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

Frontiers 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.

Prokaryotic abundance and heterotrophic metabolism in the deep Mediterranean Sea

Advances in Oceanography and Limnology, 2010
A synthesis of field data carried out in the Mediterranean Sea are presented, aimed at contributing to the knowledge of three prokaryotic-mediated processes and their implications on the Carbon cycle.

Dynamic Sinking and Surface‐Area Based Decay Modeling Reduce Estimates of Gelatinous Zooplankton‐Mediated Carbon Export to the Deep Sea

Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract Gelatinous zooplankton (GZ) have been proposed as a potentially important but largely overlooked contributor to the biological carbon pump. However, estimates of GZ‐derived carbon transfer efficiency to the ocean floor reflect uncertainties in key parameters that govern carbon export, leading to contrasting interpretations of the role of GZ in

Meso- and Bathypelagic Fish Interactions with Seamounts and Mid-Ocean Ridges [PDF]

, 2007
The World Ocean\u27s midwaters contain the vast majority of Earth\u27s vertebrates in the form of mesoand bathypelagic (\u27deep-pelagic,\u27 in the combined sense) fishes.

Climate Change, Local Harvests and Marine Contamination: A Perspective on Cetacean Populations and Coastal Whaling Communities

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Cetaceans are indicators of ocean health, influence marine ecosystem dynamics and hold socio‐economic importance for coastal whaling communities. Yet whale–whaler relationships remain poorly understood and are increasingly compromised under the triple planetary crisis of climate change, biodiversity loss and pollution. Here, we briefly outline

Genomic signatures of fifth autotrophic carbon assimilation pathway in bathypelagic Crenarchaeota [PDF]

Microbial Biotechnology, 2010
Summary Marine Crenarchaeota , ubiquitous and abundant organisms in the oceans worldwide, remain metabolically uncharacterized, largely due to their low cultivability. Identification of candidate genes for bicarbonate fixation pathway in the Cenarchaeum ...

Diel transcriptional response of a California Current plankton microbiome to light, low iron, and enduring viral infection. [PDF]

, 2019
Phytoplankton and associated microbial communities provide organic carbon to oceanic food webs and drive ecosystem dynamics. However, capturing those dynamics is challenging. Here, an in situ, semi-Lagrangian, robotic sampler profiled pelagic microbes at

Mapping Mediterranean bentho‐demersal communities to better inform marine conservation

Conservation Science and Practice, Volume 8, Issue 2, February 2026.
Marine protected areas are one of the most common conservation tools being implemented worldwide to reach conservation targets, but their implementation does not usually take the heterogeneous distribution of bentho‐demersal communities into account.

Deep ocean metagenomes provide insight into the metabolic architecture of bathypelagic microbial communities

Communications Biology, 2021
Silvia Acinas et al. report the Malaspina Gene Database, a gene catalogue from deep ocean microbes and the Malaspina Deep Metagenome-Assembled Genomes (MAGs) which is made publicly available. The analysis of the metabolic pathways within these MAGs sheds
