Su Jilan (21), an academician of the China Academy of Sciences and a researcher at the Second Institute of Oceanography of the State Oceanic Administration, made it clear that China should actively participate in the Argo project when discussing whether China will participate. He pointed out:
(1) What we are worried about is nothing more than the South China Sea issue, but the military of other countries has regularly obtained a large amount of various data in the South China Sea.
(2) whether we participate in the Argo plan or not, non-military organizations (scientific circles or observation operational systems) in countries around the South China Sea or other countries need to obtain the consent of all countries concerned (including China, Vietnam, the Philippines, etc.) if they want to deploy Argo profile buoys in the South China Sea, just like the international ocean drilling plan did when drilling holes in the South China Sea.
(3) Among the Argo profile buoys deployed by other countries' scientific research projects in the future, the Argo profile buoys that are most likely to "drift with the current" into the South China Sea should be deployed in the sea area outside the South China Sea by scientific research projects of South Korea, Japan and Australia, and the proportion of them entering the South China Sea will not be very high compared with the number of them deployed.
(4) The Argo plan is being perfected. If we actively participate in this plan, we can ensure that our opinions can be reflected in its specifications.
(5) Actively participating in the Argo program can provide opportunities for Chinese marine workers to fully participate in international exchanges and cooperation, and can rapidly improve the level of marine scientific research in China.
the principle of p>Argo's global ocean observation network construction follows the international practice, that is, * * * participation and information * * * sharing. In 1994, the first international tropical atmospheric ocean observation network (with 69 anchored ATLAS buoys) was built in the tropical Pacific Ocean. At that time, the mainland of China did not participate in the deployment of long-term observation buoys, so the real-time observation data released by the observation network could not be obtained in time, which made Chinese oceanographers lose an opportunity to deeply understand and understand the El Nino and La Nina phenomena in the tropical Pacific Ocean and how ENSO affected the climate in Chinese mainland. The Argo global ocean observation network, which will be built in the next three years, is obviously superior to the TAO observation network in terms of the number of observation buoys, the observation coverage area, and the representativeness and application value of observation data, and its observation data has immeasurable scientific value.
several large-scale investigation and research projects in China, such as the formation mechanism and prediction of major climate disasters in China (project 973), the formation and variation mechanism of China offshore circulation, numerical prediction method and its influence on circulation (project 973), the Indian Ocean-Pacific warm pool and its current system and air-sea interaction (project 973), all require the collection of the northwest Pacific and Indian Ocean waters, and even the entire Pacific Ocean.
The United States, Britain, Japan, Australia and other countries have set up special institutions to collect Argo buoy data, and made detailed plans and timetables to study the assimilation methods of Argo buoy data. Building a high-precision grid point database after data assimilation; And further improve the forecasting ability of ocean and short-term climate prediction model by using the assimilated Argo data. For example, National Environmental Forecasting Center (NCEP), Hadley Climate Center in Britain and Australian Meteorological Bureau (BMRC) have put Argo assimilation data into operational forecasting trial operation. Although there are still some problems, they have shown good development prospects. Up to now, China has not carried out this work. Western developed countries have already started ahead of us in the variational assimilation processing of Argo buoy data and the use of it to improve the forecasting ability of long-term weather forecast and short-term climate forecast model. China must carry out research work in this field as soon as possible in order to effectively improve the simulation and prediction ability of numerical models, which is of great significance to China's social and economic development.
in addition, because Argo buoy can drift with the sea water flow for a long time under water and work continuously, it is convenient to obtain a large number of marine environmental elements along the drift, which will also pose a certain threat to the rights and interests of coastal countries. From this point of view, China also urgently needs to master and apply this technology in order to serve the defense of national rights and interests. China plans to put 1 ~ 15 Argo buoys in 22 ~ 25 to build a local ocean observation network. In the future, 2 ~ 3 buoys will be put in every year to maintain the normal operation of the local observation network.
the overall goal of China's ARGO project is to build an ocean observation network (with 1 ~ 15 Argo profile buoys) in China's new generation of ocean real-time observation system (Argo) by introducing a new generation of international advanced floating ocean observation buoys (namely Argo profile buoys) and deploying them in the northwest Pacific Ocean adjacent to China (a few buoys will be deployed in the southern ocean and Indian Ocean as appropriate), so that China will become one of the international Argo projects. At the same time, it can enjoy the data of 3, ARGO buoys in the global ocean, enrich the data sources of related research projects undertaken by China's marine and meteorological circles, and provide strong technical support for the construction of the offshore observation network of the system, that is, through the construction of the ocean observation network, to understand and master the performance and characteristics of this high-tech ocean observation technology, and take the road of technology introduction, digestion and absorption and self-development, so that the maintenance of the future ocean observation network will be replaced by domestic Argo buoys. The offshore observation network is completely composed of Argo buoys made in China, and finally a self-contained real-time ocean observation network is built in China, which provides real-time observation data and products for China's marine research, marine development, marine management and maritime military activities. China officially decided to join the international Argo program in 21. The start-up fund of China Argo Project is funded by the Ministry of Science and Technology and implemented by the State Oceanic Administration. The China Meteorological Bureau, China Academy of Sciences and other departments and affiliated research institutions will participate in this work.
