Bacterial productivity in the Prydz Bay and its adjacent waters, Antarctic
Bacterial productivity was measured using (3)H-thymidine methods in the Prydz Bay and its adjacent waters in the Southern Ocean during the 16th National Antarctic Research Expedition of China (CHINARE). The results showed that bacterial productivity in our study areas ranged from 4.5 to 191 ngC * dm...
