Daryl Chen (PhD Student)
Congratulations to Daryl J. Chen, Ph.D. student in Geography, on the publication of his article, Differential Temperature Controls on Spring Freshet Onset Timing in the Upper Kuskokwim River Basin in Alaska, co-authored with Wonsun Choi and published in 기후연구. The study found that spring freshet in Alaska’s Upper Kuskokwim River Basin has shifted significantly earlier over the past four decades and is closely linked to spring temperature conditions. We congratulate Daryl on this excellent contribution to climate and hydrological research.
