44 Interesting Facts About the Ocean

Therefore, the Earth was years old. During the late 18th and early 19th century, a German mineralogist, Abraham Gottlob Werner, proposed that all of the Earth’s rocks were formed by rapid chemical precipitation from a “world ocean,” which he then summarily disposed of in catastrophic fashion. Though not directed toward the genesis of landforms in any coherent fashion, his catastrophic philosophy of changes of the Earth had two major consequences of geomorphic significance. First, it indirectly led to the formulation of an opposing, less extreme view by the Scottish scientist James Hutton in Second, it was in some measure correct: Asteroid impacts, Krakatoa-type volcanic explosions, hurricanes, floods, and tectonic erosion of mountain systems all occur, may be catastrophic, and can create and destroy landforms. Yet, not all change is catastrophic. This led to the theory of catastrophism , that the Earth was shaped by series of giant disasters and that they had to fit many processes into a short time scale. A French scholar, Bernard Palissy who lived from believed the Earth was much older based on his observations that rain, wind, and tides were the cause for much of the present-day appearance of the Earth.

This 340-Million-Year-Old Ocean Crust Could Date Back to Pangaea

Antarctica is said to posses pyramids as well. Our poles are shifting again. If the poles shift reaches 40 degrees, then the poles will flip and reverse, causing untold cataclyms that are likenedd to the End Times Prophecies of Revelation and the Hopi tribes.

The stripes ran parallel to the mid-ocean ridges and extended out hundreds of miles on either side of them. The seafloor’s permanent magnetic signatures showed that new ocean crust was created at the ridge crests and then spread outward in both directions.

Whales and some other large marine animals feed on and follow large aggregations of zooplankton for sustenance. Based on simple trophic structure, this would mean whales and other large zooplankton feeders can be found at higher abundance around areas of high primary production, potentially making them important exporters of carbon to depth through food falls. Biological pump models indicate that a large amount of carbon uptake by the deep sea is not supplied by particulate organic carbon POC alone, and must come from another source.

Lateral advection of carbon, especially in coastal areas contributes to this deficit in the model, but food falls are also another source of organic carbon for the deep ocean Higgs et al. Various percentages of the food fall contribution to the total carbon flux to the deep ocean have been hypothesized, ranging from 0.

There is growing evidence that the contribution of food falls to the deep ocean carbon flux is larger than originally proposed, especially on the local scale in areas of high primary productivity. Unfortunately, contributions of food falls to the biological pump are hard to measure and rely on a few serendipitous studies on discovered falls Smith et al.

Dirt from ocean floor could boost quake prediction

These are K-Ar data obtained on glauconite, a potassium-bearing clay mineral that forms in some marine sediment. Woodmorappe fails to mention, however, that these data were obtained as part of a controlled experiment to test, on samples of known age, the applicability of the K-Ar method to glauconite and to illite, another clay mineral. He also neglects to mention that most of the 89 K-Ar ages reported in their study agree very well with the expected ages.

Evernden and others 43 found that these clay minerals are extremely susceptible to argon loss when heated even slightly, such as occurs when sedimentary rocks are deeply buried.

Whatever your motivation we have created this list of interesting facts about the ocean to document some of the more captivating facts about the largest bodies of water on planet earth. Three-quarters of this planet is covered by water bodies, with the biggests ones being the five oceans the Atlantic, Pacific, Southern, Indian, and Arctic oceans.

Ninety four percent of all life forms on Earth are aquatic. Oceans have an average depth of two and a half miles ft. The ocean is three percent salt. Its salinity is estimated to be around 34 to 36 ppt parts per thousand , whereas fresh water has a salinity of 0 ppt.

The Age of the Earth

A sixgill shark caught on a line for research purposes. Dean Grubbs By Mark Kaufman They tightly wound the fish to a metal pole extending out from the undersea craft to tempt whatever might be lurking, three thousand feet below. Grubbs, a shark scientist at Florida State University, only hoped to attract a little-seen creature that largely dwells in the lightless ocean depths: A landmark climate change ruling could go up in smoke after Justice Kennedy retires “They’re one of the oldest lineages of living sharks.

That, by itself, makes them cool,” Grubbs, who with his long black hair and dark beard looks like he would fit right in at an Iron Maiden concert, said.

Scientists date sea-floor rocks by looking at patterns in the rocks, including magnetic patterns, and by looking at the geomagnetic reversal time scale.

Gillaspy has taught health science at University of Phoenix and Ashford University and has a degree from Palmer College of Chiropractic. Sea floor spreading is the process by which new oceanic crust is formed by the upwelling of magma through diverging tectonic plates. Learn about the relationship between sea floor spreading and polar reversals detected on the ocean floor.

