Besides the new “sink” on the seafloor apostles discovered
#Cosmoread: Limestone towers a bevy, ‘dubbed sunk Apostles, “have been found beneath the waves off the coast of Australia.
Even more surprising, fragile limestone beneath the surface of the water tower about 165 feet (50 meters) was uncovered. Scientists first discovered the limestone pillars, called sea stacks, have uncovered beneath the surface of the water can be marked. (Most of these sea stacks form on the beach, above the water line.)
“Sea stacks are always moving as we saw with the one that collapsed in 2005, so it is very surprising that at any water depth can be protected,” David Kennedy, Australia a geographer at the University of Melbourne, said in a statement
Kennedy shoreline tower, which in 2005 was talking to one of the great fall.
A process that has a twelve Apostles limestone towers, Victoria, Australia to get out of the beach a handful of limestone stacks similar to the famous tourist attraction carved through were formed. These impressive sea stacks only occur when conditions are just right so that the water and air of a steep, vertical column or columns can destroy a slab of rock are: granite rocks very quickly, enough to erode are hard to the soft clay cliffs can not support the weight of the overlying rock pile. Because it is soft but has a high compressive strength of limestone provides the right medium, researchers at Sydney International Coastal Symposium paper, which was published in the Journal of Coastal Research will be presented today (March 10) wrote .
Victoria Kennedy and colleagues around the reefs, the abalone and rock lobster are home to hunt by commercial fishermen to map the seafloor survey. Beam sonar mapping of the ocean floor, while Rhiannon Bezore, a doctoral candidate in geography at the University of Melbourne found a series of small sea stack some rocks next to the sink.
Stubbier five apostles were very low and the twelve apostles – the highest tower about 21 feet (6.4 meters), the highest of the twelve apostles of the pillar on the shoreline 221 feet (67.5 meters) was compared with. Like brothers living in the coastline, sinking pillars are made of limestone and volcanic rock out any notion of a lack of rules that they were formed through volcanic activity. Based on these factors, the researchers concluded that the sinking of the apostles carved through the same process that created the Twelve Apostles.
Sea level rise in the region, taking into account historical data, the team hypothesizes that formed these ancient tower about 60,000 years ago, when sea level of at least 200 feet (60 meters) was lower than today.
Mysterious underwater pillars of a discrepancy, the researchers said.
