Effect of ultraviolet radiation on marine phytoplankton community was determined during a spring and fall bloom in a boreal embayment, Akkeshi Bay, Japan, which was located at 43[degrees]N, 144[degrees]50[prime]E. A time-series of observation was made every 6 h for 24 hours. Exposure to ultraviolet radiation always caused a depression of photosynthetic activity was observed at the end of day light period in both blooms. During a nigh period a degree of depression was decreased by 50% at least. The results of the present study may suggest that the effect of ultraviolet radiation on photosynthesis of marine phytoplankton is significantly large even in the boreal sea region and marine phytoplankton community has a capability to recover more than 40% from a damage by ultraviolet radiation during a night period.
