Very impressive was the change in surface condition since the deployment of the instruments. At that time the surface was more or less even and the nearest melt lake or river some hundred meters away. During these five years, they moved with the glacier through the ablation zone, which is the part of the glacier where the surface melt is greater than the snow accumulation. The glacier experienced some massive summer melt, so that rivers and lakes are now in their direct vicinity. One of the instruments did not survive that. While it sent regular emails until end of June that all is ok, just before our visit it drowned. The electronic did not survive this, but the memory cards still contain all data! We were really lucky that we arrived only few days later. The other instruments were either upside down or tipped over, but we were able to get them a quick makeover and get them running again – as long as it will be possible in such extreme conditions. Now we are very curious to see what we will learn from the processed data.
