This research project aims at studying how wind patterns in the Southern Hemisphere impact the global climate, particularly through their effect on ocean circulation and atmospheric carbon dioxide (CO 2) levels. Southern South America (Patagonia) is one of the only landmass which lies in the path of these winds, providing a unique opportunity to understand how shifts in wind patterns have influenced the Earth`s climate over time. The focus of this research is the Madre de Dios archipelago in southern Chile, a remote and climate-sensitive area located within the southern westerly wind belt. By analyzing ancient climate records preserved in natural formations like stalagmites in cave and lake sediments in this region, scientists aim to uncover valuable information about past climate changes, particularly during the transition from the last Ice Age to the present (known as the Late Glacial to Holocene periods). This combined approach offers a detailed and long-term view of how climate patterns in this area have evolved over thousands of years, contributing to our understanding of global climate dynamics.
