Science triumph hit multiple home for the first time the Western Pacific expedition test success

"Science" triumph hit multiple home for the first time: the Western Pacific expedition test success source: Science and technology daily 30 on the morning of 8, China’s new generation of integrated marine science research ship science "arrived in the Research Institute of Qingdao ocean Chinese Xuejiadao pier, marking the 2016 Western Pacific Scientific Research Test Study on joint voyage success, and create multiple first. For the first time to obtain the Philippines Sea basin average depth 5000m complete the full depth temperature, salinity, pressure, dissolved oxygen and nutrients to the cross section data. The data provide valuable data for the study of deep ocean circulation and its response to global warming. The first hundred percent recovery of China’s first "Western Pacific deep-sea pressure inverted echo sounder (PIES) observation array, the array observation and access to the success of West Pacific low latitude flow fixed point observation data for 25 consecutive months. This project is based on Yuan Dongliang, a leading scientist and a major national scientific research program. This voyage chief scientist Dr. Zhou Hui led the task force in the crew and the engineering department’s help, successfully recovered the cloth from the Western Pacific North Equatorial current and North Equatorial Countercurrent Road District 5000m to three PIES deep. PIES is a pressure sensor based on the bottom of the ocean observation equipment, used to observe the acoustic signal from the seabed to the sea vertical transmission time (VATT) and sea bottom pressure changes. The PIES observation array placed in September 1, 2014, more than two years of continuous work, the successful observation occurred during 2016 2014 – Super El Nino La nina. The obtained data is of great significance for the study of the occurrence and development mechanism of the El Nino event, which has important reference value for the future more accurate prediction of this climate anomaly. For the first time to get a Western Pacific full depth trace element sampling; team led the voyage with East China Normal University academician Zhang successfully acquired the trace elements in samples of Philippines Sea basin depth of more than 5000m. For the first time, a high throughput sequencing technique was used to obtain the diversity of micro and Pico eukaryotic plankton samples in the Western Pacific ocean. The success of the test of 3 independent research and development of underwater glider, the total number of days to reach 48 days, get the upper 1000m of the marine elements (temperature, salinity, pressure, dissolved oxygen, chlorophyll) data.相关的主题文章:
