Trophic Structure and Sources of Variation Influencing the Stable Isotope Signatures of Meso- and Bathypelagic Micronekton Fishes

Frontiers in Marine Science, 2020
To better understand spatiotemporal variation in the trophic structure of deep-pelagic species, we examined the isotope values of particulate organic matter (POM) (isotopic baseline) and seven deep-pelagic fishes with similar diet compositions but ...

Acoustic evidence for topographic blocking on a steep submarine canyon wall

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Diel vertical migration (DVM) is the largest mass‐movement of animals on Earth, with profound ecological and biogeochemical consequences. DVM has mostly been studied in the open ocean; however, at steep slopes, pelagic animals including vertical migrators must contend with the seafloor, emphasizing the importance of understanding DVM in these ...

The Deep‐Sea Preyscapes of Mammalian Top Predators

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Deep‐sea predator foraging is shaped by prey richness, accessibility, and density. Using eDNA and acoustics, we mapped fish and cephalopod communities across inshore‐offshore gradients around the Azores in foraging habitats of three co‐occurring deep‐diving toothed whales.

Meso‐ to Submesoscale Variability of Particulate Carbon Export Captured by a Glider‐Camera System in the Northeast Atlantic During the APERO Campaign

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Between 9 June and 6 July 2023 a SeaExplorer glider equipped with an Underwater Vision Profiler (UVP6), surveyed frontal structures between a cyclonic and two anticyclonic eddies in the Northeast Atlantic as part of the APERO cruise (Assessing marine biogenic matter Production, Export and Remineralization: from the surface to the dark Ocean ...

Great Meteor Seamount Circulation Revisited: Insights Into Cold‐Water Coral Habitat Potential

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Seamounts play a crucial role in shaping deep‐sea ecosystem structure, influencing ocean circulation, enhancing biological productivity, and supporting diverse marine life. The Great Meteor Seamount (GMS), is the largest seamount in the North Atlantic and a key ecological feature in the regional network of the Protected Areas of the Azores ...

Ecology and Seasonal Habitat Use of Northern Bottlenose and Sowerby's Beaked Whales in the Azores

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Beaked whales are among the least known cetaceans, yet they are regularly observed in the Azores, a region recognized as a hotspot for deep‐diving species. In this study, we analyzed opportunistic sightings collected during 1492 whale‐watching trips, including 149 beaked whale encounters, of which 89 were Sowerby's (Mesoplodon bidens) and 31 ...

Stable isotope patterns in micronekton from the Mozambique Channel [PDF]

Deep Sea Research Part II: Topical Studies in Oceanography, 2014
Abstract We measured the stable carbon (δ 13 C) and nitrogen (δ 15 N) isotopic composition of tissues of micronektonic organisms (fishes, squids, crustaceans and gelatinous organisms) collected in the Mozambique Channel during two scientific cruises in 2008 and 2009. The oceanic circulation in the Mozambique Channel is dominated by mesoscale cyclonic

Aotearoa New Zealand’s marine carbon cycle in a changing climate – Current understanding and future directions

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 913-956, December 2025.
ABSTRACT The marine system plays a critical role in the global climate cycle, as a major control of atmospheric carbon dioxide (CO2). Marine primary production (photosynthesis) and remineralisation of organic carbon (respiration, degradation) determine the amount of CO2 sequestered in marine sediments and deep‐water environments on century to ...

Microbial and Metazoan Activity in Monterey Bay, CA Recorded in Nitrogen Isotope Ratios of Sinking and Suspended Particles

Journal of Geophysical Research: Oceans, Volume 130, Issue 10, October 2025.
Abstract Particulate organic matter supports pelagic food webs, and the activity of these food webs attenuates the flux of carbon into the ocean interior. Understanding the extent to which microbial and metazoan heterotrophs influence particle dynamics is essential to describing the biological carbon pump and nutrient delivery to deep ecosystems.
