Anthropogenic activity has affected a large number of ecosystems in the world including the earth’s oceans. Atmospheric levels of carbon dioxide (CO2) have been escalating since the rise of the industrial revolution and are now at a far more prominent rate than previously experienced in the Earth's history primarily due to the burning of fossil fuels (Wood et al., 2008). The concentration of CO2 in the Earth's atmosphere now surpasses 380 parts per million (ppm), which is more than 80 ppm over the
also ponder the ramifications of our past, present, and future Fertilizing the Ocean: adding iron, sequestering carbon The ocean is a massive carbon repository. Scientists looking combat global warming thought that carbon from the atmosphere could be moved into the oceans, where it would stay for millennia. The man accredited for this idea is the late John Martin, who discovered that in many regions of the ocean, iron has been found to be the limiting nutrient for growth (NASA). Iron, a macronutrient
World Beneath the Waves For human beings,the oceans are closely linked to human's life. We can't imagine that in the boundless blue earth,its biological resources,mineral,renewable energy and space etc. It brings to our life value is immeasurable. The oceans are the home of rain,the cradle of life,the treasure-house of resources,the"second space" of human existence and development. The author divided the text into four parts. Almost three-fourths of earth's surface is covered with oceans.Oceans
Our Oceans are a vital bloodline carrying humans, water, and different types of animals and plants. Now more than ever our oceans are in peril due to the disastrous effects of Ocean Acidification. According to, NOAA Director Dr. Jane Lubchenco (2016), “Ocean Acidification is often referred to as global warming’s equally evil twin” (The Osprey pg.1). Ocean Acidification is an issue that the general public knows very little about yet is just as dangerous. Our Oceans are like a gigantic beaker with
branch of Earth science that studies the ocean. It covers a wide range of topics, including marine organisms and ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers blend to further knowledge of the world ocean and understanding of processes within it:
Organisational Structure and Culture of the Oceans 11 Team 1.0 Executive Summary: The Department of Trade and Industry (DTI)[1] wished to review how the Ocean’s 11 team was formed and discuss by putting a management development programme together, the organisational behavioural aspects of the group. A vast amount of research was conducted in order to put together the management development programme together to show other organisations how to prevent problems within their group and avoid issues
IOOS: Integrated Ocean Observing System Oceans cover over 70% of our planet, yet very little is known about their biological content, physical systems, and how, both together and individually, they affect our planet. Understanding the affect the ocean has on weather, climate changes, and the ecosystems of the planet are of ever-increasing interest to the human population. Studies, experiments, and more are currently being conducted by various means, sources, and organizations. Due to
million metric tons (MT) of plastic waste was produced in 192 coastal countries in 2010, with as much as 12.7 million MT entering the ocean (Jambeck et al., 2015). Plastic pollution can be classified based on the overall size and thickness, as microdebris (2 µm), mesodebris (1-5 mm), or macrodebris (>20 mm). Plastic can be very harmful to the land, waterways, and the ocean due to its extremely slow biodegrading process, which can exceed hundreds of years. Plastic debris can also be harmful to marine life
today’s oceans are depleted and struggling against overfishing and human influence, while still remaining optimistic about the future of the world’s oceans in his book The Unnatural History of the Sea. Roberts begins by painting a picture of the oceans as they may have been before human influence had drastically depleted species and changed ecosystems through fishing. From this point, he maps out centuries of development in fishing and shows how drastically changed and depleted the world’s oceans are
average temperature to rise to an unparalleled level in human history. The amount of carbon dioxide in the atmosphere, as well as the cyclical processes of the Earth and Sun, affect the warming of our oceans and atmosphere. Although processes other than anthropogenic practices modify the climate, our influence on the climate since the Industrial Revolution has been unmatched. According to the Intergovernmental Panel on Climate Change (IPCC), “Recent climate changes have widespread impacts on human and
