    Default The South Atlantic Anomaly

    Quote Posted by Amzer Zo (here)
    *********************************************
    What generates the scenario put forth in the video is this:
    ***************************************************
    South Atlantic Anomaly
    From Wikipedia, the free encyclopedia

    The anomaly at an altitude of approximately 560 kilometers[1]
    The South Atlantic Anomaly (SAA) is an area where the Earth's inner Van Allen radiation belt comes closest to the Earth's surface dipping down to an altitude of 200km (124mi). This leads to an increased flux of energetic particles in this region and exposes orbiting satellites to higher than usual levels of radiation. The effect is caused by the non-concentricity of the Earth and its magnetic dipole, and the SAA is the near-Earth region where the Earth's magnetic field is weakest.
    Position and shape
    The Van Allen radiation belts are symmetric about the Earth's magnetic axis, which is tilted with respect to the Earth's rotational axis by an angle of ~11 degrees. The intersection between the magnetic and rotation axes of the Earth is located ~500 kilometres (300 mi) more to the North, above the centre of the Earth. Because of this tilt and translation, the inner Van Allen belt is closest to the Earth's surface over the south Atlantic ocean where it dips down to 200km (124mi) altitude, and farthest from the Earth's surface over the north Pacific ocean.[2]

    A cross-sectional view of the Van Allen radiation belts, noting the point where the South Atlantic Anomaly occurs
    The highest intensity portion of the SAA drifts to the west at a speed of about 0.3 degrees per year, and is noticeable in the references listed below. The drift rate of the SAA is very close to the rotation differential between the Earth's core and its surface, estimated to be between 0.3 and 0.5 degrees per year.
    Current literature suggests that a slow weakening of the geomagnetic field is one of several causes for the changes in the borders of the SAA since its discovery. As the geomagnetic field continues to weaken, the inner Van Allen belt gets closer to the Earth, with a commensurate enlargement of the SAA at given altitudes.[citation needed]
    Effects
    The South Atlantic Anomaly is of great significance to astronomical satellites and other spacecraft that orbit the Earth at several hundred kilometers altitude; these orbits take satellites through the anomaly periodically, exposing them to several minutes of strong radiation, caused by the trapped protons in the inner Van Allen belt. The International Space Station, orbiting with an inclination of 51.6°, requires extra shielding to deal with this problem. The Hubble Space Telescope does not take observations while passing through the SAA.[5] Astronauts are also affected by this region which is said to be the cause of peculiar 'shooting stars' (phosphenes) seen in the visual field of astronauts.[6] Passing through the South Atlantic Anomaly is thought[7] to be the reason for the early failures of the Globalstar network's satellites.
    The PAMELA experiment, while passing through the SAA, detected antiproton levels that were orders of magnitude higher than those expected from normal particle decay. This suggests the Van Allen belt confines antiparticles produced by the interaction of the Earth's upper atmosphere with cosmic rays.[8]
    NASA has reported that modern laptops have crashed when the space shuttle flights passed through the anomaly.[9]
    ********************************************
    Most too often, this South Atlantic Anomaly is taken as meaning the Earth magnetic poles inversion is afoot... something which would need more evidence.
    Saves me starting a new thread:-)
    The South Atlantic anomaly is the effect caused by the newly discovered PYRAMID(S) in South America. (bet you weren't expecting that)
    In the documentary by the BBC "The Core", the NASA spokesman stated with verification that the refurbished Hubble telescope consistently failed, bordering destruction whenever the telescope passed over South America. Something had to be done. So everytime it passed over that particular region NASA had to power down the telescope and restart it afterwards. The anomaly location was pretty well known apparently, so a solution was found. Guess what:-)
    The Bush family bought a ranch in South America bordering three Nations with exclusive ownership, blah blah. Supported by half a military brigade (probably more) on the ground of US finest secret keepers. Now we know why.
    The anomaly is the same GRAVITATIONAL forces found in the Bermuda triangle and the Alaskan triangle. The Bermuda triangle anomaly was partly solved by the secret removal of ancient components from the Cuban sub sea PYRAMIDS. The remainder of the Bermuda triangle problem will be resolved when the mid Atlantic PYRAMIDS are raped by the same elite using American/French/UK tax dollars and logistic support. (this is why the French aircraft was downed in the Atlantic to move the resources into position).
    The anomalies are caused by each of the PYRAMIDS still having ACTIVE "Arks of the COVENANT" which are extra terrestrial super conductors each residing in the "Kings Chambers" of each of the pyramids.
    The Ark of the Covenant from Khufu was stolen by Moses and the twelve tribes returning to pay homage to the dead Pharaoh who hadn't a successor and in the political confusion, along with the accompanying "priests" of the exodus tribe nicked the Ark and accompanying records. The Ark had earlier been removed from the pyramid by Khufu, during which there was a god almighty explosion which damaged the granite sarcophagus and granite roof.

    Maritime mystery: Is the growing South Atlantic Anomaly causing ships to sail in circles, unable to steer?

