Preliminary Investigation on Vertical Distribution of Phytoplankton Biomass and Nutrients in Tasik Biru (Blue Lake), Bau, Sarawak.

Located in Bau district, Sarawak, Tasik Biru, formed from an open cast gold mining pit, was opened to the public as recreational area in 2001. Due to the gold mining activities, the water contains high content of arsenic as declared by Natural Resources and Environmental Board (NREB) of Sarawak. The...
