glacier’s most spectacular calving events, which have birthed icebergs several times the size of Manhattan.
 
"The culprit: submerged rock ridges that poke up high enough to occasionally hit the bottom of the glacier. This activity creates small cracks that grow and eventually cause massive chunks of ice to break off. But the undersea rocks are not all bad news—they can also help stabilize the glacier by grinding against its underside, buttressing it against flowing faster out to sea."
