Abstract/Description
This study aims to investigate seasonal stratigraphy in ice cores extracted from mountain glaciers and assess limitations in reconstructing past seasonality and dust/emission events. While temperate glaciers often show diffuse stratigraphy due to summer melt, seasonal signals can still be preserved with high accumulation rates (Neff, 2017). Research for mountain ice cores has been concentrated in regions such as Alaska, Yukon, and the Alps, but this study seeks to expand investigations to Patagonia, where sites are currently being evaluated.
As a developing PhD proposal, this research is expected to refine its objectives over the coming months. Mountain ice cores offer critical insights into past regional climate variability while also helping to project future changes. Given that 1.9 billion people worldwide rely on glacier-fed water sources (WMO, 2025), assessing the rate of glacial change is of utmost importance. The Andes, an underrepresented region in ice core studies, presents a unique and urgent opportunity for investigation.
