The climate in the Arctic region once predictably shifted back and forth between two regimes. But now the system seems to be stuck.
Greenlanders are well away of piteraqs, the hazardous torrents of cold air that sweep down off the ice cap. But scientists are just beginning to unravel how and when piteraqs form.
Graduate student Laura Stevens became a focal point of a research team that cracked a big mystery atop the Greenland Ice Sheet.
Oceanographers are always looking for cost-effective vehicles to help them explore risky regions. Scientists at WHOI have developed one: a robotic platform called the Jetyak.
WHOI scientists knowingly put a mooring in a fjord filled with icebergs near the terminus of a Greeland glacier. But it was their only way to learn if changing ocean conditions might be affecting how fast the glacier flowed into the ocean.
