The situation can quickly turn into a global crisis. If it becomes less plankton, it means that fish and turtles will have nothing to eat, and if they begin to disappear, then the number of predators such as sharks and whales, also will be reduced. And it will be an echo of humanity for their actions, because less sea food will be available to
Ocean acidification leads to a reduction in the amount of carbonate ions in the water. Many marine animals essential carbonate ions for the calcium carbonate essential to form skeletons and shells. This will disturb their development and ability to reproduce – ultimately threatening their populations.. Falling numbers of less well-known species, like pteropods – tiny swimming snails – have important effects further up the food chain. Pteropods are important sources of nutrition for many types of fish, whales and birds in polar and sub-polar regions.
However, without the currents from the North Pacific Subtropical Gyre the patch would just float away. It is because of these currents that keeps it grounded and in place. The North Pacific Subtropical Gyre is created by the interaction of the California, North Equatorial, Kuroshiro, and North Pacific currents. These four currents move in a clockwise direction to generate a sort of vacuum that brings in debris from places like California or Japan. It is able to accumulate like this because the traces of debris are generally non biodegradable plastics which tend not to dissipate.
The topic of this research paper will cover over Ocean Acidification and the effects on marine ecosystems. Ocean acidification is the decrease in pH levels of the Earth 's oceans, due to overbearing carbon dioxide being brought by the atmosphere. The carbon dioxide is drawn by seawater, where the chemical reactions take place, which minimize the pH levels in the ocean, the carbonate levels and the important calcium carbonate which these sea creatures need. When carbon dioxide disperses in this ocean, it causes the levels of acidity to rise towards the the surface, where most shell growth in marine animals have been stopped and has created the cause of reproductive disorders in multiple fish. Part of the problem with ocean acidification is human activity.
This demonstrates how the country’s economy suffered. It lost the territories where the sea ports stood. They were no longer able to trade as much as they did before. Because they couldn’t trade, they didn’t make money enough to keep its economy stable and
This means that the protozoans would have a shrinking food source, which is an important limiting factor that has quite a considerable effect on the carrying capacity of the population of protozoans. This explains the missing protozoans, and the appearance of unmoving bacteria—replacing the usual moving, gray swath. This makes me think that pH9 did not directly kill off the protozoans; it simply killed off their food, lowering the amount of protozoans that could be fed in the habitat. I think that this explains the lack of anything living big enough to be seen, like nematodes, because everything in the food chain that size collapsed; all of the protists probably all died, and so did the fungi, such as mold, that weren’t able to decompose of the dead protozoans and other organisms. Also, the deaths of the protozoans in pH5 make sense, because acids, such as gastric acids (found in the
They can also be affected by changes in water temperature caused by occurrences like global warming. What Are Reefs? Tiny animals called coral polyps, or corals, create coral reefs. They produce a rock-like substance that forms a hard exoskeleton, or outside skeleton. Millions of polyps doing this over time create huge reefs.
The distant tsunami was able to have a fast speed as it was going towards open sea which meant that the water was very deep, and the local tsunamis had a very slow speed as the body of the water wasn’t that deep, it was shallow which caused the waves to slowly reach the shore. From (-- removed HTML --) I found this very interesting as I thought the local tsunamis waves would move very fast towards the dry lands and I would’ve thought the distant tsunami waves would move faster because it is moving into the open ocean. This allowed the Samoan citizens to evacuate to higher grounds to become more safe form the tsunami that was about to happen as Samoa is a very mountainous
“El Niño refers to appearance of anomalously warm water along the coast of Ecuador and Peru as far south as Lima (12°S)” (Trenberth, 1997, p. 2771). An El Niño causes above average sea temperatures over a period of four consecutive months in the Pacific Ocean. When the El Niño is present this means that conditions are favorable for an active hurricane season. Hurricanes weaken when it moves away from warm tropical water. This happens because the water tends to be cooler, atmosphere is much dryer.
Assessing the vulnerability of coastal fishing communities to climate change: A case study of pacific sardine fisheries, Japan. 1.Introduction Climate change has a substantial impact on marine resources (Hoegh-Guldberg and Bruno., 2010) and therefore on coastal community. Among the many marine resources, major concerns are mostly shown on fish due to its direct linkage to human food consumption and contribution to the protein intake. Likewise many coastal countries, fish is also one of the major seafood resources exploited in the waters of Japan. Japan, once the world's largest producer and still the major user of sardine fish, relies mainly on landings by her own fleet.
If the amount of grass is reduced in the ecosystem, the entire food chain will be affected greatly. Due to a smaller food source, the primary consumers, the savanna hares, will also experience a decrease in population since the new amount of grass can not sustain the initial amount of savanna hares. Since the savanna hare population decreases, the food source for the secondary consumers, the caracals, will also experience a decrease in population. The caracals do feed off of other animals, but it is likely these animals are also affected by the decrease in grass. The total food supply for the caracals decreased, so the caracals will experience a decrease in population.
I can use this experiment in my paper to show how ocean acidification will shift the balance of the ocean. If certain organisms lose their protective shells while others become more dominant, the entire food chain system will be thrown off balance for habitants of the ocean and land. I can also use this experiment to show how ocean acidification can also be beneficial for certain organisms to strengthen my rebuttal section. This article will be useful because of its in depth explanation of the experiment and use of primary
For years it was thought that carbon dioxide absorption into the oceans would benefit the environment as it reduced the amount of greenhouse gasses present in the atmosphere. It became clear after careful observation of the oceans over time that excess carbon dioxide created a chemical reaction in the water that resulted in the release of free hydrogen in larger-than-average quantities. This led to a dramatic increase in oceanic acidity levels and became highly damaging to marine life, the chemistry of which is explained below. It is estimated that 30 to 40% of all anthropogenic carbon emitted into the atmosphere is absorbed by oceans. When CO2 reacts with water molecules, it produces carbonic acid (H2CO3).
This rising air, which is very moist, cools and condenses, which forms clouds. Even though it is warm enough at the equator, hurricanes can’t form there because there is not enough rotation. There are a few additional conditions that must also be met for a hurricane to form. First, the water that the storm forms over must be over 80 degrees Fahrenheit. Second, there must be little wind shear so the clouds stay intact.
This means that n-butanol will have less tendency towards cavitation and vapor lock problem, which can eliminate the need for very special blends during the summer and winter months as the gasoline. As the heat of vaporization of butanol is less than half of that of ethanol, an engine running on butanol should be easier to start in cold weather than one running on ethanol or methanol. In addition, the auto-ignition temperature of the n-butanol is lower than ethanol or methanol, which also results in less ignition problems at cold start or low load conditions. As butanol has a very low vapor pressure point and a high flash point, it is a much safer fuel to use in high temperatures (134). One advantage of butanol over ethanol is that it is much less anhydrous, which greatly reduces the risk of water contain absorption by the fuel, with a higher latent heat of vaporization, butanol is expected to have lower indicated specific fuel consumption.
