JOHANNESBURG, March 8 (Xinhua) -- In order to combat piracy and to improve maritime safety, South African authorities have begun using a sophisticated navigation satellite system, it was announced on Tuesday.Piracy, especially by Somalis, has been increasing along Africa east coast in recent years. The South African Press Association (SAPA) reported on Tuesday that Karl Otto, head of the South African Maritime Safety Authority (SAMSA) announced the surveillance tool at a conference in Durban.Called Long Range Identification and Tracking (LRIT), the system monitors and tracks vessels in waters south of the equator.Otto said the introduction of the LRIT followed concerns over the safety of seafarers, the safety standards of ships within South African waters.Otto said there were high levels of cargo at risk, such as fuels and oils.He said reasons for installing the system included the number of shipwrecks along the South African coast, and the threat of pollution of the marine environment by ships."It also serves as a mechanism to prevent piracy."Otto said the satellite system has the capacity to identify and track vessels up to 1,000 nautical miles (1,850 km) from the South African coastline as well as South African-flagged vessels anywhere in the world."This is a revolutionary development in the security of our seas," he said.SAMSA was determined to protect South Africa's seafarers, its coastline and the marine environment, Otto said.

BEIJING, March 6 (Xinhua) -- China aims to "basically eradicate poverty" by 2020 while greatly raise its poverty line, in order to help more people in need, Chinese Premier Wen Jiabao said here Sunday.The State Council is drafting a new ten-year poverty-reduction plan (2011-2020), in which the current poverty line of 1,196 yuan per year (about 0.5 U.S. dollars a day) will be greatly raised, Wen told a panel meeting of the ongoing session of the National People's Congress (NPC).The nation will intensify its poverty alleviation efforts through aids and development, focusing on large areas of destitute population, he said to a group of NPC deputies from Gansu, one of the poorest regions in China.According to the United Nations' standard of one dollar per person each day, China still has 150 million people under the poverty line.Wen said lack of water was the bottleneck for Gansu's social-economic development, urging the province to expand the use of water conservancy technology.Wen also urged the province to coordinate economic development with environmental protection, and reverse environmental degradation in Dunhuang, a historical city with world cultural heritage threatened by decertification.

BEIJING, Jan. 26 (Xinhua) -- China's civil affairs ministers visited survivors of last year's 7.1-magnitude Yushu earthquake and Zhouqu mudslide prior to China's lunar new year.Dou Yupei, vice minister of Civil Affairs, led a team to Yushu in northwest China's Qinghai Province to visit quake survivors and local cadres beginning on Sunday.Dou told Xinhua that quake survivors in Yushu now had access to food, clothing, safe drinking water, shelters and medical services, and the reconstruction of quake-damaged houses was well underway.Further, the ministry has distributed 45,000 cotton-padded tents to Yushu to house survivors during the extremely cold winter on the Qinghai-Tibet plateau.So far, 160,000 tents have been set up to assure that all survivors have a roof overhead, according to the ministry's statement issued Wednesday.Yushu was jolted by a 7.1-magnitude earthquake on April 14, leaving 2,200 people dead and 220,000 local residents affected.Another vice minister, Sun Shaocheng, visited survivors from a massive mudslide that left 1,700 people dead or missing in Zhouqu, Gansu province.To provide warm shelters to survivors, the Zhouqu county government invested three million yuan (455,000 U.S. Dollars) in renovating vacant school buildings or installing facilities in newly-built apartments.All survivors who previously had taken shelter in make-shift tents were relocated to these buildings before Oct. 13, according to the ministry's statement.

XICHANG, Sichuan, April 10 (Xinhua) -- China early Sunday morning successfully launched its eighth orbiter which will form part of its indigenous satellite-navigation and -positioning network.A Long March-3A carrier rocket carrying the "Beidou," or Compass, navigation satellite took off at 4:47 a.m. Sunday from the Xichang Satellite Launch Center in southwest China's Sichuan Province.It will join seven other satellites already in orbit to form a network which will eventually consist of more than 30 satellites.The launching of the satellite marks the establishment of a basic system for the navigation and positioning network, said an unidentified spokesperson for the Xichang Satellite Launch Center.China will launch more satellites within the coming two years to finish a regional network to provide navigation services with high precision and credibility for industries and sectors such as mapping, fishery, transportation, meteorology and telecommunication, in the Asia-Pacific regions, the spokesperson said.The network is scheduled to be able to provide global services by 2020.

WASHINGTON, May 17 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) announced Tuesday that the international Aquarius/SAC-D observatory will be launched on June 9, to study interactions between ocean circulation, the water cycle and climate by measuring ocean surface salinity.Engineers at Vandenberg Air Force Base in California are performing final tests before mating the satellite to its Delta II rocket. The mission is a collaboration between NASA and Argentina' s space agency, with participation from Brazil, Canada, France and Italy.In addition to Aquarius, the primary instrument, the observatory carries seven other instruments that will collect environmental data for a wide range of applications, including studies of natural hazards, air quality, land processes and epidemiology.The mission will make NASA's first space observations of the concentration of dissolved salt at the ocean surface. Aquarius' observations will reveal how salinity variations influence ocean circulation, trace the path of freshwater around our planet, and help drive Earth's climate. The ocean surface constantly exchanges water and heat with Earth's atmosphere. Approximately 80 percent of the global water cycle that moves freshwater from the ocean to the atmosphere to the land and back to the ocean happens over the ocean.Salinity plays a key role in these exchanges. By tracking changes in ocean surface salinity, Aquarius will monitor variations in the water cycle caused by evaporation and precipitation over the ocean, river runoff, the freezing and melting of sea ice. Salinity also makes seawater denser, causing it to sink, where it becomes part of deep, interconnected ocean currents. This deep ocean "conveyor belt" moves water masses and heat from the tropics to the polar regions, helping to regulate Earth's climate."Salinity is the glue that bonds two major components of Earth' s complex climate system: ocean circulation and the global water cycle," said Aquarius Principal Investigator Gary Lagerloef of Earth & Space Research in Seattle in a statement. "Aquarius will map global variations in salinity in unprecedented detail, leading to new discoveries that will improve our ability to predict future climate."Aquarius will measure salinity by sensing microwave emissions from the water's surface with a radiometer instrument. These emissions can be used to indicate the saltiness of the surface water, after accounting for other environmental factors. Salinity levels in the open ocean vary by only about five parts per thousand, and small changes are important. Aquarius uses advanced technologies to detect changes in salinity as small as about two parts per 10,000, equivalent to a pinch (about one-eighth of a teaspoon) of salt in a gallon of water.Aquarius will map the entire open ocean every seven days for at least three years from 408 miles (657 kilometers) above Earth. Its measurements will produce monthly estimates of ocean surface salinity with a spatial resolution of 93 miles (150 kilometers). The data will reveal how salinity changes over time and from one part of the ocean to another.
