Status of the Benthos and its Environmental Parameters in Redskin Island, Mahatma Gandhi Marine National Park, Andaman and Nicobar Islands

摘要: The Redskin Island from the Mahatma Gandhi Marine National Park was monitored for coralline environment during period December 2008 to November 2009. Three belt transects were laid this study that cover north, south, and western sides of island. Since, eastern side a crocodile- prone area, transect not in area. environmental parameters studied every month continuously monitoring temperature, salinity, depth, pH, Eh, dissolved oxygen, turbidity, nitrite, nitrate, inorganic phosphate, silicate, on surface near sediment column waters year.
