different approaches. Carbon dioxide is not good for ocean life and it is being absorbed by the ocean. Currently, the ocean is absorbing one-third of CO2 that has been admitted into the atmosphere. This lowers the amount of calcium carbonate in the seawater and without calcium carbonate, coral reef can’t grow. The acidification will impact many marine life directly that use calcium carbonate such as planktonic coccolithophores and other molluscs, corals, and coralline algae.…

Focus Research Question: What types of human experiments were done during the Holocaust? How far can human cruelty go? Enough to mutilate its own species? To be responsible for its agony and deaths? As shown by history, yes, humans are capable of such atrocities. In 1933, Adolf Hitler became the head of Germany. He had decided that certain races were inferior, so he began the Holocaust, exterminating millions of people for being born. Some of these victims were forcibly taken to concentration…

millions of people, as well as tourism and other sea-related economies. At its core, the issue of ocean acidification is simple chemistry. There are two important things to remember about what happens when carbon dioxide dissolves in seawater. First, the pH of seawater water gets lower as it becomes more acidic. Second, this process binds up carbonate ions and makes them less plentiful—ions that corals, oysters, mussels, and many other shelled organisms need to build shells and…

and a massive amount of energy is required. It is for these reasons alone that desalination of water should definitely not to be used or continued to be used to help solve this water crisis. Desalination is the long process of removing salt from seawater. Where the extracted salt is placed can have an enormous environmental impact on the wildlife, rivers, creeks, plants etc. That salt alone can kill the wildlife, animals and vegetation if it comes in contact with them. The desalination process…

the ring shape. The view of the seawater from this reef looks very exotic. One can even see the coral life under the seawater. One can just walk around this coral reef and enjoy the panoramic view of the sea fronts and the scenic landscape. The bay beach is the best place to relax in the beach sand. The shallow water makes a better place to swim for all ages. The kids too can venture the bay water, it is so clear that we can find where about of people in the seawater. This reef is the result of…

2.3.1 MAJOR PROCESSES 2.3.1.1 THERMAL PROCESSES (DISTILLATION) Around half of the world’s desalted water is produced with heat to distill freshwater from seawater. The process of distillation mimics the natural water cycle in that saline water is heated, producing water vapor that condensed to form freshwater. In an industrial plant or laboratory, water is heated to reach the boiling point to produce the maximum water vapor amount. To make it economically in a desalination plant, the…

3.3 Tribological properties of Cr-B-C-N coatings in artificial seawater Fig.10 shows the friction behaviors and the mean-steady friction coefficients of Cr-B-C-N coatings sliding against SiC balls in artificial seawater. As seen in Fig.10a, it is clear that the CrCN coatings showed higher friction coefficient than other coatings during the tribo-test in artificial seawater. The initial friction coefficient of CrCN coatings was 0.17, while that of CrBCN coatings ranged between 0.14 and 0.15. For…

This experiment analyzed the dissolved ions in a certain sample of seawater that was collected all around Galveston Bay and allowed an understanding of the composition of saltwater. The students were separated into four groups, each received a sample of seawater from a different location, such as Buoy 21, Day Mark 1, Pelican Island Cut, and the Coast Guard Station. The main ingredient in saltwater is water. Water is composed of two hydrogen atoms and one oxygen atom that are covalently bonded…

Though effectiveness and availability for desalination technology has been highly evaluated, why do some people oppose it? There are two objections against desalination technology. First, the process of desalinating seawater uses a lot of fossil fuel energy, so the cost management becomes very expensive, and it also increases greenhouse gas emissions. However, using renewable energy, which can be classified as solar, wind, photovoltaic, biomass, geothermal, and hydropower, has the potential for…

because rivers put freshwater into the ocean. Salt percentages can have either good or bad influences on marine life. Almost anything, including dissolved minerals from the earth’s crust, can be found in seawater. About 97 percent of earth’s water is in the ocean. The most important components of seawater that influence life forms are salinity, temperature, dissolved gases (mostly oxygen and carbon dioxide), nutrients, and pH. Scientists estimate that the ocean holds enough water to fill…
