[Photo/VCG] Two Chinese submersibles finished a three-day joint operation, the first of its kind in the country's deep sea exploration, to detect a cold seep in the Pearl River Mouth Basin in the South China Sea. Unmanned submersible Haima, or seahorse, and manned submersible Shenhai Yongshi, or deep sea warrior, on board scientific survey ships Haiyang 6 and Tansuo 1 respectively, carried out the joint operation from April 28 to 30. They are both the major domestically developed deep-sea vehicles and set an example of how to master key technology in deep sea exploration, to swiftly use scientific research results for real benefit and to put domestic high-tech equipment into practical use. The two submersibles conducted three dives together to reach the cold seep located in the South China Sea named after one of them, Haima, who discovered it in March 2015. Haima took samples from and explored the cold seep by making use of multiple tools it is equipped with, such as drill, side scan and side-imaging sonar, methane sensor and trap for undersea creatures. Shenhai Yongshi showed its functionality and ability to obtain precise data about the total area and topographic features of the cold vent. A cold seep is an area of the ocean floor where hydrogen sulfide, methane and other hydrocarbon-rich fluid seepage occurs, often in the form of a brine pool. Research on Haima cold seep could shed light on natural gas hydrate reservoir forming, the ecosystems of cold seeps and even the origins of life on earth. The two submersibles also inspected and recorded each other's operations during the joint expedition. wristbands canadacustom silicone bracelets canadarubber bracelets canadasilicone bracelets canadasilicone wristbands canadacustom wristbands canadacanadian wristbandswristbands canada
BEIJING -- The Chinese Academy of Sciences Institute of Atmospheric Physics and Laoting County have reached an agreement to build an atmosphere and marine research station and an industrial base in this north China county.The current limited shore-based and island weather stations, floating stations, merchant ship weather report and aviation monitoring report cannot satisfy the scientific research demand, according to a report on the China Science Daily. Thus the offshore observation platform is needed to conduct continuous ocean meteorological observation covering long distances with high endurance under severe meteorological conditions.The station will have a shore-based remote observation and control center, while the industrial base will have assembly lines of unmanned ships and drones.At the industrial base, an unmanned smart technical team will conduct marine weather and hazard research.Laoting County has over 100 km of coastline, 25 percent of the total coastline length of Hebei Province.
