Ocean acidification research paper
Ocean acidification is a growing concern in the scientific community as it has the potential to significantly alter marine ecosystems and affect the livelihoods of people around the world. This process occurs when the pH of the ocean decreases as a result of the absorption of carbon dioxide (CO2) from the atmosphere. While the ocean has always been able to absorb a certain amount of CO2, the increasing levels of greenhouse gases in the atmosphere due to human activities are leading to higher levels of CO2 being absorbed by the ocean, which is causing its pH to drop.
There are several ways in which ocean acidification can impact marine ecosystems. One of the most significant impacts is on the calcification process of certain marine organisms. Many species, such as coral and shellfish, rely on the ability to build shells or skeletons from dissolved calcium carbonate in order to survive. However, as the ocean becomes more acidic, it becomes more difficult for these organisms to extract calcium carbonate from the water, which can hinder their ability to grow and reproduce. This can have cascading effects on the entire ecosystem, as these organisms are often at the base of the food chain and support a variety of other species.
Ocean acidification can also impact the distribution and abundance of certain species. Some species, such as pteropods (tiny snails that play a key role in the ocean's food web) are already showing signs of decline due to ocean acidification. Other species, such as certain types of plankton, may be more resistant to acidification and may thrive in these changing conditions, potentially leading to imbalances in the ecosystem.
The impacts of ocean acidification are not limited to marine ecosystems. Many communities around the world rely on the ocean for their livelihoods, whether through fishing, tourism, or other industries. As acidification affects the health of marine ecosystems, it can also have economic impacts on these communities.
There are several ways in which we can address and mitigate the impacts of ocean acidification. One of the most effective ways is to reduce our greenhouse gas emissions, which are the main driver of this process. This can be achieved through the use of renewable energy sources, more efficient transportation systems, and other measures that reduce our reliance on fossil fuels. Additionally, we can protect and restore marine ecosystems, such as coral reefs and seagrass beds, which can help to buffer against the impacts of acidification.
In conclusion, ocean acidification is a complex and multifaceted issue that requires the attention of scientists, policymakers, and the general public. By understanding the causes and impacts of this process, we can work towards finding solutions that will help to protect marine ecosystems and the communities that depend on them.
Ocean Acidification Research Paper
Surface sea water samples were collected inside the harbor at the Kashiwazaki-Kariwa Nuclear Power Plant of the Tokyo Electric Power Company Holdings 37°25. Drivers of pH variability in coastal ecosystems. The lower figure shows the long-term trends in the oceanic pH by season. This is particularly harmful for organisms with shells such as shell fish along with coral and others that build calcium-based shells. As reported by James Sadd, oil spills are caused by a variety of reasons, but more frequently due to mistakes made by humans. This has caused the process of ocean acidification; the research presented will show how this process is affecting our pH, ocean chemistry and marine life. This is as a result of the increase in CO2 levels surrounding the earth.
Research Paper On Ocean Acidification
We wish to express our sincere gratitude to Drs. Ocean acidification refers to the decrease in pH levels of the oceans. Synchronous bidecadal periodic changes of oxygen, phosphate and temperature between the Japan Sea deep water and the North Pacific intermediate water. Trends were defined and examined as follows. .
Lessons learned from ocean acidification research
Unfortunately The Importance Of Coral Reef Ecosystem 1337 Words 6 Pages Physiology Research Paper Materializing as individual forms of fossil records for over 400 million years, coral are known to be a highly archaic animal which many believed evolved into contemporary reef-construction that formed for the last 25 million years. Whether the DL and CL results indicate typical trends for other coastal areas in the Sea of Japan and Pacific remains unclear. Change 7, 241—242 2017. Table p-values, and correlation coefficients. Ocean acidification without borders. Comparison between the mean annual oceanic pH 25T time-series for the observed and expected values for the coastal regions of the Sea of Japan and North Pacific. Here, sea water samples were collected at an approximate water depth of 10 m at a rate of 75 m 3 h —1.
