Major contribution of prokaryotes to carbon fluxes in the pelagic microbial food webs of the Mediterranean Sea

Advances in Oceanography and Limnology, 2016
In this study, we carried out dilution experiments at the surface and in the mesopelagic and bathypelagic layers at 15 sites in the Mediterranean Sea that covered a wide range of trophic conditions.

Microbial Controls on Dissolved Organic Nitrogen Cycling During Long‐Term Degradation Experiments

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Dissolved organic nitrogen (DON) is critical for marine microbial growth by providing carbon and nitrogen. Although DON is rapidly cycled, some compounds within this pool can persist for long‐periods of time. To better understand how DON is cycled by marine microorganisms, we conducted 548‐day incubations using surface‐derived dissolved ...

Bacterioplankton distribution and production in the bathypelagic ocean: Directly coupled to particulate organic carbon export?, [PDF]

, 2003
A recently published evaluation of bacterioplankton abundance and productivity in the bathypelagic North Pacific suggests that these properties are generally coupled with particulate organic carbon (POC) fluxes.

Hiding in Plain Sight: Elopomorph Larvae Are Important Contributors to Fish Biodiversity in a Low-Latitude Oceanic Ecosystem

Frontiers in Marine Science, 2020
Leptocephalus larvae of elopomorph fishes are a cryptic component of fish diversity in nearshore and oceanic habitats. However, identifying those leptocephali can be important in illuminating species richness in a region.

The Deep‐Sea Preyscapes of Mammalian Top Predators

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Deep‐sea predator foraging is shaped by prey richness, accessibility, and density. Using eDNA and acoustics, we mapped fish and cephalopod communities across inshore‐offshore gradients around the Azores in foraging habitats of three co‐occurring deep‐diving toothed whales.

DNA stable‐isotope probing reveals potential key players for microbial decomposition and degradation of diatom‐derived marine particulate matter

MicrobiologyOpen, 2020
Microbially mediated decomposition of particulate organic carbon (POC) is a central component of the oceanic carbon cycle, controlling the flux of organic carbon from the surface ocean to the deep ocean.

The Bathypelagic Biome of the Atlantic Ocean: Character and Ecological Discreteness of the Fish Fauna [PDF]

, 2012
Recent global synthetic analyses have revealed that marine taxonomic inventories are far from complete, nowhere more so than in the deep-pelagic ocean. At over a billion km3, it is the largest biome on Earth, yet only a tiny fraction of the biogeographic

Abundance, biomass and respiration data of fishes (Stomiiformes) from the BATHYPELAGIC cruise (June 2018) in Northeast Atlantic Ocean

, 2022
The values of carbon remineralisation were measured in juveniles/adults of 5 non-migratory bristlemouth fishes (Cyclothone spp.) and partial migrator (Argyropelecus hemigymnus) sampled during the BATHYPELAGIC cruise (North Atlantic, June 2018).

Zooplankton faecal pellet transfer through the meso- and bathypelagic layers in the Southern Ocean in spring

, 2016
The faecal pellets (FP) of zooplankton can be important vehicles for the transfer of particulate organic carbon (POC) to the deep ocean, often making large contributions to carbon sequestration.

An inside look at bathypelagic viruses

, 2018
Extensive research in surface ocean layers has demonstrated that viruses are significant components of marine microbial communities. But the dark ocean is the largest and the most unexplored habitat in the biosphere, comprising 1.3 X 1018 m3 (Arístegui, 2009). Accordingly, evaluating the role of viruses in the deep ocean remains an elusive, but pivotal
