Detailed vertical profiles of salinity, temperature, oxygen, nitrate, phosphate, nitrite, and silicate have been taken on 6 cruises over a 14‐month period in the Santa Barbara basin. In May 1970, during intense upwelling, nitrate content basin water from sill (475 m) to bottom (580 showed significant changes their normal conditions: oxygen increased 0.05–0.10 ml/ liter 0.35–0.43 ml/liter; concentration, which previously decreased markedly below due reduction little reduction; temperature by 0.14–0.19C. The results 2 subsequent June July 1970 kinetically follow back its conditions. After months had almost returned with measured average consumption rate 1.3 ml −1 yr , while rose at 0.02–0.04C/ month. These data indicate that was flushed out seawater coming sill. This first direct evidence for flushing any California suggests oceanography is dynamic it capable shorter time scale than thought.
