摘要: In the marine environment, settling particulates have been widely studied for their role as effective vertical transporters of nutrients and metals scavenged from the euphotic zone to the benthos. These particulates are composed of transparent exopolymers, plankton and bacterial cells, detritus and organic matter, and form various size fractions from colloids (< 0.2 μm) to aggregates, and finally marine snow (> 300 μm). As marine snow forms in the water column, anoxic layers form around and within the aggregation potentially creating a …
