Earth Sciences (also referred to as Geosciences), which deals with basic issues surrounding our planet, plays a vital role in the area of energy and raw materials supply.
Earth Sciences comprises subjects such as geology, geography, geological informatics, paleontology, mineralogy, petrography, crystallography, geophysics, geodesy, glaciology, cartography, photogrammetry, meteorology and seismology, early-warning systems, earthquake research and polar research.
Awareness of the global warming effects of carbon dioxide (CO2) is relatively recent, but the greenhouse gas has been playing a critical role in warming our planet for billions of years, according to University of Maryland geologist Jay Kaufman and Virginia Polytechnic Institute geologist Shuhai Xiao.
Their results, which provide the best evidence to date of the age of the Calvin cycle—the photosynthetic cycle by which plants convert light energy and CO2 into cellular tissue—will be publishe
Three “Doppler On Wheels” (DOW) mobile radars developed partly at the National Center for Atmospheric Research (NCAR) are heading toward the mid-Atlantic coast to intercept the eye of Hurricane Isabel as the powerful storm hits land. Meanwhile, the nations next-generation weather model, developed at NCAR and other labs, is training its electronic “eyes” on a virtual Isabel at NCARs supercomputing center in Boulder. The DOWs will deploy at or near the coast in the direct path of t
Modern radiometric dating of the Siloam Tunnel in Jerusalem shows that it was excavated about 700 years before the Common Era, and can thus be safely attributed to the Judean King Hezekiah. This is the first time that a structure mentioned in the Bible (Kings II 20:20; Chronicles II 32:3, 4) has been radiometrically dated.
A report on the study of the Siloam Tunnel will be published on Sept. 11 in the scientific journal Nature. The research was conducted by Dr. Amos Frumkin of the Geograp
The Atlantic Ocean becomes a meteorological mixing bowl from June 1 to November 30, replete with all needed ingredients for a hurricane recipe. NASA turns to its cadre of satellites to serve up a feast of information to the forecasters who seek to monitor and understand these awesome storms.
Typically, during the peak of hurricane season, from late August to mid-September, tropical cyclones of interest to U.S. coastal regions form around the Cape Verde Islands off Africa. NASA satellites ar
New evidence supports volcanic eruption theory
The extinction of the dinosaurs – thought to be caused by an asteroid impact some 65 million years ago – was more likely to have been caused by a mantle plume – a huge volcanic eruption from deep within the earths mantle, the region between the crust and the core of the earth.
This theory, already supported by a significant body of geologists and palaeontologists, is strengthened by new evidence to be presented
To do their jobs, water resource managers in the Columbia River Basin have mostly relied on data from sparsely located ground stations among the Cascade Mountains in the Pacific Northwest. But now, NASA and partnering agencies are going to provide United States Bureau of Reclamation water resource managers with high resolution satellite data, allowing them to analyze up-to-date water-related information over large areas all at once.
The pilot program is now underway with the Rio Grande and
