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 well as the health of both humans and animals alike.
Causes of Red Tide
There are many causes of red tide, such as warm ocean surface temperatures, low salinity, high nutrient content, and calm seas. Often, red tide can be carried over to other places by winds, ocean currents, storms, or ships, so it is found all across the globe and nearly impossible to predict. In the Atlantic coast, the algae responsible for the red tides are called Alexandrium Fundyense. In the Pacific coast, the algal bloom liable for the Red Tide is called Alexandrium Catenella. In the Gulf of Mexico, the algae responsible are Karenia Brevis.
Red Tide's Effect on the Environment
Red Tide algae create natural brevetoxins, which are toxins that can be introduced to the body through inhalation and ingestion. Through bioaccumulation and biomagnification, Red Tide algae can easily poison and kill consumers higher on the food web, such as large fish. However, grazers such as krill are unaffected by the miniscule amount of toxins in their bodies. However, as the algae and their toxins go up in the food chain, they become more concentrated in individual organisms, often causing sickness, then death. As a result, millions of fish can die due to ingestion of the toxins.

On average a given spot will experience two high tide and two low tides in a day. The tides are experienced due to the moon gravitational pull. The low tides are experienced when we are facing 90 and 180 degrees away from the moon. Then the high tides are found when we are facing the moon and when we are facing away from the moon.
cut back on the problems in the Bay. Scientists have given an unthinkable amount of attention to the Bay of the past several years and researchers from countless numbers of agencies and institutions have dove deep into the issues and studying every nook and cranny to create answers to every politicians’ questions. The biggest concern with the Bay, and the most concentrated ...

Carson has written this essay to provide insight about the tide currents of the deep waters. She also raises insight awareness on planetary forces and physical dimensions. Carson’s main focus consists on informing the readers about the size, timing, and occurrences the tides correlated with. Statistics and studies are given to further elaborate and assist Rachel’s theory that states “In every country the moon keeps ever the rule of alliance with the sea which-it once for all has agreed upon." From the tone of the essay, it can be seen that the theme contains educational content that has significant importance to the global being.
The bay's harvest and many of its other attractions bring tourists and in turn revenue for the area. Oysters and blue crab are a big part of the culture in the bay area. However, these organisms are in danger and need help. Description of the problem Eutrophication is a concern in the Chesapeake Bay. Eutrophication is caused by excessive amounts of nutrients.
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...
According to the Worldwatch Institute the rapid industrialization has polluted many lakes and streams resulting in chemical pollution and increased algae blooms leaving the water undrinkable. These combined issues are then causing knock on effects to the aquatic life by staving them of oxygen. Many areas are also suffering with an increase in dust storms; these have been a cause of over agricultural use. These increased storms would not cause many problems but now they can ...
...: The data shows that if there is minimal or extreme acidification in water then oceanic life will be experiencing severe stress. The findings show that my hypothesis was proven correct. Due to this project being a mini projection of the entire ocean it is clear that if humans continue adding chemicals into the ocean then the acidification will rise putting unwanted stress to the fish.
This event resulted in an outbreak of coral disease and macro algae, ultimately reducing reef quality.

Tides are common features of the ocean. Tides occur when large bodies water rise and fall, because of the gravitational pull of the moon and the sun. Spring tides are especially strong tides; in spite of the name they have nothing to do with the season spring. They occur when the Earth, the sun, and the moon are in a line. Spring tides occur during the full moon and the new moon. Neap tides are especially weak tides. They occur when the gravitational forces of the moon and the sun are perpendicular to one another. When water moves from side to side, it is called a current. Currents move warm and cold water to different parts of the ocean.

Thermal pollution is harmful to aquatic ecosystems. They are caused when cool river water are drawn from the water source, run through a power plant, and then discharged back into the same source. This now heated water causes all kinds of mischief and damages to the health of the organisms in the aquatic environment and the environment itself. In an experiment, Gisela Lannig and Inna Sokolova of the University of North Carolina in Charlotte incubated oysters at one of three temperatures, 20°C, 24°C, and 28°C. The differing temperatures of the environment each group of oysters are exposed to in the incubator simulate thermal pollution in the oysters’ natural habitat. What they found was that "the rate of oxygen use, which can be an indicator of physical stress, was three times as high in oysters kept at the warmest temperature as it was in those kept at the coolest" (Raloff, 2005). This reveals that their environment could stress aquatic organisms with just a minute change in the temperature of the ecosystem. This stress could cause the health of an organism to deteriorate or even possibly death.
