Coral bleaching Essays

Corals reefs are known as the “home” for most of the marine species. They are variety of biological community found underwater strengthened by an organic compound, calcium carbonate, excreted by corals. Though most of the marine ecosystems are consist of massive and diverse population of coral reefs, they are still considered as delicate ecosystems, especially on various conditions. When they are stressed due to constant change of conditions like temperature,they yield a negative outcome called coral

Coral reefs are the most diverse communities in the marine environment. Hermatypic-corals help form the structure of coral reefs and a shelter for a variety of organisms. Living coral reefs form land, provide the sand that lines tropical beaches, and the structures which prevent the waves from causing extensive coastal erosion. However, pollution from sewage and agricultural practices damages corals as well as the wide variety of organisms living within them. Stress is a physiological condition

The coral bleaching phenomenon is occurring all over the world’s coral reefs and it is still happening right knows without we even noticing it. Various approaches have been applied to save this extraordinary God-given structure before it vanishes completely from the earth. However, the world probably should be more concern on the main issues that leads to this problem in the first place. Three major factors that contribute to coral bleaching include the rise in ocean temperature, changes in salinity

It was one of the most disgusting sights I’ve ever seen,” he says. “The hard corals were dead and covered in algae, looking like they’ve been dead for years. The soft corals were still dying and the flesh of the animals was decomposing and dripping off the reef structure” (Slezak). This isn’t the sight most people would imagine when visiting the Great Barrier Reef but it is the new normal with almost 90% of the coral in the GBR containing this look (McKirdy). Instead of the previous vibrant colors

Coral Bleaching is caused when elevated seawater temperatures result in extensive coral loss. When the water becomes too warm coral will expel the algae living in their tissue, causing the coral to turn completely white. Pollution from urban or agricultural run-offs, sedimentation from undersea activity like dredging, and changes in the salinity are other contributors to coral bleaching. Although coral can survive the bleaching they are under more stress and are

How are coral reefs formed? Coral reefs are formed by floating coral larvae that attach to rocks that have already been placed in the ocean or any other hard surface. These then grow along the edges of islands or continents. There three different types of reefs. There is barrier, fringing, and atoll. Barrier reefs border shorelines, but at a greater distance. They are separated from their land mass by a lagoon of open, deep water. Fringing reefs are the most common out of all of the reefs. These

The Cultural Effects of Coral Bleaching Located in warm, shallow waters, one species is near it’s extinction. Scientific studies has anticipated this for years, but many people do not understand the _damage this obsolescence would have on the environment. An essential animal in the ocean, coral, is, “home to 25% of all marine fish species,” according to The Reef Resilience Network, which specializes in helping save coral. Corals have very special tolerances to things like temperatures, salinity levels

Coral bleaching is not just a national problem that Australia faces alone. In the last year (2015), 12 percent of the world’s coral reefs have bleached (Howard). Since the Great Barrier Reef is the world’s largest reef, covering 133,000 square miles, and stretching 1,200 miles along the coast of Australia, it poses an incredible threat to Australia’s economy and environment (Howard). Coral bleaching is not an issue that is often plastered all over the news or brought to people’s attention often.

Australia has had a tremendous bleaching event which has affected the coral reefs and marine life. Around the 1990’s to present time scientists that live in the United States have travelled to the coast of Australia to find out why global warming is happening in these areas. This reef is one of the natural wonders being uniquely seen from the Earth's orbit.The rising temperatures in of the water has impacted about 1,400 miles of ecosystem including marine life and coral reefs. Along with about 1.6

of marine life in coal rees has decreased significantly. Currently, it’s like an underwater desert. Coral bleaching has been around for a long time. However, it is more in the recent years the the issue has become so impactful. Now is the time to work towards a solution for coral bleaching before the reefs die, erode, and are gone forever. Scientists have been researching the effect coral bleaching has on marine life, the ecosystem, tourism and the economy. Due to the amount of non-biodegradable

