Due to sea level rising coral reefs are getting destroyed, as they cannot survive in water above 25m. Also the increase of sea levels changes the nutrient flow, which will further damage the food chains. Furthermore coral bleaching is another side affect of global warming which affects the coral reef. Coral bleaching is permanent damage and is effected globally. It gets especially worse during an El Nino year.
A spill in any of the deep sea areas would reduce the biodiversity of that area through reductions of bird populations, fish-stocks and populations of marine mammals. All of which are already under severe threat of over fishing and habitat disturbance without this imposed threat. Furthermore the contamination of coastal and coral ecosystems will all lead to to damage on the livelihoods of fishermen and people involved the local tourism. The 2010 Deepwater Horizon oil spill in the Gulf of Mexico has been described as the worst environmental disaster in the United States, releasing about 4.9 million barrels of crude oil making it the largest accidental marine oil spill. Most of the impact of this was experienced by the marine species.
Many of the aquatic invertebrates are responsible for keeping the ecosystem clean by feeding on litters. Extinction of theses invertebrates would totally disrupt the balance of the ecosystem. The aim of this study is to bring awareness about the harmful impact global warming has on the local aquatic invertebrates and on the ecosystem at a global scale. The hypothesis for this study is that the biotic diversity of the slow moving water and fast moving water are driven by abiotic factors. To support this hypothesis, three predictions were made.
Abstract The objective of the south street seaweed experiment is to make a tincture of iodine. Iodine is used commercially as an antiseptic on cuts and scrapes of the skin. Conceptually, one of the active ingredients of the tincture, iodide, can be extracted from seaweed. By adding the seaweed to water and applying heat energy into the mixture, we were able to extract iodide. After adding Iodine salts, and filtering the mixture our next goal was to test for three important chemicals that must exist in our mixture for it to be a true iodine tincture; Iodine, Iodide Ion and the triiodide ion.
(live science.com) One of the most memorable rogue wave occurrences was on October 30, 1991. It was called the perfect storm. According to CNN.com, an enormous extra tropical low is creating havoc along the entire Eastern Atlantic Seaboard in this infrared image at 1200 UTC (0700 EST) on October 30, 1991. Labeled the "perfect storm" by the National Weather Service, the storm sank the sword fishing boat Andrea Gail, whose story became the basis for the currently best-selling novel "The Perfect Storm" by Sebastian Junger. Ocean waves peaked at 100 feet, the height of 10-story buildings.
Runoff Quality of the water flowing from the a\land is critical to the reef’s health. The ones near the mainland are the most damaged because of human activities. The land use activities near the coast increases freshwater runoff and the build up of silt. As more land is eroded by human activities the runoff increases destroying the vegetation. Fertilisers, sewage and pollutants can have direct impact on the coral reefs.
These runoffs have contributed to the beach closures, and the unsustainable condition of biological life in the lake. Human health is at great risk due to the untreated waste that is dumped in Lake Huron each year. The untreated sewage contains many viruses, two being Giardia (an intestinal parasite), cryptosporidium, which causes intestinal illnesses and even death. E. coli a more familiar virus has elevated its concentrations in Lake Huron, found in either animal or human feces, which causes diarrhea, nausea, and stomach cramps. ("Testing the waters,"
Estimates by the Red Cross and the Texas Department of Public Safety counted 468 fatalities, 100 persons missing and never found, and approximately 3,500 injured. Property and product loss, including 1.5 million barrels of petroleum products, totaled almost $5.5 billion in 2003 dollars. Finally, two thousand townspeople were left without homes at least temporarily, after one third of the town’s 1,519 houses were condemned (Richardson, 2005). Texas City is located on the Texas Gulf Coast, in Galveston County (Stephens 1997). It is on the southwestern shore of Galveston Bay, just off the Gulf of Mexico.
These emissions can become acid rain and if it can damage a tree, it can and does damage coral. According to the Coral Reef Alliance; the world’s oceans have had “approximately 525 billion tons of carbon dioxide” dumped by human activity within their waters. [ (Coral Reef Alliance, 2012) ]. The site also goes on to state that the destruction of Mangroves,(which have been harvested for lumber) and the loss filtering saltwater swamps due to farming have caused quite a bit of stress on coral reefs. Then there are the odd ways we humans go about “enjoying the ocean”.
Oil washed ashore on both islands resulting in one-thousand penguins being oiled and five-thousand birds died either during transportation or in the first few days after arriving at the rescue stations (Adams). Luckily, four-thousand-seven-hundred-eighteen penguins could be cleaned by the South African National Foundation and later returned to their habitat. The Apollo Sea tragedy was the largest South African oil spill for penguins before the sinking of the Treasure (Anderson). Shortly after, it became noticed that there was a larger number of seabirds at risk of being oiled off South Africa. Actions were immediately taken to help reduce the risk of more penguins becoming oiled.
