Fresh and saltwater are both dependent upon algae for both oxygen production and the fact that algae offer a source of sustenance for many zooplankton and small species of fish. However, there are many types of algae that are detrimental to marine ecosystems. Especially when an algal bloom occurs, or when algae reproduce extremely fast. An algal bloom can exhaust oxygen stores and obstruct the sunlight needed by other organisms to stay alive. Certain forms of algal blooms may generate dangerous toxins in the waters in which they live. One type of algae that produces harmful toxins is blue green algae. These archaic, microscopic organisms are referred to as cyanobacteria, as they are a type of bacteria. (WHO, water-related diseases, 2014). Cyanobacteria may be present in any body of water such as lakes, ponds, creeks, or even oceans. Often, the bacteria are more prevalent in slow moving, warm waters and are most frequently observed during the late summer and early fall seasons. The algae may or may not be apparent on top of the water. If it is perceptible, it appears like foam or scum in a blue, green, red, or brown color. As the blue green algae blooms expire the water can have a rotten-egg like smell. (EPA, Climate Changes and Harmful Algal Blooms (n.d.).
Many blue green algae bacteria are poisonous to humans, other mammals, birds, and fish. Contact with these toxic bacteria can cause a multitude of symptoms in humans. Depending on the nature of the exposure, different symptoms may result. For instance, contact with the bacteria topically via the skin can produce rashes, hives, or skin blisters. Toxins that have been inhaled can cause respiratory, allergic, or asthma symptoms including cough and sore throat, also headache, and r...

...tributing factor to the increase in harmful algae blooms. Climate changes and nutrient pollution are due to excess nitrogen and phosphorus being made available via runoff into water bodies. This excess in nitrogen and phosphorus propel the growth of blue green algae at rate that the marine environment is unable to keep up with. (EPA, Climate Changes and Harmful Algal Blooms (n.d.).) Scientists are in the process of researching ways to monitor and decrease nitrogen and phosphorus levels in water. Ways to help decrease nutrient pollution include avoiding use of excess lawn fertilizer, use of phosphorus-free fertilizer, attempting to not apply fertilizer where the runoff has direct contact with storm drains, and preserving natural foliage along the shoreline as this aids in filtering water and does not require fertilizer to survive. (WHO, water-related diseases, 2014)

The Effects Of Thermal Pollution On The Marine Life And Local Ecosystems

- Thermal pollution can be simply explained as the addition of surplus heat to water and ejecting it back to the water bodies. So how does it happen. Well, numerous industries take water from natural water resources for their industrial purposes. Maximum of this water is used as coolant as it is used to cool down the machines of any factory or plant. Afterwards, this used water with altered and much high temperature is ejected back to the natural resources including lakes, ponds, seas, etc. This causes sudden increase in temperature of natural water bodies too....   [tags: Water, Water pollution, Water resources, Heat]

The Effect Of Nutrient Loading On Natural Pathways Of Ecosystems Essay

- Introduction Eutrophication is a widespread matter of concern affecting estuaries and other coastal ecosystems, and detrimental to coastal and marine species (Gray, Wu & Or 2002; Bricker et al. 2008). Gray, Wu and Or (2002) describe the eutrophication process as an increase in different nutrient levels resulting in creation of both dissolved and particles of organic substance which ultimately leads to decrease in level of oxygen concentrations due to decaying or degeneration of those organic substances....   [tags: Water pollution, Eutrophication, Soil, Oxygen]

The Origins of a Newly Formed Toxic Algae in the Ocean Essay

- 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....   [tags: fireweed, ecosystem, jellyfish]

Carbon Sinks In the Oceans Analysis Essay

- Carbon sinks are found when there is a collection of carbon dioxide within a reservoir. Both, the terrestrial and aquatic systems, can act as natural carbon sinks, as can the atmosphere, where the collections of carbon dioxide as well as carbon dioxide emissions are high. The efficiency of these sinks has been declining since the 1990’s (Canadell et al. 2007). Approximately, 50% of carbon dioxide emissions are collected in the terrestrial and oceanic sinks (Ritschard 1992), which are detrimental to the ecosystem....   [tags: greenhouse gas, carbon dioxide, ecosystems]

Marine Ecosystems: Coral Reefs Essay

- Declan de Mamiel (1033575) Coral reefs are the oldest of marine ecosystems, the youngest approximately 10,000 years old, and are often referred to as the rain forests’ of the ocean. Found commonly in tropical waters less than deep, these areas have a high availability of nutrients and access to sunlight required for the process of photosynthesis. Coral reefs are amongst the most complex and bio-diverse ecosystems, spanning approximately 284,300 km2 (Spalding & Ravilious et al., 2001) providing a home for 25% of all marine life....   [tags: marine environment, oceans, global temperatures]

The Value Of Coral Reefs Essay

- Value of Coral Reefs The variety of biodiversity present on coral reefs is greater than in any other marine ecosystem despite reefs being present on only 0.1% of the world’s oceans. Of the 33 phyla present on Earth, 32 of them can be found on coral reefs and 15 of the 32 are found exclusively in coral reef ecosystems (Bryant et al., 1998). These ecosystems represent essential spawning, nursery, and feeding grounds for over 25% of total marine biodiversity (Bryant et al., 1998). Twelve percent of all marine fisheries are directly or indirectly reliant on coral reef ecosystems in addition to over 4,000 species of fish, an abundance of macrofauna (e.g....   [tags: Coral reef, Coral, Ecosystem, Algae]

Essay about Oil Spills: Effect on Wildlife

- Almost every year ocean wildlife, birds and other animals are killed or seriously injured due to tanker ship oil spills that could be prevented. Oil spills happen mainly due to captain and crew errors. As they travel across the ocean they become careless, non-observant, and make simple mistakes that cost millions of dollars as well as the lives and habitats of animals in the area and farther. Although, there are many other reasons for oil spills such as weather conditions, illegal dumping, countries at war or terrorists attempting to get a countries attention....   [tags: Ocean Wildlife, Birds, Animals, Oil Spills]
