Beijing time, January 26 news, U.S. scientists said the world's largest super volcano - Yellowstone National Park underground super volcano fear approaching eruption, and once the eruption, the U.S. two-thirds of the country may be buried by volcanic ash.
It is reported that the super volcano under Yellowstone National Park has been rising at a record rate since 2004. According to scientists, once it erupts, it will be a thousand times more destructive than Mount St. Helens was when it erupted in 1980. Lava would be spewed into the sky, ash clouds destroying plants would erupt, and places 1,000 miles (1,600 kilometers) away would be covered in ash up to 10 feet (3 meters) thick. Two-thirds of the United States would be uninhabitable, and the eruption would also release toxic gases into the air, grounding thousands of flights and displacing millions of people.
Yellowstone National Park's underground super volcano is the world's largest, and if it erupts as scientists predict, it will be its first eruption in 600,000 years. The volcano has erupted massively three times in the past 2.1 million years, and researchers say it is feared that it will erupt again soon. According to researchers, Yellowstone National Park's underground super volcano has been rising at a record pace since 2004 -- in the past three years alone, its floor has risen at a rate of 3 inches (7.6 centimeters) per year, the fastest rate since records began in 1923.
However, plagued by a lack of data, they have not issued a comprehensive warning and cannot make an accurate prediction of when the next disaster will strike. Once it finally erupts, its destructive power will dwarf the eruption of Iceland's Eyjafjallaj?kulla ice cap volcano. The Eyjafjallaj?kulla ice cap volcano erupted in April 2010, sending ash billowing across the sky and paralyzing air traffic around the world for days.
China's Yellow and Bohai Sea sea ice 35,800 square kilometers, Bohai Sea 40% covered
China News Agency, Beijing, January 24 (Reporter Ruan Yulin) The National Marine Environment Forecasting Center released the latest news, said on the 24th, China's Yellow and Bohai Sea sea ice area has reached 35,793,000 square kilometers. Bohai Sea ice floe area of 31,600 square kilometers, 40% of the Bohai Sea area covered by sea ice. The State Oceanic Administration Marine Forecasting Office issued a yellow alert for sea ice in Laizhou Bay and a blue alert for sea ice in Liaodong Bay on the 24th.
According to satellite remote sensing monitoring on the 24th, the sea ice area of China's Yellow Sea and Bohai Sea has reached 35,793,000 square kilometers. The maximum outer edge of sea ice in Laizhou Bay of the Bohai Sea is 37 nautical miles, with a distribution area of 6,188 square kilometers, accounting for 69% of the area of the sea, reaching the standard of yellow alert for sea ice, and the National Marine Forecasting Station issued a yellow alert for sea ice in Laizhou Bay. The maximum outer edge line of sea ice in Liaodong Bay is 72 nautical miles, with a distribution area of 17,436 square kilometers, accounting for 57% of the total area of the sea, a slight increase from the previous day; the maximum outer edge line of sea ice in Bohai Bay is 22 nautical miles, with a distribution area of 8,004 square kilometers, accounting for 54% of the total area of the sea; the maximum outer edge line of sea ice in the northern Yellow Sea is 13 nautical miles, with a distribution area of 4,165 square kilometers, a slight increase from the previous day .

Meteorological experts say global warming to extreme weather or 20 years
Chinese New Network, January 18, according to Taiwan's "United Evening News" 18 reported, meteorological experts said 2010 is "extreme weather year", extreme phenomena continue to the new year, Australia appeared in a century of heavy water, Brazilian mudslides, causing more than 670 people dead, Sri Lanka's mudslide, and the United States, the United States, the United States, the United States, the United States, the United States, the United States, the United States, the United States, and other countries. caused more than 670 people killed, Sri Lanka has 360,000 people because of the floods homeless, China, Japan, South Korea are the lowest temperature in decades.
This winter has seen a proliferation of extreme weather around the world. Experts say the unusual weather in the northern hemisphere stems from cold Arctic winds, while the southern hemisphere is mainly affected by the anti-saint baby phenomenon. Experts from the World Meteorological Organization have warned that with global warming, extreme weather, which used to be rare in the past century, could become a "once-in-20-years event".
Climate experts say the volume of the Arctic ice cap has decreased by 20 percent over the past 30 years due to warming. The lack of ice cover on the polar oceans means that the relatively warm air at the surface moves to colder altitudes, affecting the polar atmospheric circulation. Cold polar air masses continue to invade southward, dominating the climate of the Northern Hemisphere.
