the notation "...Heavy water table ..." could possibly be a reference to the use of deuterium oxide, a chemical compound similar to regular water. It has several uses, among which are 1) nuclear magnetic resonance spectroscopy [which provides detailed information about th three dimensional structor of biological molecules,has also been used to build elementary quantum computers], and is used for nuclear shielding; 2) neutro moderation, a procedure used in the production of weapons-grade uranium; 3) metobolic rate testing in humans and animals ... all three of which certainly fit in with the whacky events that have taken place or have been suspected or seen by the "losties". While Heavy water does not exist in nature and must be humanly produced, the use of the word "table" in the notation might mean that a natural source of Heavy water was found in that area.

Sorry for the double posting.

I think D.I.H.G. survey team means Dharma Initiative/Hanso Grant survey team, referring to the money Alvar Hanso put up for the project.
Also, the medical station is named Caduceus Medical Station. The word caduceus is well known to medical personel. It is a symbol of a short rod entwined by two snakes and topped by a pair of wings, which is actually the caduceus or magic wand of the Greek god Hermes (Roman Mercury), messenger of the gods, inventor of (magical) incantations, conductor of the dead and protector of merchants and thieves. There are occult associations with the caduceus.

The annotation following "ALLEGED LOCATION OF ABORTED #7" is not 'Each number of heavy water table". It is "Large number of underground springs / heavy water table". So, nothing to do with heavy water / deuterium; just that the ground is too wet for successful excavation,

"Magnus Hanso" indeed means "the great Hanso," whatever THAT means. In Latin, directly under "The Pearl" is the ancient sailor's warning "here be dragons."

Now as a biologist, I translate the following abbreviations with a bit of a bias: D.I.H.G. is "Dharma Institute of Human Genetics"; A.H. refers to accelerated healing processes; R.V.s are retroviruses; M.D.G. is molecular developmental genetics; and the C.V.s are cryogenic vaults. The large chamber with "seemingly heavy water table" suggests a deuterium problem... highly odd, but the result of a leaking reactor container.

See where I'm going with this?

maybe the large '?' in the middle is a large electro magnet which powers all the other stations.

also how big is the Island and is it definatly an Island maybe its connected to a mainland and the plane didnt really crash in the pacific but somewhere more civilised like south amereica

heavy water is "Heavy water is deuterium oxide, or D2O or 2H2O. Its physical and chemical properties are similar to those of light water, H2O, but the hydrogen atoms are of the heavy isotope deuterium, in which the nucleus contains a neutron in addition to the proton found in the nucleus of the hydrogen atom. This isotopic substitution alters the bond energy of the hydrogen-oxygen bond in water, altering the physical and chemical properties of the substance. Gilbert Newton Lewis isolated the first sample of pure heavy water in 1933." (Thanks wikipedia)

so radiation is involved here somehow

Magnus is latin for great, big. Great episode

It's all claer now.

Lost was/is the original TV reality show with subjects (unbeknwn to themselves) thrust upon the island in several tranches. Their tribal beahavior is then monitored over a couple of decades with the plane crash being the last tranche.

Hidden in the trees are the camera crews;) It's all gone madly wrong as the newtwork canceeled the show years ago and abandoned the players and the crews. All typical of the heartless actions of networks when they cancell shows.....;)

I swear, when Lost ends, theres gonna be suicides....
