The vertical export of carbon and nitrogen caused by zooplankton diel vertical migration [PDF]

open access: yes, 2003
Fieldwork was conducted at three contrasting sites to test the applicability of an in situ technique (ZOOFLUX) for the assessment of the role of zooplankton diel vertical migration (DVM) in the removal of carbon and nitrogen from the surface layer of the ocean to the depths (the active flux).

Year‐Round Haulout Activity of Harbor and Gray Seals Derived From Satellite Telemetry in Scandinavian Waters

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Seal haulout behavior is of interest in relation to energetics and abundance estimation. To assess year‐round and diel haulout patterns and estimate correction factors, data were obtained from 100 seals (66 harbor and 34 gray seals) tagged with satellite transmitters in Kattegat and the western Baltic Sea during 2004–2017.

Lack of endogenous rhythmicity in Daphnia diel vertical migration [PDF]

open access: yes, 1993
A population of Daphnia galeata x hyalina was induced to perform diel vertical migration (DVM) by the addition of fish-kairomones to a large plankton tower. Vertical profiles of zooplankton abundance were measured every 12 h.

Listening to Bryde's Whales With an Island Seismometer: Low‐Frequency Call Detection and Seasonal Patterns Revealed by Deep Learning

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Bryde's whales form a major coastal aggregation in the Beibu Gulf, China. Using 1 year of continuous island‐based seismic recordings from Xieyang Island, we established a large labeled data set of coastal Bryde's whale calls with more than 1.7 million samples.

Variability in Diel Vertical Migration of Zooplankton and Physical Properties in Saanich Inlet, British Columbia [PDF]

open access: yes, 2013
In Saanich Inlet, a fjord located in southern Vancouver Island, British Columbia, dense aggregations of euphausiids exhibit diel vertical migration behavior and their capability of generating turbulence has been suggested. Despite decades of research on

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

open access: yesFrontiers 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.
