COMPOSITION AND STRUCTURE OF NECTONIC ASSOCIATION IN MESOPELAGIC ZONE OF SEA OF OKHOTSK [PDF]

, 1996
The species composition of the fishs and calamaries in the mesopelagic zone of Sea of Okhotsk has been made accurate. The characteristic signs on the quantitative composition of the mesopelagic zone necton have been studied firstly, the connection of the

Methane and microbial dynamics in the Gulf of Mexico water column

Frontiers in Marine Science, 2015
In contrast to other oligotrophic water bodies the Gulf of Mexico (GOM) hosts an abundance of hydrocarbon seeps, which likely influences the microbial assemblages it hosts particularly regarding the availability of labile carbon in the aphotic GOM.

Archaeal Tetraether Lipids as Tracers for Past Marine Environmental Change

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract Archaea are single‐celled microorganisms that are abundant in marine environments and play a key role in the carbon and nitrogen cycles. Archaea can biosynthesize a wide variety of isoprenoid membrane lipids, including isoprenoid glycerol dibiphytanyl glycerol tetraethers (isoGDGTs).

Population ecology of mesopelagic fishes [PDF]

, 2022
This thesis focuses mainly on mesopelagic fishes, and mesopelagic fish species Maurolicus muelleri. Mesopelagic fishes are found in the oceanic twilight zone starting at the end of the euphotic zone down to approximately 1000 meters. The mesopelagic zone

Giant aggregates: Importance as microbial centers and agents of material flux in the mesopelagic zone [PDF]

Limnology and Oceanography, 1998
By using a remotely operated vehicle (ROV), we studied large mucous aggregates produced by the larvacean Bathochordaeus in Monterey Bay, California. These fragile structures or “houses,” cannot be sampled by typical water or net collecting devices, and likely represent a class of cosmopolitan, widely spaced aggregates in subsurface waters.

Coarse-scale vertical distribution of pelagic amphipods in two contrasting seasons of the southern Gulf of Mexico

Frontiers in Marine Science
In the oceans, ecological analyses of pelagic amphipods have mainly focused on the epipelagic zone with few studies in the deep waters. In this study, a coarse-scale vertical analysis, between 0 and 1000 m depth, was performed in the southern Gulf of ...

Advancing Ecological Understanding and Sustainable Management of Small Pelagic Fish

Fish and Fisheries, Volume 27, Issue 4, Page 850-864, July 2026.
ABSTRACT Small pelagic fish (SPF) are critical to the trophodynamic structure and function of marine systems and support some of the most valuable and socially important fisheries worldwide. Their “boom and bust” population dynamics, shifts in distribution, and importance as forage resources for other fish stocks place unique challenges to assessing ...

Deep Dark Futures: Foresighting Human Impacts on Mesopelagic Ecosystem Services

Fish and Fisheries, Volume 27, Issue 4, Page 876-894, July 2026.
This study uses foresighting to explore four plausible future scenarios of human activity affecting mesopelagic ecosystem services; provisioning, regulating, supporting and cultural. Using participatory scenario development, qualitative network modelling and indicator design, we assess systemic risks and early warning signals linked to harvest, climate

Gradients of bacteria in the oceanic water column reveal finely-resolved vertical distributions.

PLoS ONE
Bacterial communities directly influence ecological processes in the ocean, and depth has a major influence due to the changeover in primary energy sources between the sunlit photic zone and dark ocean.

Using 228Th/228Ra Disequilibrium to Constrain Particulate Organic Carbon Export From the Upper Twilight Zone of the Northern South China Sea

Geochemistry, Geophysics, Geosystems, 2023
We utilized the 228Th/228Ra and 234Th/238U disequilibrium methods to estimate the export of particulate organic carbon (POC) from the upper twilight zone in the northern South China Sea during four cruises from August 2009 to May 2011, covering an entire
