Infrastructure available for researchers

TZS offers a range of boats, laboratory equipment and analysers, and eqipment for field sampling. 

To use aquaria spaces, temperature-controlled rooms, particle size analyser, freeze dryer or microscopes, please contact research coordinator Laura Kauppi for booking. She will also quickly guide you to their use.

To use the laboratories and lab equipment, please contact head of laboratory Jaana Koistinen.

To book field equipment, please contact the TZS research technicians or Laura Kauppi. 

Larger research vessels r/v Augusta, J.A. Palmén and the hover craft r/v Saga are always booked through Göran Lundberg (senior technician, fleet manager) or Jostein Solbakken (research technician). Smaller motorboats are booked through the online booking system once you have a valid boat permit. Rowing boats can be booked through the online booking system or through the TZS office.

R/V AUGUSTA: R/V Augusta is a 18.5 m long catamaran, built in 2019 by Kewatec AluBoat (Kokkola, Finland) with a cruising speed of 18 knots. The vessel has a wet laboratory with fume hood cabinet, a climate chamber for sample incubation and a fridge and freezer for sample storage. The vessel has a dry lab with a large screen for presentations and own Wi-Fi net and monitor systems for basic environmental data. The vessel carries standard sampling equipment such as water samplers, plankton nets, sediment corers and grabs, dredges and trawls, and handheld probes (CTD, oxygen). It has capability for small-scale moorings and deployments up to 1000 kg: Fassi-type crane on aft deck with capacity of 1000 kg with 60m wire and 500 kg with 200m wire. Fassi-type crane on fore deck with capacity of 300 kg and 150 m wire. Capstan and rope lock for buoy anchor handling and also a smaller boom for handheld samplers. The crew consists of a captain and a chief engineer.

J.A. Palmén (Kulkuri 34): J.A. Palmén (JAP) is a 10.3 m long vessel with large open deck area for working, warm cabin and a toilet onboard. The large deck makes sampling from the boat easy and convenient. JAP can carry up to 12 passengers and it has a march speed of 17.5 knots. 

R/V SAGA: R/V Saga is an air-cushion vehicle (hover craft) for transports on ice and water. Big doors and walk-around deck make Saga suitable for sampling also in open-water conditions. Saga is equipped with a warn-winch in the bow and also an arm for water sampling as well as a ladder for divers. Saga can take up to 7 passengers or 700 kg payload in area 3. Saga’s speed and range are very dependent on wind and ice conditions; this needs to be discussed when planning a trip. 

9 - PALJU (Pioner Multi 5.3): Palju can carry up to 7 passengers in area 1 and 5 passengers in area 2 and it is especially good for diving. It has a flat bottom and large open area for working. In the front of the boat is a hatch that can be lowered down on the sea level for easy access in to the water and back.

8 - LOTA (Terhi 600): Lota has an inboard diesel motor and even if it is a slightly slower boat it has a proper ladder for divers and it can carry up to 10 passengers (or 6 divers). It is e.g. suitable for larger groups when working on the islands nearby the station or for courses.

7 - SAAVI (Pioner Multi 5.3): Saavi can carry up to 7 passengers in area 1 and 5 passengers in area 2 and it is especially good for diving. It has a flat bottom and large open area for working. In the front of the boat is a hatch that can be lowered down on the sea level for easy access in to the water and back.

5 - LINDER 445 Max: New boat for summer season 2022. Can carry up to four persons in areas 1 and 2 or two divers and one passenger.  

2 & 3 & 4 - LINDER (Linder 400 Sportsman): Linder 2 has 15 hp engine and Linder 3 & 4 have 9.9 hp engines and they are good when sampling in the local area around TZS. Linders carry up to 4 passengers (2 divers).

1 - MINIBUSTER: In use as a rowing boat, has no engine. When using the Mini Buster you should stay within rowing distance from the station.

ROWING BOATS 1-4: These four rowing boats and boat number 1 Minibuster can be used free of charge by those visiting TZS, but they also need to be booked in advance via the online booking system.

  1. A personal permit is needed for driving motorboats.

  2. The captain of the boat is responsible for the boat and the safety of everyone on the boat. All people onboard have to follow the instructions of the captain.

  3. For safety reasons, the number of people on a boat shall not exceed the limit. The maximum number of persons allowed on each boat can be found in the boat booking system. Lota can carry 8 persons. Maximum number of people on J.A. Palmén is 12. NB! Other cargo (including dive gear) will reduce the maximum number of persons in the ratio of 70 kg = one person.

  4. All people on a boat with an outboard engine have to wear a life jacket at all times.

  5. It is absolutely prohibited to drive a boat under the influence of alcohol or to consume alcohol onboard.

  6. Before each trip, the destination and estimated time of return has to be stated in the online booking system.

  7. The captain of the boat has to clean the boat and remove all sampling gear after every trip.

  8. No equipment that belongs to the boat (e.g. anchor, bailer or tools) should be borrowed or removed from the boat.

  9. Malfunctions of motor and groundings etc. have to be reported immediately to Göran Lundberg. Do-it-yourself repairs are absolutely forbidden. The permit will be cancelled immediately if one has not reported a boating accident.

  10. Maximum allowed speed in the vicinity of the station is 9 km/h (5 knots).

Seven temperature-controlled rooms in the main building, 1st floor. One of them is usable in sub-zero temperature.

Three temperature-regulated aquaria rooms. Two in the main building, ground floor, and one in the main building, 1st floor. Downstairs aquaria rooms are predominantly meant for large indoor mesocosm experiments and there is a possibility to use heated or cooled seawater. The upstairs aquarium room is suitable for smaller scale experiments.

Outside aquaria facilities (greenhouses). Flow-through seawater, electricity, no temperature control. Light following the in-situ light conditions.

Outdoor mesocosm facility consisting of twelve mesocosm bags. 

Wet lab on the ground floor of the main building and sieving station in front of the boat shed and onboard r/v Augusta ship schedule permitting.

Excellent possibilities for field experiments in a variety of different coastal habitats. Contact the TZS research coordinators for more information.

TZS has some diving and snorkeling equipment located in the boat house, contact dive safety officers Edd Stockdale or Hanna Halonen if you plan to do diving at TZS. Only diving for research purposes is allowed. There is a compressor for filling tanks (200 and 300 bar) for a fee paid per tank.

Several rooms with dry lab space for analysis and sample preparation and handling. Please consult head of laboratory Jaana Koistinen for booking and more information.
