Diatoms and biofilm attached to the surface of microplastic debris observed by scanning electron microscopy. This plastic was collected during the May 2014 7th Continent expedition to the North Atlantic ocean gyre, where a vast mass of floating plastic waste has accumulated. Several diatoms are visible covered by a biofilm. The biofilm here is a bacterial community which has developed on plastic debris floating in the sea; this debris has been called the plastisphere.
