The geographical sciences website EurekaMag.com publishes insights into all areas of natural sciences including biology, agriculture, horticulture, forestry, geography, environment and health. Drawing from this pool of scientific disciplines, it publishes articles, reviews and insights on geographical sciences topics including those which have recently attained attention. While the Geographical Sciences Research Category contains over 36 million references, most of the reviews are included in the Geographical Sciences Keyword Category, the Geographical Sciences Keyphrase Category and in the Geographical Sciences Reviews Category of the online science magazine. The Geographical Sciences Subjects Category contains links to the most recently published reviews and insights. All content is now available on a user-friendly and fast Mobile m.EurekaMag.com Website.
The EurekaMag.com review of Aurora borealis covers the Northern Lights surrounding the north magnetic pole. They occur when highly charged electrons from the flarewind interact with elements in the earth's atmosphere. Solar winds stream away from the sun at speeds of about one million miles per hour. When they reach the earth, some forty hours after leaving the sun, they follow the lines of magnetic force generated by the earth's core and flow through the magnetosphere, an area of highly charged electrical and magnetic fields. As the electrons enter the earth's upper atmosphere, they will encounter atoms of oxygen and nitrogen at altitudes from twenty to two-hundred miles above the earth's surface. The color of the aurora depends on which atom is struck, and the altitude of the meeting. The EurekaMag.com review covers Aurora Borealis in the context of promoting tourism in the Northwest Territories (NWT) of Canada. Currently NWT's tourism industry is almost entirely based on its natural attractions including the Northern lights, with tourism operations focusing on ecotourism and adventure tourism. Seasonal problems with land transport infrastructure, a failure to promote cultural and heritage attractions in the region, the exclusive use of English for marketing and promotional activities, a lack of an appropriately trained and skilled workforce, and the absence of targeted marketing plans hinder the development of tourism in the NWT.
EurekaMag.com presents an insight into solar flares which are large energy releases at the sun's surface ejecting electrons, ions, and atoms through the sun's corona into space. Such emitted radiation can affect earth's ionosphere and disrupt long-range radio communications which, in turn, can disturb operation of radars and other devices. The EurekaMag review presents the effects of solar flarees on corn borer adults. The results proved that both the daily and annual catches were significantly modified by the Q-indexes, expressing the different lengths and intensities of the solar flares. On days with high Q-indexes, the number of catches are considerably lower whereas in years with low Q-indexes an increase as high as 45 percent can be experienced in the number of individuals collected. Another study shows that in January 2005, the solar active region NOAA AR 10720 produced five powerful solar flares. During this major solar activity several pronounced variations in the ground-level cosmic ray intensity were recorded. These flares produced energetic solar cosmic rays that caused a giant increase in the count rates of the ground-based cosmic ray detectors. At southern polar neutron monitor stations the increase of the count rate reached several thousand percent.
The EurekaMag.com review of solar storm covers the massive bursts of solar wind associated with solar flares. As such solar storms are caused by large explosions in the Sun's atmosphere and the interaction of the Sun's outburst with Earth's magnetic field. The review covers the Solar Environment Center (SEC) of the National Oceanic and Atmospheric Administration (NOAA). In 2004 the Solar Environment Center faced closure due to proposed funding cuts. The SEC which was the main US center for studying solar storms, had its $8.3-million funding request for 2004 rejected by the Senate subcommittee that determines appropriations to the US Department of Commerce, of which the NOAA is a part. On October 1, 2007 the NOAA Space Environment Center changed its name to the Space Weather Prediction Center (SWPC). The center is one of the nine National Centers for Environmental Prediction (NCEP)within NOAA's National Weather Service. The new name aligns the space weather center with the other NCEP centers. The latest news from SWPC state that after the arrival of a electromagnetic burst, called a coronal mass ejection (CME) on January 24, 2012 and the subsequent activity which ensued, conditions are now beginning to trend back towards quiet levels.
The Science Magazine EurekaMag.com was launched in November 1998 as the online version of the French science magazine "Eurêka - Le magazine des sciences" published since 1995. During the past decade, it has emerged as a comprehensive aggregator of information on biology, on the applied life sciences agriculture, horticulture and forestry, on the earth sciences, on the environmental sciences, and on the health sciences.
