Since the end of last month, China’s first submarine circular ecological monitoring and observation network has been placed in Penglai, Shandong Province. The project leader and researcher of the National Ocean Technology Center, Luo Xingye, has an additional concern, fearing that the two-kilometer submarine optical cable and hundreds of dollars will be worth hundreds of kilometers. Ten thousand underwater observation equipment was destroyed by fishing boats.
Luo continued to be a singer.
On the coastline of 18,000 km, more than 200 ocean observatories (nets) have formed our offshore ocean observation capabilities. However, marine observation facilities are often deployed in the busiest areas of the sea. On the busy sea 'night market' , equipment is often destroyed.
Engaged in marine surveys and observations for more than 20 years. In the project of the Institute of Ocean Research of the Chinese Academy of Sciences, a quarter of the buoys, the submarine marks were destroyed, and most of them were concentrated in the offshore.
'There is no comprehensive statistics on the damage situation of the national ocean observation facilities, but such proportions are representative. The recovery rate of foreign facilities is only 60%-70%. ' Yu Fei said, how to protect marine observation facilities is facing at home and abroad. Common topic.
Millions worth of equipment disappeared in the sea for three days.
Ocean buoy, a modern ocean observation facility that is anchored at a designated location to collect marine environmental data and enable automatic data collection, automatic labeling and automatic transmission. These basic observations are oceans in our country. Management, marine development, the foundation of marine scientific research.
During the '10th Five-Year Plan' period, the National Marine Technology Center deployed a seabed-based observation system in the Qingdao sea area. Because the price is as high as two or three million yuan, the project team sent someone to stare at the 'tip'. Unfortunately, it happened, a meal. Work, this equipment that only runs for three days at sea is gone.
In the past few years, fishermen deliberately destroyed buoys in order to obtain batteries. In the past five years, with the improvement of the quality of fishermen, this situation is not common, but the proportion of unintentional damage is still high. Instrumentation Liu Shizhen, director of the Institute's buoy room, said.
Affects the efficiency and continuity of data collection
The canola from the shoal of northern Jiangsu has turned the Qingdao beach in Shandong into a 'grassland' for 12 consecutive years.
In recent years, relevant departments have used satellites, land-based patrols, ships, etc. to carry out monitoring of the green tide of the Yellow Sea, and to carry out numerical simulation drift prediction. However, it seems that in the three months before the disaster, fixed-point continuous observations were obtained. First-hand information is the most important.
Regrettably, in the hundreds of kilometers journey from the north of the canola to the Weihai of Shandong, there are only a few buoys in the offshore to monitor the marine environmental parameters, and there is still a large error in the forecast of the canola scale and migration path.
'The buoy is less, directly related to fear of being destroyed.' Yu Fei said.
After being repeatedly stolen by two buoys, since 2005, the Yantai Marine Environmental Monitoring Center Station (hereinafter referred to as the Central Station) of the State Oceanic Administration has not dared to deploy buoys in Zhifu Island and return to the original visual method. Affects the efficiency and continuity of data collection, data integrity.
Ji Ling, the deputy stationmaster of the central station, told the reporter that in the once-in-a-half-year, once-in-a-century marine engineering demonstration, observing historical data is an important basis. 'If the data in this area is missing, it can only be derived from data from distant sites. Data that is not directly obtained is accurate and reliable.'
If the facility is damaged or lost, it will lead to data erratic, affecting the forecasting service and disaster prevention and mitigation work. If it encounters disaster weather, it may cause serious economic loss.
No need to raise awareness of facility protection
Yu Fei said that the researchers are doing some work.
One of the solutions is to enlarge the buoy as much as possible. These buoys tend to cost millions, although it is inevitable that there is a suspicion of 'killing the chicken with a knife', but at least the fishermen will not act rashly. For example, the buoy uses non-standard parts, let the destroyer Can't easily get it. The drawback is that it increases the cost of each buoy and does not have the ability to put more buoys.
They are also strengthening cooperation with the local maritime sector, such as the inclusion of buoy points in the navigation of the navigation mark, and the ship's accountability.
A few years ago, the Shandong Academy of Sciences instrument meter The 10-meter large buoy worth nearly 4 million yuan was damaged by the Institute to the Zhejiang Meteorological Bureau. The first time to contact the maritime department, the latter through the shipborne AIS, the object of the accident is locked into a 10,000-ton container ship. , eventually won more than 1.6 million yuan.
Destruction of marine facilities has already set a precedent for punishment. Such cases have played a very vigilant role. It seems that the most important thing is to increase the propaganda of governments at all levels in coastal areas, especially the promotion of regulations on the management of ocean observation and forecasting. Fishermen protect the awareness of ocean observation facilities and understand the importance of ocean monitoring.
