Florida Red Tide

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

People are polluting the oceans which not only affects us but also affects the beautiful underwater habitats and interesting sea creatures. Two billion people within 30 miles of the coast create 100 metric tons of coastal plastic waste (Doc.1). This plastic waste can get caught around sea animals, injuring them or even killing them (OI). Oils spills can really hurt marine life (Doc.2). Some creatures could eat it or get covered in it. If the fish eats the oil and then someone or something eats the fish they could get extremely ill. When there are excess nutrients in the water algal blooms occur, which is when algae has too many nutrients and reproduces in large numbers, this can also hurt people (OI). For these reasons and many more we should

In Pensacola Bay the results of the Bay over time can be represented by various reports as in this report found in the years of 2007 and 2010 and from previous years in 2012-2013 reports for a rough comparison of data within past few years (2011-2014 period) and part of the first decade from (2000-2010 period). In the first set of data collected by Escambia County Utilities Authority (ECUA) that notes throughout the data on their table that demonstrates all values associated with samples taken as the Maximum contaminant Level (MCL), or the highest level of containment that is allowed in drinking water compared to Maximum Contaminant Level Goal (MCLG) that represents the level of water that represents no risk and allows for margin of safety (4). In the ECUA’s report the water quality from wells with which it uses to provide Escambia County its fresh water. Though this is not directly from Pensacola Bay, the ECUA report still reflects the

The causes that the ocean near Florida has turned into a guacamole, gunky sea is because of the algae and chemicals. The thick algae from Lake Okeechobee is making the manatees in the Atlantic Ocean struggling to breathe. The manatees are Native there and they are being affected from this man made disaster. There was a recent study, where scientists collected samples and tested it. The result was that twelve toxins that are health risking, according to Laura Parker from National Georgraphic.

A venomous marine fish, known as the Lionfish, is native to tropical regions in the Indo-Pacific Ocean. In 1992 Hurricane Andrew tore through South Florida and was labeled the most destructive hurricane in the history of the United States. The category five storm is thought to have caused the accidental introduction of the species into FLorida. An aquarium was devastated by the winds, and released several Lionfish into Biscayne Bay. That, along with owners who became dissatisfied with the animals after realizing they’d eat other fish, and ignorantly set them free in the Atlantic, allowed the organisms to populate the waters very quickly.

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.

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.

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

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

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

Not much can be done to stop the bleeding in the Florida Bay as of now but if someone such as myself who is only in high school can bring awareness to this issue, it shows how powerful and important this die off is to us in South Florida. If more people bring awareness to what is going on in the Florida Bay, we can eventually garner more attention to this issue from the government and environmental organizations around the world so we can work together to at least slow down the rapid sea grass die off and to think of long term solutions towards “Making the Florida Bay Healthy Again!” While I was down doing research on the water, I was angered and disgusted to see the water with a yellow “fog”, which is just a symptom of the sea grass-die off, imagine seeing the Florida Bay like this for years, without changing back to its original, beautiful, clear state

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.

Not only does the environment get wrecked but this algae has caused human death before (CRISPS). Off the northern coast of Sabah in East malaysia, 7 people died among 202 affected by Paralytic shellfish poisoning. This is due to red tide producing a class of neurotoxins called brevetoxins. These toxins not only get into our food supply but they become aerosolized by the surf and winds. When breathed in or ingested they are known to cause dizziness, numbness, vomiting, and even partial paralysis. Since this is still a relatively knew problem in the medical community, long term effects are still unknown. Among the neurotoxic effects, red tide can bring respiratory problems as I mentioned earlier. Getting up early to surf before school was a normal thing for me even when red tide was in full effect. I would come into school with bloodshot watery eyes, my skin and lungs burning only after an hour in the surf. The effects really sneak up on you if you don’t understand it is

Dribble! Pass! Take! Swish! Swoosh! Yes that is Kentucky, the best college basketball team to play for or just to watch. They have a good team put together. Those boys work hard and play smart together. Because they work together, I think it has gotten them very far.
