Benthic Flux
Flux is defined as the rate that fluid, chemicals, particles, or energy flows through a surface, and benthic refers to the bottom of an ocean, estuary, or lake. Therefore, benthic flux is the rate that chemicals dissolved in water flow out of or into the bottom of aquatic systems. More specifically, benthic flux (sometimes referred to as internal recycling) represents the transport of dissolved chemical species across the solid-liquid interface at the bottom of aquatic systems. The flux of solutes can be either positive (into the water column from the sediment) or negative (out of the water column into the sediment) and can vary over multiple temporal and spatial scales.
