Late Glacial and Holocene Glaciation in Tierra del Fuego

In late 2023, this team of four researchers from the University of Edinburgh and Universidad Católica de Chile undertook fieldwork on two islands in Tierra del Fuego. Having sampled 34 quartz-rich rocks deposited by past glacier re-advances on Isla Santa Inés and Isla Grande they intend to date these samples using cosmogenic nuclide exposure dating in order to reconstruct the Late Glacial and Holocene glacial history of the region. This will enable the use of numerical glacier modelling which they hope will offer an understanding of the climate required to drive glacier re-advances.
