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

Respiration Rates in the Global Mesopelagic Ocean

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Respiration in the mesopelagic layer of the oceans (200–1,000 dbar) is a key factor controlling the biological carbon pump, as it attenuates the downward flux of organic carbon to the ocean interior. Using a global data set of dissolved oxygen and transient tracer gas measurements, we report spatially resolved oxygen utilization rates (OUR ...

Physical oceanography, abundance, biomass and respiration data of fishes (Stomiiformes) from the BATHYPELAGIC cruise (June 2018) to the Northeast Atlantic Ocean

, 2022
Physical oceanography variables and carbon remineralisation (juveniles/adults of Cyclothone species and Argyropelecus hemigymnus) were analysed during the BATHYPELAGIC cruise (North Atlantic, June 2018).

Niche Differentiation of Aerobic and Anaerobic Ammonia Oxidizers in a High Latitude Deep Oxygen Minimum Zone

Frontiers in Microbiology, 2019
To elucidate the potential for nitrification and denitrification processes in a high latitude deep oxygen minimum zone (OMZ) we determined the abundance and community composition of the main microbial players in the aerobic and anaerobic (anammox ...

Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

Journal of Fish Biology, Volume 108, Issue 4, Page 1150-1169, April 2026.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Unveiling the phylogenetic position of the type species of the syndinean genus Amoebophrya and broad divergence of the A. ceratii complex

Journal of Phycology, Volume 62, Issue 2, Page 689-702, April 2026.
Abstract The syndinean genus Amoebophrya comprises endoparasitic dinoflagellates that infect various marine protists. Since the description of the type species, A. sticholonchae, a parasite of the radiolarian Sticholonche zanclea, an additional six Amoebophrya species have been formally described.

Standard length, weight, body mass-density and swim bladder measurements data of Cyclothone species from the IDEADOS, BATHYPELAGIC and SUMMER cruises in Northeast Atlantic Ocean and Mediterranean Sea

, 2023
Size, weight, body-mass density and swim bladder measurements of Cyclothone species were analysed during the IDEADOS (Mediterranean Sea, July 2010), Bathypelagic (North Atlantic, May-June 2018) and SUMMER (Mediterranean Sea and North Atlantic, September ...

Comparison of Environmental DNA Metabarcoding and Trawl Data Highlights Gear Selectivity of Marine Demersal Fish Surveys on the Faroese Plateau

Environmental DNA, Volume 8, Issue 2, March/April 2026.
The study compared trawl and eDNA metabarcoding of demersal fish communities in an open ocean environment around the Faroe Islands. eDNA provided a comparable assessment of demersal species biomass and revealed additional spatial information on keystone species known to be under‐sampled by demersal trawls due to size and behavioral traits.

Environmental DNA Reveals Diverse and Depth‐Stratified Biodiversity in East Indian Ocean Submarine Canyons

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Environmental DNA metabarcoding reveals diverse animal communities across Cape Range and Cloates submarine canyons off Western Australia. Two assays detected 234 species spanning 125 families across 11 phyla, highlighting canyon‐specific assemblages and demonstrating the value of eDNA for establishing biodiversity baselines in remote and poorly ...

Zooplankton faecal pellet transfer through the meso- and bathypelagic layers in the Southern Ocean in spring

, 2016
The faecal pellets (FP) of zooplankton can be important vehicles for the transfer of particulate organic carbon (POC) to the deep ocean, often making large contributions to carbon sequestration.
