Coral Bleaching And Its Effects

Beneath the surface, the ocean is teemed with lot of life rather than any other biodiversity. Corals are the main reason and primary source of life for countless animals. But these reefs have been reached an endangered state because of the human activities. Most of the corals have been wiped out due to pollution, unrealistic fishing activities and climate change.

Due to warm water temperatures, corals reach to a stress sate which results in releasing the algae present in their tissues which makes the coral white. This is referred as coral bleaching, but that doesn't mean the coral is dead. A coral can survive a bleaching event, but if the water warms more it results in the dead of the coral.

In 2005, most of the corals have been died due to extreme bleaching event. This thermal stress is much greater than compared in all the 20 years.

Not only warm waters, even cold waters can result to bleaching. In 2010, cool waters in Florida have been made some serious damage to the coral which cause them dead. The water temperatures have been dropped to 12 degrees which is lower than the typical temperatures.

Coral reefs are the rich ecosystem on the earth. Most of the just know them as home décor and jewelry. But doesn't know that they are made of living things and most of the world doesn't even know they are at threatened stage. It takes decades or even longer to create reef structures. They are the rich source of life and they need to be protected.

Sea Turtles: The Endangered Species

Image
Sea Turtles have outlived almost all the prehistoric animals once they shared the planet. Marine turtles inhabit the oceans open waters and coastal habitats, feeding on jellyfish and other aquatic plants and animals. They are the live representatives of a group of reptiles that traveled our sea for more than 100 million years.  Importance of Sea Turtles These sea turtles have been living for more than 100 million years and maintaining a fundamental link in the marine ecosystem. They maintain the health of seagrass beds and coral reefs that benefit the valuable species such as lobster, shrimp, and tuna. Having outlived million years they can hold their breath up to five hours. They also transfer the vital nutrients from oceans to beaches and dunes. The seven extant species are The Green, Loggerhead, Kemp's Ridley, Olive Ridley, Hawksbill, Flatback, and Leatherback, which are endangered. Five of the seven species are found in tropical and subtropical waters. The other two sp...

What Gives More Oxygen on Planet Earth?

Image
Everybody knows that plants and trees produce oxygen for the earth. But, do you know that oceans and seas contribute more oxygen. Produced by marine plants, algae and single-celled organisms called phytoplankton. These may not be seen by the naked eye but produce more, which is not even close to the proportions produced by the trees and plants. The ocean produces oxygen as a by-product of photosynthesis, which converts sunlight and carbon dioxide and can use as energy. One type of plankton, Prochlorococcus releases tons of oxygen into atmosphere. So small, that can millions can be present in a single drop of water. It produces 20% of the oxygen to the earth biosphere, which is more than the rainforests on land combined. Scientists mention that a single cell can give oxygen for one in every 5 breaths we take. Calculating the amounts of oxygen on oceans may vary because of the change in climate conditions, geographic location and with the tides. It is also important to remember that the...

Experiencing Georgia Aquarium

Image
Hey there, I'm Mounika and I'm here to talk about the most magical and engaging place Georgia aquarium  No matter your age, everyone is a kid at Georgia Aquarium . Home to the most amazing aquatic animals, including beluga whales, whale sharks, manta rays, penguins, sea otters, dolphins and many more. Whether it may be dolphin show or sea lion presentation or entering the zone of Predators of the Deep, everything is amazing at Georgia aquarium. Filled with 11 millions gallons of water in seven permanent galleries making home to over 100,000 animals.  The Georgia Aquarium is divided into 7 sections: Coldwater Quest, Ocean Voyager, Tropical Diver, Georgia Explorer, River Scout, Predators of the Deep and Dolphin Tales. Ocean Voyager is the largest exhibit with 100-foot underwater tunnels and one of the largest viewing windows.  There's so much to see in Georgia Aquarium. I spent half a day roaming and getting mesmerized by the amazing creatures. Located in Downtown Atlanta a...
