Abstract:

During 1993.12￣1994.2, the COD Mn of the Great Wall Bay, Antarctica and its adjacent sea areas was investigated. The COD Mn of 39 stations was from 0.3342 mg/L to 1.9590mg/L; the high value was at the research stations, and the value of the inner Great Wall Bay was higher than that of the outside. The reason of the change of the COD Mn was studied; the main resource of the COD Mn was analysed.Some of the pollution comes from the research stations,but most of it may come from the living beings. The wind and wave is one of the most important factors affect the values of COD Mn . Suggestions were given to protect the environment of Antarctica.
