18 October – The outcome

Below is a short summary report of what happened on the Ortler project over the course of the last month.

Between 23 September and6 October 2011, four ice cores were extracted at 3,860 metres from the “Vedretta Alta dell’Ortles” glacier in South Tyrol. This is the first time ice cores have been extracted from the Eastern Alps. The rock, which lies 75 metres below the glacier, was reached during three of the extractions, whereas during the last operation, perforation only reached 60 metres.

13th October 3-1. Let’s summarise!

Today we would like to summarise what’s happened so far.

As you might have guessed, the group of researchers has left the summit glacier of the Ortler mountain where perforation activities had been taking place. They took down all structures beginning the afternoon of 6 October and left the site the following morning. The helicopter had to make 20 return flights in order to bring all the material down to the valley, including the four precious ice cores which had been extracted during four separate operations.

4 October 2011 – …and a THIRD!

Yesterday the researchers and technicians were able to extract another ice core from the summit glacier of the Ortler mountain. For the third time within just a few days they were able to reach the rocks on which the glacier lies.

This time, not only the climatic but also the perforation conditions were particularly favourable. Since the upper layers only contained little melt water, which therefore did not obstruct the hole, the perforation was faster.
