Empirical leucine-to-carbon conversion factors in north-eastern Atlantic waters (50–2000 m) shaped by bacterial community composition and optical signature of DOM

open access: yesScientific Reports, 2021
Microbial heterotrophic activity is a major process regulating the flux of dissolved organic matter (DOM) in the ocean, while the characteristics of this DOM strongly influence its microbial utilization and fate in the ocean.

Life History of the Arctic Squid Gonatus fabricii (Cephalopoda: Oegopsida) Reconstructed by Analysis of Individual Ontogenetic Stable Isotopic Trajectories

open access: yesAnimals, 2022
Cephalopods are important in Arctic marine ecosystems as predators and prey, but knowledge of their life cycles is poor. Consequently, they are under-represented in the Arctic ecosystems assessment models.

Mountains in the Sea: Fishy Deep-sea Designs [PDF]

open access: yes
In this activity, students will focus on adaptations of fishes living in the mesopelagic and bathypelagic zones of the deep ocean. The students will learn about the physical location of deep water habitats along the Hudson Shelf Valley and in Hudson ...

Lytic viral infection of bacterioplankton in deep waters of the western Pacific Ocean [PDF]

open access: yes, 2014
As the most abundant biological entities in the ocean, viruses influence host mortality and nutrient recycling mainly through lytic infection. Yet, the ecological characteristics of virioplankton and viral impacts on host mortality and biogeochemical ...

Contribution of Bicarbonate Assimilation to Carbon Pool Dynamics in the Deep Mediterranean Sea and Cultivation of Actively Nitrifying and CO2-Fixing Bathypelagic Prokaryotic Consortia

open access: yesFrontiers in Microbiology, 2018
Covering two-thirds of our planet, the global deep ocean plays a central role in supporting life on Earth. Among other processes, this biggest ecosystem buffers the rise of atmospheric CO2.

Additional Records of Deep-Sea Fishes from Off Greater New England [PDF]

open access: yes, 2008
Recent review of deep-sea fishes captured deeper than 200m off greater New England, from the Scotian Shelf at 44°N to the southern New England Shelf at about 38°N, documented 591 species.

Diversity and distribution of marine heterotrophic bacteria from a large culture collection

open access: yesBMC Microbiology, 2020
Background Isolation of marine microorganisms is fundamental to gather information about their physiology, ecology and genomic content. To date, most of the bacterial isolation efforts have focused on the photic ocean leaving the deep ocean less explored.

Vertical and longitudinal gradients in HNA-LNA cell abundances and cytometric characteristics in the Mediterranean Sea [PDF]

open access: yesBiogeosciences, 2011
Heterotrophic bacterioplankton abundance and production were investigated with depth (down to bathypelagic layers) and with longitude (from 4.9° E to 32.7° E) along a cruise track across the Mediterranean Sea in early summer 2008.
