Diel vertical distribution of copepods during spring in the Northeast Atlantic Ocean

open access: yesFrontiers in Marine Science
Vertical migration is a rather complex behavior by which multiple species of different sizes move from the meso- and bathy-pelagic zones, where they reside during day to avoid predators, to the epipelagic zone for feeding.

Feeding of smoothtongue Leuroglossus schmidti in the Bering, Okhotsk Seas and adjacent waters of the Pacific Ocean

open access: yesИзвестия ТИНРО, 2016
Smoothtongue Leuroglossus schmidti is a small mesopelagic fish species common for subarctic waters. It rises to the upper epipelagic layer at night for feeding and preys mainly on euphausiids, copepods and amphipods.

Swimming Activity as an Indicator of Seasonal Diapause in the Copepod Calanus finmarchicus

open access: yesFrontiers in Marine Science, 2022
Copepods dominate zooplankton biomass of the upper ocean, especially in the highly seasonal boreal and polar regions, for which specific life-cycle traits such as the accumulation of lipid reserves, migration into deep water and diapause are key ...

The downward legacy of a phytoplankton bloom in the oligotrophic North Pacific Subtropical Gyre

open access: yesLimnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract Ocean particles are a heterogeneous collection, including living and dead cells, feces, mucus‐rich aggregates, and mineral shells and frustules. In the well‐lit upper ocean, phototrophic processes fuel production of particulate matter; however, only a relatively small percentage (< 10% per day) of this material (mostly detrital) escapes the ...

Microbial Respiration Across Subtropical Eddies: Submesoscale Variability and Biogeochemical Drivers

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Island‐induced eddies from the Canary Islands region propagate southwestward along the Canary Eddy Corridor, exporting biological and biogeochemical properties to the oligotrophic open ocean. However, their contribution to organic matter remineralization, and consequently to the biological carbon pump, throughout their life cycle remains ...

Picoplankton Diel Variability and Estimated Growth Rates in Epipelagic and Mesopelagic Waters of the Central Red Sea

open access: yesFrontiers in Marine Science, 2021
The diel variability of the abundance and cell size of picoplanktonic groups in the central Red Sea was monitored every 2 h in situ on 4 occasions (once per season) from 2015 to 2016.

Quantifying the Morphological Differences Between Fur Seals and Sea Lions

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The eared seals (family Otariidae) are divided into fur seals and sea lions, despite a lack of cladistic support for these groups. The division is primarily based on hair morphology, and it is unknown whether any other morphological signal differentiates these two groups.

Marine Functional Connectivity Contributes to Ecosystem Functioning Across Multiple Scales

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT The passive transport and active movements of marine organisms between habitats and ecosystems, known as marine functional connectivity, play a critical role in the functioning of marine ecosystems. However, marine functional connectivity, particularly at large spatial scales, is often understudied, and consequently tends to be overlooked in ...

Co-occurrence analysis of microbial taxa in the Atlantic Ocean reveals high connectivity in the free-living bacterioplankton

open access: yesFrontiers in Microbiology, 2016
We determined the taxonomic composition of the bacterioplankton of the epipelagic zone of the Atlantic Ocean along a latitudinal transect (51°S – 47°N) using Illumina sequencing of the V5-V6 region of the 16S rRNA gene and inferred co-occurrence networks.
