Ocean Analysis : Ocean Dead Zones

The purpose of this research paper is to make more people aware of ocean dead zones and how they can not only affect the marine oasis, but how the can affect us as humans also. Dead zones are a more common term for the word hypoxia, which means lower or reduced levels in the water. Dead zones are areas in oceans and lakes where the oxygen levels are low, too low for most organisms to survive in them. Dead zones are so because of a process called eutrophication. Eutrophication happens when a body

In the article “Oceans of Pollution,” published by Al Jazeera, Dahr Jamail discussed the impacts of pollution on the world’s oceans. He talked about the amount of plastic wastes produced by human and the increasing area of “dead zones.” He showed how seriously plastic debris and chemical fertilisers have affected the environment and how harmful they are to ecosystem. Jamail tried to warn general publics on the damages they have caused on the environment and hoped to gather people’s attention on pollution

Imagine walking along the beach in Hawaii and as you walk among a group of rocks that are coming out of the ocean you notice a sea turtle sunbathing. This is not a good place to snorkel or swim, but as it turns out it is a great place for turtles to sunbathe and eat near the rocks. As you watch the sea turtle turn around and scoot into the ocean, you wade in after it, snapping picture after picture as a bale of turtles came towards you. Suddenly you are surrounded by at least ten turtles all rubbing

Pollution Effects on Pelagic and Benthic Areas of the Ocean Biodiversity refers the existing variations present which form an ecosystem enabling human survival. However, the alteration of the world habitat has caused a shift in biodiversity. The role of ecologists is to ensure that there is no extinction of various species in the world due to reckless human behaviour. The maritime environment is among the worst hit areas as human activity creates an imbalance in the water levels. Factors such as

This unit is designed to provide opportunities for second grade students to explore and research animals in the ocean, the characteristics and features of the ocean, and how people interact within the ocean habitat in a positive or negative way. Students discover five features of the ocean floor and then create a model of the ocean floor. Students complete a map labeling continents and oceans. After playing a globe toss game and discovering how much of the earth is covered by land and water, students

The ocean in medieval times was a thing of great mystery to the ordinary medieval peasant. However to the explorers, the church and the educated the sea was a dangerous place. The ocean began to fascinate people in the time of the early Greeks. The Titans ruled the earth in the beginning, and Oceanus, son of Uranus and Gaea was one of them. "In him [Oceanus] Homer salutes the essence of all things, even the Gods, and regards him as a divinity whose power was inferior to none but Zeus'" He

The world’s oceans cover 70 percent of the earth’s surface (Allsopp, Page, Johnston, & Santillo, 2009). The oceans biodiversity is increasingly becoming more threatened each year by anthropogenic activities such as pollution, destructive fishing methods, overfishing and commercial agriculture (Tyus, 2012). Marine conservation has improved over the years to protect and preserve ecosystems in oceans and seas. To limit the anthropogenic damage, restore habitats, species and preserve vulnerable marine

2004 Indian Ocean Tsunami 2004 Indian Ocean Tsunami Enormous forces that had been building up deep within the earth for hundreds or perhaps thousands of years were suddenly released on December 26, 2004, unleashing the energy of 475,000 kilotons of TNT or 23,000 Hiroshima-sized atomic bombs. This event would come to be known as the 2004 Indian Ocean Tsunami, and it would result in a death toll of 283,000, the deadliest tsunami in history. This report examines information surrounding how nature

The ocean is one of our most precious natural resources. Every living thing depends on our ocean. The ocean hold 97% of the earth water, as they produce oxygen and absorb carbon. The ocean is a source of food and a natural living habitat for all sea creatures. Over the years as we move closer, the surface of our oceans is beginning to stew up with millions to tons of marine debris, as it has a huge impact on our ecosystem. The oceans are becoming vital for our life and breath and as we are abusing

how abiotic conditions at different tidal heights affect biodiversity at Cranberry Cove, NS. Catherine Robertson B00670867 Abstract The intertidal zone has stressful and fluctuating abiotic conditions, making it harder for species to survive in the environment. It is important to study the intertidal zone as it can help to understand how the ocean is being affected by climate change (Gutowsky 2016). This study was conducted at Cranberry Cove, NS, to investigate how abiotic conditions at different
