Hernán Sala: glacier melt from a satellite perspective 

 

This year, from the 7th July up to the 11th August, I have performed a very productive stay in the Center for Remote Sensing of Land Surfaces (ZFL) at Bonn University.

During my stay, I have worked with my colleagues Ulrike Falk (Univ. of Bonn), Adrián Silva Busso (Instituto Nacional del Agua from Argentina) and Damián López (Univ. of Bonn/Univ. of Cologne). We have also been in close contact with Matthias Braun from Erlangen-Nuremberg University (FAU).

During my stay at  the ZFL, we have been processing and analyzing data that we have collected in different summer campaigns at Carlini Station, 25 de Mayo - King George Island, Antarctica. Our data include air and soil temperatures, geoelectrical vertical soundings, conductivity and redox properties of samples taken from streams nourished by glacier and permafrost melting, and also from frequent local precipitation of rain and snow, etc.

We have also been comparing the data that we have collected with publicly available datasets or model outputs and satellite imagery with the aim of having a broader picture that can be extended to the northern tip of the Antarctic Peninsula.

This stay has been a very good opportunity to work together because. We have met again as the same team that has been working in Antarctica just a few years ago.

Of course, we have also enjoyed very much the sun and the warm days having nice bike rides and walks in Bonn and its surroundings.

I would like to express my gratitude to my colleagues in Germany and Argentina for such a productive and enjoyable stay in Bonn, and for making me feel at home.

Also, I would like to give my thanks to the IMCONet Project and the associated institutions at Germany (AWI, FAU and ZFL) and Argentina (IAA-DNA). Without their support this highly motivating and pleasant experience abroad would not have been possible.
