The optimal spectral decomposition (OSD) method is used to reconstruct seasonal variability of the Black Sea horizontally
averaged chlorophyll-a concentration from data collected during the NATO SfP-971818 Black Sea Project in 1980–1995. During
the reconstruction, quality control is conducted to reduce errors caused by measurement accuracy, sampling strategy, and irregular
data distribution in space and time. A bi-modal structure with winter/spring (February–March) and fall (September–October)
blooms is uniquely detected and accurately documented. The chlorophyll-a enriched zone rises to 15 m depth in winter and June,
and deepens to 40 m in April and 35 m in August. The June rise of the chlorophyll-a enriched zone is accompanying by near continuous
reduction of upper layer maximum chlorophyll-a concentration.
