Eutrophication

Imagine, you're walking down the street, and you suddenly lose your breath, you find it impossible to breathe, now you're slowly suffocating and your oxygen has been completely depleted. If this were to happen it would be a terrible scenario and it's a reality for some fish and other marine life in the Gulf of Mexico. The area in the Gulf of Mexico that is noted for oxygen depletion is called the “dead zone”. A dead zone, also known as a hypoxia zone, is an area with little to no dissolved…

The great lakes have been around since the tail end of the Ice Age. Now 2.6 million years later, the great lakes are facing huge problems. The great lakes have now been suffering through pollution, invasive species, and habitat loss. These are some of the reasons why. The pollution in the great lakes is not great, but its not horrendous. The text explains that pollution is in the great lakes, but other evidence explains that the great lakes pollution has gotten better since the 60's. In fact,…

Nitrogen Script Shea: The indicator we chose for this project was Nitrogen. Anjuna: Nitrogen is a chemical found in fertilizers, air pollution, factories, homes, and septic tanks. It dissolves in the run off and becomes part of the Chesapeake Bay. Then it feeds algae, which blocks sunlight from plants and animals then during decomposition, creates dead zones that steal the oxygen from the plants and animals. It kills the animals and plants which disturbs the ecosystem. If more dead zones…

The choice of a pond filter biomedia is critical to the health of your fish pond. In the biomedia of a fish pond filter, bacteria colonies work to purify the water. The better the biofilter, the smaller your homemade pond filter needs to be. And don't worry, pond filters are relatively easy to make. The first consideration when building a fish pond filter is SSA, or specific surface area. See the chart below, where SSA is measured in square feet per gallon of different pond filter biomedia. A…

Environmental Data Analysis The school that I attended was Page High School, located in Page, Arizona. Page is located in Northern Arizona, established on a mesa on the Arizona-Utah border, and has a population of around seventy five hundred people. Based off the air quality report conducted by the U.S. Environmental Protection Agency (EPA), the two most present toxic chemicals present outside of the school are sulfuric acid and manganese. Sulfuric acid is found most commonly in fertilizer…

This is a paper about a the Chesapeake Bay and how its food chain works, what the roles of the organisms are, the possible effects of a decrease in population of the algae, plants, and animals, also the possible causes for this and why as well as the preventions being done against this as well as the fixing of them. Also what else could be done or should be done about the issue. That is the main topic and subject this paper is gonna talk about. There are many organisms within the Chesapeake Bay…

Out of the 13 tests taken at each of the 4 sites, 4 tests will be chosen to compare and contrast the difference in values and reasoning behind those sites. Potassium ion, calcium ion, conductivity, and dissolved oxygen will be compared from Lake Mary, Colorado River Float, Lake Powell Marina, and Lake Powell Swimming locations. These 4 tests will be compared as it takes into account three popular ions found in most bodies of water (salt, calcium, and potassium), as well as the oxygen levels…

Title: Ecological Interactions of Living Organisms in Beaver Creek Statement of the Problem: How do the organisms in Beaver Creek interact with the biotic and abiotic portions of the ecosystem? The sample was taken from Beaver Creek (a tributary of Tookany Creek) in Glenside, Montgomery County, PA. The pH of the creek was 5.5, and the stream velocity was detectable (greater or equal to walking speed). In the area of collection, the stream width was one meter and the depth was 14 cm. There…

The purpose of this lab was to determine what vegetation was present above and below the water’s surface and to observe the water visibility depth at Noxubee Refuge. We collected samples of data from the two different lakes at Noxubee Refuge. The two lakes were Bluff Lake and Loakfoma Lake. The Bluff lake consists of 800 acres of the Noxubee Refuge, and Loakfoma Lake consists of 400 acres (About the Refuge). Many different wildlife species are present at these two lakes. The wildlife…

John Taylor ALEC 440 November 14, 2014 Save the Nolichucky from U.S Nitrogen Imagine living on a magnificent river your entire life; not only living on the river, but relying on that river for your livelihood. Now, imagine that magnificent rive being threatened by pollutants,that is what the citizens of the area surrounding the Nolichucky River are facing as we speak. Those citizens depend on the river for drinking water, irrigation and sustainment of their livestock; not to mention the…
