Puh! Disappointed and completely exhausted, full of questions and hungry! I’m eating while writing this. I wish I could sleep simultaneously but if I do I will sleep for a week. We have worked 12h per day this week and made a lot of progress. Analysis of the data is extremely exciting and shows many unexpected results. Have transport times changed because of a change in the arctic conditions? These isotopes travel to Greenland through the North Atlantic and to some extent through the Arctic Ocean. I only have a small number of data but my colleagues seem to be very interested. We need to wait for some months to see the whole set of data.
