Abstract
Melt ponds play an important role in glacial surface melt, and are thus important to look into considering projected future sea level rise. As the largest ice mass in the Southern Hemisphere, the Southern Patagonian Icefield (SPI) is a main contributor. To better predict the future, understanding variability in melting and what climatic factors drive it is crucial. However, this is a topic that has not been studied extensively. I used Sentinel-2 satellite imagery of glaciers in the Southern Patagonian Icefield over a period from December 2018 to December 2023 and applied a Random Forest (RF) algorithm to classify melt ponds. I found a large range of variability in melt pond area both comparing between glaciers (with mean relative areas ranging between 0.3% on Pio XI to 1.9% on Upsala), and over time (0%-3.5% relative area). Any seasonality in this area appeared unclear. I found the Southern Annular Mode (SAM) to not have a significant effect on pond area.
