Changes in zooplankton communities from epipelagic to lower mesopelagic waters

open access: yesMarine Environmental Research, 2019
Zooplankton form a trophic link between primary producers and higher trophic levels, and exert significant influence on the vertical transport of carbon through the water column ('biological carbon pump'). Using a MultiNet we sampled and studied mesozooplankton communities (i.e.

Estimating how vertically migrating zooplankton impact epipelagic communities with mesocosm experiments

open access: yes
International audienceVertically migrating zooplankton play a key role in the carbon pump by transporting particulate and dissolved carbon from the epipelagic to the deep ocean. Monitoring to the deep ocean.

Cetaceans and sea turtles in the northern region of the Mediterranean Cetacean Migration Corridor: abundance and multi-model habitat suitability analysis

open access: yesFrontiers in Marine Science
The Mediterranean Cetacean Migration Corridor is one of the largest marine protected areas in the Mediterranean Sea. Nevertheless, little is known about the abundance and distribution of cetaceans and sea turtles in the area.

Seasonal Re‐Entrainment of Respired Organic Matter Decouples Southern Ocean Surface Production and Annual Net Community Production

open access: yesAGU Advances, Volume 7, Issue 5, August 2026.
Abstract The long‐term storage of carbon by the biological carbon pump depends on the amount of organic carbon produced in sunlit waters, the depth at which that organic carbon is respired, and the time until the respired carbon is again in contact with the atmosphere. In the Southern Ocean, estimates of organic carbon export, net community production (

Distribution of epipelagic biomass in Puget Sound over the summer

open access: yes, 2014
Fishes often utilize multiple habitats over the course of their estuarine residence. Puget Sound, WA, provides epipelagic habitat to a variety of species, including declining populations of (Pacific herring, Clupea pallasi) and Endangered Species Act ...

Epipelagic and mesopelagic fishes in the southern California Current System: Ecological interactions and oceanographic influences on their abundance [PDF]

open access: yes, 2014
We use zooplankton and ichthyoplankton data from the ~ 60-year CalCOFI time series to examine relationships of mesopelagic (. i.e. midwater) fishes in the California Current System with midwater predators, potential competitors (epipelagic planktivorous ...

Population Genetic Structure of the Tropical Two-Wing Flyingfish (Exocoetus volitans).

open access: yesPLoS ONE, 2016
Delineating populations of pantropical marine fish is a difficult process, due to widespread geographic ranges and complex life history traits in most species.

High‐Resolution Particle Imaging Reveals the Importance of Phytodetrital Aggregate Flux and Mesopelagic Grazing for Carbon Storage in the Southern Ocean

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 8, August 2026.
Abstract The biological, chemical, and physical processes in the mesopelagic zone that impact carbon flux to the deep ocean are poorly understood, particularly in the Southern Ocean, despite their importance to deep ocean carbon storage. Using a CTD‐mounted underwater imaging system, the Underwater Vision Profiler 5, we observed distributions of large ...

Copepod‐associated microbial biogeography in the epipelagic ocean

open access: yesLimnology and Oceanography Letters
Abstract Zooplankton‐microbial interactions play crucial roles in epipelagic ecosystem functions. The distinct west‐to‐east gradients and complex circulation patterns in the Mediterranean Sea, combined with the ubiquity of pelagic copepods, provide an ideal model to study the ecological processes driving host‐associated microbial ...

Vertical distribution of epipelagic siphonophores at the confluence between Benguela waters and the Angola Current over 48 hours

open access: yes, 2022
8 pages, 4 figures, 1 tableThe diel distribution of epipelagic siphonophores at a station off northern Namibia (18°00′ S 10°30′ E) was studied. This area is characterized by the mixing of surface waters of the Angola Current with the waters of the ...
