The Effects Of Algal Blooms On Coral Reefs

An estuary system is “the resulting collisions of sweet and salt-fresh river water flowing seaward and ocean water inland.” It is an aquatic system where salt and freshwater are constantly mixing. An estuary system is one of most active systems of the planet; it is a hybrid system that contains the best and worst qualities of the ocean, river, and lake systems it conglomerates. Estuaries are unique in nature because of their ability to be the most productive ecosystem on the entire planet; humans have attempted and failed to reach the productivity that estuaries naturally grant. There productivity lies it the constant change that occurs from the conflicting flows of fresh and ocean water. Ocean and freshwater are measured largely based on salinity, or the level of parts of salt per thousand. Ocean water usually

There are many destructive ways that the Florida red tide harms the living things along the Gulf Coast. Documented evidence in the past decade indicates that Karenia brevis red tide blooms exposures of brevetoxins were responsible for massive deaths among sea mammals, fishes, birds and sea turtles. These poisonous chemicals transferred through the food chain and all

In this research paper I will talk about how a large decrease in the algae population in the Chesapeake Bay will cause problems for not just fish and other species but the people who fish and make a living off of it. A large decrease in algae population will have a domino effect on the food chain. Having a major decrease in algae will hurt how others species live and protect themselves.

When there are excessive loads of Nitrogen and Phosphorous in the water, Alage can “bloom” to harmful levels, changing water color, and eventually stripping dissolved oxygen from the water when they die, fall to the bottom, and decay. This dissolved oxygen is critical to the health of the Chesapeake Bay’s critters and

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.

Algae blooms have been an issue in the Chesapeake Bay, especially in the Baltimore Inner Harbor. Algae is a natural and critical part of the ecosystem, however in large doses it is harmful to the plants and organisms within the ecosystem. Algae blooms can block out sunlight and kill other plants in the water. Algae depends on various factors such as water, nutrients and carbon dioxide to grow. Eutrophication of the Inner Harbor has lead to algae blooms that have caused large fish kills in the past. When there is an over abundance of certain chemical nutrients eutrophication can occur. Runoff from land and farms is the main cause of excess nutrients into the water. The most common nutrients that are related to algae outbreaks are nitrate nitrogen and phosphate. In addition, a lack of dissolved oxygen can also be an indicator for the process of eutrophication and risk of an algae outbreak. A particular type of algae commonly found in Maryland is known as Prorocentrum minimum. Prorocentrum tends to cause “mahogany tides” causing water to be brown and have an odor. There has been a campaign launched by the Healthy Harbor

Red tide is the common name for a large concentration of certain species of dinoflagellates. This event accumulates harmful algal blooms quickly, resulting in discoloration near the surface water. Dense enough algal blooms cause harmful toxins strong enough to affect people and the oceans ecosystem as a whole. Karenia brevis is the most troublesome species of dinoflagellate in the Gulf of Mexico. This species reproduces by asexual cell division, therefore, given the right conditions, the population can rapidly increase in size. K. brevis needs large amounts of the correct nutrients to reproduce at toxic speed. The nutrients responsible for supporting Florida's red tide are nitrogen and phosphorus.

The size of this algae ranges from microscopic, to macroalage, which is large, visible pieces of algae that form on the bottom of sediments.Certain types of algae can produce dangerous chemicals which are harmful to humans, wildlife, and aquatic creatures. Although these different algae are harmful, there aren’t enough of them to make a dent in the amount of life there is in the Chesapeake Bay. With such little amounts of toxic algae, much of it becomes a vital food source, which could cause an issue if the amount of it were to drop. Without this algae, many of the animals would begin to die off because there would not be be enough food for all of them. If this does happen, there would be many dead animals floating and decomposing in the water. The main animals that feed off the algae are smaller fish. Which, with these smaller fish dying, the larger fish and other animals would also begin dying off since the smaller fish are their food source.

As humanity continues to prosper agriculturally, industrially, and in population, companies, as well as local communities, have obsessively used the Ocean to toss their waste without consequences. The formation of dead zones has been intensified by the increase runoff of fertilizers and the burning of fossil fuels. Enhanced primary production causes algae to bloom at a constant rate creating a layer near the surface. This layer acts as a roof to vegetation below resulting in a lack of oxygen which organisms use to live. According to Robert Diaz and Rutger Rosenberg, “Dead zones have now been reported from more than 400 systems, affecting a total area of more than 245,000 square kilometers, and are probably a key stressor on marine ecosystems.” Specifically, the Chesapeake Bay has been polluted to the point where areas have now been uninhabitable to marine life. Although waste disposal is a difficult issue to solve, polluting bodies of water endangers the marine life, environment, and health of organisms.

As fresh water drains from land, it mixes with salt water from an ocean, and this water is called an

Red tide is a very serious issue that severely affects the West Coast of Florida. Red tide is defined as a toxic bloom in red dinoflagellates. It has major impacts on its surroundings. Algal species that have harmful effects are commonly referred to as Harmful Algal Blooms (HABs). Toxic red tide is threatening tourism in West Florida as well as wildlife, specifically the endangered manatees as it extends down the Florida coast. When conditions are right, dinoflagellates will bloom in very large numbers. Red tides name comes from the color that the blooms give the water when there are high concentrations of algae.

This red tide outbreak affects anyone and everyone who enjoys a day at the beach as well as Florida's marine life. If severe enough, it may negatively impact tourism in the area, thus denting Florida's tourist-dependent economy. In addition to targeting the local tourism industry, the seafood industry may suffer as well, as fish caught during red tide are typically inedible. If eaten, the infected organisms can pass along illnesses to those who consume them. As far as sewage exasperating the problem, it is important for the companies responsible to recognize and solve the issue, finding alternate ways to dispose of wastes.

Worldwide we are facing an epidemic of large-scale Coral Reefs bleaching themselves white. Although white coral is not dead it is likely to die shortly after bleaching. The main problem is global warming, this causes overfishing, pollution and rising ocean temperatures with more acidity. Global warming is an issue that affects our planet, especially in the ocean. This problem has also an economic and political impact because "If the reefs vanished, experts say, hunger, poverty and political instability could ensue."

Only, due to the constant stream of warm tropical water coming from the Caribbean, South Africa and the bay of Florida mixing with the waters from the Gulf of Mexico, which also create the tropical air temperature and humidity can they tolerate this location. When these two significantly, differently tempered water streams merge they create gyres (spiraling water currents). Kind of like an underwater hurricane.
