variety of factors, such as the nutrients in that environment, temperature, light levels, turbidity, and stable conditions (Department of Primary Industries, 2009). The mass growth of algae is known as an algal bloom. This large population has negative effects on the surrounding environment. Algal blooms have been linked to pollution spread from agricultural runoff in studies conducted at Stanford University in 2005 (Stanford Report, 2005), with the high levels of nitrogen/phosphorus used in the fertilizers

Introduction Red Tide, commonly labeled as Harmful Algal Blooms (HABs), is a natural phenomenon that is caused by an explosion of algae in coastal waters. The algae are single celled protists; plant-like organisms. Because the algae reproduce expeditiously, they manage to alter the color of coastal oceans. However, the name "Red Tide" is a misnomer; many times, the ocean can be multiple colors, ranging from green to blue to yellow. Overall, Red Tide has many negative effects on the environment as
paper is to provide information about the different kinds of algal blooms and their effect on our environment and ourselves. There are still a lot of things that are not known about the algal bloom phenomenon, and many different hypotheses have been presented to explain these. Throughout the course of this paper those hypotheses will be presented and discussed, allowing the reader to derive their own opinion about the origin of algal blooms and what will happen in the future. table of contents

Algal Blooms and Their Effects Over the past years, due to warming waters, a toxic kind of algae called Pseudo-nitzschia has been blooming. This toxic algae affects sea life, especially marine mammals such as sea lions, which die of brain disease after feeding on this algae. This research paper will provide the reader with a conclusion in respect to what causes algal blooms and how we can prevent them. Pseudo-nitzschia is a type of algae that produces a very strong neurotoxin called Domoic Acid,
stress and/or die. Due to this, many call the hypoxia zone the “dead zone” (Overview, 2008; USGS, 2006). Because of farm fertilizer, an excess quantity of nitrogen and phosphorus can be wash down becoming runoff into rivers. From this, marine algal blooms cause the water to turn green from the chlorophyll (Reed, 2011). Eutrophication then becomes a dilemma in the system causing either an increase of primary production or an expansion of algae. An enormous expansion of phytoplankton on the water’s
Eutrophication comes from the Greek word "eutrophos" meaning well-nourished. In other words, this natural process found in water occurs as a result of additional rich nutrients forming a flourish in plant production. At this moment in time, eutrophication is causing worldwide devastation to not only aquatic life, but the fishing industry. The release of nutrients into fresh water lakes, rivers and reservoirs leads to excessive growth of three different plant species: a) Open water algae (phytoplankton)
single celled and free living organisms in the ocean. Dinoflagellates cause the Harmful Algal Blooms (HAB) also known as the red tide effect (Hackett et al 2004). Toxicity persisting at upper levels of the food chain is detected in them from the ones which are toxic, but not all such blooms are toxic. Enhanced detection capabilities may in part contribute to observed high frequency and severity of toxic blooms. As they are also important in the health of coral reefs their study has gained significant
chance of other native species to grow and better the environment. Furthermore, by restoring the environment of Honeysuckle it It affects the states surrounding the Gulf of Mexico, such as Texas (epa.gov, 2016). It costs a great amount to restore algal blooms and remove Nitrogen nutrients from the water. Sometimes it can cost billions of dollars to clean polluted water. Also, the tourism industry loses about one billion dollars a year from polluted waters, in fishing and boating. (epa.gov, 2016) Nutrient

depletion and problems in water treatments. Eutrophication is currently happening to many of the Canadian Lakes including Lake Winnipeg. Since 1969, it has been observed that Cyanobacteria (blue-green algae) has been the reason for the 90% hike in the algal blooms.Cyanobacteria causes a smelly odour and releases toxins that are detrimental to humans and some other organisms. When the lake is enriched with phosphorus, cyanobacteria thrive due to nitrogen-fixing. Due to the unfair advantage cyanobacteria

algae bloom that releases toxins into the ocean and releases horrid smells that can leave you with respiratory problems like hacking horribly, minor cough , or asthma in worse cases. The algae bloom releases toxins when its in a high concentrated state into the ocean that the shellfish take in but they don’t die. Instead they concentrate all of it into their body’s in a small space and if a human eats the shellfish the human has a huge chance of dying because of the toxin. The algae bloom also affects

Humans are the biggest threat to their existence. Humans have carelessly injured and killed thousands of manatees by slicing and dicing them with boat propellers, all in the name of entertainment.

affect water pollution, and can be a big problem. Whether if fertilizers are organic or artificial, if they get into water ecosystems, they can cause very large problems. The fertilizers will cause an algae bloom, which can later cause dead zones. Dead zones are spots in which large algae blooms happened, and there are very little animals in the marine zone. Fertilizer pollution interacts with economic and political issues, and many things must be done in order to help resolve the issue. When Fertilizers
Some diatoms are benthic and live on mud, seaweed, and other surfaces. Other diatoms are wholly plankton and float in the water column. What type of adaptations do you expect each type of diatom to have? In other words, how do some diatoms stay afloat, while others stay attached to the benthos? Some of the diatoms are able to stay afloat because they have more surface area, meaning they have extended body parts that catch the water and make them sink much slower. While other types of diatoms
Recently, scientists have been noticing a quite thing occurring in the ocean that had never been seen before. Scientists have been recently finding a new type of algae in the ocean that does not have very great effects on the environment. Many say that this alga is probably a type of algae that is similar to the ones that grew millions of years ago; this alga is toxic though. It releases terrible pungent odors that can affect health. This algae was first discovered in Australia by fisherman and is
The Benefits of Algae How often also does a human use or eat algae in his daily life? When most people think of algae, they probably think of something that is slimy, gross, and dirty. Algae may irritate people because it grows in unwanted places like swimming pools and boats. Algae can be toxic and it is slimy, but algae benefits people in all aspects of life. Humans obtain algin from algae to help make ice cream, pudding, face cream, and shoe polish. Algae is present in hamburgers
