Julius Oelsmann is a PhD student from the Deutsches Geodätisches Forschungsinstitut at the Technical University of Munich under the supervision of Prof. Dr. Florian Seitz and Dr. Marcello Passaro. He is investigating the individual components of regional coastal sea level change. Next to climate induced sea level changes, a large proportion of sea level changes relative to the coast arise from coastal subsidence and uplift due to a variety of vertical land motion processes. To determine these individual contributions, he used different observational techniques (coastal altimetry, tide gauges and GNSS), as well as models of ocean and solid earth processes. Based on the observational constraints, he developed a Bayesian vertical land motion reconstruction to estimate its impact on of past and future sea level change. His presentation at the EGU General Assembly 2022 highlights that nonlinear vertical land motion increases previously reported uncertainty limits in coastal relative sea level projections.
