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.

Previously Unrecognized Land‐Use Control on Deep Soil CO2 Sink

Global Change Biology, Volume 32, Issue 10, October 2026.
Transport‐limited, boundary‐conditioned bidirectional exchange of topsoil‐respired CO2 drives CO2 accumulation in less bioactive subsoils in concentrations that cannot be explained by in situ production alone and far exceed atmospheric boundary concentrations, revealing a production‐transport imbalance and a potential land‐use‐sensitive pathway for ...

Kogia Records in Brazilian Equatorial and Southwestern Atlantic Oceans

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The pygmy (Kogia breviceps) and dwarf (Kogia sima) sperm whales are cryptic cetaceans characterized by inconspicuous surfacing behavior, small group sizes, and deep‐diving habits, making visual detection particularly challenging. Here, we present the first broad‐scale passive acoustic monitoring (PAM) assessment of Kogia spp.

Seasonal and Diel Acoustic Occurrence of Sei Whales in Oregon, USA

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The behavior, distribution, and life history of sei whales (Balaenoptera borealis) are largely unknown in the North Pacific. We analyzed data from three bottom‐mounted acoustic recorders deployed 25 (shelf; depth = 300 m), 45 (slope; depth = 630 m), and 65 (abyssal; depth = 2860 m) nautical miles off of Newport, Oregon, USA that recorded ...

Characterizing Habitat Suitability of Long‐Finned Pilot Whales in a Key Conservation Region of the Southern Iberian Peninsula Using Satellite Tracking Data

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The waters surrounding the southern Iberian Peninsula are a key conservation area for the long‐finned pilot whale (Globicephala melas melas), particularly in the pelagic regions of the Strait of Gibraltar, the Alboran Sea, and the Gulf of Vera, where upwelling, complex bathymetry and frontal dynamics enhance productivity and prey availability,

Unexpected Global Prevalence of Mesopelagic Particle Layers Detected by BGC‐Argo Floats

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Particulate organic carbon transported to the deep ocean forms a critical component of the Earth's carbon cycle. The concentration of these particles is generally parameterized in models to decrease continuously with depth, but isolated layers of small particles (≤ ${\le} $20 μm ${\upmu }\mathrm{m}$) observed within the mesopelagic challenge ...

The selective advantage of diel vertical migration behavior in juvenile sockeye salmon and kokanee (Oncorhynchus nerka)

, 1989
The widespread occurrence of diel vertical migration behavior in pelagic aquatic organisms suggests that there is a selective advantage of the behavior compared to a static vertical depth distribution in the water column.
