Radial electron heat transport in low collisionality, magnetically-confined toroidal plasmas is shown to result from paleoclassical Coulomb collision processes (parallel electron heat conduction and magnetic field diffusion). In such plasmas the electron temperature is equilibrated along magnetic field lines a long length L (>> periodicity length πR0q), which is the minimum of the electron coll...

Abstract In the stratified ocean, vertical eddy diffusivity in subsurface pycnocline plays a major role new production through transporting nutrients upwards from darker/nutrient-rich layer. order to evaluate that was less available layers where indirect estimations are difficult, we conducted direct microstructure measurements upper 300 m of open Pacific during summer, 40°S 50°N along 170°W an...
