Several aspects of feedback mechanisms associated with surf zone sandbar response have been characterized using bathymetric surveys, sampled approximately monthly over a 16-year period at the Army Corps of Engineers' Field Research Facility (North Carolina). The measured bathymetry was alongshore averaged and modeled by the superposition of two Gaussian-shaped sandbars...
Time series of satellite measurements are used to describe patterns of surface
temperature and chlorophyll associated with the 1996 cold La Nina phase and the 1997-1998
warm El Nino phase of the El Nino - Southern Oscillation cycle in the upwelling region off
northern Chile. Surface temperature data are available...
