Mismanaged plastic wastes accounting for 70% of marine debris remain persistently in the marine environment, even if they are being degraded and fragmentized to tiny microplastics. To date, it is far from answering how this anthropogenic, buoyant, and persistent matter which was first appeared in the earth history, contaminates (or is incorporated into) the earth system. The ocean plastic study requires the insight and methodology of a variety of earth sciences such as the oceanography, geology, and paleontology. We welcome studies on the plastic circulation from the land/atmosphere to upper oceans and bottom sediments, studies on microplastics as a proxy of the "Anthropocene", and studies to establish procedures in monitoring and analyzing macro/microplastics.
