About Yanling Yu Dr. Yu investigates arctic sea ice and its role in the Arctic climate and ocean circulation. Analyzing submarine observations, she and her colleagues examine the long-term changes in mean ice thickness and its distribution. She also uses dynamic and thermodynamic models and statistic methods to search for clues as to why some changes have occurred and how these changes can be characterized in both space and time. She has developed an algorithm to derive arctic thin ice thickness by combining a thermodynamic sea ice model with the satellite observations from Advanced Very High Resolution Radiometer (AVHRR) imagery. This algorithm can be used to study the aggregated sea ice properties dependent on thin ice thickness distribution, such as brine flux from growing young ice and large-scale ice strength. Under the NSF funded Arctic Freshwater Initiative, Dr. Yu and her colleagues will investigate the interannual variability of arctic landfast ice and its contribution to the freshwater budget on the arctic shelves. She has published several research papers in geophysical journals. She joined PSC after receiving her Ph.D in Physical Oceanography from the School of Oceanography, University of Washington.
