Hello Mrs. Kaden!
I want to know how is the temperature at the arctic? And how thick is the ice at the mainland?
I hope you answer!
Greetings from Mrs. Töger and her class 10/2 from the Goethe-Grammer-School in Reichenbach.

Hi Julia,

The sea ice thickness varies with the location and the time of the year. When we started in August in Dutch Harbor there was no ice at all. The first ice we saw on August 9, 2005 at 74 N. It was not very thick and just floating around us. Now, the sea ice is about 1-3 m thick and at pressure ridges more than 12 m. The melt ponds start to freeze over. The Arctic is getting ready for winter. Our ship follows leads (small open water ways in the ice). However, sometimes we need to back and ram to go through the ice. Yesterday, we met with the ice breaker Oden from Sweden. We will go together through the heavy ice around the pole. We have researchers aboard that dial with the properties of ice, ice drift and composition. They drill into the ice to retrieve cores, record the grain sizes, optical properties and install buoys that give off signals to satellites. Researchers can figure out the polar ice drift and determine climate changes.

Best regards ,

Ute
