Trophic Diversity of Plankton in the Epipelagic and Mesopelagic Layers of the Tropical and Equatorial Atlantic Determined with Stable Isotopes

open access: yesDiversity, 2018
Plankton living in the deep ocean either migrate to the surface to feed or feed in situ on other organisms and detritus. Planktonic communities in the upper 800 m of the tropical and equatorial Atlantic were studied using the natural abundance of stable ...

Rich and underreported: First integrated assessment of the diversity of mesopelagic fishes in the Southwestern Tropical Atlantic

open access: yesFrontiers in Marine Science, 2022
Mesopelagic fishes play critical ecological roles by sequestering carbon, recycling nutrients, and acting as a key trophic link between primary consumers and higher trophic levels.

Prokaryotic respiration and production in the meso- and bathypelagic realm of the eastern and western North Atlantic basin [PDF]

open access: yes, 2006
We measured prokaryotic production and respiration in the major water masses of the North Atlantic down to a depth of,4,000 m by following the progression of the two branches of North Atlantic Deep Water (NADW) in the oceanic conveyor belt.

Controls over Ocean Mesopelagic Interior Carbon Storage (COMICS): fieldwork, synthesis and modelling efforts

open access: yesFrontiers in Marine Science, 2016
The ocean’s biological carbon pump plays a central role in regulating atmospheric CO2 levels. In particular, the depth at which sinking organic carbon is broken down and respired in the mesopelagic zone is critical, with deeper remineralisation resulting

Photon Hunting in the Twilight Zone: Visual Features of Mesopelagic Bioluminescent Sharks

open access: goldPLoS ONE, 2014
The mesopelagic zone is a visual scene continuum in which organisms have developed various strategies to optimize photon capture. Here, we used light microscopy, stereology-assisted retinal topographic mapping, spectrophotometry and microspectrophotometry to investigate the visual ecology of deep-sea bioluminescent sharks [four etmopterid species ...

Modeling the contribution of micronekton diel vertical migrations to carbon export in the mesopelagic zone [PDF]

open access: goldBiogeosciences
Abstract. Micronekton plays a significant but often overlooked role in carbon transport within the ocean. Using a one-dimensional trait-based model, we simulated the diel vertical migrations (DVMs) of micronekton and their carbon production through respiration, fecal pellets, excretion, and dead bodies.

Growth and natural mortality of Maurolicus muelleri and Benthosema glaciale in the Northeast Atlantic Ocean

open access: yesFrontiers in Marine Science, 2023
Mesopelagic fish are considered a possible future fisheries resource, but the biological sustainability of their potential exploitation has not yet been assessed.

The vertical distribution and biological transport of marine microplastics across the epipelagic and mesopelagic water column. [PDF]

open access: yes, 2019
Plastic waste has been documented in nearly all types of marine environments and has been found in species spanning all levels of marine food webs. Within these marine environments, deep pelagic waters encompass the largest ecosystems on Earth. We lack a

Body Size Regression Formulae, Proximate Composition and Energy Density of Eastern Bering Sea Mesopelagic Fish and Squid. [PDF]

open access: yesPLoS ONE, 2015
The ecological significance of fish and squid of the mesopelagic zone (200 m-1000 m) is evident by their pervasiveness in the diets of a broad spectrum of upper pelagic predators including other fishes and squids, seabirds and marine mammals.
