Respiration rates and its relationship with ETS activity in euphausiids: implications for active flux estimations

Frontiers in Marine Science
Euphausiids, commonly known as krill, are crucial contributors to the ocean’s active carbon pump, impacting carbon export and sequestration through their diel vertical migration. These organisms feed on organic matter in the epipelagic layer at night and

Large deep-sea zooplankton biomass mirrors primary production in the global ocean

Nature Communications, 2020
Zooplankton biomass in the dark ocean is thought to be low and weakly coupled to epipelagic primary production, but recent evidence suggests otherwise.

Asymmetric Catch Distribution of Neon Flying Squid Across the Oyashio Extension Frontal Zone

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Mesoscale oceanic fronts are critical hotspots for marine productivity and fisheries, yet the fine‐scale mechanisms linking frontal dynamics to the specific distribution of catches remain poorly understood. This study investigates this link by analyzing a high‐resolution, decade‐long (2009–2021) fishery dataset for neon flying squid ...

Potential and expression of carbohydrate utilization by marine fungi in the global ocean

Microbiome, 2021
Background Most of the research on the cycling of carbon in the open-ocean has focused on heterotrophic prokaryotes and eukaryotic phytoplankton, but the role of pelagic fungi remains largely enigmatic.

Strong Purifying Selection Is Associated with Genome Streamlining in Epipelagic Marinimicrobia

Genome Biology and Evolution, 2019
Abstract Marine microorganisms inhabiting nutrient-depleted waters play critical roles in global biogeochemical cycles due to their abundance and broad distribution. Many of these microbes share similar genomic features including small genome size, low % G + C content, short intergenic regions, and low nitrogen content in encoded ...

Effects of Body Size and Environmental Region on the Nutritional Value of Small Pelagic Species in the California Current

Fisheries Oceanography, Volume 35, Issue 5, Page 722-736, September 2026.
ABSTRACT We evaluated the effects of regional environment and body size on the nutritional traits of five small pelagic species differing in habitat use, feeding behavior, and importance as prey for top predators in the California Current Large Marine Ecosystem (CCLME).

On catch of deep-sea shark Zameus squamulosus (Somniosidae, Squaliformes) in the epipelagic layer of the North-West Pacific

Известия ТИНРО, 2016
Two specimens of velvet dogfish Zameus squamulosus (TL 68.0 and 68.4 cm) caught in the epipelagic layer of the North-West Pacific are described, including morphometric parameters, number of vertebras, number of teeth rows, number of mitral valves, and ...

Interannual Variations in Distribution and Density of Japanese Anchovy (Engraulis japonicus) Larvae in the Shelf‐Break Region of East China Sea During Spring (2001–2022)

Fisheries Oceanography, Volume 35, Issue 5, Page 777-794, September 2026.
ABSTRACT Japanese anchovy (Engraulis japonicus) is the most abundant fish in the East China Sea (ECS) and an important fishery resource throughout its life stages. Using samples collected along the ECS shelf‐break in April over a 22‐year period (2001–2022), we examined the horizontal distribution and interannual variability of larval density (mean ...

Limited connectivity of zooplankton communities across the Labrador Front: role of physical oceanography, insights from individual motility

Oikos, Volume 2026, Issue 8, August 2026.
Near the western margin of the highly productive Labrador Sea, the Labrador Current creates a large and steep oceanographic front between the Arctic‐origin shelf waters and the Atlantic offshore waters (i.e. the Labrador Front), presumably segregating or accumulating plankton communities.
