Marie-Louise Siggaard-Andersen

Marie-Louise Siggaard-Andersen is a Senior Researcher at the Section for Geogenetics within the Globe Institute at the University of Copenhagen. Her research focuses on paleoclimate reconstruction using geological archives, with particular expertise in ice core chronology, glacial history, and Quaternary stratigraphy. She maintains an active research profile with recent publications spanning volcanic tephra studies, Greenland ice sheet dynamics, and Arctic climate evolution.

Her research interests center on Quaternary climate variability, glacial-interglacial transitions, and geochronological methods. Siggaard-Andersen specializes in multi-proxy analysis of ice cores, sediment records, and volcanic ash layers to reconstruct past environmental conditions. Her work frequently employs

• X-ray fluorescence (XRF) core scanning
• Ice core aerosol chemistry
• Glacio-isostatic modeling
• Tephrostratigraphic correlation
• Neoglacial glacier chronologies

to address fundamental questions about Arctic climate sensitivity.

Analysis of her recent publications reveals strong emphasis on Greenland ice core chronology development, volcanic forcing of climate, and response of Arctic ice masses to Holocene cooling events. Her collaborative work spans Iceland, Svalbard, and Greenland, demonstrating international leadership in paleoenvironmental reconstruction. While no specific awards are listed in available materials, her research appears in high-impact journals including Quaternary Science Reviews and Earth-System Science Data.
