The Geographic South Pole is marked by the stake on the right NASA image showing Antarctica and the South Pole in 2005. The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is the point in the Southern Hemisphere where the Earth's axis of rotation meets its surface.
At mid-ocean ridges, new crust is created by the injection, extrusion, and solidification of magma. After the magma has cooled through the Curie point , ferromagnetism becomes possible and the magnetization direction of magnetic minerals in the newly formed crust orients parallel to the current background geomagnetic field vector .
They evidently cover like bushes extensive tracts of the bottom." [ 3 ] The identification was largely unknown outside marine biology circles until 2003, when a discussion of the Eltanin Antenna on a UFO mailing list caused researcher Tom DeMary to contact A. F. Amos, an oceanographer who had been aboard the USNS Eltanin in the 1960s.
Scientists believe they’ve discovered an ancient ocean floor comprising a new layer between Earth’s mantle and core.
The Ross Sea was discovered by the Ross expedition in 1841. In the west of the Ross Sea is Ross Island with the Mt. Erebus volcano; in the east is Roosevelt Island. The southern part is covered by the Ross Ice Shelf. [5] Roald Amundsen started his South Pole expedition in 1911 from the Bay of Whales, which was located at the
The ocean may be 10 kilometers (6.2 mi) deep at the south pole. [ 26 ] [ 98 ] Measurements of Enceladus's "wobble" as it orbits Saturn—called libration —suggests that the entire icy crust is detached from the rocky core and therefore that a global ocean is present beneath the surface. [ 99 ]
Visualization of the ice and snow covering Earth's northern and southern polar regions Northern Hemisphere permafrost (permanently frozen ground) in purple. The polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles.
Since experts started measuring the Anomaly a few decades ago, it has grown in size and now covers a fifth (20.3%) of Earth’s surface, with no signs of shrinking anytime soon.
