On 29 January 1833, Charles Darwin sailed on the HMS Beagle through the strait now known as the Beagle channel. Sailing on this ship, Darwin came to his first ideas on evolution – for which he became famous. Nowadays this very channel forms the border between Argentina and Chile. We decided on our day off to retrace his ‘steps’ by taking a sailing trip in the Beagle Channel.

One major goal in the WISE campaign is to follow the time evolution of air masses in the UTLS (upper troposphere-lower stratosphere) and to see how they are affected by tropopheric-stratospheric exchange. The latest (and upcoming) research flights are planned to provide an idea of exacty this time evolution. Flight 10 last Saturday was targeting a feature in the West-Atlantic with the plan to probe the same air again in later flights. At the moment, HALO is on its way to catch it now, two days later close to the Norwegian border.
