Tel Aviv University's "Earth Binoculars" see our planet through an astral lens One small step for mankind is now a leap for averting natural and man-made disasters on earth. New Tel Aviv University technology combines sophisticated sensors in orbit with sensors on the ground and in the air to create a "Hyperspectral Remote Sensor" (HRS).  It can give advance warnings about water contamination after a forest fire, alert authorities of a pollution spill long before a red flag is raised on...

U.S. satellite measurements show Arctic sea ice extent in 2009 "“ the area of the Arctic Ocean covered by floating ice "“ was the third lowest since satellite measurements were first made in 1979. The ice area at minimum was an increase from the past two years, but still well below the average for the past 30 years. Arctic sea ice reached its minimum extent around September 12. According to scientists affiliated with the National Snow and Ice Data Center (NSIDC), sea ice coverage...

Remains On Downward Trend Despite a slight recovery in summer Arctic sea ice in 2009 from record-setting low years in 2007 and 2008, the sea ice extent remains significantly below previous years and remains on a trend leading toward ice-free Arctic summers, according to the University of Colorado at Boulder's National Snow and Ice Data Center. According to the CU-Boulder center, the 2009 minimum sea ice extent was the third lowest since satellite record-keeping began in 1979. The past five...

Machine-mounted sensors, being developed through CSIRO Minerals Down Under Flagship, could help locate ore deposits, characterize the mining environment, and differentiate ore grades. Scientists are working on a new range of materials characterization analyzers and techniques that could help unlock the value contained in Australia's mineral deposits and improve processing performance, according to the October issue of Process. Machine-mounted sensors, being developed through CSIRO Minerals...

This summer's melt of Arctic sea ice might not have been quite as bad as the past two years, but satellite images reveal that it has now had the third biggest melt in 30 years, according to U.S. government scientists. The announcement was made on Thursday by the National Snow and Ice Data Center, which reported that the Arctic sea ice pack had reached its yearly minimum just last Saturday. It will not begin to grow again until fall begins. As of last Saturday, the sea ice only covered...

Arctic and Antarctic research teams pulled back to warmer climates when the International Polar Year wrapped last March. But the call has gone out for a return to the poles for a more focused investigation into the effects of global warming. Leading the charge back to the Canadian Arctic is David Hik, a University of Alberta biology professor and a lead researcher with IPY. "IPY gave us a great snapshot of the state of the planet's polar regions," said Hik. "But in the Arctic we made many...

U.S. scientists using satellite data and records from cold war submarine missions have found Arctic Ocean ice thickness has declined 53 percent since 1980. This summer, a group of U.S. and Canadian scientists and students set out from Resolute Bay, Canada, to check the Arctic Ocean ice. One of the scientists was Ron Kwok of NASA's Jet Propulsion Laboratory. Kwok, the space agency said, has long provided checkups on the health of arctic sea ice -- the frozen sea water floating within the...

This summer, a group of scientists and students "” as well as a Canadian senator, a writer, and a filmmaker "” set out from Resolute Bay, Canada, on the icebreaker Louis S. St-Laurent. They were headed through the Northwest Passage, but instead of opening shipping lanes in the ice, they had gathered to open up new lines of thinking on Arctic science.Among the participants in the shipboard workshop (hosted by Fisheries and Oceans Canada) was Ron Kwok of NASA's Jet Propulsion...

Hundreds of images derived from classified data that could be used to better understand rapid loss and transformation of Arctic sea ice should be immediately released and disseminated to the scientific research community, says a new report from the National Research Council.  The committee that wrote the report emphasized that these Arctic images show detailed melting and freezing processes and also provide information at scales, locations, and time periods that are important for...

U.S. scientists have used a supercomputer to calculate the iron isotope distribution in Earth's mantle that occurred 4.5 billion years ago. University of California-Davis geochemists said they simulated the conditions that would have existed when the Earth crystallized from an ocean of magma to its solid form, producing the first picture of how different isotopes of iron were initially distributed in the solid Earth. The scientists said their research could result in a wave of investigations...

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...

Earth science (or geoscience) is the science of the planet Earth. Earth science can be broken down into four major disciplines, which are: geography, geology, geophysics, and geodesy. These disciplines use physics, chemistry, biology, chronology and mathematics to arrive to a greater understanding of the principal areas of the Earth system. Since Earth is the only known life-bearing planet, Earth science is solely dedicated to the geophysical makeup of our own planet. One discipline,...

  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
