The Upsala Glacier is the third largest glacier in the Southern Patagonian Ice Field. Many glaciers in the Patagonian Ice Field, including Upsala, have been retreating over the last 50 years owing to rising temperatures.
Earth observing satellites, including the Copernicus Sentinel-2 mission, have been closely monitoring the Upsala Glacier and have revealed that it has retreated approximately 9 km between 1985 and 2021. Satellite data can help monitor changes in glacier mass and, subsequently, their contribution to rising sea levels.
