A dark rock will quickly absorb and not reflect much light energy where as ice will reflect a lot of light and not absorb very much. Man made materials versus natural materials have different absorptions and reflections as well. Ice is naturally reflective along with certain types of clouds. Rock and other dark materials absorb more energy than lighter materials. Rough materials absorb more energy than smooth materials. This lesson has students collect data on differing materials pdboyer Thu, 02 Jul 2009 19:08:37 GMT http://geologyonline.museum.state.il.us/geogallery The ISM Geology Online is a database of detailed information and high-quality photographs for 101 selected objects from the Museum's geology and anthropology collections. pdboyer Wed, 11 Feb 2009 03:53:37 GMT http://www.nasa.gov/mission_pages/ostm/news/ostm-20080730.html Less than a month after launch, the NASA-French space agency Ocean Surface Topography Mission (OSTM)/Jason 2 oceanography satellite has produced its first complete maps of global ocean surface topography, surface wave height and wind speed. The new data will help scientists monitor changes in global sea level and the distribution of heat in the ocean. This information is used to monitor climate change and ocean circulation, and to enable more accurate weather, ocean and climate forecasts. The data reveal patterns of sea level anomalies, which are used by scientists to calculate the speed and direction of ocean surface currents. pdboyer Tue, 14 Jul 2009 13:11:27 GMT http://www.nasa.gov/externalflash/nasacity/index2.htm REALLY cool interactive from NASA that shows relevance of space program in everyday life. Very interactive and high tech! Interactive Whiteboard pdboyer Wed, 22 Jul 2009 17:21:34 GMT http://www.nasa.gov/topics/earth/features/greenland_flights.html Imagine a piece of ice 1,000 miles long, 400 miles wide, and 2 miles thick in the center. That's the Greenland ice sheet. But that island-sized piece of ice is melting, so NASA researchers are flying to the Arctic this week to learn more about the nature of those changes. pdboyer Tue, 14 Jul 2009 12:02:20 GMT http://rst.gsfc.nasa.gov/Sect16/Sect16_1.html This Section surveys one general but vital idea and then addresses how the Earth Sciences community is responding to implementing the outgrowths of this idea. A new field seems to have emerged in the last 20 years. It goes by the imposing name: Earth System(s) Science. But, its ingredients have been around for a long time (some of the components make up the contents of Physical Geography textbooks). The basic notion is this: instead of treating such fields as meteorology, oceanography, botany, ecology, living creatures, aspects of geology, etc. as discrete, self-contained knowledge bases, recognize that they are all part of the same system that controls the Earth, and hence all pointed towards a central common theme, and then cross-link (integrate) the n... pdboyer Wed, 24 Jun 2009 02:35:32 GMT http://rst.gsfc.nasa.gov/Front/tofc.html pdboyer Wed, 24 Jun 2009 02:39:11 GMT http://svs.gsfc.nasa.gov/vis/a000000/a000500/a000584/index.html NASA Scientific Visualization Studio - Greenland Ice Sheet changes.
