The significance of macroscopic aggregates (marine snow) as sites for heterotrophic bacterial production in the mesopelagic zone of the subtropical Atlantic

Macroscopic detrital aggregates (known as marine snow) harbor greatly enriched populations of bacteria and protozoans, suggesting that they may be an important site of heterotrophic activity in the deep sea. We collected flocculent marine snow larger than 3 mm in diameter in the mesopelagic zone of the subtropical Atlantic from the submersible, Johnson-Sea-Link.
