An OBS is recovered during heavy rain.

The OBS go back to Germany.

The pontoon is ready for work on Lake Lucerne.

After one year on the lake bottom, sediment has deposited on the OBS. 

For some people boating on the lake means holiday, for others it means recovering an OBS.

Much of the research does not take place in the field but in the office: this is the result of a simulation!

A new instrument has been recovered from the lake!

The OBS are ready for the next deployment!

Last check on deck before the next deployment!
