The Pacific Ocean buoy really exists.
Chinese researchers from the Third Institute of Oceanography of the Ministry of Natural Resources (MNR) deployed a buoy for the first time in the easternmost part of the Pacific Ocean on Oct. 20 aboard the research vessel Xiangyanghong 03 to carry out a summer voyage to investigate global changes and sea-air interactions in the North Central Pacific Ocean. On October 20, scientific researchers from the Third Institute of Oceanography of the Ministry of Natural Resources (MNR) aboard the research vessel "Xiangyang Hong 03" successfully deployed a set of multifactorial integrated deep-sea buoys under China's management and independent research and development in the waters of the North and Central Pacific Ocean during the summer voyage of the 2019 Comprehensive Survey of Marine Environment and Waters in the North and Central Pacific Ocean for the special project of "Global Changes and Sea-Air Interactions.
The buoy is the first set of buoys deployed in the North Central Pacific Ocean, and it is also the easternmost buoy deployed in the Pacific Ocean. The complex and harsh sea conditions during the deployment of the buoy posed a serious challenge to the buoy deployment. Under the command of the Chief Scientist and the ship's captain, the ship's crew made concerted efforts and coped with the situation calmly, and successfully completed the deployment of China's first set of deep-sea integrated observation buoys in the central and north Pacific Ocean.
When the last anchor chain of the buoy was lowered into the water, all the faces showed gratified smiles, applause and cheers rang out, the sun shone brightly over the waters of the central and north Pacific Ocean, and the buoy that had just been deployed shone brightly under the sunlight.
The role and significance of the Pacific Ocean buoys:
1. The buoy is the first set of buoys deployed in the North and Central Pacific Ocean, and it is also the most "eastern" buoy deployed in the Pacific Ocean. The buoy can not only observe air temperature, air pressure, wind speed, wind direction, relative humidity, waves, currents and other conventional hydrometeorological elements, but also through the inductive coupling transmission technology can be a real-time observation of the ocean's upper layer of seawater temperature, salinity and depth and other data.
2. The buoy is also the first to be installed with a sea gas flux observation system and a chemical element observation system. The on-site data it collects can be transmitted back to the domestic receiving center in real time via satellite.
3. Through the long-term continuous observation of heat flux, water vapor flux, momentum flux and other meteorological elements at the sea-air interface, the buoy helps to study the sea-air coupling processes and mechanisms such as the generation of typhoons and the central-type El Ni?o affecting China. Long-term observations of seawater temperature, salinity, and currents at different depths can provide real-time and long-term high-resolution oceanographic observations for in-depth studies of ocean circulation, mesoscale processes, eddy-current interactions, and ocean dynamics such as wave propagation characteristics and variability mechanisms in the ocean.
4. The successful deployment of the buoy fills the gap of real-time monitoring of marine environmental parameters in the North Central Pacific Ocean, and provides a solid data foundation for responding to global climate change and forecasting the marine environment.
