Apparent oxygen increase (AOI) and its application in rapid　assessment and prewarning of red tide in coastal waters;

The aquatic environment in the coastal waters is the important components of the coastal ecosystem.

The whole process of environmental monitoring in coastal waters was commented,including preparation before sampling,working out sampling plan,assignation of monitoring station,sample collection,storing and transportation,the analysing,data dealing and transportation in the lab.

This paper analyzed water quality feature of coastal area in Jinzhou using the composite pollution index method based on eight monitoring sites near the coast and the whole area in 2004 and 2005.

Recently, the thermal discharge from the plant of coastal areas will affect the adjacent water in physics, chemistry, biology and so on, People pay more attention to this temperature affection.

At present,effect of ocean engineering on environment in Lianyungang Coastal area is environmental impact assessment for single project, the research on the effect of multi-ocean engineering on ocean water quality, sediment and biology has not been carried out so far.
