While I'm sure the actual connections between the Chrono Dead Sea and the Real world Dead Sea have been much discussed. However, being the closest Forum member to the actual Dead Sea, I feel I should share more knowledge, so you can add it to general knowledge. This is more trivia and comparison.
The idea that no life can live in the Dead Sea is false-As it turns out, some fungui and microscopic lifeforms inhabit the Dead Sea. Also, it is impossible to drown in the Dead Sea-like the Chrono Dead Sea, where you cannot sink into the water, though to it being frozen in time. The most well-known fact is that it's the lowest place on earth. The Dead Sea, being full of many different salts, produces certain substances which are a natural treasure-muds and such, which are very helpful to the skin, and are selled as cosmetics. The Dead Sea, as such, is known to contain a treasure, many benefical substances This is comparable to the Dead Sea in the Chronoverse, which contains a treasure of it's own, The Frozen Flame.
