February 7, 2013 | NASA

“In a clever reuse of hardware originally built to test parts of NASA’s QuikScat satellite, the agency will launch the ISS-RapidScat instrument to the International Space Station in 2014 to measure ocean surface wind speed and direction.” Quoted from the NASA press release.

Measuring Wind With Microphones?
March 2, 2014 | University of Colorado Boulder
"We have demonstrated for the first time that we can use ambient noise to measure wind speeds. [...] Eventually, the method could be used to cheaply measure wind speed and direction in the atmosphere, critical information for weather forecasts, or even to study the rotation of Earth’s core." Quoted from the University of Colorado Boulder press release.

Enormous Ice Sheets Scoured the Arctic Ocean Floor
October 11, 2013 | Alfred Wegener Institute
"We knew of such scour marks from places like the Antarctic and Greenland. They arise when large ice sheets become grounded on the ocean floor and then scrape over the ground like a plane with dozens of blades as they flow. The remarkable feature of our new map is that it indicates very accurately right off that there were four or more generations of ice masses, which in the past 800,000 years moved from the East Siberian Sea in a north-easterly direction far into the deep Artic Ocean." Quoted from the Alfred Wegener Institute press release.
