It was a beautiful Swedish sunny Saturday the 9th of August when the crew for leg 3 of this Baltic Sea Expedition gathered in the harbour of Sandhamn in the archipelago of Stockholm. We were all excited when approaching this magnificent sailing boat, the Sea Dragon, that was about to be our home for the next seven days. The aim of this trip is to set sail for the northern parts of the Gulf of Bottnia in the Baltic Sea and take samples of the water along the way.
