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

open access: yesDeep-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.

The influence of a Hawaiian seamount on mesopelagic micronekton

Deep-Sea Research Part I: Oceanographic Research Papers, 2009
Abstract The distribution of mesopelagic micronekton (small fishes, crustaceans, and cephalopods) is not uniform throughout the oceans. Seamounts are a feature that may influence the abundance, biomass, diversity, and taxonomic composition of a community of mesopelagic micronekton by introducing a hard substrate and benthic predators into a realm ...

Acoustic characterisation of micronekton distribution in French Polynesia [PDF]

open access: yesMarine Ecology - Progress Series, 1999
Tuna distribution may be directly linked to food availability, the density of which can be assessed by echo-sounding. A study was performed in the French Polynesian EEZ (Economic Exclusive Zone) between 1995 and 1997 with a 38 kHz echo sounder working down to 500 m depth.

Global characterization of modelled micronekton in biophysically defined provinces

open access: yesProgress 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 ...
