Efficiency of water‐column light utilization in the subarctic northwestern Pacific
Efficiency of water‐column light utilization in the upper 2% light depth ( c) tended to be high during spring and summer (means: 0.75 and 0.96 g C g Chla −1 mol quanta −1 m 2 ) and low during autumn and winter (means: 0.33 and 0.53 g C g Chla −1 mol quanta −1 m 2 ). Higher phi values were probably d...

| Summary: | Efficiency of water‐column light utilization in the upper 2% light depth ( c) tended to be high during spring and summer (means: 0.75 and 0.96 g C g Chla −1 mol quanta −1 m 2 ) and low during autumn and winter (means: 0.33 and 0.53 g C g Chla −1 mol quanta −1 m 2 ). Higher phi values were probably due to an increase in the phytoplankton growth rate in the blooms. With the exception of bloom conditions, the phi tended to increase with a decrease of the daily photosynthetically active radiation (PAR), and variations in the phi in relation to the daily PAR were within the range of those summarized by Falkowski and Raven (1997). The water‐column light utilization efficiency in the subarctic northwestern Pacific at the bloom times was noticed to be by far the highest in the world oceans. |
