Description:Direct observations of horizontal velocity divergence and relative vorticity were made in Shelikof Strait, Alaska during May 1990 with Loran-C buoys and satellite tracked drifters. These kinematic properties typically had values of 2 x 10-5 s-1. The horizontal divergence was a clearly defined, mesoscale process not apparently affected by turbulent diffusion. The divergence also appeared to be linked to the rise and fall of the pycnocline driven by an internal, semidaily tide. The data suggested that the net divergence over several days was quite small; thus larval concentration models can ignore this effect.
