Plankton blooms induced by turbulent flows.
Plankton play an important role in the ecology of the ocean and the climate because of their participation in the global carbon cycle at the base of the food chain. However, damaging plankton blooms can sometimes occur and are initially characterized by sudden transient increases in the phytoplankton population. They are thought to be driven by several effects, such as seasonal variations in te...
متن کاملPlankton lattices and the role of chaos in plankton patchiness.
Spatiotemporal and interspecies irregularities in planktonic populations have been widely observed. Much research into the drivers of such plankton patches has been initiated over the past few decades but only recently have the dynamics of the interacting patches themselves been considered. We take a coupled lattice approach to model continuous-in-time plankton patch dynamics, as opposed to the...
متن کاملPlankton cooled a greenhouse
experiments are lucky — a megalomaniac climatologist can only dream of putting an Earth-like planet in a giant test tube, pumping billions of tonnes of CO2 into its atmosphere, and registering the effects on life and climate. Fortunately, there are other approaches. At the Palaeocene/Eocene (P/E) boundary 55 million years ago, nature appears to have done the greenhouse experiment for us. Bains ...
متن کاملPlankton Patch Feasibility Experiments
The long term goal is to increase our understanding of the biological biological, physical biological and chemical biological interactions that control the initiation, maintenance and dissipation of plankton patches. This goal can most readily be achieved by directly measuring processes thought to control plankton patch dynamics, experimentally testing their importance, incorporating those proc...
متن کاملPlankton 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...
