From August 22 to September 21, 2013, the first expedition to the Laptev Sea within the framework of the project took place: TRANSDRIFT XXI. 22 participants (see photograph and list below) boarded RV Viktor Buynitskiy in Arkhangelsk on August 22 and sailed on August 25 along the Northern Sea Route toward the Laptev Sea.

During the very successful expedition, about 20 stations were carried out and four seafloor observatories were deployed in the Laptev Sea. They are equipped – among other devices – with state-of-the-art automatic water samplers. These will take one sample every week during one year. Thus, the physical changes of the water masses can be observed through all seasons. One seafloor observatory was recovered. It had been deployed in 2011 and took measurements for two whole years.

The daily expedition reports of TRANSDRIFT XXI are to be found here.
