Torge Martin

Dr. Torge Martin serves as a Senior Scientist in Ocean Dynamics at the GEOMAR Helmholtz Centre for Ocean Research Kiel, where he is actively engaged in research on ocean circulation and climate dynamics. His work focuses on polar climate systems with particular emphasis on the interactions between ice sheets, oceans, and atmosphere in both the Arctic and Antarctic regions. As a member of the GEOMAR scientific council and student advisor in physical oceanography, he contributes significantly to institutional governance and academic training.

Dr. Martin's research interests center on physical processes driving marine climate variability in high-latitude regions. He investigates how melting ice sheets impact ocean circulation patterns, with special attention to the role of mesoscale eddies (10-100km) in redistributing heat and freshwater. His work explores the connections between surface changes and deep ocean variability, particularly examining how rapid ice melt translates into changes in the Atlantic Meridional Overturning Circulation. He is deeply involved in high-resolution ocean and coupled climate modeling, developing and applying the Flexible Ocean and Climate Infrastructure (FOCI) with regional refinement capabilities to study ice-ocean-atmosphere interactions at multiple scales.

The analysis of Dr. Martin's recent publications reveals a consistent focus on polar ocean dynamics and climate change impacts. His work spans from Arctic sea ice dynamics to Southern Ocean circulation, with particular emphasis on how freshwater input from melting ice sheets affects ocean circulation patterns. The research employs advanced modeling techniques, often incorporating mesoscale resolution to capture critical ocean processes. A significant portion of his recent work contributes to the Southern Ocean Freshwater Input from Antarctica (SOFIA) initiative, examining multi-model responses to Antarctic meltwater.

Dr. Martin actively mentors students in physical oceanography and has developed innovative teaching approaches using rotating tank experiments to demonstrate ocean dynamics principles. His research is supported through multiple projects including SCENIC (Storyline Scenarios of Extreme Weather), G-shocx (Greenland Ice Sheet–melting exiting ocean extremes), PalMod Phase 2, and the Flexible Ocean and Climate Infrastructure (FOCI) development. He chairs sessions at major international conferences including EGU General Assembly and Ocean Sciences Meeting, and has served as co-chair of the Southern Ocean Region Panel (SORP) of CLIVAR, CliC and SCAR from 2020 to 2023. His laboratory work centers on high-resolution ocean modeling with the FOCI climate model, featuring regional refinement capabilities for the subpolar North Atlantic (VIKING10) and Southern Ocean (ORION10X), allowing explicit simulation of mesoscale dynamics critical to understanding polar climate processes.
