Central Chile has been facing a long dry period since 2010, marked by a high mean precipitation deficit, a so-called Mega Drought (MD) (Garreaud et al., 2019). This, besides long-term temperature increase (Burger et al., 2018; Falvey & Garreaud, 2009), has affected negatively the glaciers’ mass balance in the region mainly due to low snow accumulation throughout a hydrological year (which is f ...[Read More]

Women of Cryo VI: Women and Glaciers in the Chilean Andes (Part II)

In Chile, gender imbalance in science mirrors the international context, even though the Americas have been recognised as a region where women’s representation in science has increased, compared to other countries (UNESCO 2015 statistics and this study). However, Chile still has one of the lowest ratios of women participating in STEM (33.1%), followed by Mexico and Peru, as shown in this study. In ...[Read More]

Seafloor secrets: traces of the past Patagonian ice sheet

November 27, 2020

Today’s Patagonian ice caps are confined to the high-altitude Andean Mountain range as the Northern and Southern Patagonia ice fields, and they are rapidly melting. The southern part of the Patagonian ice cap drains partially through fast-flowing ice streams into the fjords of Patagonia. Glaciers in this region have been losing ice at accelerating rates by large calving events, due to rising globa ...[Read More]

When you hear of Chilean glaciers, you probably think about the large glaciers of Patagonia. However, glaciers can be found further north in Chile as well (see this previous post). While the melting of the Patagonian glaciers mainly affects the global human population by contributing to sea level rise, the retreat of glaciers in central Chile affects the local human population directly in terms of ...[Read More]

Did you know… the Andes are so cryo-diverse?

June 19, 2020

Extending for almost 8,000 km along the west of South America, the Andes are the longest continental mountain range in the world. They portray an impressive richness and diversity of cryospheric features, including: the most substantial extension of tropical glaciers on Earth, one of the highest densities of rock glaciers, the largest glacierized area in the Southern Hemisphere outside Antarctica, ...[Read More]
