Sea Water : Thermal Pollution

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

When salinity increases, warning signs appear in the landscapes of the affected areas. These warning signs include things like sick and/or dying trees, declining vegetation, colonisation of tolerant weed-like plants, bare patches where vegetation has died and saline pools in creek beds. These show that the ecosystem is being affected and at a high rate.

(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.

For an existing habitat, an increase in salt levels will begin to show an effect on the abundance and diversity in species of zooplankton. This will exhibit a detrimental effect on the daphnia from the limited osmoregulatory capabilities of the organisms. This in turn can pose a risk to the level feeding rates and survival (Heine-Fuster, Vega-Retter, Sabat & Ramos-Jiliberto,

According to World Health Organization (WHO) estimates, two billion illnesses and 1.8 million deaths related to contaminated food, human exposure to contaminated food is the most worldwide public health concern. Many people concerns about chemicals in food, food may be accidentally or deliberately contaminated by chemical hazards. Contamination occurs through environmental pollution of the air, water and soil, such as toxic metals, dioxins and PCBs, or through the use of various industrial chemicals, pesticide, power plant emission, chlordane, toxaphance, and DDT. These chemical substances which persist in the environment accumulate in the food chain, threats humans’ health and have enormous impact on the environment and society.

During the summers the oxygen content atop the water normally has a salinity level consistent with “more than 8 milligrams per liter”; but when oxygen content drops down to “less than 2 milligrams per liter” the water is then known to be in hypoxic state (CENR, 2000; USGS, 2006). Hypoxia is the result of oxygen levels decreasing to the point where aquatic organisms can no longer survive in the water column. Organisms such as fish, shrimps, and crabs are capable to evacuate the area but the fauna that cannot move either become stress and/or die. Due to this, many call the hypoxia zone the “dead zone” (Overview, 2008; USGS, 2006).

In the literature review, we stated that others have also shown that the higher the salinity, the higher chances of the brine shrimp surviving in the saltwater. We were uncertain about the brine shrimp of not having high survival rates in lower salinities, due to the brine shrimp species mainly don’t live in high salinity areas.

This article, “Oceans of Pollution” is written by Dahr Jamail. He presents this article with many details to support his argument. Two main topics with support are used, which is how plastic is causing a great pollution affecting the fertility rates of the fish because fish can ingest tiny sizes of plastic therefore harming the creatures. As well, another topic in this article is the dead zone affecting the ocean, caused by natural environment, climate changing the temperature and human factors. This article mainly presents this article to the government to suggest for change and to humans, many who are biologists, who care about this huge problem. With the intensity of the ocean’s pollution, the article uses three rhetorical topics, pathos,

During the 1990s scientist were able to collect 5,000 different salinity profiles. From their findings they were able to estimate a 20 percent increase in freshwater. Due to this increase there was a rise of fresh water by 8,400 cubic kilometer, which can be compared to the volume of fresh water and ice that is released in lower latitudes from the Arctic each year.

The results found that sea stars were negatively effected in growth rate by low pH, even lower in high temperature. Mussel growth rate was positively affected by low pH, however there was no response to high temperatures. Predation of sea stars on muscles decreased in lower pH by 50%. The overall effect shows that muscles perform better at the lower pH compared to the sea stars. Another study was done by Ferrari, M. C. O et al. (2015) which studied the effect of stressors, CO2 levels and temperature, on the predatory prey encounters in reef communities. Their method was to put 6 prey and one predator into 4 different treatments for 22 hours and record how many prey survived this was repeated 2 times for each of the 4 treatments. What the results found was that when both stressors were high, high CO2 and high temperature, the predation rate increased from 30% to 70%. Prey selection changed when it was either high CO2 or high temperature but when the stressors were together the prey selection was equal. Risk taking behaviour was also seen to increase during both stressors. A study was performed by Clements, J. C. et

How does the ocean look without pollution and with pollution? Well, this exhibit that I created to focus on the creatures of the ocean and the way oceans look the awning beauty of it. Then how the ocean looks after pollution is created and is put in the oceans waters and the effect of this. The oceans I will be focusing on being the Arctic Ocean, Indian Ocean, and the Pacific Oceans. Showing finally, how this beauty can be taken away so easily, giving us a before image, then an after image.

The oceans face many types of pollution every day, every second. The ocean is our greatest ecosystem and out most valuable resource. A common misconception is that the rainforests are the lungs of the planet however, the majority of our oxygen is made via the algae in the sea. The oceans feeds, hydrates, and provides us with oxygen; ironically enough, despite its monetary value to mankind, it is what is treated the worst. For ages we have been dumping our trash, chemicals, and waste into the oceans with no fear or regret, almost an “out of sight- out of mind” mentality. People once and still assume that the oceans are so vast that all of the pollution is diluted and would be dispersed through out, going unnoticed. However, dilution is a myth and an idea that renders ocean dumping to be less impactful. Even so much of the man made pollution is becoming even more concentrated and have entered our natural food chain. However vast the waters of the ocean are, they are not meant to house all of these external factors. There are many alternatives to marine pollution including recycling, finding alternative trash dump sites, cutting down on harmful chemicals for agriculture, and most importantly having the ability to recognize when a problem is developing and counter act, immediately.

Ocean pollution is one of the most urgent issues in our world today. The ocean is crucial to our ecosystem and it is being severely damaged at an alarmingly increasing rate. In this paper I will educate about the role the ocean plays in our beautiful Earth, why it is being so widely ignored and dismissed, the causes of pollution, and its effects on animals and humans alike.

What is thermal pollution? Thermal pollution is the sudden change in the natural temperature of bodies of water. Occurring usually when a plant, for example, a power plant or industrial facilities gain water from bodies of water and in which it is sent back to which it came from with a temperature that is altered. They use it as a method for cooling the machinery in their plants and facilities, and to help produce their products. In the world today, thermal pollution is seen as a huge threat to the environment and is mainly because of power plants and industrial manufacturers in which uses water as a coolant. Many attempts have been taken to manage how plants use the water, but effects of thermal pollution are still lasting to this day.

What is thermal pollution? Thermal pollution is defined as a sudden increase or decrease in the temperature of water those in which that are oceans, lakes, rivers, or a pond of water. It usually occurs when a plant such as a power plant or facilities gain water from a natural resource and exceeds to put it back with a temperature that is altered. They use it as method for cooling for the machinery in their plants and facilities, and to help produce their products.
