Biography

Dr. Huijie Xue conducts research on ocean circulation, mesoscale eddies, and air-sea interactions at Xiamen University. Her work focuses on marginal seas and their dynamic connection with large-scale boundary current systems such as the Kuroshio. Using high-resolution numerical modeling and observational analyses, she explores key processes including Kuroshio intrusion, vertical overturning circulation in the South China Sea, and salinity-driven monsoon feedback. Her research addresses both the physical mechanisms and their biogeochemical and ecological implications, including how circulation anomalies regulate nutrient transport and primary productivity. Dr. Xue’s work enhances the scientific basis for understanding regional ocean–climate interactions, particularly in western Pacific marginal seas, and contributes to the development of predictive frameworks for marine environmental change and ecosystem response.

Deciphering Mesoscale Eddy-Driven Nutrient Transport in the Indonesian Seas

This study investigates mesoscale eddy-mediated vertical nutrient fluxes in the Indonesia Sea using a high-resolution coupled physical- biogeochemical model. By synthesizing satellite altimetry, glider transects, and Lagrangian float data, we quantify eddy-induced nitrate uplift mechanisms across the zone. Results reveal that anticyclonic eddies enhance sub-surface nitrate entrainment by 18-34% during their westward propagation, disproportionately fueling primary production in nutrient-depleted regions. A novel eddy tracking algorithm identifies "hotspot" eddies responsible for 62% of cross-pycnocline nutrient transport despite representing only 22% of eddy occurrences. These findings advance our capacity to parameterize eddy impacts in climate models.
