In the course of the past year or so, the world has under gone immense natural disasters. Including but not limited to: hurricanes, tsunamis, wildfires, blizzards, and more. These unfortunate events all have a source of which they occurred. At the same time, the world’s oceans have under gone less noticeable but apparent changes as well. These changes include temperature variations, heightened acidification, intensified salinity, and more. However, a specific issue is the effect of Indiana’s activities impacting ocean life through nutrient and sediment pollution. There is a multifarious number of reasons that could affect ocean life, even in Indiana, which one will discuss throughout this report. One will describe sediment runoff, the …show more content…
One issue with this occurring is mere sediment availability (“Sedimentation & Erosion”). There is negative consequences from either increased sedimentation, or decreased sedimentation. For example, some disadvantages of increased sedimentation includes: increased water temperature, smothering of marine communities, filled water reservoirs leading to unnecessary costly dredging, increased deposition of toxic substances, and the damaging of fish causing irritation to their gills (“Sedimentation & Erosion”). The intriguing thing is, one may think that increased sedimentation could be a good thing. Although, too much of anything could be a problem in some aspects. However, there is also some issues with decreased sedimentation as well. For instance, some consequences for the decreasing of sedimentation includes: increased velocity within water which could lead to erosion, and the depletion of the ecosystem because of the lack of nutrients from decreased sedimentation. Therefore this affects oceanic processes merely because, the ocean has its exact amount of sediment it may need. Sediment provides immense nutrients to a lot of living organisms and more. So, this would affect the process of how the ocean would normally work. So, looking at it from an Indiana aspect, the decreasing or increasing of sediment occurs in Indiana, especially with the alternative weather patterns that occur, therefore
The Chesapeake Bay Watershed is considered of national high importance due to its 64,000 square miles and 17.4 million people inhabitants. However, this has not been sufficient to improve the health of the ecosystem over the last 25 years. The primary reasons for this lack of improvement are the lack of knowledge and information of the people living on the watershed, the multistate composition of the watershed and the broad range of activities that the watershed supports.
Our watershed, the chesapeake bay stretches more than 64,000 square miles and is home to about 18 million people.The bay provides us with a lot of things like fishes,salt and water for farming etc. But, the bay is starting to get polluted and many organisms in the bay are dying because of sediments, algae blooms etc.
Scientists and researchers began giving a large volume of effort and look into the extremely complex problems that face the Chesapeake Bay. When research for the improving and saving of the Bay’s overall health began it seemed very simple and there were only a couple of problems. The problems included nutrients from agricultural runoff; these nutrients were phosphorus and nitrogen. The combination of the nutrients in the Bay caused a large volume of algae that choked some of the marine life. While bringing in algae the nutrients also killed grasses on the seafloor. These seafloor bed grasses that once covered more than half of the Chesapeake Bay’s floor now only covered a tenth of their original area. Though the estuary was having problems it did not receive the terrible pollution from industries that many large rivers and lakes do in other urban areas (Brown, p. 397).
Studies have repeatedly shown that as oxygen concentrations decrease, the abundance and diversity of fish decrease (Breitburg). Fish kills, in which large numbers of dead and dying fish float to the surface or wash onto shore, are probably the most dramatic and publicly visible manifestation of hypoxia and nutrient over-enrichment of coastal waters(Breitburg). In addition to mass mortalities that are easily observed, high mortality of fish lacking a swim bladder can occur leaving little or no visible evidence of fish at the surface or littering beaches (Breitburg). With no fish, shrimp, or crabs the Louisiana fishing market takes a huge hit that the economy feels in a major way. The gulf accounts for almost one-fifth of the countries fishing landings, which total to be three billion dollars (Petrolia). Fishing is not only a major part of Louisiana’s economy but also its culture. Without wildlife in our waters microorganism are given more opportunity to grow leading to bacteria infected waters. These bacteria infected waters could cause major health risks for those who come in contact with
Did you ever wonder how things you do everyday effect the Chesapeake Bay watershed and Its tributaries? Well, It turns out to be not so good. One of the main causes for the Bay’s bad health are nutrients which are caused by excess nitrogen and phosphorus in the air and water. Plants and animals need nutrients to survive but when too many nutrients are in the water they fuel the growth of algae blooms and create conditions that are harmful for aquatic creatures.
The Chesapeake Bay is the nation’s largest estuary with six major tributaries, the James, the Potomac, the Susquehanna, the Patuxent, the York, and the Rappahannock Rivers, feeding into the bay from various locations in Maryland, Virginia, Pennsylvania, and the District of Columbia (Chemical Contaminants in the Chesapeake Bay – Workshop Discussion 1). These areas depend on the Bay as both an environmental and an economic resource. Throughout the last 15 years the Chesapeake Bay has suffered from elevated levels of pollution. Nitrogen and phosphorous from wastewater treatment plants, farmland, air pollution, and development all lead to reduced water clarity and lowered oxygen levels, which harm fish, crabs, oysters and
Marine pollution is not a new phenomenon, but our acknowledgement of its impacts and severity is relatively new, with the first laws and discussions to counter it only appearing in the 1950’s. For much of history, it was thought that the oceans were so large that any pollution created would be negligible and easily diluted (Marine Pollution). Since, countless research and laws have been implemented in order to preserve our marine ecosystems because of how crucial these ecosystems are to humanity.
