Abstract

Steady-sate upwelling of homogeneous water over a shelf break is considered. The bathymetry used consists of separate shelf and slope sections which have been smoothly connected at the shelf break. Garvine's theory for upwelling over smooth bathymetries is modified for this investigation. The principal physical effects attributed to the presence of the shelf break are 1) the existence of a secondary upwelling zone located just seaward of the shelf break and close to the bottom, and 2) the existence of a circulation cell above the continental slope.
