The Red Tide
The Red is a 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 fish because the fish cant absorb the toxins and survive like the shellfish and ,because of the toxins theres a ginormous amount of fish that are killed by the toxins and there lifless bodys will be floating all the way to the beach and if a bird trys to eat it they can also die from the poisining .
The Red Tides occur can occur from human actions from agricultural runoff. Agricultural runoff can help the Red Tides can form because they are full of nitrates that will grow phytoplankton. Phytoplankton are single celled organisms that are plant-like organisms that can form dense, visible patches near the water's surface. And when they are in a high concentration area they can produce toxins that can paralyze . They can also change colors from either brown to green to red. Another way that the Red Tides can occur from humans is global warming (which humans have increased drastically since 1970). Global warming has increased sea level temperature which in turn will increase the number of phytoplankton and in turn can increase the Red Tide.
The Red Tide can not only occur from human actions but can also occur from natural phenomenons. For example the desert winds carry iron rich sand in bodies of water wh...

...ence of the Red Tide is in January 2013 a red tide bloom happened at Sarasota beach fortunately no one was killed except for fish and some people had respiratory problems.
To conclude, the Red Tide is formed by the concentration of phytoplankton in a area. The bloom can kill you or cause you respiratory problems if you eat the affect fish or stay in the area for a long time. The Red Tide can both occur naturally and man made. It can form man made from global warming ( Which is caused by air pollution) . Agricultural pollution ( which is when fertilized soil goes into the water), and naturally from the desert and El Nino events and desert sands. In order to lessen the frequency or try to stop it people have to pollute less to lessen the frequency of it and also to report any signs of the Red Tide because if you do the authority's will come and secure the area.

As certain types of pollution damages our atmosphere, our natural protection from the sun weakens and as a result the Earth gets warmer with time, impacting the temperature of our seas. The unfortunate results of global warming and the co...
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 now ruining Australian fishing industries by taking over the ocean. Scientist Judith O’Neil from the University of Queensland was the first scientist to discover the origins of this toxic algae. It has been considered a fireweed since it has severely affected ecosystems all over the ocean and has been dominating. However this is not the only primitive species if ocean plant taking over rapidly now. It has been stated that, “Evolution is in reverse” (Kenneth R. Weiss from the Los Angeles Times). Now ancient species of sea life are thriving while more complex organisms and new species aren’t thriving in our oceans. That situation is bad since they are taking over ecosystems completely blocking animals from sunlight, space, and any other necessities. There have also been other species that are now plaguing our oceans such as jellyfish, and other species of algae. These organisms can definitely lead to negative impacts on us and the ocean’s vast ecosystems.

Leading scientists advise climate change will cause increases to the frequency and intensity of extreme weather events. Rising sea levels pose a significant risk to coastal communities, while the world’s oceans could become too acidic to support coral reefs and other calcifying marine organisms. Coral reefs contain only six per cent of the area of the Great Barrier Reef, yet they provide critical habitat and food for numerous species in the ecosystem. However, climate change has already impacted coral reefs in the Great Barrier Reef as corals are very helpless against its potential impacts. Eight mass coral bleaching events has occurred since 1979, triggered by unusually high water temperatures. And because of this, zooxanthellae (photosynthetic algae) leave their tissues and corals will have no more colours hence ‘bleaching’. Without the zooxanthellae, the corals that remain gradually starve to death. Once the coral dies, fish and a multitude of other marine species are soon affected. Rising sea levels and more frequent and intense storm surges will see more erosion of Australia’s coastline, causing community and residential
The Sun’s radiation heats the upper atmosphere, sending the energy toward the earth’s surface and finally mixes with the planet’s counter-rotational currents, creating jetstream flows. The winds flow over the ocean’s surface creating friction that spawns chops, pushing up the seas forming perfect bands of open ocean swell. Pushed on by gravitational forces, the swells speed away from the winds that they came from, moving across the deeps until they feel the drag of the shallows near the coast. As the swells rise up out of themselves, they peak, curling into the liquid dreams that we surfers ride (Kampton 4).
The beginning of the industrial revolution resulted in an increase in the amount of anthropogenic carbon dioxide (CO2) released into the atmosphere due to an increase in industrial and agricultural productions. The ocean absorbs approximately 32% of the CO2 that is released from burning fossil fuels into the atmosphere each year, and thus the dramatic increase in atmospheric CO2 is coupled with an equally drastic increase of CO2 absorbed by the ocean. Ocean acidification is simply the process of the chemical change in seawater caused by the absorption of CO2 (Schlesinger & Bernhardt, 1997).

