Frontier Scientists: presenting scientific discovery in the Arctic and beyond
Sniffing The Arctic — Warming Arctic temperatures, sea ice changes, and upsets in atmospheric trends can alter the jet stream and impact weather systems in North America. Now through new advances in isotope science we can sniff Arctic air to better quantify water cycle changes and their impacts. For the past 20 years Dr. Jeff Welker, a... Read More >
