Researchers led by Yuko Motizuki from the Astro-Glaciology Laboratory at the RIKEN Nishina Center in Japan have developed a new laser-based sampling system for studying the composition of ice cores taken from glaciers. The new system has a 3-mm depth-resolution—about three times smaller than what is currently available—meaning that it can detect temperature variations that occurred over much smaller periods of time in the past.