Mid-Ocean Ridge Imagine you are a scientist living in the s. The first somewhat useful submarines were starting to appear, yet these early vessels were not well-suited for exploring the tremendous depths of the oceans. So, you would have been left with little more than speculation as to what the ocean floor looked like.

What is LIDAR?

Scientists used maps and other data gathered during the war to develop the seafloor spreading hypothesis. This hypothesis traces oceanic crust from its origin at a mid-ocean ridge to its destruction at a deep sea trench. Scientists realized that seafloor spreading could be the mechanism for continental drift that they had been looking for. List the main features of the seafloor: Describe what seafloor magnetism tells scientists about the seafloor.

Radiometric Dating: Clair Patterson Radioactive elements decay, releasing particles and energy. Nineteenth century geologists recognized that rocks formed slowly as mountains eroded and sediments settled on the ocean floor.

The boundaries of these plates are where the main tectonic actions take place. These tectonic actions include earthquakes, volcanoes, mountain building and sea floor spreading. Thus, an analysis of the rock types comprising the ocean floor should best begin where ocean floor itself begins… along the Mid-Ocean Ridges.

Ancient Myths About the Oceans The people who lived around the Mediterranean Sea began exploring this nearly landlocked sea several thousand years ago. Voyages of Exploration and Science: The Age of Discovery About years ago, European explorers turned to the sea to find faster trade routes to cities in Asia and Europe. Discovering the Gulf Stream Besides being a famous statesman and diplomat, Benjamin Franklin was a well-known American scientist. He contributed to oceanography in the mid- to late s by making and compiling good observations of ocean currents off the US East Coast.

Charles Darwin and the Voyage of the Beagle In , and in the teeth of a gale, the HMS Beagle, a British warship, left Devonport, England, for an expedition to map the South American coastline and to carry out chronometer surveys all over the globe.

Types of Rocks Found on the Sea Floor

Reference to a case where the given method did not work This is perhaps the most common objection of all. Creationists point to instances where a given method produced a result that is clearly wrong, and then argue that therefore all such dates may be ignored. Such an argument fails on two counts: First, an instance where a method fails to work does not imply that it does not ever work. The question is not whether there are “undatable” objects, but rather whether or not all objects cannot be dated by a given method.

The Dutch government had tasked them to assess the condition of two particular Dutch vessels, the Hr. De Ruyter, both sunk in during the Battle of the Java Sea, not far from the remote island of Bawean. Conditions there are notoriously dangerous: Seemingly endless schools of stinging jellyfish and currents capable of sweeping away even a master diver.

But as they descended deeper and deeper, the ships remained elusive. Are we using the right coordinates?

Right off the beach is a quaint downtown offering shopping and dining. Five fishing groups had sued to stop the research, led by Rutgers University and involving the National Science Foundation and the University of Texas, claiming it disturbs and might harm marine life including dolphins, whales, turtles and many fish species.

But in a joint court filing Wednesday, both sides acknowledged that the testing had been completed on Monday, and that a restraining order shutting it down is no longer needed.

What better way to monitor the approximately 95, miles of U. Since the early s, the National Geodetic Survey has been doing that—taking photographs from airplanes to capture the Earth below. Today, the capture of these aerial photographs is controlled by Global Positioning System techniques and the photos are used to define the national shoreline, create maps and charts, monitor environmental change, and provide damage assessment in response to manmade or natural disasters.

The primary aerial photographic product is a high-resolution 39 megapixel digital color photograph. Depending on the camera lens, photos can be taken in black-and-white or near-infrared. Traditionally, photos are captured while flying at 10, feet over the ground. Each photo covers an area of approximately two square miles of the Earth’s surface.

Each photo is spatially referenced by the Global Positioning System so that accurate latitude and longitude information can be determined for any location in the photo. LIDAR images are similar to digital photographs in that they are high resolution images that provide positional information. However, unlike digital photographs, LIDAR images also provide an extremely accurate means for measuring the height of objects on the ground. Digital imagery has been primarily used since

Why are countries laying claim to the deep-sea floor?

LIDAR data supports activities such as inundation and storm surge modeling, hydrodynamic modeling, shoreline mapping, emergency response, hydrographic surveying , and coastal vulnerability analysis. LIDAR, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure ranges variable distances to the Earth.

These light pulses—combined with other data recorded by the airborne system— generate precise, three-dimensional information about the shape of the Earth and its surface characteristics. Airplanes and helicopters are the most commonly used platforms for acquiring LIDAR data over broad areas.

The Radiometric Dating Game Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years. We are told that these methods are accurate to a few percent, and that there are many different methods. We are told that of all the radiometric dates that are measured, only a few percent are anomalous.

This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points. Since there doesn’t seem to be any systematic error that could cause so many methods to agree with each other so often, it seems that there is no other rational conclusion than to accept these dates as accurate.
