Cuban 'Atlantis' Cover-Up Solved?

If you wash large amounts of ocean water onto the continental shelf, what does the additional weight do to the landmass?

HEY HWD. - Not to be a drag, but can we stay away from Atlantis? I am only asking as it has been debated and stated througout the thread that the word was used metapohorically and is not the point of the discussion. I'm also afraid of it as it is a thread derailer that no one will ever agree on anyway. Thanks!

There weren't any Cuban inhabitants sailing to Australia in ancient times that I know of.

I am saying that it is anomoulous, given the Ice Age map, that these coastal peoples did not go to Cuba given its proximity. I do not think it is possible there was not settlements there during the Ice Age, and the reason for the current artifacts dating to 8k is because any other evidence would be below water.

A comet/asteroid impact on a large glacier mass could cause the following effects:
Release vast quantities of heat.
Produce massive earthquakes.
Produce trapped superheated steam that would exert force to uplift and move a large glacier mass.
Fracture glacial sheets.
Eject water, steam and ice high into the atmosphere.
Release stored potential energy.
Produce a partial glacial ice melt.
Produce an almost immediate rise in sea level.
Produce great rainfall.
Slowly driving the ocean crust deeper.
Slowly raising the continental crust higher.
Produce volcanoes and lava flows.
The impact of a large comet/asteroid (~2 mile diameter) with an Ice Age glacial sheet could produce the following chain of events:

The impactor penetrates through miles of thick ice, like a bullet. Below the surface, the impact releases the energy of a million nuclear bombs. A gas bubble of trapped superheated steam forms. The steam causes a general uplifting of the glacier ice sheet. The ice sheet rises like a steam boiler about to burst. The gas bubble exerts tremendous force on the ice flow. The impact triggers the release of potential energy locked in ice flow allowing million of tons to break loose and begins to move on the frictionless fluid bed toward the oceans. Some of the steam escapes like an erupting geyser or volcano. The glacier sheet fractures, opening up fissions for the steam to escape. Boiling water and steam further lubricate the surface boundary layer of the ice flow. The explosion hurls large masses of ice fragments into the air with great force. Ice and water flowing off the continents cause an immediate rise in sea level in conformance with the Displacement Theory. TThe released superheated steam falls back to Earth, generating very violent storms. Heavy rain falls for several days and weeks. The atmosphere heats up.

Large earthquakes combined with the Earth’s crustal rebound from the movement of large ice sheets exert significant strain on the tectonic plates. The strain is relieved by the eruption of volcanoes, and lava flows throughout the world. Underwater earthquakes expose frozen methane hydrate beds. The heat generated at the impact point and the heat from underwater volcanoes and lava flows elevate the temperature of the ocean bottoms and melt the exposed methane hydrate. The released methane bubbles to the surface, where in time it is ignited by lightning strikes, which further raises atmospheric temperatures. The methane burn releases large quantities of carbon dioxide into the atmosphere. In the end, the global temperature rises significantly, breaking the back of the Ice Age.

Final Thoughts: Remnants of the Ice Age civilizations exist but they are buried under many feet of silt and sand, four hundred feet below sea level, far too deep for most divers. I predict that some of the greatest archeological discoveries in the 21st century will be uncovered off the coastlines, buried hundreds of feet underwater.

Since we know that something like a cometary impact likely happened towards the end of the last ice age (but we don't know the scale/size),

New scientific findings suggest that a large comet may have exploded over North America 12,900 years ago, explaining riddles that scientists have wrestled with for decades, including an abrupt cooling of much of the planet and the extinction of large mammals....

According to the scientists, the comet before fragmentation must have been about four kilometers across, and either exploded in the atmosphere or had fragments hit the Laurentide ice sheet in northeastern North America.

Ice and water flowing off the continents cause an immediate rise in sea level in conformance with the Displacement Theory.

alculating from a date of c. 12,900 years ago, which indicates sea level was 60 meters/75 feet lower than today the previous map would look slightly different. However, the indication here would be 60 meter rise in roughly 4000 years. That would come out to an average of .015 meters/.59055 inches per year. Definitely slow enough for people to have excaped from.

This is not to say a comet or asteroid didn't impact or the glaciers didn't melt, just that there is no evidence of it causing a quick rise in sea level.

The rate of sea level rise slowed between 14,000 and 12,000 years ago during the Younger Dryas cold period and was succeeded by another surge, "meltwater pulse 1B", 11,500-11,000 years ago, when sea level may have jumped by 28 m according to Fairbanks,

"This event happened near the end of the last Ice Age, a period of de-glaciation that lasted from about 21,000 years ago to 12,000 years ago," Clark said. "The average sea level rise during that period was about eight millimeters per year. But during this meltwater pulse there was an extremely rapid disintegration of an ice sheet and sea levels rose much faster than average."

The amount of sea level rise that occurred during a single year of that period, Clark said, is more than the total sea level rise that has occurred in the past 100 years.

The cause of this event, called the "global meltwater pulse 1A" since it was first identified in 1989, has until now been unknown. This study not only pinpoints the source of the meltwater pulse, but it also makes clear that significant climatic events can occur very rapidly and unpredictably.

This type of melting event thousands of years ago is different from the more recent events in Antarctica, researchers say, such as the breakup of a large percentage of the Larsen ice shelf earlier this month. But the dramatic melting illustrates the pressing need for a better understanding of Antarctica's huge ice sheets and their stability.

"We can't say at this point whether the recent breakup of part of an ice shelf in Antarctica has any relevance to this type of huge meltwater event that originated from Antarctica thousands of years ago," said Peter Clark, a professor of geosciences at OSU and one of the world's leading experts on glaciers. "We don't know yet how important these ice shelves are to stabilizing the larger ice sheets of the continent."

What is very clear, however, is the importance of Antarctica's huge ice sheets remaining stable. The West Antarctic ice sheet is thought to be potentially unstable, and if it collapsed sea levels around the world would rise almost 20 feet. The melting of the larger and more stable East Antarctic ice sheet would raise Earth's sea levels another 200 feet.

And during this comparatively short period thousands of years ago, it is now known that these two huge ice sheets were anything but stable. One or the other, or some combination of the two, melted at a surprisingly rapid rate and caused a 70-foot surge in sea levels in just a few hundred years.

"This event happened near the end of the last Ice Age, a period of de-glaciation that lasted from about 21,000 years ago to 12,000 years ago," Clark said. "The average sea level rise during that period was about eight millimeters per year. But during this meltwater pulse there was an extremely rapid disintegration of an ice sheet and sea levels rose much faster than average."
