Focusing on certain natural phenomena with explanation based on experiment data, natural sciences clearly explain the cause of marine contamination problems. Whereas social sciences use social theories and focus more on broader issues like social phenomena which do not explain clearly about contamination. It is important to do deep research because contamination in water especially in marine ecosystem is a very complex problem. Similar example is from tsunami disaster in Japan in 2011, radioactive which contaminated marine ecosystem is able to enter food chain and to accumulate in animal bodies. If human being consumes these contaminated organisms, toxic compound will be accumulated in human body.
Ocean acidification is killing off the oyster population, which is also affecting the jobs in Washington. Initially, ocean acidification is when acidic gases are emitted into the air and absorbed into the ocean. According to the video Ocean Acidification by NOAA, ¼ of all the carbon dioxide release into the air is absorbed into the oceans. Some major contributors to carbon emissions are automobile gas and factory emissions. This is a problem in the Pacific Northwest because acid sinks to the bottom, but Pacific winds bring acidic water up from the bottom near the shore by the shellfish.
Thus documenting high potential carcinogenic risk for fish consumption at Kharg island. Furthermore, biotransformation of PAHs in fish and other aquatic organisms generally accompanied by side effects resulting from the formation of carcinogenic intermediates (Johnson-Restrepo et al., 2008, Lazartigues
Negative Effects of Ocean Pollution “Each day, oil used to lubricate engines and to power the vessel leaks into the ocean” (Wroble 44). When the residue enters the ocean, it begins to affect the environment and animals. This is just one of the many problems from ocean pollution. “According to Worldwatch research associate Peter Weber, 80 to 90 percent of all of the materials dumped at sea are dredgings...dredgings are rich in toxic chemicals...from nonpoint sources” (Wroble 49). One particular chemical that affects the oceans are Polychlorinated Biphenyls, or PCBs.
Introduction In order for a coral reef to be productive and healthy, the water quality in the ocean should be maintained. Water quality not only affects coral reefs, but the other organisms that live on it and are involved with the natural food chain. Some of the factors that can influence water quality are nutrients, temperature, salinity, dissolved oxygen, turbidity, light, and chlorophyll present. Water is essential to every living organism because it helps with respiration, maintaining body temperature, digestion and provides energy. This experiment involved taking water samples from Ferry Reach off the BIOS dock and analyzing different factors to determine general conclusions about how water quality affects reef ecosystems.
However, all bioluminescence are utilized for similar reasons as it allows marine species to communicate, attract prey and mate at the depths of the ocean. The way for marine creatures to control the luminescent light is by the density of the bacterial population to form colonies. When a certain density of bacteria is reached, this cause the luminescent light produced. If creatures want to shut down the luminescent light, bacteria will be released out. However, the density of the bacterial populations is influenced by the oxygen and nutrient provided by the host that can result in slower growth rates if oxygen and nutrient levels are not maintained.
A subduction in the Earth’s crust is basically one of the plates is sinking under another plate. This causes a major disruption in the water leading to tsunamis we see today. Technology allows us to find the origin of the tsunami and which plates are moving below the ocean. It also allows us to figure out the total duration of the tsunami and raise in water level. When a ship goes down in the middle of the ocean suddenly there are two interpretations
Is there a difference in the boring mechanism of different Osedax species and has the mechanism been consistent over time? Bioerosion is an important process in nature because it changes the present environment. Typically, it is used to describe the process of breaking down a hard substance in the ocean by a living ocean. The bioerosion of coral into small particles results in the fine sand that show up on our beaches. Different organisms use different mechanisms for removing the substrate.
Negative Impacts Environmental Environmental impacts for example, Climate change, especially the rising ocean temperatures and Ocean Acidification is as of now influencing the Great Barrier Reefs Ecosystem. Coral bleaching coming about because of expanding ocean temperature and lower rates of calcification in skeleton-building life forms, for example, corals, because of sea acidification, are the impacts of most concern and are as of now obvious. Agricultural sources are adding to the waterfront and inshore territories of the Great Barrier Reef by expanded Nutrients, Sediments and different Pollutants in the catchment runoff. With the coastal population continuing to grow the coastal development grows which contributes to the modification
A question that many wonder about is why is phytoplankton important? Plankton is revealed by ocean color and help show scientists where ocean currents provide nutrients for plant growth. They also help show where pollutants are poisoning the ocean preventing plant growth and where changes in the climate of the ocean are occurring. Plankton is also the foundation of the oceans food chain. As phytoplankton begin to grow and multiply, small fish eat them, then the larger animals begin to eat those smaller animals.