View of Coral Bleaching Coral bleaching events have become severe issue in the past twenty years. The increase in water temperatures due to climate change and the increased pollution by humans are some of the main causes of increased coral bleaching events. Coral bleaching is the whitening of the coral due to increased stress. The bleaching process causes the coral to have an increased susceptibility to infections and other external factors. This leads to the ultimate death of the coral and the

The event of coral bleaching was executed and monitored under Coral Bleaching Response Plan developed from Climate Change Group at the Great Barrier Reef Marine Park Authority (GBRMPA) by Australian and Queensland Governments. There were four mechanisms constituted in the plan namely system of early warning, response to incident, actions of management, and strategy of communication (GBRMPA, 2010). First Components in Coral Bleaching Response Plan: Early Warning System In this steps of the response

The communicative tools professionals within the different sectors utilise, influence the discourse within the public sphere. This idea is established when analysing the contemporary media issue regarding the coral bleaching occurring on the Great Barrier Reef caused by the changing climatic conditions and human interaction with the reef. Public communication through verbal or non-verbal means has enabled individuals to convey a range of messages to one another with this exchange allowing for the

Abstract Belize’s coral reef is a beautiful ecosystem, comprising of approximately 500 species of fish. It is one of the largest reefs in the world, second to Australia’s Great Barrier Reef. The reef serves as a natural break from water waves. In 1998, two seemingly unrelated events occurred that destroyed Belize’s coral reef. In November, Hurricane Mitch, blew in and tore away part of the reef leaving behind some corals, known as the “standing dead”. After that, El Niño came along and brought warmer

Title The Loss of Coral Coverage due to Nutrient Rich Water Introduction (500 words) This report will explore the global issue of an increase in nutrient richness in coral reefs and the impacts this has had to coral coverage. Coral reefs play a vital part in marine life as they home an abundance of marine wildlife. They attract such a vast population because of their coral seabeds which provide food for a great deal of marine wildlife. Records show that there are 128 documented corallivorous species

the ocean are many different types of corals, but located along the foot of the Caribbean Sea and Gulf of Mexico lies the Meandrina. The Meandrina is a coral that can form spherical heads along with flat plates that extend for yards beneath the sea. Within the genus of Meandrina you have the meandrites. Meandrites are sometimes known as the “maze coral” this type of Meandrina is found on the slopes underneath the water in the common areas for this genus of coral. Most of the formations are hemispherical

Coral Reefs are important to our society because they support bustling diverse ecosystems that provide shelter to a fourth of all identified marine species and act as natural barriers, which protect the coastline from the ocean’s pounding waves. Coral reef ecosystems help to benefit economies by providing protection against erosion, cultivating fisheries, creating and sustaining tourism activities, offering substances for medical uses, and providing a diversity of culture and aesthetics to communities

the effects it has with its symbiotic relationship with Coral Reefs Introduction Coral reefs are among the most riches ecosystems on Earth. Coral reefs only cover less than two percent of the ocean surface (Fujise 2014). Within these coral reefs, corals have a coevolutionary relationship with zooxanthellae. Coral reefs rely heavily on zooxanthellae for photosynthetic byproducts that are required for calcium carbonate production for the corals to grow. Zooxanthellae, specifically Symbiodinium, are

Understanding the Problem at Hand: Coral Reefs It is important for people worldwide to learn of the importance of the coral reefs and of the negative effects that unrestricted tourism and global warming have been causing to them. To clearly see the big picture, one must first go back to see the early roots of the problem. Coral reefs have been being mapped out as early as some of the first maritime sailors, and soon turned out to be a huge destination for tourism. Unregulated tourism is almost

It is important that coral reefs recover once they have been damaged, some of the consequences are; less diverse reef communities, decline in fisheries, tourism and coastal protection (Hoegh-Guldberg et al, 2007). There are 5 potential predictors for how well a coral reef will recover after bleaching (Graham, Nash & Kool, 2011). Firstly, the reef characteristic, if the skeleton of the reef is still present it is likely to maintain ecological processes and therefore recover rapidly (Graham, Nash &
