The Chesapeake Bay is a very large estuary that holds more than eighteen trillion gallons of water (“The Bay Watershed”). This large estuary is part of six of the different states of Maryland, Delaware, New York, Pennsylvania, Virginia, and West Virginia (“Chesapeake Bay Program”). Some characteristics of the bay are salinity, temperature, and circulation. The bay watershed is home to seventeen million people and gains more people each year, so it is no wonder why there are pollution problems (“Chesapeake Bay Program”). The Chesapeake Bay is the largest estuary in the United States and is diverse with life. Though the bay is filled with life, it faces many problems caused by humans.
The three most important physical characteristics of the Chesapeake Bay are salinity, temperature, and circulation. Salinity is the measure of the amount of dissolved salts in the water and matters because certain types of fish and bay grasses need a certain amount of salt in the water (“Physical Description”). In general, the lower parts of the Chesapeake Bay are salty and the upper bay is mostly fresh, which means that the fish that need salt like to stay in the lower part of the bay. The fish that cannot survive in salt water will stay in the upper bay (Chesapeake Bay Program”).
Change in water temperature changes the places where grasses are able to grow, when fish and crab feed, reproduce, and migrate ("Chesapeake Bay Program"). The temperature in the bay goes from high in the summer to very low in the winter. During summer, the surface water is warmer than the deeper water which creates two different temperature layers that actually separate surface waters from deeper waters (“Chesapeake Bay Program”). The temperature layers change th...

... The Alliance for the Chesapeake bay is now trying to investigate the impact of human activities on The Chesapeake Bay. This proves that humans can make a difference to help save the Chesapeake Bay.
In conclusion, the Chesapeake Bay is the largest Estuary in the United States. It is diverse with many different plants and animals. The bay is made up of salinity, temperature, and circulation (“Chesapeake Bay Program”). The Alewife and the Atlantic Croaker are different, unique, and interesting fish with many interesting characteristics. Humans can have a great or terrible impact on the bay by forming groups to help protect the bay, and polluting the bay with agriculture, urban and suburban runoff, and air pollution from all the cars. The Chesapeake Bay has a very big area of information to learn about. That is what makes the Chesapeake Bay such a unique estuary.
By the 1700s the two regions, New England and Chesapeake varied greatly in spite of being from the same mother country, England. Physical and cultural differences separated these two regions distinctively. While religion moulded the daily life in New England, Money and tobacco farming dominated the Chesapeake.
First, the inhabitants of the New England area were far healthier. Their clean water supply was a sharp contrast to the contaminated waters of Chesapeake Bay. Air was also fresh and clean in New England. Chesapeake Bay colonists were plagued by disease due to their unsanitary way of life, and New Englanders could expect ten extra years of life because of migrating there in fact, on average, they lived to be nearly 70, close to the same life expectancy as today.
First off, to understand the climate of the Tampa Bay area, you must comprehend what is going on around the state of Florida. The first of many weather patterns that effect Tampa Bay’s climate are air masses. “An air mass is a large body of air
This ad is directed to many people in the Chesapeake Bay region because there are tons of pollution each year that are destroying the nation’s largest estuary, or part of a body of water where the fresh and salt water mix, and are also killing the Bay’s crabs, oysters, and fish, which is a huge industry in the area and also something the state of Maryland is known nationally for (Environment, p. 8). Pollution is destroying the Chesapeake Bay every single day, however now people are taking steps in the right direction to fix this problem but many people fear that time has run out.
The Chesapeake Bay is the largest estuary in the United States. It holds 18 hundred trillion gallons of water. The Bay is about 200 miles long, and is home to more than 17 million people. The importance of the Chesapeake Bay is incredible; two of the United States’ five major North Atlantic ports – Baltimore and Hampton Roads – are on the Bay. (Chesapeake Bay Program, n/d). The Chesapeake Bay provides shelter and food to all living things in the surrounding area. Both, people and animals, use the Bays resources every day and have done so for centuries.
Nature designed Florida to be one large marine ecosystem. Florida is one big sand peninsula located below the 40th longitudinal North American line. Three bodies of salt water (Gulf of Mexico, Strait of Florida and Atlantic Ocean) surround three out of four directions of Florida. Man-made canals, natural lakes, rivers and estuaries are confined within the State of Florida’s physical boundaries. All of these form an interlocking system of waterways that impact the interconnected marine environment (marine ecosystem). All of Florida’s waterways are connected back to the surrounding bodies of water while passing through Florida’s sub-tropical and temperate zones and impact the delicate marine ecosystem balance. Man and nature are causing a negative impact to this region like never before. Hurricanes, lack of green initiatives, garbage, pollution and the stripping of natural resources for population growth are decimating Florida’s natural ecosystems.
Being found in a Mid-Atlantic state but south of the Mason Dixon line Maryland can lay claim to a blend of Northern and Southern American traditions. Maryland has been influenced by English, American, and African American cuisine. Seafood is a prime ingredient in Maryland cuisine and is also the state's primary food product. Harvesting seafood in the Chesapeake Bay dates back to the Indians. Many Indians preserved their catches for winter by salting or smoking them. Chesapeake Bay oysters have been eaten for centuries. The Patuxent River has been an importan...
