2014/4/16
I tested relationships between fish predator and prey densities or size across 66 lakes of the European temperate zone, covering mean depths between 1 and 22 m and a phytoplankton biomass range betwee...
Theoretical Aspects of Wind-Driven Currents in a Sea or Lake of Variable Depth with No Horizontal Mixing
Wind-Driven Currents Variable Depth with No Horizontal Mixing
font style='font-size:12px;'>
2009/4/3
Steady-state wind-driven circulations in a basin of variable depth, with only vertical turbulent mixing, are considered. The geostrophic flow away from the coast is determined for an arbitrary bottom ...

Large-Scale Circulation No Vertical Mixing Limit
font style='font-size:12px;'>
2008/10/27
By convention, the ocean’s large-scale circulation is assumed to be a thermohaline overturning driven by the addition and extraction of buoyancy at the surface and vertical mixing in the interior. Pre...
