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.

Carbon injection potential of the mesopelagic-migrant pump in the Southern Ocean during summer

Frontiers in Marine Science
The passive sinking flux of particles, termed the biological gravitational pump (BGP), is an important component of the ocean’s biological carbon pump. In addition, carbon-rich particles are actively injected to depth through the diel vertical migration (

Distribution, population biology, and trophic ecology of the deepwater demersal fish Halosauropsis macrochir (Pisces: Halosauridae) on the mid-Atlantic Ridge.

PLoS ONE, 2012
Halosauropsis macrochir ranked amongst the most abundant and widespread demersal fishes on the mid-Atlantic Ridge of the North Atlantic (Iceland-Azores) with greatest abundance at 1700-3500 m.

Migrant biomass and respiratory carbon flux by zooplankton and micronekton in the subtropical northeast Atlantic Ocean (Canary Islands)

, 2015
Diel Vertical Migration (DVM) in marine ecosystems is performed by zooplankton and micronekton, promoting a poorly accounted export of carbon to the deep ocean.

Forage fauna in the diet of bigeye tuna (Thunnus obesus) in the western tropical Atlantic Ocean

Brazilian Journal of Oceanography, 2012
A total of 291 stomachs of bigeye tuna caught in the Western tropical Atlantic Ocean ranging between 60 and 195 cm fork length, were analyzed between October 2004 and November 2005.

Zooplankton abundance in subtropical waters: is there a lunar cycle?

Scientia Marina, 2001
Based on historical data of abundance, we report evidence of changes in zooplankton abundance in the 0-200 m layer related to the moon cycle confirming that this phenomenon is produced in the marine environment, similarly to the one described for ...

Proximate composition and overwintering strategies of Antarctic micronektonic Crustacea

Marine Ecology Progress Series, 1994
Proximate (protein, lipid, carbohydrate and chitin) and elemental (carbon and nitrogen) composition were determined for 18 species of Antarctic micronektonic Crustacea, representing the majority of species found in the Antarctic water column. Individuals used in the analyses were captured during fall and winter; for 8 species data were collected in ...

Trophic Structure and Food Web Dynamics of Deep-Pelagic Micronekton in the Gulf of Mexico [PDF]

, 2021
The deep-pelagic ocean is the largest but least studied ecosystem on Earth. As natural resource extraction and fisheries expand into the deep pelagic, there is increased need for comprehensive, ecosystem-based management plans for deep-pelagic ecosystems.

A novel approach to estimate active carbon flux using the micronekton biomass spectra

, 2017
Micronekton play a critical role in global carbon cycling, actively transporting carbon between the surface and deep ocean during diel migrations. Carbon transport is mediated through respiration, gut flux, excretion and mortality of migrating organisms.
