In order to meet the requirements of fast and multi-factors monitoring of the marine environment, a kind of shipborne automatic sampling system (SASS) was developed. SASS has a simple and flexible operation system, and has three control modes: automatic, semi-automatic and manual mode. The hardware of SASS mainly consists of pump, composite cable, electric winch, electric control cabinet and storage tank. With the control of the software, the devices such as winch and collecting pump can open and close automatically, to complete the collection of multi-level seawater samples in same site. Compared with the traditional method, this system can greatly reduce the labor intensity of the experimenters, and improve the precision of sampling depth. After a large number of sea trials in the Bohai Sea and in the East China Sea, SASS has been proved to be stable.