The distance from the intake to the sampling port was approximately 1 km, with a residence time of approximately 22 min. Raisman 1 This major environmental issue can cause certain species to be at risk of extinction. Time series analysis of pH data Trend The annual periodic component was fitted with a sine curve, and its value was removed from the raw data. Pespeni Nature Climate Change 2021. We then averaged each time series dataset for each year and calculated the standard errors. Ocean Acidification, as explained by Pacific Marine Environmental Laboratory PMEL, 2015 is a process which alters the seawater chemistry as evidenced by a decrease in the pH level of the ocean. Carbon dioxide CO2 plays a major role in ocean acidification due to high solubility of gas in the water.
Oak Ridge: Carbon dioxide information analysis center, Oak Ridge National Laboratory, U. Takashi Kikkawa and Masahiro Hayashi for their role in this study. Rate of Iceland Sea acidification from time series measurements. Ocean researchers and marine biologists are hopeful that some marine species that calcify for survival will be able to adapt to the changing pH levels in the oceans. When the ocean has a pH that is optimal then there Ocean Acidification Research Paper Ocean acidification is becoming on of the most concerning subjects compared to global climate change. Especially in the last two hundred years, carbon dioxide has increased in the atmosphere.
A time-series view of changing surface ocean chemistry due to ocean uptake of anthropogenic CO 2 and ocean acidification. This study examines long-term ocean pH data to evaluate ocean acidification OA trends at two coastal research institutions located on the Sea of Japan and the Pacific Ocean. Sci Rep 11, 5052 2021. Acidification takes place when …show more content… Funk and Wagnalls 1 Shell-forming animals, such as corals, mollusks, and planktonic organisms could experience reduced growth or death due to this increased hydrogen ion concentration. To remove the influence of water temperature, the pH data were normalized at 25 °C 25T.
In other words, X is the long-term linear trend component plus the decadal oscillation component Seasonality To examine and clarify recent seasonal changes in the pH, we divided these pH time-series into four seasonal periods March—May, spring; June—August, summer; September—November, autumn; and December—February, winter , and then determined a seasonally averaged value for each parameter. Sadd 2 Oil spills can be fixed, but oftentimes put so much pollution into the environment that no solution can take place quickly enough to stop the damages. This is happening because of increasing carbon dioxide emissions. Ocean acidification OA is a global environmental problem , but spatiotemporal variations in coastal water acidification are poorly understood. However, the locations of both laboratories were not directly affected by large rivers or industrial activities. Neither sampling system included a filtration tank.
The carbon dioxide that enters the sea this results in a change in the chemicals present in the Ocean thereby changing the equilibrium of the ocean due to different chemical ratios. Table p-values, and correlation coefficients. Biogeosciences 11, 1413—1423 2014. Ocean acidification does not mean that oceans are acidic; however it means that oceans are slowly becoming more acidic. The theoretical OA rate was estimated from atmospheric pCO 2 time-series data and estimated alkalinity. Difference from theoretical ocean acidification We evaluated by how much the measured OA rates differ from the theoretical OA trend.
Nature 425, 365 2003. They did not participate in the writing of this paper because of their organizational positions at the Demonstration Laboratory of the Marine Ecology Research Institute. Watanabe You can also search for this author in Contributions H. These gases can be from different elements, such as Ar-Argon, He-Helium, CO-Carbon Monoxide, C2H6 —Ethane, N2 — Nitrogen, and more. While the importance Research Paper On Ocean Acidification What is ocean acidification? This is due to the oceans absorbing around half the CO2 emitted through human activities and providing storage for the extra carbon dioxide.
Background dots indicate data. For the DL, the mean daily pH varies from 8. The harbor is a shallow bay on the landward side, created via the installation of a breakwater with a wide opening to the open sea. Previous studies have recognized OA as a problem caused by the ocean absorption of anthropogenic CO 2 released into the atmosphere —1 In this study, we examined long-term pH data from two coastal institutes located on the Sea of Japan and the Pacific Ocean collected over 30 years using identical measuring techniques. Scientist believe that the ocean has absorbed about half of the excess carbon dioxide in the past 200 years.