Red tides have made many people sick such as residents and tourists of Florida’s Gulf Coast. The tides also have affected many business owners because many tourists don’t want to come to beach resorts because of Red tides. Red tides are caused by two ways. One of the ways are the algae reproducing and giving an effect of toxic air. Many outbreaks have also occurred because of red tides. Such of these things include poising form fish and shellfish. To stop Red tides, many researchers have done numerous experiments to try to find a way a way to stop Red tides! There are three main solutions to stopping Red tides. If we try to do these solutions red tides will decrease in the amount of times they occur.
Surfers, swimmers and sunbathers use beaches for recreation. People fish off beaches for food. Since many people take their vacations at the beach, lots of beaches in tropical locations are important to their country’s economy. Entire cities, regions and countries depend on the money tourists spend while visiting the beach. Beaches are naturally very dynamic places, but people try to control them and build permanent structures, such as houses, restaurants, shops and hotels, on or near the shore. The natural erosion and deposition of beaches becomes a problem. Beaches con disappear over time, or even over night during severe storms. Beaches are areas of loose sediment (sand, gravel, cobbles) controlled by ocean processes. Most beaches have several characteristic features. First are offshore bars, which help protect beaches from erosion. Next is the foreshore, which rises from the water toward the crest of the next feature; a berm. On low-lying shores, dunes form behind beaches. Dunes look like rolling hills of sand and are blown into place by the wind. New, smaller dunes are often changing shape as the wind continues to affect them. Waves and currents move the accumulated sediment constantly creating, eroding and changing the coastlines.
Abiotic factors are things that are nonliving that influence an environment and it's inhabitants. Some of the abiotic factors that are attributed to coastal erosion in Louisiana are hurricanes, tropical storms, elevation, sunlight, overnutrition, sea-level rise, and deposition. Hurricanes bring about larger waves which cause dune erosion or beach erosion (Clark et al., 1998). This is significant because beaches and/or the dunes of the beach serve as buffers to the coastline and the ecosystem. As the beach or dunes recede from the erosion caused by these large waves and an increased sea-level the flora and fauna that help sustain the area die off or retreat to a more habitable zone leaving the wetlands in a critical state often resulting in a total loss of the area (Stockdon et al., 2012). Due to the nature of the Gulf of Mexico large destructive storms such as hurricanes or tropica...
?The Eagle has landed.? Many people use this phrase without knowing where it came from. On July 20, 1969, NASA astonished the world, when Neil Armstrong spoke these words when the Apollo spacecraft, nicknamed ?the Eagle,? landed on the moon?s surface. He later spoke the famous words, ?One small step for man, one giant leap for mankind,? when he was the first man to set foot on the moon. When astronauts walk on the moon, they are allowed to breathe, because of their space suits. These space suits have oxygen tanks in them, and allow astronauts to stay out in space for up to seven hours at a time. They have to think ahead a few steps so they can step or turn without difficulty, because they have to take huge steps. The pull of gravity on the moon is one-sixth lower than the pull of gravity on the Earth, which makes them a lot lighter on the moon. The moon?s gravitational pull controls the ocean?s tides on the Earth. The moon pulls the Earth and water towards it, which causes an increase of water nearest the moon. As the moon pulls the core of the Earth towards it, the water on the side farthest away from the moon flings around to the side, and creates an increase of water there, too. The increase of water is called a high tide. On the sides of the Earth not facing the sun or moon, there are low tides. Each beach or po...
“The sandy beach is a harsh, constantly changing environment,” explained by the UKMCS (2). This is the ocean is constantly moving because of the wind in the earth’s atmosphere (Crawford 4). Along the edge of most coastlines, a commonly found zone is an estuary (Marine Conservation Society (UK) SouthEast 1). This is where brackish waters, an area where freshwater is released and mixed with the ocean’s salt water, is created (1). However, even though there are small amounts of freshwater added, this does not change that the salinity of the ocean is remarkably high.
The leading natural cause of destruction among the coral reefs is global warming. Global warming causes the bleaching of coral reefs to occur. Bleaching is a response to stress by the coral reef that happens when the water becomes to warm. The coral then put out a brownish zooxanthelle which causes them to lose their color. Without the zooxanthelle, the corals cannot provide nourishment for itself and th...
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.
