Diel vertical migration (DVM) is a widespread behaviour among many pelagic species, from
zooplankton to sharks and has been widely studied in both marine and freshwater …

The deep scattering layer is an ubiquitous aggregation of zooplankton and forage fish in the
ocean. It features the striking phenomenon of diel vertical migration, where animals remain …

Advances in satellite tracking and archival technologies now allow marine animal
movements and behavior to be recorded at much finer temporal scales, providing a more …
