Great Barrier Reef Change

Improved Essays
A one-of-a-kind place, the Great Barrier Reef located off the coast of Queensland in northeastern Australia, is the largest living thing on Earth. Stretching over 2300km, this largest marine park reserve covers 348,700 square kilometers. Many breathtaking marine creatures call the Great Barrier Reef home including 600 types of soft and hard corals, more than 100 species of jellyfish, 3000 varieties of mollusks, 500 species of worms, 1625 types of fish, 133 varieties of sharks and rays, and more than 30 species of whales and dolphins. Although most marine reserve parks are set up as strict preservation areas, the Great Barrier Reef is unique because it is a multiple use protected area. Protecting the natural area is most important, but a diverse …show more content…
This means there is not enough carbonate or calcium carbonate which forms shells and skeletons dramatically decreasing the coral’s reproduction (3). This problem began with the start of the industrial revolution when increases in industrial and agricultural activities caused more carbon dioxide to be released into the atmosphere (2). The absorption of carbon dioxide by our oceans is leading to chemical changes to the oceans. The most notable is ocean acidity levels increasing from 8.1 to 8.2 (WHAT) (?). While an increase of .1 might not sound like a big deal, it is because reef development is expected to cease at 7.8 according to David Wachenfeld, director of reef recovery at the Great Barrier Reef Marine Park Authority. Ocean acidification is commonly the most significant impact of a changing climate onthe Great Barrier Reef ecosystem (3). The change in ocean acidification is weakening coral reefs around the world, making them more vulnerable to impacts of ocean warming and water pollution (1). The scientists concluded in the paper that their findings, combined with projected ongoing warming, show that even if rates of climate pollution are reigned in, that “may not be sufficient to avoid significant impacts” of acidification on coral reef regeneration. According to Wachenfeld, this latest researchunderlines the fact that the single biggest thing we can do to protect the Reef for the future is to greatly reduce greenhouse gas emissions as …show more content…
However, the future of the group that produced the paper is in question because the Australian government announced that it plans to cut 90 or more jobs from CSIRO’s ocean and atmosphere division, leaving as few as 30 staff remaining. The threatened job cuts make it unclear whether its plans for projecting future conditions at the reefs will move forward. These future models could give scientists the ability tounderstand long-term impact of ocean acidification on the coral reefs and a better understanding of how they might save the beautiful reefs from

    Elizabeth Kolbert’s book, The Sixth Extinction, covers the argument that we are currently in another mass extinction because the Earth is following similar trends as it did in the past five mass extinctions. The first chapter of The Sixth Extinction starts out by discussing frogs. Frogs are the one of the oldest species on Earth; however, the extinction rates of frogs is higher than it’s ever been, and it’s only increasing. Kolbert then focused specifically on Panamanian golden frogs. Not too long ago, these frogs were plentiful, but recently the numbers have decreased due to human’s introducing a native species to Panama: Chytrid fungus.…

    Coral reefs provide shelter and food for more than 1 million plant and animal species, which is nearly one quarter of all known marine species. This number includes over 4,000 species of fish, 700 species of coral, and thousands of other plant and animal forms of life (Cesar, et al.). A single coral reef at its prime contains tens of thousands of species, housing some of the most dense and diverse communities of vertebrate animals in the world. Unfortunately, with the destruction that they face, very few coral reefs still resemble this condition, with corals and fishes less abundant than they were a few decades ago. Since we didn’t start studying coral reefs until they were already degrading, we aren’t sure about the historical biological baseline…

    The Great Barrier Reef (GBR) is found off the northeastern coast of Queensland, Australia, in the Coral Sea of the Pacific Ocean. Scientists believe that the coral reef structure was formed 60,000 years ago, but deteriorated due to climate & sea level changes. However, the coral reefs grew over the old structure. The current GBR is about 6,000 - 8,000 years old. The reef’s abiotic factors include sunlight, soil, water, climate, & temperature.…

    It is also a breeding ground for animals such as six different species of turtles. The great the barrier reef is ancient and to some is dated back to around twenty million years ago. Sadly the great barrier reef is threatened by many things such as climate change, warmer ocean temperatures put stress on coral and lead to coral bleaching. The great barrier reef has experienced two mass coral bleaching events in 1998 and 2002, the bleaching was more severe in 2002, when aerial surveys showed that over more than 50% of the reef experienced coral bleaching. Sediment, nutrient and agriculture pesticide pollution from river catchment runoff is also affecting the reefs health.…

    Climate change is the greatest global threat to the coral reefs. Mass floral bleaching events and infectious disease outbreaks are happening more often now that the temperatures are rising across the reefs' water, the pH of the water is decreased. This causes the reduction of calcification rates in reef building organisms. Both climate change, and carbon dioxide contribute to these mass bleaching…

    Between 1800 and 1994, the oceans had absorbed around 48 percent of the total amount of carbon dioxide from burning fossil fuels (IPCC, 2014). Therefore, the amount of carbon dioxide absorbed by the ocean would have increased considerably since then, and with the increased production of carbonic acid which releases bicarbonate and hydrogen ions, the amount of carbonate ions which are necessary in the creation of coral shells and skeletons decrease significantly. (Australian Government, n.d.) Therefore, more acidic seawater impacts coral significantly, dissolving their shells and skeletons, and hindering their ability to absorb calcium carbonate. Ocean acidification not only impacts coral and the animals that rely on coral as their main food source, but the animals that make calcium carbonate shells such as snails and clams (How does climate change affect the reefs?,…

    Introduction: Australia’s Great Barrier Reef (GBR), one of the world’s most precious marine ecosystems, has been deteriorating due to poor water quality (Kroon et al., 2016). One of the main reasons for this substantial decline in water quality over recent decades is agricultural runoff of nitrogen, pesticides/ herbicides and sediment (Figure 1). In fact, the water quality is most affected in the inshore areas in the southern and central regions near the most intensive agriculture. The impacts are biophysical in their effects on the marine animal and plants of the Reef. For example, coral cover declined about 50 percent from 1985-2013 (Brodie et al., 2013, p.2).…

    The Great Barrier Reef in Australia supports over half of the hard coral species and one third of the soft coral species in the world; however, the cumulative impact of human activities such as agriculture, mining, and industrial development have caused an estimated 50% loss of coral cover (Grech et al., 2015). Ocean acidification is one of the primary causes of this loss and is arguably one of the most detrimental consequences of climate change on the Great Barrier Reef ecosystem. With increased burning of fossil fuels, more carbon dioxide collects in the atmosphere, increasing the planet’s temperature. Approximately 30% of this carbon dioxide dissolves in the oceans, producing carbonic acid and lowering the pH levels of all oceans (Waters,…
