Waters at the sill depths and near the bottoms of two basins off southern California were sampled in a grid pattern and analyzed for possible anomalies in temperature, salinity, and contents of oxygen, nutrients and suspended sediment due to turbidity currents. The only significantly anomalous patterns revealed were those of low salinity and high suspended sediment, atop a turbidity‐current apron opposite the mouths of two submarine canyons. This water was probably emplaced by turbidity currents, and its presence here indicates that areal variations of bottom‐water properties elsewhere warrant detailed studies.
