Hydrothermal vent Essays

Chapter 1: Hydrothermal vent habitats As light penetration at depths below 300 meters is inadequate to support photosynthesis, ambient seawater temperatures below 1000 meters lie between 1 and 5⁰C and hydrostatic pressure increases with 1 atm for every 10 meters of water depth, for a long time the deep sea was not regarded to be a very habitable environment (van Dover, 2000). However, since the discovery of hydrothermal vents in 1977 this view has drastically changed (Corliss et al., 1979; German

The existence of life in the extremely harsh conditions of hydrothermal vents has stimulated an increasing research effort on the diversity, ecology, and physiology of vent organisms, as well as new avenues of research into the origins of life on Earth and even into the occurrence of life elsewhere within and outside the solar system (Russell et al, 2008). Several decades of exploration have resulted in the detection of numerous vent sites and faunal assemblages at many mid-ocean ridges and back-arc

Hydrothermal vents are categorized by the temperature of the hydrothermal fluids released. One type of hydrothermal vents are called white smokers. White smokers release hydrothermal fluids of temperatures around 30-350°C (86-662°F) (Karimi, 31). These vents release lighter hued minerals such as barium, calcium, and silicon. They also tend to be lower in temperature due to how far away they are from the source of heat (“Boletín de la Sociedad Geológica Mexicana”). Another type of hydrothermal vents

MYSTERY: RINGING ROCKS [USA] A. Introduction of Essay (with Thesis Statement) [5 Marks] Ringing rocks is known as one of the mystery places in the world. When the rocks are struck with a hammer or another rock, they sound as if they are metal and hollow, and ring with a sound similar to a metal pipe being struck. The rocks themselves are composed of diabase, the same type of rock that makes up most the earth's crust. The viewpoints of three researchers are being presented briefly in this assignment

Mining the hydrothermal vents could make it so that some very bad things could happen to our earth. Mining is very bad idea until we finish all of the studies about hydrothermal vents because very bad things could happen to fish and the communities nearby the mining. First, The vents are used as homes for species. Mining could wipe out all of the yet to be discovered species. Mining will pollute the water and let out toxins that can kill species and communities near by. Mining the hydrothermal vents

How Does The Marshall Hydrothermal Recovery System Work? Nowadays, it seems as if everyone is plugged in and in constant need for energy. Dependant on energy, our generation gets most of it from fossil fuels, nuclear technology, and solar power, however, could there be a way of harvesting energy at a much more efficient rate than we currently are? The Marshall Hydrothermal Recovery System is a way we can reap the mass amounts of heat produced by naturally occurring sea vents deep down in the ocean

presents a better understanding of the chemical compositions that existed during the evolutionary transitioning, from geochemical processes to biochemical processes (Baker & German, 2004). However, there is a reason to doubt the origin of life from hydrothermal vents. One of the main arguments against the origin of life from the deep sea, is the fact that so many macromolecules are found in biology. Molecules such as DNA, RNA, proteins and lipids are all polymers and form via condensation reactions – a wet

been discovered. Some like the zombie worms have baffled scientists. Others like the deep sea jellyfish have just shocked scientists. Then, there are some like the yeti crabs, which have just confused scientists with how they survive in the hydrothermal vents near Antarctica. Though some people see these just as deep sea animals, they are very interesting and provide so much information. Zombie worms live on the bottom of the California coast and they thrive on whale bones. These are bones “which

Extremophiles and Humanity The Guinness Book of World records puts the tallest man ever at 2.72 meters tall, clocks the fastest mile at 3 minutes and 43.13 seconds, and weighs in the heaviest baby born at 9.98 kg (n.d.). There are ridiculous records such as fastest 100 m hurdle in swim flippers, most toilet seats broken by a head in one minute, and countless other records that make you wonder how and why people thought of them. Adrenaline junkies chase the high they get from putting their life in

