Abstract

Broadly distributed measurements of velocity, density, and turbulence spanning the inner shelf off central California indicate that (i) the average shoreward-directed internal tide energy flux <F_E > decreases to near 0 at the 25-m isobath; (ii) the vertically integrated turbulence dissipation rate <D> is approximately equal to the flux divergence of internal tide energy ∂_x <F_E >; (iii) the ratio of turbulence energy dissipation in the interior relative to the bottom boundary layer (BBL) decreases toward shallow waters; (iv) going inshore, <F_E > becomes decorrelated with the incoming internal wave energy flux; and (v) <F_E > becomes increasingly correlated with stratification toward shallower water.
