Biological composition and microbial dynamics of sinking particulate organic matter at abyssal depths in the oligotrophic open ocean [Ecology]

Sinking particles are a critical conduit for the export of organic material from surface waters to the deep ocean. Despite their importance in oceanic carbon cycling and export, little is known about the biotic composition, origins, and variability of sinking particles reaching abyssal depths. Here, we analyzed particle-associated nucleic acids...
