Report of Working Group II: Particles
The nature and fluxes of particles occurring in the open ocean surface layer are depicted schematically in Fig. 1. The net flux of particles from the atmosphere to the surface ocean is comprised of both an external input of continental aerosols and a recycled component of ocean derived aerosols. These atmospheric aerosols can be transported to the surface layer either as wet or dry fallout and enter the surface waters through the photochemically active surface microlayer. During these transfer steps the aerosols can be substantially modified and may enter the surface water in a form ranging from totally dissolved to totally particulate.
