“20000 Leagues Under the Sea” Part2 Ch09

Question 1: Has man ever attempted colonizing the ocean depths?

Question 2: Are there underwater volcanoes?

Question 3: What ancient writers referred to the legend of Atlantis?  Is there archeological evidence of any cities having sunk under water in a relatively short amount of time?

Question 4: What ancient cities are now underwater?

Answer 4: According to Volume 11 “Provinces of the Sea” in the series “The Ocean World of Jacques Cousteau” by Jacques Cousteau, copyright 1975, published by the Danbury Press:

pg. 66: …We are currently in a period of rising sea level, which began about 20,000 years ago, an eyeblink in geological time.  But in some areas beaches rise and fall independently of sea level…One classicist has calculated that of the 300 important port and coastal cities built between 3000 B.C. and 476 A.D., half of them are now underwater.
