MARINE FACILITIES AND LABORATORIES


the lab

Research premises at TMBL are newly built and in very good condition. The main building includes laboratories for chemical, biohydrodynamic and molecular analyses, a general laboratory and microscope room. There are also indoor aquaria and experimental halls, climate rooms with possibilities to regulate light and temperature, and an outdoor experimental facility. There are rich facilities for sorting and storing live organisms in aquaria and tanks.


Seawater system

sea water

Seawater with a minimum of 32 ‰ salinity is available all over the laboratory. It is a flow through system with a maximum capacity of 25 dm3/s. The water temperature can be regulated between 0° and 30° C year round.

The seawater is also used for heating the buildings in winter and cooling them in summer. This is done through heat pumps that utilize the temperature differences in seawater coming in to and leaving the buildings.

The chemical ecology laboratory can provide both standard and state-of-the-art laboratory equipment for extraction, isolation, identification and quantification of natural products. Also several cultured and wild organisms are available, e.g. for bioassay-guided-fractionation of extracted metabolites.

The laboratory for biohydro-dynamics provides two indoor flumes and advanced equipment for flow measurement.

Special instrumentation includes:

  • Two straight recirculating flumes driven by propellers (7.3 m and 1.75 m)
  • Acoustic Doppler Velocimetry (Nortek) for lab and field measurements
  • Particle Image Velocimetry (DVC) for lab measurements

Special equipment includes:

  • Free-flowing filtered deep (30 m) seawater
  • Free-flowing unfiltered surface seawater
  • 12 large (5.70 x 1.20 m) mesocosms with adjustable depth and room for separate aquaria

Optical instrumentation includes high-quality stereomicroscopes, inverted microscopes and epifluorescence. Microscopes can be fitted with analytical and documentation tools, e.g. state-of-the-art motion analysis, image analysis, PIV, and a diversity of digital still and video cameras, as well as computer facilities.