The objective of this research is to determine whether or not Johnson’s seagrass endangerment is correlated to the amount of detrimental pollutants that humans are putting in aquatic ecosystems such as excess nitrates and oil from dredging. The critical prediction in this experiment is that as the concentration of a pollutant in the water Johnson’s seagrass grows in increases, the amount of growth decreases over time. The dry weight of the plant over time would decrease when grown in polluted water when comparing the dry weight of the plant when grown in clean water.
This spring, record breaking floodwaters along the Mississippi River caused massive damage in nine states, totaling over $25 billion dollars in damage (Watts, 2011). In most areas the floodwaters have receded, however there is concern that even a little rain could cause more flooding due to the already saturated land. As cities and towns are beginning the restoration process, one thing caused by the flooding waters cannot be restored. Pollutants’ such as nitrogen from fertilizer, due to this area being primarily composed of farming land, is making its way toward the Gulf of Mexico. Every year pollutants traveling in the Mississippi River enter the Gulf and contribute to the Coastal Dead Zone; however, this year the Dead Zone in the Gulf
The ocean is two-thirds of our planet a vast blue landscape home to many biomes which according to Boyce Thorne-Miller “(ecosystem types) corresponding to sets of environmental conditions that vary with depth, latitude, and longitude” (16). However, the ocean and its biomes is under attack from the changing environment. We can see this through coral reef biomes as they make their home near the shores. Through coral reefs we can view the effects that these changes have on the ocean through how the coral reef biome is affected. Humans are a danger to the coral reefs and the wildlife that resides in the biome. The pollution being released into the environment is poisoning the coral and causes death and malformation to the wildlife. The ocean is changing due to global warming which is causing a change in the temperature and rising water levels leading to a change in the stabile areas coral can survive. The increasing acidification of the ocean is causing the coral reefs to die. I will be looking at the effects these issues cause to coral reefs biomes and the ocean to see the similarities in how they affect both.
Oceans cover approximately 75% of Earth 's surface and are vital to this planet and the people who inhabit it. Oceans provide food, natural resources, and recreation for nearly everyone in this world. Unfortunately Oceans have been receiving mass amount of pollutants including oil spills, toxic waste dumping, and industrial dumping. These pollutants will have negative impacts on the wildlife in the ocean, as we are seeing already with the Coral Reefs, and soon enough it will begin to affect our lives as well.
Biscayne Bay is located in South Florida and is home to many terrestrial and aquatic organisms. Over the years, humans have populated the land around Biscayne Bay, which has greatly altered the water quality. In a study done in 2011, anthropogenic affects in the bay were measured by testing for an overabundance of nutrients in the water (Carey et al, 2011). This is just one of the many studies that shows how and why the Biscayne Bay is affected by human activities. A major concern with the increase in nutrient to the water is that it leads to an accumulation of algae, which ultimately causes a surge in algal bloom (Levinton, 2013).
Everything in this world we use comes from the ocean in some way. The air we breathe, the water we drink, even the products we use day to day, would not be possible without the ocean. That's why the issue of ocean pollution is so important and needs to be addressed as soon as possible. We depend on the ocean for so much in our life, without it we would surely become extinct. People seem to think that since the ocean is so large and vast, we can dump as much waste as we'd like into it and it will never have an effect on us. However, since we've been polluting the ocean as far back as Roman times, the evidence of ocean pollution becoming a major problem is all too clear.
As the world develops and the human population grows there is more pollution being dumped into the oceans, causing major problems to marine life and ecosystems. Major causes of marine pollution involve non-point pollutants, marine garbage, toxic ocean pollutants and sewage disposal in oceans. From heavy metal poisoning including lead and mercury killing predators such as sharks and whales, to waste getting trapped in the digestive tracts of marine animals, this essay focuses on how human interference causes horrifying problems to the marine life, but also how to fix it. It will also explore the normal activities of people including farming and how this can cause an imbalance in an ecosystem. Everyday activities can cause massive nutrient
In the article “Plan of Action: How to Clean Up America’s Beaches,” the National Resource Defense Council presents specific research their organization has conducted on what is causing the most pollution. The NRDC is a group of 350 lawyers, scientists, and policy experts looking to save the environment. Part of the NRDC is directed toward testing the rivers that lead to beaches, trash found on or in beaches, and what is found in animals to research what is polluting the ocean in the U.S. After conducting experiments to find what is causing beach pollution in each state, they then use the information to find ways locals and beachgoers can reduce their pollution. In their conclusion for Florida, they found that water runoff and sewage are what causes the most pollution in the local waters. Including
