Marine Measurement Laboratory

The Marine Measurement Laboratory is where water, sediment and biological samples from field campaigns are processed. Three workflows are kept separate: nutrient and oxygen analysis, microplastic separation and polymer identification, and sensor calibration.

The microplastic line works under clean-room conditions. After density separation and organic matter removal, particles are counted under a stereo microscope and polymer type is identified by FTIR. Airborne contamination is the known weak point of this analysis; the laboratory runs a blank with every batch and reports the contamination level.

The sensor calibration corner lets CTD and oxygen probes due to go on a cruise be verified against reference solutions. Calibration records are published together with the datasets: how reliable a measurement is matters as much as the measurement itself.

The laboratory is also used for graduate teaching and provides analysis services to external institutions.