Not long ago, Europe's snow, is because of the Arctic cold air triggered by the snow and cold weather; the impact of the United States a few days ago, there are even Hawaii are snow "phenomenon", China should be four seasons like spring in Guizhou also appeared to be freezing rain. South Korea has seen the lowest temperature in 96 years, and the Han River is also frozen.
Australia's flooding was the result of the Anti-Santa Claus phenomenon, which lasted from mid-2010 to the present day, and the floods in Indonesia and Brazil were also the result of the Anti-Santa Claus.
2010 has already been the wettest and hottest year on record,*** with 18 countries experiencing the hottest temperatures on record. World Meteorological Organization expert Asrar said computer simulation studies show that with global warming, the future occurrence of extreme weather phenomena will be more frequent and more intense, affecting a wider area, for example, in the past 100 years will be only once a heat wave, will likely become a 20-year occurrence. By the end of the century, the extreme heat of the European summer of 2003 may no longer seem extraordinary.
Fujian strengthen marine ecological restoration, strict control of reclamation in the Bay
Fuzhou, China News Agency, January 6 (Reporter Sun Xianxun) marine province of Fujian this year, will focus on strengthening marine environmental protection of nearshore waters, the implementation of the near-shore marine ecological protection, restoration and construction, so that it presents a "blue sea and silver beaches, gulls and fish" of the beautiful scene. The newest addition to the list is the newest addition to the list, which is the newest addition to the list.
Fujian Provincial Ocean and Fisheries Department Director Liu Xiude said on the 6th, in order to build a clean sea, beautiful environment, "blue home", Fujian will further strengthen the environmental pollution remediation and marine ecological restoration efforts to increase the focus of the bay, estuaries and fisheries breeding areas of the marine environment comprehensive remediation, to take the embankment back to the sea and the interception of flow The measures include pollution control, mangrove expansion, pollutant recycling, adjusting the breeding density in the breeding area, promoting scientific baiting and medication, promoting ecological breeding mode, and strengthening the monitoring of pollutants entering the sea from land sources, so as to make a greater breakthrough in ecological environment protection of the near-shore sea areas.
The Fujian Provincial Government recently issued a document proposing to strive for more than 63 percent of the area of near-shore sea water quality to meet or better than the second class of water quality standards in 2012, and to increase to more than 65 percent in 2015.
Liu Xiu De said, in order to protect the near-shore marine environment, Fujian encourages and advocates the scientific use of the sea, the future strict control of land reclamation in the bay, guide to encourage the reclamation of land in the periphery of the bay; actively guide the coastal municipalities to carry out the regional planning work of the sea, to promote the intensive, economical use of the sea to reduce the environmental pollution of the bay, to protect the marine ecological environment; strict environmental impact assessment system for sea-related engineering and construction projects to prevent and reduce sea-related, coastal construction projects, to prevent and reduce the environmental impact assessment system for sea-related engineering and construction projects. Prevent and reduce sea-related, coastal engineering construction projects pollution damage to the marine environment.
He said Fujian will also further improve the emergency response mechanism for sudden pollution accidents and disasters at sea, improve the emergency response plan for marine disasters and sudden marine environmental pollution incidents, and improve the emergency response capability for sudden pollution incidents in marine and fishery waters; and promote the prevention and control of pollution in near-shore marine areas and the protection of marine ecosystems onshore and offshore, in accordance with the principle of "land and sea integration, and taking into account the river and the sea". In accordance with the principle of "integration of land and sea, river and sea", to promote the prevention and control of pollution in near-shore sea areas and land and watershed environmental protection linkage.
In recent years, Fujian has been actively building a strong marine economy, and the marine economy has continued to develop in a healthy and rapid manner, with the gross domestic product of the oceans ranking at the forefront of the mainland. However, with the rapid development of the coastal economy, Fujian near-shore marine ecological and environmental pressures continue to increase, mainly: the overall trend of pollution of the marine environment has not yet been effectively controlled, the local ecosystems of near-shore marine areas have been seriously damaged, the prevention and control of marine pollution and emergency response capacity is weak, and the construction of marine environmental protection infrastructure is relatively lagging behind.
Scientists searched for 170 meteorites in the Antarctic ice sheet
Beijing time, January 5 news, the U.S. space network reported, in the Antarctic ice sheet, a group of scientists are looking around the ground rocks. These people are meteorite scientists, and their work is part of the 2010-2011 Antarctic Meteorite Search Program (ANSMET).
One member of the expedition, updating her blog from the LaPaz ice sheet, described their current status as "very good".
"We've been camped out here on the ice sheet for two weeks now, and we've made a lot of progress," wrote Melissa Lane. She is from the Planetary Science Institute (PSI) in Tucson, Arizona, USA. "We found 170 meteorites in one ****, and the most interesting one from a petrological point of view is this latest discovery."
