[Effects of hydrodynamic process on bio-optical properties in algal-dominated lake region of shallow lake].

An in situ field high-frequency bio-optical measurement was carried out in the littoral region in Meiliang Bay of Lake Taihu, a large shallow lake of China from 24 July to 1 August in 2010. The underwater irradiance, beam attenuation coefficient and absorption coefficient, the related physical-chemical and meteorological parameters were measured and analyzed, in order to determine the relationship between water bio-optical properties and wind waves process. The absorption coefficients of particles a(p) (440), non-phytoplankton a(d) (440), phytoplankton a(ph) (440) and chromophoric dissolved organic matter (CDOM) a(CDOM) (440) were 3.
