Paper Abstract

By using MODIS data, we investigated the spatial and temporal variation of the attenuation depths (Z90) in the Bohai Sea. While Z90 was highly variable, it increased from the nearshore to the central Bohai Sea. In the Laizhou Bay, Liaodong Bay and Bohai Bay, Z90 was less than 4.5 m, mostly below 3m; while Z90 increased in the northern Bohai Straits, the western Liaodong Bay estuary, and the central Bohai Sea. This spatial pattern has been consistent with the findings reported by several previous studies. Moreover, the wavelength of the maximum Z90 shifted toward longer wavelengths when the water turbidity increased in the Bohai Sea. We also found that the Z90 varied by seasons. The maximum Z90 occurred in summers but the minimum Z90 may be in springs or winters.
