Metagenome-assembled genomes from particle-associated microbial communities in the mesopelagic zone of the Pacific Ocean. [PDF]

Microbiol Resour Announc, 2023
We report 10 particle-associated metagenome-assembled genomes (MAGs) from the mesopelagic zone of Pacific Ocean seawaters. MAGs comprise members of Flavobacteria Halomonas , Blastomonas , Brevundimonas , Alteromonas, Shingomonas , Sphingopyxis ...

Nitrospina-Like Bacteria Are Potential Mercury Methylators in the Mesopelagic Zone in the East China Sea. [PDF]

Front Microbiol, 2020
In natural environments, the production of neurotoxic and bioaccumulative methylmercury (MeHg) is mediated by microorganisms carrying the genes hgcA and hgcB. However, the contribution of these microorganisms to mercury (Hg) methylation or MeHg accumulation in the ocean is poorly understood. Here we determined the total Hg (THg) and MeHg concentrations

Summer distribution of squids in the mesopelagic zone of the Sea of Okhotsk [PDF]

, 1991
A large-scale trawl survey in August 1989 and data from other surveys indicate that the mesopelagic zone (depth 200-500m) of the Sea of Okhotsk is most densely populated with squids, wit maximum catches of more than 500kg/h.

Slow-sinking particulate organic carbon and its attenuation in the mesopelagic water of the South China Sea

Frontiers in Marine Science, 2022
Coastal acidification has been widely investigated in terms of its rationale and ecological effects in the last decade. However, the driving mechanism for acidification in open seawater, especially in mesopelagic water, is still poorly understood.

Carbon flow and food web structure in the mesopelagic zone of the North Atlantic Ocean [PDF]

Mesopelagic ecosystems are vital habitats that link the euphotic zone and the deep ocean through food web interactions and carbon flow pathways. In this dissertation, I use carbon compound-specific stable carbon isotope analysis of amino acids (CSIA-AA ...

Otolith characterization and integrative species identification of adult mesopelagic fishes from the western North Atlantic Ocean

Frontiers in Marine Science, 2023
Fish diversity and ecology in the ocean’s mesopelagic zone are understudied compared to other marine regions despite growing interest in harvesting these potential resources.

A RUpture‐Based detection method for the Active mesopeLagIc Zone (RUBALIZ): A crucial step toward rigorous carbon budget assessments [PDF]

, 2022
International audienceDetermining mesopelagic organic carbon budgets is essential to characterize the ocean's role as a carbon dioxide sink. This is because the biological processes observed in the mesopelagic zone are crucial for understanding the ...

Increased ocean carbon export in the Sargasso Sea linked to climate variability is countered by its enhanced mesopelagic attenuation [PDF]

Biogeosciences, 2010
Photosynthetic CO2 uptake by oceanic phytoplankton and subsequent export of particulate organic carbon (POC) to the ocean interior comprises a globally significant biological carbon pump, controlled in part by the composition of the planktonic community.

Vertical Migration of Pelagic and Mesopelagic Scatterers From ADCP Backscatter Data in the Southern Norwegian Sea

Frontiers in Marine Science, 2021
Records of backscatter and vertical velocity obtained from moored Acoustic Doppler Current Profilers (ADCP) enabled new insights into the dynamics of deep scattering layers (DSLs) and diel vertical migration (DVM) of mesopelagic biomass between these ...

Nitrogen supply in the upwelling of mid-west region of the South China Sea: The case of mesopelagic fishes

Ecological Indicators, 2023
Coastal upwelling zone hosts most fishing grounds worldwide and nitrogen dynamics in those systems mainly have been addressed through the nutrients replenished the ecosystem.
