Yucheng Lin is a postdoctoral researcher at Rutgers University. His research examines different physical processes impact on sea-level change in the past and future under changing climate. He focuses on developing novel physical and statistical tools to better understand the mechanisms that drive spatio-temporal variability of sea-level change, which can be used to produce more accurate and robust sea-level projections.

Calculating postglacial sea-level change within few seconds: a statistical emulator for GIA

Sea-level change serves as a direct indicator of climate change with profound implications for coastal areas. Since 1900, the global mean sea level (GMSL) has risen over 20 cm, leading to beach erosion, delta inundation, and increased flooding worldwide. Over glacial cycles spanning tens of thousands of years, interactions between ocean and continental-scale ice sheets can cause GMSL to fluctuate ...[Read More]

As the Geodesy blog team (we are growing, horaay!), we wanted to create a space for researchers to talk about their work/papers in a more simplified language. For the first post in this series, we said “Wouldn’t it be cool if we learn more about Glacial Isostatic Adjustment (GIA) models?” then we realised that we first need to uncover what GIA is. So, we passed the pen to Holger, Rebekka and Yuche ...[Read More]
