Tjärnö Marine Laboratory (TML)


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

  • Coastal research vessels (On-site service)
    • Small vessels (5–7 m), larger vessels (22 and 9 m)
  • Submersibles (On-site service)
    • ROVs depth rated from 500–2000 m, manipulator, sample storage, CTD, video- and still photography 


Biological resources

  • Marine model organisms (On-site service)
    • 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
    • A list of the species that can be maintained and spawned at the Lovén centre can be downloaded here 


Experimental facilities

  • Aquaria and tanks (On-site service)
    • Aquaria and tanks are available in sizes from 1 liter to 30 000 liters
  • Mesocosms (On-site service)​​​​​​​​​​​​​​
    • Deck with 12 troughs equipped with flow-through deep and surface water. Each trough is 5.7 metres long, 1.2 metres wide and 0.5 metre deep. Trough water depth is adjustable.
    • With organisms in the troughs, experiments can be conducted in seminatural conditions.
  • Climate controlled rooms (On-site service)​​​​​​​​​​​​​​
    • ​​​​​​​Six thermoregulated rooms where both air and water temperature can be regulated.
    • One of the rooms is suitable for work with non-native species; the drain is connected to the municipal sewage treatment plant.
    • A dry thermoregulated room located adjacent to other thermoregulated rooms, equipped with fume hood and a wet bench.
    • Three additional thermoregulated rooms with the ability to adjust room temperature and cool water. One is equipped with lighting fixtures for regulation of circadian rhythms.
  • Wet labs (On-site service)​​​​​​​​​​​​​​
    • ​​​​​​​Basic wet labs with lab benches, running seawater from surface and deep water
  • Dry labs (On-site service)​​​​​​​​​​​​​​
    • All labs have running deep and surface water, lab benches.
    • Labs are also equiped with fume hoods, fridges, freezers, microscopes, flumes.


Technology platforms

  • Molecular biology and omics (On-site service)​​​​​​​​​​​​​​
    • All the equipment necessary for population genetic and phylogenetic studies, including DNA/RNA extraction and quantification equipment, PCR and sequencing equipment and imaging systems for electrophoresis
  • Structural and chemical analysis (On-site service)​​​​​​​​​​​​​​
    • 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.


Supporting facilities

  • On-site lodging (On-site service)​​​​​​​​​​​​​​
  • On-site catering (On-site service)​​​​​​​​​​​​​​