the ocean observation network will be arranged in the northwest Pacific Ocean connecting points N, 13 E to 15°N, 125 E to 23°N, 125 E to 3 N, 13 E to 3 N, 145 E to N, 145°E 6, according to the international ARGO. About 5 other ARGO buoys, depending on the progress of the test, may be put into the ocean and the southern ocean. ARGO buoys are deployed on sea and air observation platforms such as professional survey ships, volunteer ships and sea surveillance aircraft.
at the end of p>21, the Ministry of science and technology has allocated special funds, and the First and Second Institute of Oceanography of the State Oceanic Administration introduced one PROVOR buoy and two APEX buoys from Metocean Company of Canada and Webb Company of the United States respectively. The former was deployed in the Indian Ocean in March 22; The latter is waiting to be released. The two APEX buoys are deployed in the northwest Pacific Ocean as planned. According to the plan, 8-1 more will be deployed in the Pacific Northwest before the end of 22.
With the support of the Institute of Marine Technology of the State Oceanic Administration, the "Research on Key Technologies of Self-floating Neutral Drifting Buoy" was started in March, 2. After just one year's struggle, two key technologies of Argo Buoy's automatic ups and downs and depth control were initially mastered. Soon, with the support of the "Tenth Five-Year Plan" 863 project, the Institute continued to develop the "self-sustaining circular profile detection drifting buoy". It is planned to complete several Argo buoy engineering prototypes that can be actually used in the ocean with a water depth of 2m before 24. In June, 22, the first prototype of "self-sustaining circulating profile detection drifting buoy" developed by the institute itself has carried out the first on-site observation test at sea.
The buoys needed for the construction of ocean local observation network in China's Argo plan will be mainly imported from abroad. China also plans to import major components from abroad and assemble such buoys at home, so as to reduce the cost of buoys and reduce the damage and technical failure of instruments caused by long-distance transportation.
with the launch of the first batch of Argo buoys, China is preparing to build its own Argo data center to meet the demand for receiving, processing and distributing Argo buoy data. At the same time, the observation data and information of Argo buoy in China will be sent in time through GTS and INTERNET, so as to share Argo buoy data in the global ocean with other countries. The State Oceanic Administration has also established an Argo information website in China, which has been put into trial operation.
The State Oceanic Administration has entrusted its subordinate oceanographic research institutions, namely the Second Institute of Oceanography (Hangzhou) and the State Oceanic Administration's Key Laboratory of Ocean Dynamic Processes and Satellite Oceanography (Hangzhou), to host the 5th International Argo Scientific Group Meeting (Hangzhou, March, 23), in order to show that China attaches importance to and supports the international Argo program. This proposal has been responded by all the delegates at the 4th International Argo Scientific Group Meeting held in Hobart, Australia in March, 22 and adopted by the International Argo Scientific Group. China hopes that by hosting the Fifth International Argo Scientific Group Meeting, it will have more opportunities to get guidance and help from the International Argo Scientific Group and the organizations and implementers of Argo plans in various countries, strengthen and close international exchanges and cooperation, speed up the implementation process of the international Argo plan, and make contributions to the smooth implementation of the international Argo plan and achieve the expected goals. On September 26-27, 1999, at the 14th meeting of the Sino-US Joint Working Group on Marine and Fishery Science and Technology Cooperation, China and the United States adopted a new cooperation project in the field of "the role of oceans in global climate change", namely "Ocean Observation in the Western Pacific and Indian Ocean (Argo Plan)". China began to follow the progress of the international Argo plan.
from March p>·2 to March 21, the Institute of Marine Technology of the State Oceanic Administration, with the support of the "Ninth Five-Year Plan" 863 rolling development project, carried out the "Research on Key Technologies of Self-floating Neutral Drifting Buoy", and initially mastered two key technologies of Argo Buoy, namely, automatic floating and depth control.
From May 15 to 26, 2, a delegation from China, headed by Academician Chao Jiping, went to the United States for a 1-day marine technical investigation, and gained a deeper understanding of the progress and implementation of the Argo plan in the United States. After returning to China, he submitted the "Investigation Report on the Construction Progress of Argo Global Ocean Observing Network" to the Ministry of Science and Technology, the State Oceanic Administration and other national government departments, and suggested that the relevant state departments invest funds to study and consider joining Argo Global Ocean Observing Network as soon as possible, so as to have the right to enjoy Argo data.
