Labs and lab equipment Tjärnö


The Yellow Lab to the left and The Ecotron with Seaweed house to the right.

The Ecotron
Deck with space for 3 troughs (5.7 metres long, 1.2 metres wide and 0.5 metre deep) and 10 troughs (1.0 metre long, 1.0 metre wide and 1.0 metre deep), equipped with flow-through deep and surface water (called mesocosms). Trough water depth is adjustable. With organisms in the troughs, experiments can be conducted in seminatural conditions. The advantage of The Ecotron is that you can manipulate external factors in a relatively ecologically realistic environment compared to laboratory conditions.

The adjacent Yellow Lab has deep and surface water, 8 lab benches 2 m2 each. A microscopy room contains an inverted microscope (Olympus IX 71), a stereomicroscope (Olympus SZX 12) and a camera that suits both. Fridge and freezer. The purpose with Yellow Lab is working without hazardous chemicals.

Seaweed house, floor area 60 m2
Used for macroalgae aquaculture research, for development of blue biotechnology. Approx. 30 cultivations tanks, of 400 litre and 100 litre volume. Deep and surface water, of which one of them can be temperature regulated. Incoming water is filtered to 5 µm and treated with UV light. Air temperature regulation by automatic ventilation and heat pumps. Timer-regulated growth lamps and automated shade cloths. At the moment the Seaweed house is fully used by the Tjärnö aquaculture research group. The Seaweed house is available upon agreement with Göran Nylund or Gunilla Toth.


The Seaweed house with approx. 30 tanks, for macroalgae aquaculture research.

To the Tjärnö aquaculture research group there is also the working raft Algot 1 (see film to the right). It is 8 metres long, 4 metres wide, has a generator which gives 360/220 V AC and a crane which lifts 500 kg, 2 metres from raft. Algot 1 is available upon agreement with Gunnar Cervin.

The Baltotron
Mesocosm aquarium system for the study of i.e. species from the Baltic. 6 troughs with sea water systems independent of each other. Each trough is divided in two, each half with a volume of approx. 860 litres. The Baltotron can be used with either recirculation or through-flow, with control of salinity and temperature. It is also possible to split the flow in order to increase replication. Underneath the troughs there is a drainage system, connected to either the sea or municipal sewage plant, depending on species studied. The Baltotron is approved by Swedish Board of Agriculture for work with fish, and can also be used for the study of alien species or populations.


The Baltotron consists of 6 troughs with sea water systems independent of each other.

FLUM/Hydrodynamic laboratory
Described equipment belongs to marine chemical ecology and biohydrodynamic group at the Department of Marine Sciences. Responsible for equipment are Ann Larsson and Per Jonsson and the equipment is available upon agreement with lab supervisors.

Larger flume tank with associated instruments: The flume tank is 6.5 metres long, 0.5 metre wide and 0.3 metre deep. The water (1200 litres) is recirculated through a pipe underneath the tank. The flow velocity can be regulated up to approx. 1 metre/sec and the velocity can be measured with a ADV (Acoustic Doppler Velocimeter, Nortek AS) in three dimensions at max 25 Hz. The walls of the flow tank are transparent and the water in the flume tank can be cooled to desired temperature. A laser based PIV/LIF system (LaVision with DaVis software) is installed by the flume tank. The PIV (Particle Image Velocimetry) system is measuring magnitude and direction of the flow in a two-dimensional plan with high spatial and temporal (max 15 Hz) resolution. With the LIF (Laser Induced Fluorescence) system, transport and dispersion of chemical substances in the water can be studied and spatial distribution of the substance in one dimension can be measured at max 15 Hz.

Smaller flume tank: The flume tank is 2 metres long, 0.2 metre wide and 0.1 metre deep. The tank with recirculating water holds 65 litres. Maximum flow velocity is 0.2 metre/sec.

Flow channel with flowthrough water: The flume tank is 1.7 metres long, 0.3 metre wide and 0.15 metre deep. The water is continuously flowing through the channel and the outflow is tapered and has adjustable width. Maximum flow velocity is approx. 0.05 metre/sec.

ADCP for water current measurements in the field: ADCP (Acoustic Doppler Current Profiler, 1 MHz Nortek AS) measures water current velocity in three dimensions and at multiple levels in the water column. The extent of the measuring layers can be varied 0.3-4 metres and the maximum registered speed is 10 metres/sec. The range of the profiler is approximately 10-20 metres depending on the properties of water. Assembly equipment is available for measurement from bottom upwards or towards the bottom.
