Phytoplankton conditions were examined at two stations off the leeward coast of Oahu, Hawaii. Significant temporal variability was observed in the chlorophyll and pheopigment data. Significant temporal and spatial variability was observed in the ATP and productivity data. Dissimilar inflection depths for nitrate, phosphate, and silicate indicate nitrate availability and phosphate limitation in the lower photic zone. Production between January and May was 11 times that between May and November; productivity below 44 m accounted for most of this variation. Biological and physical analyses indicate that variations in vertical nutrient supply, related to differences in current shear, caused this temporal variaton.
