PATICE: The Patagonian Ice Sheet from 35,000 years ago to the present day This page provides a brand-new reconstruction of the Patagonian Ice Sheet from 35,000 years ago to the present day (called PATICE). PATICE is a new compilation of published ages and geomorphology, ranked and assessed and recalibrated, which we use to generate new …

The Patagonian Icefields today

Geographic setting Patagonia, between ~40°S to 56°S, is the most southerly part of the South American continent. The landscape of this region is one of contrasts. Dense temperate rainforests cover the western coast, whereas the eastern plains are flat, vast, and arid. Perhaps most striking, however, are the high, Patagonian Andes, which rise steeply (up …

Patagonian Ice Sheet at the LGM

What was the former Patagonian Ice Sheet? The Patagonian Ice Sheet was a large, elongated mountain ice mass that developed over the Andes mountains of southern South America during cold periods[1]. The Patagonian Ice Sheet has advanced and retreated at least 5 times in the last million years[2] in response to changes in global climate (i.e. …

Patagonian Ice Sheet

This page summarises some of our recent research on the dynamics of Patagonian outlet glaciers during the Last Glacial Maximum and following deglaciation. Pages on glacial landforms are especially relevant to the Geography A-Level curriculum. Here, you can watch a seminar I gave about the Patagonian Ice Sheet:   Further reading: Shrinking Patagonian Glaciers Patagonian …

Drumlins

Drumlins around Lago Viedma Although the Patagonian Icefields aren’t generally associated with drumlins (Glasser et al., 2008), there are some around Lago Viedma in the South Patagonian Icefield. They have been described in detail (Ponce et al., 2013) but they show up beautifully in the Landsat map below. The mapping below is by me (Bethan …
