Hydrothermal vent

Hydrothermal vents are the result of seawater percolating down through fissures in the ocean crust in the vicinity of spreading centers or subduction zones places on Earth where two tectonic plates move away or towards one another in the divergent boundary. Hydrothermal vents are like geysers, or hot springs, on the ocean floor. The discovery happened in 1977, scientists exploring the Galápagos Rift along the mid-ocean ridge in the eastern Pacific noticed a series of temperature spikes in their

Theory of the Origin of Life being Underwater Hydrothermal Vents According to the Bible, God created the first man, Adam, from the soil and the first woman, Eve, from Adam’s rib. These events happened in the Garden of Eden almost six thousand years ago. That is one of the many beliefs of how carbon based life forms, otherwise referred to as living organisms, came to exist on Earth. Since the beginning of man’s reign on earth he has tried to explain his origins. He has used various religions

Hydrothermal vents are cracks in the ocean floor that emit hot water with minerals and bacteria. The first hydrothermal vent was discovered on February 17th, 1977 by geologists on a research expedition in the Galapagos Rift off the coast of South America. The Galapagos is part of the mid- ocean ridge. (1999-2015) The discovery of the hydrothermal vents along the Galapagos Riff led to the identification of chemoautotrophic symbiosis. These vents are widespread along the sea floor. They release sulfide

A natural start to life: Aristotle, a famous philosopher, believed in the notion of spontaneous generation, the idea that life could arise from inanimate objects. Louis Pasteur famously dispelled this theory, when he showed that organisms will only arise if the parental species is initially present in a closed system. However, this conclusion relates to the generation of new organisms from parental ones, not the origin of life itself. The first “organism” had no “parental” species, therefore the

Conner Sheahan Section B06 April 28, 2015 Word Count: Environmental Impacts of Underwater Gold Mining The ocean covers over seventy percent of the Earth’s surface, yet humans know very little about it and its contents. With over half of the species in the ocean still undiscovered, the ocean remains a mystery, with much more to be learned about what it possesses. The ocean is home to not only life, but to natural resources. Some of the resources possessed within the ocean are minerals, such as

Deep Ocean: The truth of the Twenty Thousand Leagues under the Sea Everyone might have once imagined dark environments and scary creatures which live in the deep sea. These childlike dreams are visualized in the popular novel, Twenty Thousand Leagues under the Sea. In the novel, the main character, Pierre Aronnax, searches for a mysterious sea monster while fighting with scary undersea creatures. Although many undersea creatures have been depicted in the novel, one of the striking deep sea creatures

southern part of the arc where the Brothers (site 3) and Rumble II West (site 4) volcanoes are located. Both these volcanoes have large calderas which are associated with hydrothermal activity, and Brothers Volcano has erupted silicic rocks which are also associated with hydrothermal activity (Nichols, 2009 p271). Hydrothermal activity and the sulphur-rich fluids generated can be a source of sulphide minerals for lead, zinc and copper. Rock types found at Brothers Volcano were analysed as dacite

livelihood of marine scientists to explore and learn about the Earth’s oceans and the mysteries they hold. One of the greatest scientific discoveries of the twentieth century is of deep-sea hydrothermal vents. It is these vents that continue the age-old questioning of where did life on earth originate? Discovering the Vents: In 1977, a team of scientists set out to a location northeast of the Galapagos Islands to photograph the floor of the mid-ocean ridge (. Never did they expect to make one of the greatest

simulations, (3×3×3) meter fire room was used, the fire was at the center of the floor of the fire room, and 27 m height atrium. The vents in the fire floor were both (2×1.5) meter with located at 1 m above the floor with 20 oC ambient temperature. Figure 2.8 listed the early stage situation of the fire in a floor near to an atrium. The fire floor has 2 vertical vents named WA and WB and there are open to both the atrium and outside. The atrium ceiling is open, and it is assumed that there is an ideal

barophile found on the Pacific Ocean floor able to withstand extremely high pressures. It can grow up to 2.4 metres and inhabits environments with a temperature range of 2 to 30 degrees Celsius. It is one of many organisms that reside near hydrothermal vents, specifically black smokers that produce high levels of hydrogen sulphide. R. pachyptila inhabits the aphotic zone up to several miles below the surface where sunlight is non-existent, so photosynthesis is not an option and most organisms
