The Effects Of Hypoxia On The World

Ocean pollution is caused by many things,plastic,humans, and oil spills, we are trying to stop this. So many people just put the plastic in the ocean and people are trying to stop them. Two billion people within 30 miles of the coast create 100m of coastal plastic waste. We can help by reducing plastic in waste stream, and try to stop pollution. Another way we can help is by recycling (Doc.1). We cause pollution to by dumping trash and garbage onto beaches. We have to help protect oceans by monitoring the water to see if people can go swimming (Doc.2). The oceans have to stay healthy because they are a habitat to animals (OI). Another reason we have to keep oceans healthy because they are a big food source for us (OI). In

Oceans cover approximately 75% of Earth 's surface and are vital to this planet and the people who inhabit it. Oceans provide food, natural resources, and recreation for nearly everyone in this world. Unfortunately Oceans have been receiving mass amount of pollutants including oil spills, toxic waste dumping, and industrial dumping. These pollutants will have negative impacts on the wildlife in the ocean, as we are seeing already with the Coral Reefs, and soon enough it will begin to affect our lives as well.

Define the Problem: Describe the type of case and what problem(s) or issue(s) should be the focus for

3. Now create your presentation using a suitable template in PowerPoint. The presentation must be structured appropriately and must contain:

The CTDEP collected bottom- dwelling fish and invertebrates and compared the quantity of organisms and number of species with the levels of oxygen in the water. Both of these studies confirmed that severe effects occurred whenever levels of oxygen fell below 2.0 mg/l. Large reductions in the numbers and types of aquatic life present were noted. The lab experiments recorded reductions in both growth and increase in death.

should define the topics of discussion and articulate the problem that will be discussed in

It is called the Graveyard of the Atlantic because of the treacherous waters in the Atlantic

Earth's oceans are dying. “About 80% of the ocean around the world is polluted with chemicals industrial and residential waste, all of which comes from the land” (“Marine Problems…”).  Pollution is mainly coming from the people. Marine pollution should be stopped because it is the cause of many problems and if something is done about it, people will see an increase in sea life and healthier waters. It makes its way into the ocean and kills marine life. Ocean pollution is affecting the way of fisherman and their everyday lives. It is also very bad on the community because pollution is very bad on tourism. Ocean pollution should be stopped because it is poorly affecting marine life, it is not good for fishermen, and is very bad on tourism.

Briefly describe the problem or issue that you have decided to be the topic for your project proposal in order to orient your classmates and faculty

(Salton Sea Symposium, 1998) However , the condition of the Sea has drastically changed and so has the amount of healthy living organisms in the Sea. By the 1980�s the water level rose greatly and gave way to abandoned businesses, deteriorating structures and empty beaches. The above was due to the fact that evaporation is the only outlet to the Salton Sea , in fact 1.35 million acre feet of water is lost each year , thus increasing its salinity even more. The salinity of the Salton Sea has increased to 45,000 parts per thousand or 45 PPT; the Pacific Ocean is currently 35 PPT.

The dead zone in the Gulf of Mexico is a human problem, like most other disasters. What this means is that once the place thrived and was ecologically balanced, but we tipped the balance slightly and wrecked havoc upon the environment. It has been noted to occur since the 1950’s and is ongoing. The reason that this dead zone occurs is because of a phenomenon known as eutrophication. Eutrophication is when there is an excessive amount of nutrients in a body of water and it causes an abundance of plants to grow. In this case the nearby farms had been using nitrogen in their fertilizers. The nitrogen got carried into the ocean through rain and other forms of

Sediment collected from the riverbank as the river flows downstream is also a problem; it increases the turbidity of the river, and this makes it difficult for plants to receive the necessary sunlight needed for survival. When these plants die, there is less food for fish and other river animals. Bacteria levels also rise in the water, because it can cling to sediment very easily. When there is more sediment, there are more places for the bacteria to collect. (Helsel & Mueller, 2009). All of these problems are occurring as the water is flowing along the river banks, collecting even more sediment, and pollutants as it travels downstream and deposits into the Gulf of Mexico. When all of this sediment, nitrogen and bacteria flow into the Gulf of Mexico, it causes changes in the water there. The increase in the level of nitrogen causes plankton to grow faster. When the plankton decomposes it takes a large amount of oxygen out of the water. The bacteria break down the decomposed plankton, which releases carbon dioxide, taking increasing levels of oxygen out of the water in the Gulf. Eventually the level of oxygen decreases to a point where most living organisms cannot survive. Some animals flee while other plants and animals that cannot leave usually die. This is referred to as the Dead Zone in the Gulf of Mexico. (Gulf of Mexico; NOAA, 2009). With an expected increase in the size

Except for those who take a look and take the time to discover the causes. One of the many causes of the oceanic dead zones is synthetic fertilizers.

Dead zones in the ocean are so called because of the lack of oxygen in the seawater according to Karstensen. Oxygen is obviously needed to support all marine life in these areas. The article also mentions dissolved oxygen is

Choosing a topic is always the first step of any research process. The statement seems simple, but the chosen topic defines all other stages of the process. In order to choose a topic, one has first to identify a problem whose remedy or eradication calls for research. This is then followed by the development of a research question. The question forms the statement that serves as the research topic. The topic, which is the focus of the study, provides keywords for the next stage of research, that is, the literature review.