Yellowstone National Park is home to nearly 10,000 hydrothermal features (Nat'l Park Service U.S Dept. of the Interior). The hydrothermal features are caused by hydrothermal systems. These systems are dependent upon the molten rock beneath Yellowstone’s surface. Yellowstone’s thermal features are not only dependent upon molten rock but also microorganisms called thermophiles. Thermophiles depend upon the extreme heat from the magma below the surface (Nat'l Park Service U.S Dept. of the Interior)

An alien is an intelligent being from a planet other than Earth. It is heavily debated whether aliens even exist or not. However, aliens most certainly do exist due to the fact that many planets have the ingredients needed for life, many planets are in their star’s habitable zone, and the universe is so large and old that there must be something out there. First, many planets have the necessary ingredients for life. The ingredients for life are liquid water, energy, and organic material. Mars,

Introduction Tardigrada, aka the Tardigrade is potentially the toughest animal on earth. They can be found almost anywhere - the top of the himalayas, japanese hot springs, deep ocean trenches, from polar regions to the equator. They make their homes in dunes, beaches, soil, lichens, mosses and marine and freshwater sediments. These tiny 1mm long extremophiles have been found to withstand the pressures of the deepest ocean trenches, mass amounts of radiation, and being heated to 150 degrees fahrenheit

Question #1a: Provide a thorough description of the contents of ocean water.            The contents of ocean water is that it is very salty. The salt in the ocean water comes from many different types of rocks on land. How the salt from rocks is that when rain falls down on land the rain will slowly erode the rock. How that is happening is the acid in the rain erodes the rock but it is not dangerous acid to us humans. When the rock gets eroded then it turns into ions which is an atom or molecule

There is no way that can expect the unexpected when it comes to energy resource in the United States. The market is ever so changing and who know what scientists will come up with next. In the US we use a couple of different resource for energy some are better than others but we are working on ways to figure which is best for the environment. The first one I would like to talk about it Bio energy also known as biomass. Biomass consists of organic material derived from living or recently living organism

Well, short answer is that it doesn’t confirm anything. The water is so saturated with salt that anything that could survive would have to be an extremophile. This isn’t hard to imagine considering on earth we are aware of bacteria living in hydrothermal vents and radioactive waste disposal sites. It certainly is an exciting discovery, but like most great scientific breakthroughs,

aided by enzymes or catalysts, to build RNAs sequences that lead to the beginning of life through time. The second theory was proposed was the Iron-Sulfur World Hypothesis. This idea described how mineral catalyst presented near the deep sea hydrothermal vents created a series of chemical reactions that potentially

Adaptations allow deep-sea creatures to survive in extreme environments. There are many different adaptations that allow an animal to survive. The three common adaptations consist of habitat, appearance, and diet. The Giant Squid, Zombie Worm, and the Yeti Crab utilized these adaptations to survive, and without them it would be difficult to nearly impossible to keep their species alive and flourishing. Each one of theses species is suited for its environment and survival tasks through its adaptations

Seventy percent of the Earth’s surface is occupied by oceans. However only five percent have been explored by oceanographers. Oceanography is a type of science that deals with the ocean. There are four different fields of Oceanography. They include Biological Oceanography, Chemical Oceanography, Marine Geology, and Physical Oceanography. Like any type of science, new technology is constantly being developed. Examples of these discoveries include the “Ground Penetrating Radar,”, and new submarines

could be essential to his research besides the abandoned shipwrecks. “On one of his most famous expeditions, Dr. Ballard and a team of scientists traveled to the Galapagos Islands in 1977 and discovered hot springs on the ocean floor called hydrothermal vents” (Education through Exploration). The

Exploring the Yellowstone Volcano – Atalanda Cameron Intro Hi, my name is Atalanda, and I am a Ranger here in Yellowstone. Today I’d like to talk to you about the Yellowstone super volcano, and the geological processes that shaped this area. The program will last about 20 minutes, and I am happy to stay longer to answer any questions after. If there are any junior rangers, I will sign your books and I encourage anyone else who would like to participate in our junior ranger program to pick up a book