Lainey is a planetary geologist on the expedition, a group that also includes John Schutt, a field science guide and safety officer with 30 years of experience; Serena Aunon, an astronaut and physician from NASA's Johnson Space Center; and geologist Stephen Ballou ( Stephen Ballou), who is from Bilroyte College in Wisconsin.
The team arrived at La Paz on Dec. 16 on a Twin Otter, along with tents, cooking supplies and other necessities for the team. The next day, two other planes brought snowmobiles, allowing the eager scientists to begin their first meteorite search.
"The beauty of the place, and the experience of driving these novel vehicles across the vast, endless ice fields, excites everyone, Barao said. "Every one of us is overjoyed and very grateful to be here. But the truth is, our only purpose here is to work. And working here is going to be very difficult, with all the little things that are normally difficult. That includes getting dressed, eating, and even just getting out of the tent will be difficult."
But the team is still buoyed by the fact that they will be able to stay in Antarctica for another 25 days and have the opportunity to travel to Patuxent Ridge. "We can continue our passion for meteorite searching." Onon, a crew member from NASA, also documented their encounters on her blog.
"The 'Ski-Doos' snowmobile was our best companion. It was well-equipped and carried a survival kit to sustain four people, meteorite collection equipment, several liters of water, food, a medical kit, an Iridium phone, and a GPS location device." Onon said. "We meticulously checked the snowmobile engine in the morning in order to make sure it was performing well."
The Antarctic Meteorite Search Program has been funded by the National Science Foundation and NASA's Planetary Science Division since 1976.
Antarctica has had a steady stream of meteorite finds since its discovery. The first Antarctic meteorite was found in 1912 by an Australian expedition. So how do expeditioners collect meteorites?
First, they use the meteorite collecting kit they carry. The kit should include some of the following tools: a sterile bag for the meteorite, a numbered sign, tape to seal it, a notebook to record information about the meteorite, and scissors to cut things up.
The team must be very careful not to touch the meteorite, and shouldn't even let exhaled gas come into contact with it. Putting a meteorite under your nose when you have a cold or a runny nose is a definite no-no.
The meteorite should be sealed in a sterile bag as quickly as possible, so it is common practice to open the bag and hold the meteorite upside down. The meteorite should be measured, sometimes photographed, and its size and dimensions, color, and possible classification noted. An aluminum numbered nameplate is then placed in the bag and the bag is sealed. With any luck, the team's backpacks should be bulging with meteorites after a day of collecting.
The collected meteorites will be kept frozen and sent to the Antarctic Meteorite Isolation Laboratory at NASA's Johnson Space Center in Houston. Here, the meteorite samples will be carefully desiccated and sliced for distribution to research institutions for use.
Japan will build Okinotori Reef into a marine resources research base
China News Network, January 6, according to the Japanese **** the same news agency reported on the 6th, the Japanese government will start from the 2011 fiscal year in the "Okinotori Island" (China said the Okinotori Reef) construction of a series of facilities, will be built into a base for marine resources research. The Japanese government will spend 75 billion yen (about 6 billion yuan) in 6 years, to build 150-200 meters long pier for marine survey ships and other large ships to berth. In addition, the Japanese government plans to investigate the surrounding waters because of the possibility of rare metals and other resources.
Japan's move is aimed at preserving its sovereignty over the exploration and development of its exclusive economic zone (EEZ), which covers an area of about 400,000 square kilometers and has a 200-nautical-mile radius (370 kilometers) centered around Okinotori Reef, and at the same time counteracting China, which has been claiming that the island is "nothing more than a rocky reef," said the report. China has been claiming that the "island" is "nothing more than a rocky reef". The battle between China and Japan over maritime rights and interests will intensify.
Okinotori Reef is 4.5 kilometers long from east to west and 1.7 kilometers long from north to south. Only the tops of the northern and eastern islets (both about 1 meter) are exposed at high tide, and they are currently protected by a ring of concrete berms.
The new facility must be able to withstand harsh weather, as the Pacific Ocean's huge waves accelerate the deterioration of concrete buildings. The plan is to build a jetty on the outer side of Okinotori Reef and pave a road between it and the northern islets that can accommodate heavy machinery and other vehicles. Authorities will measure the seabed where ships dock after April and investigate conditions such as the strength and direction of waves.
The Japanese government passed a law in May last year, stipulating that both Okinotori Reef, which is located in the southernmost part of Japan, and Minami-Torishima, which is located in the easternmost part of the country (under the Tokyo metropolitan area), are placed under state management, and decided to build ports and other facilities.
