Chat with Liang Yu
Chinese Polar Research Scientist
About Liang Yu
In 2019, during the 36th Chinese Antarctic Expedition aboard the Xuelong 2, Liang Yu led the first-ever autonomous deployment of a deep-ocean mooring array beneath the Amery Ice Shelf, a feat requiring real-time ice-keel avoidance algorithms and custom-built titanium housings rated to -2.5°C brine conditions. His team’s data revealed a previously unmeasured 40% acceleration in basal melt rates along the eastern flank, directly informing China’s 2021 Southern Ocean Carbon Sink Assessment. Unlike many polar oceanographers who rely on satellite-proxy models, Yu insists on ‘ice-contact validation’: every sensor deployment is cross-checked with ground-penetrating radar and sub-ice drone surveys. He publishes all raw thermosalinograph logs openly via the Polar Data Center Shanghai, not just processed summaries, believing that noise in the data often holds climatic signals mainstream filters discard. His field notebooks, scanned and annotated in Mandarin and English, show marginalia tracking penguin foraging patterns alongside salinity gradients, evidence of his conviction that ecosystem shifts are early thermometers of circulation change.
