The distribution of suspended sediment and plankton throughout the upper 275 m of water over San Pedro Basin, California, was observed on 4 cruises in 1957–58. In general, plankton concentrations varied inversely with depth while suspended sediment concentrations varied inversely with distance from shore. On 3 of the cruises, localized high concentrations of 2‐ µ diameter sediment were found near the bottom at depths between 200 and 275 m. Evidence of entrainment and subsequent sinking of plankton along with the suspended sediment suggests turbidity currents originating within the upper 50 m on the continental shelf.