The Maryland Blue Crab is an essential part of the Chesapeake Bay; from the food chain of the creatures in the water, to the business side of the thriving demand for the crab during the hot summer months, but there is no denying the fact that the crab is just as important alive as it is when it is being harvested by local fisherman. By becoming more informed of the impact the crab has on Maryland’s bay and on the people who live around it, people can take bigger steps in making sure the crab will always be around for decades to come.
For many years now scientists and researchers have been paying their attention to the bay. Millions of dollars and hundreds of hours have been spent to return the bay to its glory. However, with all that has been done the bay is still in danger and the work is no where near complete. In 2005 the bay's health was evaluated at a “D”. (Chesapeake Bay Restoration)
The Long Island Sound is an estuary, and is in fact one of the largest in the world. An estuary is a place where salt water from the ocean mixes with fresh water from the rivers that drain from the land. Moreover, like other estuaries, the Long Island Sound has an abundance of fish and other waterfowl that add to the natural balance of the island, as well as one of the most important economic factors (Tedesco). Like other estuaries around the world, the Sound provides breeding, feeding, nesting, and nursery areas for many species that will spend most of their adult lives in the oceans (Long Island Sound Study). Despite these similarities to other estuaries, the Long Island Sound is unique from anywhere else in the world. Unlike other estuaries, the Long Island Sound does not just have one connection to the sea but it has two. It has two major sources of fresh water flowing into the bay that empty into the ocean. It combines this two-...
The Chesapeake Bay plays host to an astonishing amount of plant and animal life, providing much of our fish intake for species that aren’t being overfished. For the species that are being overdrawn, the Chesapeake Bay Foundation is working to restore the populations, and it’s going well thus far. Another theme that is endangering the marine life populations as well as the health of the human population is the massive amount of polluti...
... the residual effects of pollution left behind by both mining in the Chesapeake Bay area around rivers, such as the Susquehanna River in Pennsylvania, that feed into the Chesapeake Bay. Lutz also had quoted John Dawes, now the executive director of the Foundation for Pennsylvania Watersheds, on the damage done to streams and to the aquatic life in the streams. Dawes told Lutz "'we're looking at 4,600 miles of dead streams in Pennsylvania'" in reference to the vitality in polluted regions. This can occur in several ways but the two generally accepted causes are the toxicity levels in the water are too high to support life and the contaminated water is slowly killing off members of the food chains for the aquatic life. In either theory, the death of fish and their food chain caused by AMD is impacting the billion dollar fishing industry that calls Chesapeake Bay home.
Not only are they a critical part of the bays ecosystem, but they serve as a primary food source for humans living near the bay. Some examples of fish from the Chesapeake Bay Program website include: Striped bass, Atlantic Croaker, Atlantic Sturgeon, and even Sandbar Sharks. Fish are at the top of the food chain in the chesapeake bay and they take a large responsibility in keep the ecosystem in check. Some fish feed on almost any living organism they can find while others search the bottom for smaller nutrients. Fish even serve as a food source for scavengers such as birds living along the
Globally coastal wetlands are disappearing at an alarming rate, the problem is most of society does not realize the value of these precious wetlands. Coastal wetlands provide an important role in the coastal ecosystem. “Coastal wetlands provide critical services such as absorbing energy from coastal storms, preserving shorelines, protecting human populations and infrastructure, supporting commercial seafood harvests, absorbing pollutants and serving as critical habitat for migratory bird populations”(Anonymous, 2011). Coastal wetlands are an economical asset as well as an environmental one.
The oceans need to be protected because it is where life began and if not taken care of, life as we know it will end. When dangerous substances go into the ocean, ecosystems are suffer and become endangered along with lives of people and of marine life. Surfrider Foundation recognizes the importance of protecting and preserving the quality and biodiversity of the world's coasts because they are truly irreplaceable. There is also historical evidence of ocean pollution being present in the past, but the problem still lingers today. Heal the Bay discovered that,“Did you know there is a DDT and PCB hot spot off the coast of Palos Verdes? This superfund site (which indicates it's one of the most polluted places in the United States), is left over from a 1930's era chemical plant. Because DDT takes so long to break down in the marine environment, it persists to this day, contaminating certain species of fish. There are also highly polluted sediments in the Long Beach area, a sign of the heavy shipping in the port. Heal the Bay works on developing effective capping and removal plans to keep those toxins from spreading” (Heal the Bay). DDT is still highly concentrated in the South Bay area and still contaminating different species of fish. Even after more than 80 years DDT, a toxic insecticide, is still very concentrated and during upwellings, DDT particles come back up and continue to harm marine life. If humans are careless about what is thrown on the floor or sprayed on lawns, it can lead to disastrous affects when it comes to the condition of the ocean's ecosystems, and can endanger life itself leading to a problem that only we can mend.
