Ships

At the Tjärnö Laboratory there is the 16 metre-long research vessel Nereus. In addition there is the 8.5 metre ship Doris as well as six small boats with outboard engines.

R/V Nereus

The research vessel Nereus, length 16 metres, is equipped for marine education and research during day-trips in coastal waters. The trained and experienced crew is familiar with handling and deploying scientific equipment, and with local conditions. During inshore expeditions Nereus can take 48 persons on board, during offshore expeditions 23 persons.

Nereus is equipped with AIS (Automatic Identification System). The ship sends regularly information about its position, course, speed, etc. You can follow the track of Nereus on MarineTraffic.

The ships have a wide selection of instruments and sampling equipment both for open water and sediment, including plankton nets, dredges, CTD, rosette water sampler, remotely operated vehicles (ROV) etc.

We also have field equipment used in shallow waters and from land, as well as from smaller boats.

Smaller boats

At Tjärnö Laboratory there are six smaller boats with outboard engines.
