    Abstract : Resuspension of sediment by anthropogenic disturbances is a concern due to the impacts it has on organisms and ecosystems. Bottom trawling is one major cause of sediment resuspension. A field study showed that a small trawl created a sediment plume 120 - 150 m wide and 15-18 m high (Paper 1). The sediment in the same study was highly contaminated. READ MORE

  5. 5. Prevalence, extent and severity of peri-implantitis

    Author : Christer Fransson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
