Tjärnö Marinbiologiska Laboratorium - Sven Lovén Centre for Marine Sciences (TMBL)


The Sven Lovén Centre for Marine Sciences (SLC) is the largest Swedish marine research infrastructure unit, and is financed by UGOT. Including “resident scientists”, a total of ca.150 people work year-round at SLC. SLC runs Sweden's ASSEMBLE partnership, and its two marine stations offer ASSEMBLE Plus access services: Kristeneberg and Tjärnö (TMBL).

The research station at Tjärnö is situated at the Koster fjord which in 2009 was the first Swedish Marine National Park. The marine surroundings cover easy-to-reach low-impacted marine environments of a wide range of shallow and deep habitats, including deep cold-water coral reefs, all of which lie within 5-20 minutes from the research station. The great potential for field sampling and outdoor experimental manipulations, combined with indoor facilities for maintenance, culture, experiment and analysis, make this station an excellent resource for coastal marine research.


  • Cold-water coral reefs
  • Eelgrass meadows

Ecosystem access

  • R/V Nereus: 15-m vessel with access to all research equipment and ROV


Biological resources

  • Marine models: the unique and high level of organismal diversity available at the Lovén Centre includes many current and emerging marine model organisms, for example Ciona intestinalis, Balanus improvisus, Skeletonema marinoi and Myxine glutinosa 
  • A list of marine organisms found in the North East Atlantic can be found here

Experimental facilities and technology platforms

Laboratories and climate-controlled rooms with access to all basic research equipment.

Marine chemical Ecology Laboratory. Provides standard and state-of- the-art laboratory equipment for extraction, isolation, identification and quantification of natural products. Several cultured and wild organisms are also available, e.g. for bioassay-guided-fractionation of extracted metabolites. Special instrumentation includes:

  • Liquid Chromatography-Mass Spectrometer (Q-TOF, Agilent 6540) New 2012
  • Gas Chromatography-Mass Spectrometer (Electron Impact and Chemical Ionization)
  • Analytical and preparative High Performance Liquid Chromatography-systems with UV-, fluorescens- and refractive index- detectors
  • Marine Molecular Biology and Genetics Laboratories. Provides all the necessary equipment for population genetic and phylogenetic studies, including DNA/RNA extraction and quantification equipment, PCR and sequencing equipment and imaging systems for electrophoresis.
  • Biohydrodynamic Laboratory. Provides two flume tanks. Can be operated with seawater and be partially temperature controlled (15-20° C).
    • 7 m recirculating flume tank (flow speed: 0.001-0.5 m/s)
    • 1.5 m recirculating flume tank (for small-scale flows; 0.001-0.15 m/s)
  • Three types of equipment for flow measurements and flow visualisation
    • Acoustic Doppler Velocimeter (Nortek) for laboratory use. This ADV measures the 3-dimensional flow velocity in a 6x6x6 mm volume of water with a sampling frequency of 25 Hz.
    • Particle Image Velocimetry (LaVision) for laboratory use. This advanced PIV-system measures the 2-dimensional flow field with up to 15 Hz. The PIV-system also includes a module for Planar-Laser-Induced-Fluorescence (PLIF) used to visualize and measure the flow of dissolved markers.
    • Acoustic Doppler Current Profiler (Nortek). This ADCP is used for field work and is typically operated in a bottom-deployed mode where the 3-dimensional velcoity is measured in up to 30 vertical layers with a sampling frequency up to 2 Hz.
  • Special Motion Behaviour Analysis Laboratory
