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

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
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
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
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 ...

Quantifying the Morphological Differences Between Fur Seals and Sea Lions
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
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 ...

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.
