Knowledge+Saturation

Welcome to our Knowledge Saturation page! We have put up links and videos that we hope you will find useful and learn more about coral bleaching! The below descriptions talk about what kinds of informative imformation the websites or videos include. So be free to check out the sites that are on offer and you may learn a thing or two like we have!

Some facts about corals and coral bleaching:


 * Research on coral bleaching has shown that it is caused by stress to coral. coral is in fact a very delicate organism, adapted to survive in nutrient-poor waters. (i thought coral was hard and tough unlike me =P )
 * Corals tolerate a narrow temperature range between 25 degrees Celsius and 29 degrees Celsius depending on location.
 * There are over 400 species of corals on the Great Barrier Reef. Together they provide the foundations of the greater structure of the Reef.
 * Coral bleaching events have been increasing in frequency over the last 20 years and are predicted to become still more frequent as water temperatures and carbon dioxide levels continue to rise.( hoping it wont happen =/ )

The above link has various types of infomation on coral bleaching. Such as : Importance of coral reefs, Rising sea temperatures and coral bleaching, Rate of coral bleaching and many more. Things that we have learn't from this site - - There are many cause of coral bleaching, some causes include - increased exposure to ultraviolet (U.V) radiation, heat stress (may be known as global warming), large amounts of storm water from heavy rains which lead to flooding of the reef and many more. - Corals are actually animals, they are related to anemones and jellyfish. || media type="youtube" key="WvsaWYFm1_A" height="344" width="425" This is an animation which talks about the effects of coral bleaching and the process. It also talks about what may happen in the future if coral bleaching continues. Things that we have learnt - - Coral reefs are home to 1 in 4 marine fish. - Global warming is suspected to be one of the causes of coral bleaching. - 25% of the earth's coral reefs have already been destroyed by coral bleaching and the rest may be all gone in about the next 50 years. || -From reading this text, we learn't that coral bleaching isn't always done by humans, it can be done by underwater creatures and its also caused by high seawater tempratures. This could be something we could research further on. || media type="youtube" key="XNAoexBmSik" height="344" width="425" This video talks about the process of coral bleaching and the many causes. From this animation we have learnt that - - In recent years, amounts of Co2 (carbon dioxide) have sky rocketed. - Coral has been losing its colour due to high water temperatures. - The most significant cause of coral bleaching is the rise in surface temperature as U.V rays hit the oceans surface they increase the temperature of the water, the coral experiences extreme stress as a result of the heat, the coral releases zooxanthellae which then leads to the coral changing to a white colour. || From looking at this website, we have learnt that - -Coral bleaching is a stress condition that occurs in corals. -Corals can die due to high stress conditions ||  || Coral reefs have been evolving for millions and millions of years. This is one reason for all their biodiversity. But in just a decade or so we﻿ have disrupted the evolutionary patterns that established over eons. Also interesting: the effect of eutrophication on the reefs. As significant as the other perturbations. Have you ever dreamed that your on the Great Barrier Reef?Snorkelling around the corals?Well think again cause the humans(us) are polluting it.Rising sea levels,earth heating up... || We learnt: Earthwatch scientist Dr. James Crabbe discusses the cause of coral bleaching and how it impacts the stability of reefs! || This game is a game from [|facebook.com]. So you will need to have an account on that to play the game. The game is basically about saving the corals and the reef. It teaches you a lot about it and how you could keep it safe. It also contributes to [|SaveNature.org] and raises money for the Center for Ecosystem Survival charity.Funds will be used for the conservation of threatened and endangered coral reefs and their surrounding marine ecosystems around the world. || || The above link is about the corals dying and why they're dying. Things we learn t from looking at this website: -Nearly 600 square miles of reef have disappeared each year. ||  ||
