This article presents a review of the sources of dissolved silicate to the marine environment and the associated sinks (i.e., burial sites) of particulate silica (SiO2) in the oceans. The dominant sources of dissolved silicate to the oceans are from rivers, groundwater, rainfall, and hydrothermal vent flux, whereas the dominant removal mechanisms for silica are the burial of marine diatoms in nearshore, continental margin, and deep-sea sediments. Burial of silica as sponge spicules and authigenic clay minerals certainly occurs, but they are expected to make a small contribution to the overall marine silica budget.
