are widespread in the marine environment, however their physical behaviour and interaction with other biological and non-biological suspended particles are largely unknown.
examination of this interaction and its effect on the dispersal and deposition of the particles will be a major step forward in our understanding of the spreading of micro-plastics in the marine environment. Micro-plastics are typically positively or neutrally buoyant and the working hypothesis of this VILLUM Experiment is that the sedimentation depends strongly on the aggregation into larger aggregates composed of various combinations of sediments, plastics, algae, bacteria and maybe other substances too.
will be examined using a recently developed particle camera. We hope to be able to verify the results of our experiments by tracing the historical deposition of micro-plastics in Danish waters in sediment cores.
