81. Earth Impact Effects Program
    Online calculator for cratering effects of hypothetical asteroid impacts.

    Extractions: Earth Impact Effects Program Robert Marcus H. Jay Melosh , and Gareth Collins Welcome to the Earth Impact Effects Program: an easy-to-use, interactive web site for estimating the regional environmental consequences of an impact on Earth. This program will estimate the ejecta distribution, ground shaking, atmospheric blast wave, and thermal effects of an impact as well as the size of the crater produced. Please enter values in the boxes below to describe your impact event of choice and your distance away. Then click "Calculate Effects" to learn about the environmental consequences. Distance from Impact Distance from Impact km miles Enter Impact Parameters Impact Examples Projectile Parameters Projectile Diameter m km ft miles Projectile Density (in kg/m or Select from a list 1000 kg/m^3 for ice 1500 kg/m^3 for porous rock 3000 kg/m^3 for dense rock 8000 kg/m^3 for iron Impact Parameters Impact Velocity km/s miles/s This is the velocity of the projectile before it enters the atmosphere. The minimum impact velocity on Earth is 11 km/s. Typical impact velocities are 17 km/s for asteroids and 51 km/s for comets. The maximum Earth impact velocity for objects orbiting the sun is 72 km/s. Impact Angle (in degrees) The impact angle is measured from a plane tangent to the impact surface. This angle is 90 degrees for a vertical impact. The most probable angle of impact is 45 degrees.

    Extractions: Soil erosion by water, wind and tillage affects both agriculture and the natural environment. Soil loss, and its associated impacts, is one of the most important (yet probably the least well-known) of today's environmental problems BBC 2000 Guardian 2004 "The threat of nuclear weapons and man's ability to destroy the environment are really alarming. And yet there are other almost imperceptible changes - I am thinking of the exhaustion of our natural resources, and especially of soil erosion - and these are perhaps more dangerous still, because once we begin to feel their repercussions it will be too late." (p144 of The Dalai Lama's Little Book of Inner Peace : 2002, Element Books, London) It isn't easy to find comprehensive information on erosion, however. To a large extent this is because soil erosion does not fit neatly under any one heading: it is studied by geomorphologists, agricultural engineers, soil scientists, hydrologists and others; and is of interest to policy-makers, farmers, environmentalists and many other individuals and groups. The Soil Erosion Site brings together reliable information on soil erosion from a wide range of disciplines and sources. It aims to be the definitive internet source for those wishing to find out more about soil loss and soil conservation.

88. Karsts Of Australia
    Short discussion of karst development in Australia.  
    http://wasg.iinet.net.au/karsts.html
    
    Extractions: Australia is well known as a dry continent; this reputation can be best demonstrated by the fact that two thirds of the continent has no runoff at all. One third has less than 250 mm of rainfall and the 750 mm isohyet is rarely more than 250 kilometres inland. Much of the remainder is only seasonally or episodically moist and therefore karst processes can only operate for relatively short periods. The fact that many of the larger bodies of soluble rocks are found in the drier areas further reduces the opportunity for karst development. Even the well watered fringe is subject to extreme variability and the precipitation/evaporation ratio generally does not favour the ready availability of water.The distribution of Australian karsts is shown in Figure 1 ; this is about 4% of the continent and is an underestimate due to incomplete geological mapping. . It should be noted that a much larger area (around 15%) is underlain by limestone groundwater basins with a thick overburden of Quaternary deposits. Climatic control of karst development can be seen dramatically in the difference between the dry Nullarbor Plain and the moist southeast of South Australia. Although the lithologies of the horizontally bedded, Tertiary limestones are very similar, the latter has extensive karstification in stark contrast to the Nullarbor. This may in part be due to watertable change through tectonics as well as sea level fluctuations. Sea level changes have had an influence on the development of the Nullarbor caves but it may well be that the karst features of the Nullarbor are relics of former, more effective, precipitation regimes. There is, however, little evidence for this over the fifteen million years that the limestones have been above sea level.

Recent (2005) photos of C-bays The Age and Tropic History of Lake Waccamaw, North Carolina Sediment cores were collected in Lake Waccamaw, a Bay Lake in southeastern North Carolina. The cores were analyzed for information that might be relevant to concerns about the age and trophic status of the lake which is home to several endemic species. Analysis of the diatoms and sponge spicules in the sediments revealed that the lake has always been nearly eutrophic. Analyses of sediment carbon and phosphorus content also support this view. The sediment record indicates that Lake Waccamaw has had periods of shallowing followed by deeper phases. Our interpretation of the geologic history of the Lake Waccamaw area, the sediment record, and the relevant data of others is that Lake Waccamaw is a relatively young lake, probably around 15,000 years old or less. The presence of endemic fauna in the lake is probably a result of the lake's unique chemistry and productivity and not the result of a long period of reproductive isolation from other populations.

94. Beach Restoration And Erosion Control
    Provides information on a program to preserve and protect the California shoreline, minimize the economic losses caused by beach erosion and maintain urgently needed recreational beach areas.  
    http://www.dbw.ca.gov/Environmental/Beach.aspx
    
    Extractions: Skip to: Content Footer Accessibility Search: California This Site CA.GOV Site Index The general objectives of the program are to preserve and protect the California shoreline, minimize the economic losses caused by beach erosion and maintain urgently needed recreational beach areas. This can be achieved by: California's coast, one of our most precious resources, is a naturally eroding shoreline. It is both economically and socially important to minimize the loss of the State's beaches and to preserve its coastal resources. When erosion threatens to damage valuable infrastructure, or there is not enough beach width to accommodate the recreational needs of the local population and the State's many visitors, beach erosion control projects at carefully selected places can halt the erosion. Much of the natural sand that replenishes the beaches has been prevented from reaching the coastline by increasing urban development and flood control projects, especially in southern California. On the other hand, hundreds of millions of cubic yards of sand have been supplied to the shoreline over the past 50 years, mainly in southern California, as a byproduct of coastal projects such as harbors, sewer plants and power plants. This vast quantity of sand has widened many beaches well beyond their natural size. The beaches from Santa Monica south to Palos Verdes in the Los Angeles area, and those from Coronado to Silver Strand near San Diego, provide excellent examples of beaches widened by nourishment.

    Extractions: 10 Months after treatment Patented beach restoration technology reverses erosion without the addition of artificial fill, and independent university studies verified that there were no adverse side effects to adjacent shorelines. The system has successfully restored more than 100 miles of beaches on Great Lakes and ocean shorelines. Studies demonstrate that the technology is a true breakthrough in coastal erosion control. System cost is significantly less than traditional methods because storm energy itself is harnessed to produce lasting benefits.

At the time, I was an airman in the US Navy aboard the aircraft carrier, USS John F. Kennedy. As we launched our first air strike that night, I wondered where I would be in ten years if I survived the war. Interestingly, it was ten years later to the day that I left for the Yucatan to begin what would be an event of equal magnitude in the effect it will have on my life. For me, this expedition was more than a simple trip, more than a learning experience... it was and shall remain a symbol of how far I've come in the ten years since feeling the most uncertainty I have ever known. My future is clear to me now. I like where it's going. It's still an extraordinary adventure. For the best imaging, check your monitor’s color settings:
