From the 1860s into the 1920s Edward Sylvester Morse (1838-1925) was a staunch advocate of Darwinian evolution and of science education in the U. S. and likewise for several years in Japan. He had a major impact on the American public’s understanding of evolution, both before and after he became...
A reexamination of turbulence dissipation measurements from the equatorial Pacific shows that the turbulence diffusivities are not a simple function of the gradient Richardson number. A widely used mixing scheme, the K-profile parameterization, overpredicts the turbulent vertical heat flux by roughly a factor of 4 in the stably stratified region...
In north and central California, equatorward winds drive equatorward flows
and the upwelling of cold dense water over the shelf during the midspring and summer
upwelling season. When the winds temporarily weaken, the upwelling flows between
Point Reyes and Point Arena ‘‘relax,’’ becoming strongly poleward over the shelf.
Analytical and...
