Online seabed monitoring system operates in East China

BEIJING - An oceanic monitoring system is in stable operation in Penglai, East China's Shandong province, according to the National Ocean Technology Center Sunday.

The quantitative online monitoring and observation system was launched on June 24. It tests pH levels and concentration of dissolved oxygen which are influenced by temperature, salinity and water pressure, said Luo Xuye with the center.

Located 800 meters away from the shore, the system is expected to upgrade offshore sampling to continuous online monitoring, and improve ecological assessment.

The system's monitoring period ranges from one second to 30 minutes, depending on the subjects monitored.

Penglai is located at the northern tip of the Jiaodong Peninsula, where the Bohai Sea and the Yellow Sea meet.

The center plans to promote the system in other national ocean stations.
