The Rwenzori Mountains (Uganda).

This project is an art-science collaboration with Ian van Coller (photographer & professor @ Montana State) and Todd Anderson (print maker and professor, Clemson University).

The Quelccaya Ice Cap (Peru).

The Quelccaya Ice Cap (Peru) is the largest glacier in the Tropics, located at over 5,200 m in the Cordillera Vilcanota. We have collected in-situ GPS positions of the ice margin for over 15 years and are compiling the data into a comprehensive web-based GIS of the ice cap in combination with satellite images.

The Disappearance of Glaciers in Venezuela.

This study asked a simple question: What is the state of glaciers in Venezuela today? The answer is not as obvious as it seems – the glaciers in Venezuela have been literally forgotten in terms of scientific research since the early 1990s. The answer is provided in this project through an extensive compilation of the available scientific literature, maps, and historical photographs that document the recession of glaciers in Venezuela since the start of the 20th century. Climate data analysis and glacier mapping in 2009 and 2011 provide the modern context and the study was published as Braun and Bezada (2013).

I am currently extending the record using additional field measurements from 2015 and new Landsat 8 / Sentinel 2 satellite images to create a comprehensive web-based GIS of the glaciers in Venezuela.

Canadian High Arctic / Ellesmere Island.

My research in the Canadian High Arctic focused on the mass balance of glaciers, ice caps, and ice shelves. Specifically, I am interested (a) in the processes affecting the ice shelves and ice rises along the northern coast of Ellesmere Island and the mechanisms responsible for their recent collapses and (b) the processes involved in the formation and disappearance of the small Hazen Plateau ice caps.
