Would like to share some interesting technical paper references along with abstracts:

Buried beneath the Antarctic ice sheet for a period likely to be in excess of one million years, subglacial Lake Vostok is arguably one of the most unique environments on Earth. The lake may contain organisms that have evolved independently of the outside world, adapting to a cold, dark environment, with a limited supply of nutrients. The lake is of particular interest in its perceived similarity to the environment of Jupiter's Moon, Europa. Europa's ice-covered surface may mask a liquid water ocean that could be home to living organisms, proving that life can exist on planets other than Earth. Lake Vostok provides a unique opportunity for the testing of a prototype interplanetary probe destined for Europa, which could ultimately reveal the presence of life outside Earth. However, technical difficulties, particularly relating to the dangers of contamination, have resulted in increasing delays, meaning it may be years before an attempt at penetration into the lake becomes a reality. Here, an alternative approach is proposed using current technology, which could reveal invaluable information about the lake and its environment, without requiring penetration. Limited modelling studies support the presence of clathrates within Lake Vostok, and remnant hydrate structures have been identified in core samples of lake ice accreted to the base of the overlying glacial ice sheet. Analysis and modelling of gases trapped within these clathrates could reveal important information regarding the environment of the lake and the potential for life.

Wavelet transform-based noise attenuation techniques are applied to airborne radar data from the Vostok area (Antarctica). Comparison between Fourier, polynomial, and wavelet-based denoising methods shows that the latter is more effective in wow effect removal and high frequency noise attenuation. The analysis is performed with a Daubechies mother wavelet at the second level of decomposition. The proposed methods allow an average 3 dB signal to noise ratio increment compared with the polynomial and Fourier ones. (Longer abstract available)

Interesting technical paper that concerns both the Lake Vostok issue, as well as historical global temperature fluctuations.

Hope you guys find this interesting.

(Hope my link works ).

It doesn't . I think you'll have to open a new browser window and cut and paste it into the address and go directly to it. This is either me doing something retarded or it is because geocities doesn't allow linking.

The mars probes are still on mars. They were equipped with sensors that would supposedly detect any organic carbon based lifeforms, IE bacteria.

There is some controversy over just what the findings were for these sensors. There apparently was a blip detected, but on second analysis, there was nothing.

The interpretation of this was that either there was no bacteria present, and it was a glitch, or that it was some form of bacteria, but essentially ate itself leaving no residue.

Keep in mind that whoever is releasing this information (NASA) is also the ones that have a vested interest in not necessarily being truthful with such findings...

As far as the mars/deep ocean/lake vostok biosphere, they are describing a type of life that does not otherwise exist on the surface of the planet, but does exist in the deep sea volcanic vents.

On the surface, all life centers around the basis of photosynthesis (plant life being the base of the food chain for us). In the deep ocean volcanic vents, where sunlight physically cannot penetrate, there have been found very active and advances biospheres centered around chemosynthetic bacteria that survive mainly off of the sulfur compounds that are released from these volcanic vents. This has led to the evolution of an entire new class of lifeforms that could never have evolved on the surface.

It has been speculated that because Europa is known to have liquid water oceans, and is volcanically active, the same type of lifeform may have evolved there. This speculation has been carried over to Lake Vostok for the same reasons.

The article states:

WTF? Protect his identity from what? It's not like I have some strong to desire to mob his landing site, or be a part of the throng waiting at the hospital doors. What the heck is with that? And once again, no mention of what he is "ailing" from.
