The oceanic waters below a depth of 200 m represent, in terms of volume, the largest habitat
of the biosphere, harboring approximately 70% of the prokaryotic biomass in the oceanic …

Marine particles are key to the cycling of major elements on Earth and play an important role
in the balance of nutrients in the ocean. Three main categories of marine particles link the …

Sinking particulate organic carbon out of the surface ocean sequesters carbon on decadal to
millennial timescales. Predicting the particulate carbon flux is therefore critical for …

Marine dissolved organic matter (DOM) represents one of the largest reduced carbon pools
on Earth. Diverse microbial metabolic activities play important roles in shaping this pool …

Seagrasses are important primary producers in oceans worldwide. They live in shallow
coastal waters that are experiencing carbon dioxide enrichment and ocean acidification …

The production and consumption of organic matter by marine organisms plays a central role
in the marine carbon cycle. Labile organic compounds (metabolites) are the major currency …

In order to assess the impact of environmental conditions on marine zooplankton, we
conducted a survey around Novaya Zemlya (NZ), a large archipelago located within the …

As the major term in downward organic carbon flux attenuation, determining prokaryotic
metabolism over depth in the mesopelagic ocean is crucial for constraining the efficiency of …

Subtropical oceans contribute significantly to global primary production, but the fate of the
picophytoplankton that dominate in these low-nutrient regions is poorly understood. Working …

The metabolism of phytoplankton cells is synchronized with the diel light cycle. Likewise,
associated heterotrophic bacteria adjust their diel expression of transporter-and catabolism …
