线上腾讯会议ID：540 984 288
Dr. Z. George Xue (薛佐) is an Associate Professor (with tenure) at the Dept. of Oceanography and Coastal Sciences at Louisiana State University (LSU) with a joint appointment at LSU’s Center for Computation and Technology. Over the past 15 years, Dr. Xue’s research focused on the sediments, nutrients, and carbon dynamics and cycling in the Mississippi-Gulf of Mexico as well as Mekong-South China Sea systems. Dr. Xue has published over 50 papers and served as reviewer for a wide range of high impact journals including Biogeosciences, JGR, Marine Geology, Estuary, Coast, and Shelf Sciences. Currently Dr. Xue’s research group has 4 Ph.D. and 1 M.S. students working on different topics including hypoxia, compound flooding, carbon cycling, air-sea interaction, sedimentation using coupled numerical modeling techniques. Since 2014, Dr. Xue has secured over $ 6 million extramural funding to LSU from various federal and state agencies, with over $3 million as leading PI. Dr. Xue received Phi Kappa Phi Non-Tenured Achievement Award in 2018 and LSU Alumni Association Rising Faculty Research Award in 2019.
The Gulf of Mexico is suffering various coastal hazards including sea-level rise, coastal erosion and land loss, hurricanes, compound flooding, hypoxia, and ocean acidification. In this seminar, I will demonstrate how processes of different spatial and temporal scale could be reproduced using two sets of state-of-the-art community modeling suites: The Coupled Ocean Wave and Sediment Transport Modeling System (COAWST) and Weather Research Forecasting Model Hydrological Extension (WRF-Hydro) as well as the coupling between them. I will present several novel model developments in my research group and show applications on both short- and long-term disturbances in the coastal ocean. The time scale of these case studies ranges from days to decadal, and the topics covers sediment transport, coastal erosion, tropical cyclones, compound flooding, hypoxia, and carbon cycling. These results shed lights on the potential of an integrated regional modeling system to solve the complex processes at the land-ocean interaction zone facing a changing climate and ever-increasing human activities.