    Alexander Martin
    Sky News
    Thu, 04 Jun 2020 14:47 UTC



    Something bizarre happened to an oil tanker sailing near Cape Town on Sunday - ships were sailing in circles, unable to steer.

    In the early hours of Sunday 31 May, senior officers aboard the oil tanker Willowy were called to the bridge to be told that their ship and four others in its vicinity were mysteriously sailing in circles, unable to steer, and on course to converge.

    It must be easy to panic at sea. The immediate presumption was that strong currents were pushing the vessels around, but there were no such currents where the ships were sailing in the south Atlantic Ocean, west of the South African city of Cape Town.

    Ships appearing to sail in circles have become an increasingly common and mysterious phenomenon near a number of ports on the coast of China, especially near oil terminals and government facilities - but nothing had been seen where the Willowy was.

    Researchers monitoring these bizarre circles near the Chinese coast believe they are probably the result of systematic GPS manipulation designed to undermine a tracking system which all commercial ships are required to use under international law.

    Known as AIS (automated identification system), the technology broadcasts unique identifiers from each vessel - along with the vessel's GPS location, course and speed - to other ships nearby.

    These signals are even collected by satellites and used to monitor suspicious behaviour, including smuggling, illegal fishing, and - most relevantly - trade in sanctioned oil.

    The circles spotted near the Chinese coast have been attributed to GPS interference, something which coincided with US sanctions on Iran, according to Phil Diacon, the chief executive of marine intelligence firm Dryad Global.

    But according to a global analysis of this data by environmental groups SkyTruth and Global Fishing Watch, a number of circling incidents have also occurred quite a distance away from Chinese ports, with some impossibly appearing miles inland near San Francisco.

    SkyTruth found the real locations of these ships often thousands of miles away from the circular sailing tracks. The ships were again were often actually near oil terminals or in locations where GPS disruption had been reported before.

    But this was not the case for the Willowy.

    The real location of circling ships.

    At approximately 1am on Sunday morning, the Liberian-flagged crude oil tanker, operated by Singaporean business Executive Ship, suddenly swung starboard and began actually sailing in circles.

    The ship was unable to steer and the crew reported that four other vessels in its vicinity were caught in a similar spiral, slowly converging on each other for an unknown reason.

    "GPS interference can have serious consequences, with half of all casualties at sea linked to navigational mistakes," as Mr Diacon told Sky News, although such interference targeting other vessels rather than the AIS tracking system is highly uncommon.

    There are suggestions that GPS jamming has been used by the Iranian Revolutionary Guard Corps to dupe commercial vessels into entering Iranian waters, and Chinese electronic warfare capabilities have been proposed as a potential cause for some ships appearing thousands of miles away from where they really were.

    The crew aboard the Willowy were aware of these issues but none of these risks could be feasible west of Cape Town - a long way from the Strait of Hormuz or the contested South China Sea.

    But the European Space Agency has detected something else there.

    Nobody knows why, but the Earth's magnetic field - which has lost almost 10% of its strength over the last two centuries - is growing particularly weak in a large region stretching from Africa to South America, impacting satellites and spacecraft.

    Known as the South Atlantic Anomaly, the field strength in this area has rapidly shrunk over the past 50 years just as the area itself has grown and moved westward. And over the past five years a second centre of minimum intensity has developed southwest of Africa, very near to where the Willowy was sailing.


    The South Atlantic Anomaly is growing

    One speculation regarding this weakening is that it is a sign that the Earth is heading for a pole reversal - in which the north and south magnetic poles flip.

    This flip won't happen immediately but instead would occur over the course of a couple of centuries during which there would be multiple north and south magnetic poles all around the globe.

    The impact would be enormous for seafaring vessels whose navigation was based on magnetic compasses - causing them not only to sail in circles, but perhaps not even realise it.

    Fortunately, as the crew and the company's onshore marine superintendents knew, it has been decades since magnetic compasses governed maritime navigation.

    Modern ships like the Willowy use something called a gyrocompass instead, which finds true north as determined by gravity and the axis of the Earth's rotation rather than magnetic north.

    The gyrocompass is used alongside the ship's other systems to detect true north, identify the vessel's course, and steer it. If it was to fail it could cause exactly the issues which the Willowy was experiencing.

    The crew, alongside the company's shore-based marine superintendents, investigated and identified that the ship's primary gyrocompass was indeed malfunctioning.

    The ship resumed its course safely when it switched to using the secondary gyrocompass, along with an old-fashioned magnetic compass for good measure, Executive Ship confirmed to Sky News.

    Asked what caused the failure, the company described it as "an incidental breakdown" and added "repair will be done at the next port where the cause will be identified by shore technicians".

    But what about the other ships in the Willowy's vicinity, circling and seeming as if they would converge?

    A spokesperson for Executive Ship explained to Sky News: "The initial presumptive cause of circling for the Willowy was considered to be strong currents which also led the crew to perceive that other ships were circling too."

    With so many mysteries on the oceans, it must be easy to panic at sea.

    The above article, although interesting, fails to point toward the real actual mystery: what actually caused a gyrocompass to fail??? Not only that but what caused the other ships to circle as well?
