Copepod faecal pellet transfer through the meso- and bathypelagic layers in the Southern Ocean in spring [PDF]
Biogeosciences, 2017 The faecal pellets (FPs) 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.

Unlocking the Depths: Use of a Trait‐Based Approach to Reveal the Diversity of Foraging Strategies in a Deep‐Pelagic Fish Community [PDF]
Ecology and EvolutionCommunity trait structure is shaped by environmental filtering and limiting similarity, balancing abiotic selection and competitive divergence. In the context of environmental change and anthropogenic pressures, increasing our understanding of the ...

Unveiling ongoing biogeochemical dynamics of CDOM from surface to deep ocean [PDF]
Nature CommunicationsUnderstanding the dynamics of marine dissolved organic carbon (DOC) is essential for predicting its role in carbon cycling and its response to climate change. Here, we unveil molecular transformations of marine chromophoric dissolved organic matter (CDOM)

The Meso- and Bathypelagic Archaeal and Bacterial Communities of the Southern Gulf of Mexico Are Dominated by Nitrifiers and Hydrocarbon Degraders [PDF]
MicroorganismsThe Gulf of Mexico (GoM) is a complex oceanic basin with a maximum depth of 4000 m. It is a complex hydrodynamic system formed by different water masses with distinctive physical and biological characteristics that shape its rich biodiversity.

Major contribution of prokaryotes to carbon fluxes in the pelagic microbial food webs of the Mediterranean Sea [PDF]
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.

Depth shapes microbiome assembly and network stability in the Mariana Trench [PDF]
Microbiology SpectrumThe Mariana Trench, a stable marine ecosystem minimally impacted by human activities, has the greatest vertical depth in the ocean. Depth gradients profoundly influence the physical, chemical, and biotic conditions in the deep oceans.

Gradients of bacteria in the oceanic water column reveal finely-resolved vertical distributions. [PDF]
PLoS ONEBacterial communities directly influence ecological processes in the ocean, and depth has a major influence due to the changeover in primary energy sources between the sunlit photic zone and dark ocean.
