Optimization of a micronekton model with acoustic data [PDF]
ICES Journal of Marine Science, 2014 Abstract In the pelagic foodweb, micronekton at the mid-trophic level (MTL) are one of the lesser known components of the ocean ecosystem despite being a major driver of the spatial dynamics of their predators, of which many are exploited species (e.g. tunas).

State of Satiation Partially Regulates the Dynamics of Vertical Migration
Frontiers in Marine Science, 2021 Vertical migrations into shallower waters at night are beneficial for migrators as they reduce predation risk and allow migrators to encounter a higher density of prey.

Dead zone or oasis in the open ocean? Zooplankton distribution and migration in low-oxygen modewater eddies [PDF]
, 2015 The eastern tropical North Atlantic (ETNA) features a mesopelagic oxygen minimum zone (OMZ) at approximately 300–600 m depth. Here, oxygen concentrations rarely fall below 40 µmol O2 kg−1, but are expected to decline under future projections of global ...
