Dr. Riegl and Dr. Purkis complete this experiment related to coral reefs and the dynamics of them in a mass mortality event. In the Middle East where this experiment was done over the course of four years from 2009-2012, and took into account four different species and how they responded to these cataclysmic events. The event that took place in 2009 was a series of diseases that severely impacted the coral dynamics, while the next three years of the experiment, mass mortality was caused by bleaching and other diseases. The bleaching incidents seem to be caused by the continual rise of ocean temperatures, and since the corals are being subjected to these types of conditions, they are being exposed to other diseases since they are not healthy. When looking at the hypothesis, the methods, and the results they seem to be supported by the data but this is a biased study. Even though this study may be biased this can have lasting impacts on the environment in the future.
To start, Dr. Riegl and Dr. Purkis start off this paper with background of the experiment of what they did in this experiment out in the Persian Gulf and how this also occurring in the Caribbean and Pacific Ocean reefs as well and how this can be devastating. In the introduction of the paper they state their hypothesis which is that “rising global temperatures and alterations in nutrient dynamics are predicted to further increase the frequency of coral bleaching and mortality events that have already increased dramatically since 1980s” (Riegl and Purkis, 3996). When looking at this hypothesis, the experiment seems to be a continuation of previous experiments that have shown that rising temperatures and nutrients alterations have caused events like this in the past.

... in coral reef systems and their dynamics. They are also able to find how fertile and the coral cover over the course of this four year study through the use of the LTRE and the SsD. Even though this may not tell us the whole story of the coral reef systems, it gives us a good grasp on what we should do to fix it. This article also relates to issues in the world such as global climate change which is very crucial to our survival, which we close up the hole in the ozone and layer and stop the pollution of the oceans causing mass mortality in coral reefs. Without coral reefs we would lose large amounts of aquatic biodiversity and resources, which need to be protected. This study also it relevant to class material as we have learned about the delicate coral reef systems and their interdependence on one another through competition of resources and a stable environment.

Coral Reefs: At Risk Essay

- Coral reefs are diverse ecosystems that emanate great beauty while providing a home to many marine inhabitants. Coral reefs, being a marine ecosystem, are extremely important for the overall health of the surrounding environment. They provide food and shelter to a large bio-diverse population. Coral reefs are among the world’s oldest, most diverse, and most productive ecosystems (Miller and Hackett 129). Coral reefs are found in shallow coastal regions of warm tropical and subtropical oceans. Coral reefs are formed by massive colonies of tiny animals called polyps....   [tags: Ecology ]

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]

Essay on Coral Reefs : A Study Conducted By Bernhard Riegl And Sam Purkis

- Coral Reefs. These amazing organisms play a huge role in the lives of millions of people, as well as on countless species of animals and plants, in more ways than one might imagine. They serve to protect coastlines from major storms, they provide shelter to countless species of fish and aquatic vegetation, and they help to bolster economies in areas surrounding them as tourist attractions. Is coral incredible. Yes. Is it invincible. No. A study conducted by Bernhard Riegl and Sam Purkis serves to demonstrate the fragility of these coral reefs, not only studied, but also, coral reefs around the world; as well as to call into question the actions of society and their effects on the environment...   [tags: Coral reef, Coral, Algae, Population]

Ocean Acidification and Its Effect on Climate Change Essay

- Ocean acidification is one of the highest environmental concerns that involve the change in climate. Ocean acidification is caused by uptake of rising atmospheric CO2. This increase in CO2 is from burning fossil fuels. Not only does it affect humans it affects numerous marine ecosystems. Coral reefs are one of the most affected systems by ocean acidification. Coral is one of the main ecosystem engineers in these ecosystems without them; the ecosystem will not be as healthy or sustainable for other organisms....   [tags: fossil fuels, biodiversity, coral reefs]

Coral Reefs: A Diverse Ecosystem Essay

- Coral reefs are one of the oldest and the most diverse ecosystems in the planet; because of such matter, scientists coined coral reefs as ‘rainforests of the sea. The National Oceanic and Atmospheric Administration or NOAA for short (2008) estimated that about 25% of marine life use coral reefs as safe havens from predators, breeding grounds, and feeding grounds despite the fact that coral reefs only cover a small percentage (estimated about 0.1%) of the world’s oceans. It serves an umbrella specie because it serves both as a habitat and a living, breathing organism for other marine animals to thrive....   [tags: coral reefs, ecosystem, marine life]

Anthropogenic Effects on Coral Reefs Essay

- Abstract: Humans have a very large effect on the ecosystems of coral reefs. Sensitivity of coral reefs causes them to be more susceptible to harmful anthropogenic practices. Some of these are sedimentation, global warming, recreational activities, poison fishing, blast fishing practices, water pollution, and coral mining. All of these very different practices can effectively end up with the same results; the mortality of coral reefs around the world. Coral reefs are an important ecosystem of the world, and support many different industries and millions of people....   [tags: Unprecedented Stresses to Coral Reefs]

Essay about Analysis of Structure and Distribution of Coral Reefs

- The modern understanding of coral reefs begins in Charles Darwin’s book, On the Structure and Distribution of Coral Reefs. In this classic book written in 1842, he distinguished three main types of reef: the fringing reef, the barrier reef, and the atoll. The fringing reef occurs near the shoreline and basically follows the profile of the shore. Its stony corals need a firm base on which to establish themselves, and they must compete with many other sedimentary organisms looking for a firm substrate on which to settle....   [tags: Coral Reefs Structure]

Essay about The Coral Reefs

- There are many diverse plant communities in south Florida, but some of the most enigmatic plant communities are found underwater. The coral reefs are a landscape that many people have not had much contact with. Much like how only the elite, travelling, or industrial entities have a view from the ocean, the coral reefs are only viewed by the adventurous or lucky few that can reach their subterranean habitat. But just because they are not seen from the surface does not mean they should be hard to get to....   [tags: Coral reef, Coral, Primary production, Algae]
