Detecting Mesopelagic Organisms Using Biogeochemical‐Argo Floats [PDF]
Geophysical Research Letters, 2020 AbstractDuring the North Atlantic Aerosols and Marine Ecosystems Study in the western North Atlantic, float‐based profiles of fluorescent dissolved organic matter and backscattering exhibited distinct spike layers at 300 m. The locations of the spikes were at depths similar or shallower to where a ship‐based scientific echo sounder identified layers ...

Assessing mesopelagic fish diversity and diel vertical migration with environmental DNA
Frontiers in Marine Science, 2023 Mesopelagic fishes are an important component of the world’s oceans in terms of their abundance, biomass, and ecosystem function. These fishes are important contributors to the biological carbon pump via their feeding and behaviors, whereby they ...

Science governs the future of the mesopelagic zone
npj Ocean Sustainability, 2023 The potential of the mesopelagic zone (200–1000 m depth) to provide natural resources and ecosystem services is of increasing interest to a broad range of societal stakeholders. As this interest grows, divergent ideas about its current and future role in

Social behaviour in mesopelagic jellyfish [PDF]
Scientific Reports, 2015 AbstractGelatinous organisms apparently play a central role in deep pelagic ecosystems, but lack of observational methodologies has restricted information on their behaviour. We made acoustic records of diel migrating jellyfish Periphylla periphylla forming small, ephemeral groups at the upper fringe of an acoustic scattering layer consisting of krill.

Alcanivorax bacteria as important polypropylene degraders in mesopelagic environments
Applied and Environmental Microbiology, 2023 Plastics are causing serious problems in the sea and settling even to abyssal depths. Polypropylene (PP) is the second most common plastic product and thus would constitute a large fraction of plastics in the sea.

Frontiers in Marine Science, 2023 Introduction Mesopelagic fishes play a central role in the transfer of energy through open-ocean food webs, particularly in the Southern Ocean where they are both important predators of zooplankton and a key prey group for many higher predators. However,

Effects of migrating mesopelagic fishes on the biological carbon pump
Marine Ecology Progress Series, 2023 : Mesopelagic fishes and invertebrates contribute to the biological carbon pump (BCP) through direct and indirect effects on the gravitational, diffusive, and migrant (active) fluxes. Here, we analyzed the effect of these organisms on total carbon export

Frontiers in Marine Science, 2021 The Clarion-Clipperton Zone (CCZ) is a 4 million km2 area in the eastern Central Pacific Ocean exhibiting large variability in environmental parameters, particularly oxygen and primary production, that is being targeted for deep-sea polymetallic nodule ...

Scientific Reports, 2023 Mesopelagic fish constitute the most abundant vertebrate group in the marine environment. The current work reports on results of three seasonal acoustic cruises carried out in the Gulf of Corinth, a relatively small, deep, isolated basin located in the ...
