The Yucca Mountain crest in Nevada, USA has been proposed as a permanent site for high level radioactive waste. But a new study, already published as an article in press by Elsevier's journal Geomorphology and recently included in the Research Highlights of Nature, shows that there may be erosion of the crest. Kurt Stwe of the University of Graz, Austria, together with his colleagues, used a simple numerical landscape evolution model to explore the rate of erosional decay of the Yucca...

Autonomous vehicle developed by the University of Washington is an element of Arctic Observing Network, an International Polar Year research priority An intelligent, ocean-going glider has spent six months on a record-breaking deployment to sample the icy waters off western Greenland. The samples will contribute to the longest continuous measurement of Arctic currents that help to drive ocean circulation and regulate global seawater temperatures. The 49-kilogram (110-pound) seaglider,...

A newly initiated campaign marks an important step in preparing for how data from the Sentinel-1 European Radar Observatory will be used for applications such as land-cover mapping and crop management. Sentinel-1 is the first of the five missions that ESA is developing for the GMES initiative. Sentinel-1 is a constellation of two C-band radar satellites that will provide continuous all-weather, day and night imagery for use in a range of diverse services "“ from marine and land...

WASHINGTON, April 6 /PRNewswire-USNewswire/ -- The latest Arctic sea ice data from NASA and the National Snow and Ice Data Center show that the decade-long trend of shrinking sea ice cover is continuing. New evidence from satellite observations also shows that the ice cap is thinning as well. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) Arctic sea ice works like an air conditioner for the global climate system. Ice naturally cools air and water masses, plays a key role in...

NASA and the National Snow and Ice Data Center say that the decade-long trend of shrinking sea ice cover in the Arctic is continuing and new evidence suggests that the ice cap is thinning as well. Arctic sea ice naturally cools air and water masses and plays an important role in ocean circulation as well as reflecting solar radiation back into space. However, Arctic sea ice has been declining at a staggering rate in recent years. Satellite monitoring of Arctic sea ice showed that this winter...

Arctic reindeer herders are facing the challenges of adapting to climate change as a warmer Arctic climate makes it harder for herds to find food and navigate. To help them adapt, the ESA-backed Polar View initiative is providing the herders with satellite-based snow maps. "Snow is of paramount importance for reindeer herding because its quality determines whether reindeer are able to access the pastures that lie beneath it for much of the year," said Anders Oskal, the Director of the...

An efficient network of specialists, data and tools to explore and safeguard Antarctica formed as legacy of IPY The International Polar Year (IPY) concluded in March 2009 with a tangible legacy in the form of a network of databases on marine biodiversity that will serve as clearinghouse for all biodiversity-related data gathered since the very first Antarctic research expeditions. The network gathers data describing the species themselves as well as information about their collection history,...

NASA says it has produced a unique movie about Earth's changing ice and snow cover to be shown at U.S. science centers and museums. The National Aeronautics and Space Administration says the Goddard Space Flight Center in Greenbelt, Md., produced the film for its Science on a Sphere projection system -- a fully spherical video technology. The six-foot spheres are installed in more than 30 locations around the world. The space agency said Frozen uses satellite data to investigate all parts of...

NASA has created a unique "spherical" movie about Earth's changing ice and snow cover as captured by NASA spacecraft. "Frozen," a 12-minute, narrated film, premieres at science centers and museums March 27. NASA's Goddard Space Flight Center in Greenbelt, Md., produced the film for the "Science on a Sphere" projection system, a fully spherical video technology developed by the National Oceanic and Atmospheric Administration. The six-foot spheres are installed in more than 30 locations around...

Glacier ice appears to be melting in the western portion of Antarctica and not only on the Antarctic Peninsula, scientists reported on Wednesday in conclusion to the 2007-2008 International Polar Year. The World Meteorological Organization (WMO) alongside the International Council for Science (ICSU) released the "State of Polar Research" report today. The IPY took into account the work of more than 160 projects from researchers in more than 60 countries and received funding of about $1.2...

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.'
