1 Plankton Patch Feasibility Experiments
Efforts this year focused on testing our model of the effects of episodic increases in current shear on the dynamics and impacts of thin layers of phytoplankton and zooplankton. Thin layers are plankton patches that range in thickness from a few tens of centimeters to a few meters, yet can be sufficiently intense to affect biological rate processes and the performance of current and planned Nav...
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 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...
