The Effects of the 1997-98 El Nino on Coral Reefs: Bleaching, Sea Surface Temperatures and Other Factors
[ send me this paper ]
This is a 9 page paper discussing the effects of El Nino on the world’s coral reefs in addition to other factors. Excessive and sudden high sea water temperatures, El Nino, have a devastating effect on the coral reefs in over 100 countries around the world. High sea surface temperatures cause a disruption of enzymes in the coral’s zooxanthellae which then create toxic byproducts which kill the living coral resulting in a whitening or bleaching effect. Coral bleaching has been used in the last decade to study the changes in marine ecosystems using methods which include a combination of marine and satellite imagery efforts. The El Nino of 1997-98 was particularly destructive to the coral reefs as over 16 percent were instantly bleached in that year. In addition to the effects of sea temperatures rising, El Nino and human environmental factors, over 27 percent of the world’s coral reefs have been severely damaged. While it has been found that 30 percent may be recovering from the 1997-98 El Nino disaster, some reefs found in the Caribbean have shown no signs of recovery since 1998.

The Endangered Species: Ivory from Elephants
[ send me this paper ]
5 pages. The African elephant is threatened with extinction and the trade in their ivory was forbidden in 1989 by the Convention on International Trade in Endangered Species (CITES). There is still, however, a serious poaching problem because ivory remains to be a highly sought after product. The implications of this illegal trade and the demand for it is discussed along with the organizations and groups that are involved. Bibliography lists 5 sources.

The Geology of Hydrothermal Vents
[ send me this paper ]
A 9 page discussion of the unique geology of hydrothermal vents. The subterranean processes which result in these vents also results in the expulsion of numerous minerals to the surface of the ocean floor. These mineral deposits form distinctive features which are potentially valuable not only from an aesthetic and ecological standpoint but mining standpoint. Bibliography lists 9 sources.

The Geology of the Grand Canyon
[ send me this paper ]
A 6 page paper discussing the stratification and
geological history of this haven for geologists. The allure for geologists is that the canyon
itself is geologically very young, but that the formations through which it is cut are very old.
This gives insight to the geological record that otherwise would not be possible. The paper
discusses the stratification and geological history of the canyon. Bibliography lists 5
sources.

The Great Dying
[ send me this paper ]
5 pages in length. The Great Dying is historically known as a period of time two hundred and fifty-one million years ago where the earth suffered significant and overwhelming devastation. The most intriguing aspect about this mass extinction of plant and animal life is that scientists still have no concrete evidence why such a phenomenon occurred. That the planet lost more than ninety percent of all marine plant and animal life, as well as nearly seventy percent of all land species, makes one ponder the underlying spiritual reasons for such havoc. Bibliography lists 3 sources.

The Greenhouse Effect; Causes and Solutions
[ send me this paper ]
This 6 page paper looks at the problem of global warming defining and describing some of the possible causes, such as carbon dioxide, water vapour and the natural temperature cycles. The paper also considers some of the proposed solutions to these problems. The bibliography cites 9 sources.

The Holographic Principle
[ send me this paper ]
A 5 page review of the holographic principle. Moving from an explanation using a shadow on the wall as an explanation of this theory, the author progresses to a more technical explanation involving cosmological theory. Bibliography lists 3 sources.
