Delineating Marine Planktonic Habitats Through the Biogeochemical‐Argo Array Data

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Phytoplankton play a crucial role in regulating marine biogeochemical pathways but studying their spatial and temporal dynamics often requires extensive and laborious oceanographic expeditions. Here, we report a novel use of Biogeochemical‐Argo data to delineate planktonic habitats in the Tropical North Atlantic Ocean (TNA).

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

open access: yesFrontiers 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

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

open access: yesИзвестия 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 ...

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

open access: yesNature 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.

Rare occurrence of Reinhardt’s cranch squid Liocranchia reinhardti (Cephalopod: Cranchiidae) from southeastern Arabian Sea [PDF]

open access: yes, 2017
Single individual of the rare cranchiid squid Liocranchia reinhardti belonging to the Cranchiidae family was caught in a bottom trawl operated at 80 m in southeastern Arabian Sea. The morphometric measurements and indices of the specimen are provided.

Diversity and Ecological Potentials of Marine Viruses Inhabiting Continental Shelf Seas

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
To the best of the knowledge, this study provides the largest viral genome dataset from a continental shelf sea. It reveals that over half of vOTUs are novel, highlighting the remarkable viral novelty in the eastern continental shelf seas of China (ECSSC).

Only One Percent of Important Shark and Ray Areas in the Western Indian Ocean Are Fully Protected From Fishing Pressure

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Delineation of Important Shark and Ray Areas (ISRAs) In the Western Indian Ocean was enhanced by the verification and incorporation of unpublished records. Even with this expanded dataset, ~99% of ISRA coverage fell outside of fully protected, no‐take MPAs.

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

open access: yesMicrobiome, 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.

Major contribution of particle‐associated microbes to deep‐sea organic carbon degradation

open access: yesLimnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract The biological carbon pump mediates the export of particulate organic carbon from the euphotic zone to the deep ocean, where it provides the base of the food web. Although deep‐sea microbial metabolism is considered to be largely associated with macroscopic particles, such as marine snow, the specific contribution of particle‐associated ...
