Kelvin-wave turbulence generated by vortex reconnections

Reconnections of quantum vortex filaments create sharp bends which degenerate into propagating Kelvin waves. These waves cascade their energy down-scale and their waveaction up-scale via weakly nonlinear interactions, and this is the main mechanism of turbulence at the scales less than the inter-vortex distance. In case of an idealised forcing concentrated around a single scale k0, the turbulen...

Plankton sinking and turbulence

To overcome sinking, plankton have devised various types of strategies. One is swimming, that is, an active, energy-consuming self-propulsion than can oppose gravitational sinking. Other phytoplankters can modify their buoyancy, becoming, at least for some time, positively buoyant. Others can exploit the turbulence in the mixed layer, using it to stay suspended for longer times. This latter opt...

Plankton dynamics and mesoscale turbulence

In aquatic ecosystems, primary production (the transformation of inorganic materials and light into living matter by photosynthesis) is operated mainly by small, unicellular algae that float freely in the upper layers of oceans and lakes and are collectively called phytoplankton, see for an illustration the phytoplankters depicted in figure 1. Since phytoplankton need light, they are confined t...

Hydrodynamic Stimulation of Plankton Bioluminescence

Fish do it. Dolphins do it. Swimmers do it. Surface ships do it. In fact, the last German U-boat detected in the Great War was sunk because it did it. What they all do is create flow fields energetic enough to create bioluminescent "footprints." Because bioluminescent organisms are ubiquitous (particularly dinoflagellates, common members of marine plankton) flow-stimulated light emission repres...

Synthetizing hydrodynamic turbulence from noise: Formalism and applications to Plankton dynamics

We present an analytical scheme, easily implemented numerically, to generate synthetic Gaussian 2D turbulent flows by using linear stochastic partial differential equations, where the noise term acts as a random force of well-prescribed statistics. This methodology leads to a divergencefree, isotropic, stationary and homogeneous velocity field, whose characteristic parameters are well reproduce...
