Plankton Patchiness: Turbulent Transport, Spatial Spectra, and Continuum vs. Quantum
In this talk I will expand on two main points affecting our interpretation of spatial structures and trophic interactions of plankton in small-scale (<1 m) turbulent fields. 1) Spatial spectral slopes in biological properties such as chlorophyll should be interpreted with caution. Few instruments are capable of measuring biological quantities over these small scales the scales of individual interactions among the plankton. Furthermore, most such instruments measure quantities along a 1D profile; data must be properly manipulated prior to comparing the spectral slopes to 3D theoretical models. 2) New instruments, gathering 2D or 3D data, clearly show the non-continuous
