Mesoscale features and micronekton in the Mozambique Channel: An acoustic approach

Deep Sea Research Part II: Topical Studies in Oceanography, 2014
The oceanic circulation in the Mozambique Channel (MZC) is dominated by mesoscale cyclonic and anticyclonic eddies that are known to play a key role in biological processes of less-productive deep-sea ecosystems by converting physical energy into trophic energy and by restructuring and concentrating biomass across the eddy field.

Mesopelagic Particle Layers in the Dynamic Hypoxic Northern Benguela Are Shaped by Zooplankton Activity

Journal of Geophysical Research: Oceans, Volume 130, Issue 3, March 2025.
Abstract Hypoxic (O2 < 60 μmol kg−1) waters are found below 27% of the ocean surface and are predicted to expand in the near future; however, the organic carbon cycle in these regions is far from understood. Here we study the origin, composition, and temporal variability of mesopelagic particle layers in the hypoxic northern Benguela.

High Latitude Epipelagic and Mesopelagic Scattering Layers—A Reference for Future Arctic Ecosystem Change

Frontiers in Marine Science, 2017
Scattering structures, including deep (>200 m) scattering layers are common in most oceans, but have not previously been properly documented in the Arctic Ocean.

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

PLoS 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.

Characterizing the Central Structure of a Mesoscale Eddy‐Ring Dipole in the Mozambique Channel From In Situ Observations

Journal of Geophysical Research: Oceans, Volume 130, Issue 3, March 2025.
Abstract During the RESILIENCE cruise aboard the R/V Marion Dufresne II (April 19–24 May 2022), a high‐resolution in situ observation campaign investigated a mesoscale dipole in the Mozambique Channel, composed of a large anticyclonic ring and a cyclonic eddy.

Acoustics characterization of micronekton spatial distribution in Indian Ocean using scientific surveys and integrated marine observing system database: Acoustics characterization of micronekton

2015 IEEE/OES Acoustics in Underwater Geosciences Symposium (RIO Acoustics), 2015
In this work scientific echosounder were used hull mounted onboard R/V Marion Dufresne II to scrutinize the vertical distribution of micronekton according to water masses characteristics along transect which were discriminated with spatial remote sensing data.

Mesopelagic Fish Traits: Functions and Trade‐Offs

Fish and Fisheries, Volume 26, Issue 1, Page 83-103, January 2025.
ABSTRACT Fishes inhabiting the mesopelagic zone of the world's oceans are estimated to account for the majority of the world's fish biomass. They have recently attracted new attention because they are part of the biological carbon pump and have been reconsidered as a contribution to food security.

The deep scattering layer (DSL) of Indian EEZ [PDF]

, 2000
The deep scattering layer is a trophic network that carry numerous food chains, some of which end up in species of high economic value, such as oceanic squids, tunas, other scombroids, pelagic sharks etc.

Feeding habits of splendid alfonsino Beryx splendens in the vicinity of Kuroshio, the south of Japan

Fisheries Oceanography, Volume 34, Issue 1, January 2025.
Abstract Gut contents and nitrogen isotope ratio (δ15N) analyses were conducted on splendid alfonsino Beryx splendens collected in the vicinity of Kuroshio from May 2015 to November 2016 (n = 708) to identify their feeding habits in the Western North Pacific.

Global characterization of modelled micronekton in biophysically defined provinces

Progress in Oceanography
Micronekton are the mid-trophic level of the ecosystem and contribute to active carbon export to the deep ocean through diel vertical migrations. Better characterization of micronekton functional groups depending on relationships to environmental variables is useful for the management of marine resources, the conservation of biodiversity and a better ...
