During the several ice ages that have occurred in recent history, sea levels dropped significantly and added 40% of land to the continents say researchers looking at these now re-submerged areas. When these great expanses of land were exposed they were home to plants and animals, including ancient people. researchers are discovery ancient artifacts under the sea that point to prehistoric cultures and settlements that would have been on the coast. Some of these sites are tens of thousands of years old and tell a lot about ancient peoples and their lives near the ocean. Tis research has been named "Continental Shelf Prehistoric Research,"and combines the fields of oceanography archeology and geoscience. Researchers not only look at the artifacts of these ancient civilizations, but also at ocean patterns and rising and falling ocean levels that would have affected these people. These scientists working in this new field want support from European governments to help them progress in their research and study these sites before they are destroyed by erosion an other factors. Researchers have found, hatchets, canoe paddles, hut foundations, simple flint blades, and many other items in these ancient sites.
