You are correct in what you posted.
But it is annoying when creationists, such as Mindspawn, claim over and over that scientific dating methods are all wrong, sometimes with errors up to > 50,000 times, but then are unable to support those claims. But we've given them the chance to present their evidence, and the glaring lack of such evidence is very telling. (And no, the title is not a snide at anyone, that's just how you catch crabs and shrimp.)

Radiocarbon dates of marine shells are not reliable and have to be re-calibrated: http://www.folk.uib.no/...gerud%20and%20Gulliksen%201975.PDF All radiocarbon dates are calibrated. Calibration converts the conventional age into a calendar age. Marine shells have to be corrected for what is called the reservoir effect. This is because some of the carbon they absorb is older, "reservoir" carbon from deep water. That carbon is not in contact with the atmosphere. This correction, like the rest of radiocarbon dating, is well-understood and easily done. Scientists just collect modern (but pre-atomic bomb) marine shells and determine the "offset" in any given area. Your objection, then, that marine shells are "unreliable" is incorrect. With the reservoir correction they are quite reliable.
Diatoms naturally produce carbon. So we have to be careful to take that carbon producing effect into account when dating shells of creatures that produce carbon: http://www.sciencedaily.com/...ases/2008/01/080123150516.htm Diatoms, most of which are far too tiny to see without magnification, are incredibly important in the global carbon cycle, says Thomas Mock, a University of Washington postdoctoral researcher in oceanography and lead author of the paper. During photosynthesis, diatoms turn carbon dioxide into organic carbon and, in the process, generate oxygen. They are responsible for 40 percent of the organic carbon produced in the world's oceans each year. Your understanding of this paper in relation to radiocarbon dating is flawed. It simply does not say what you think it does, nor does what it says have anything to do with radiocarbon dating. The diatoms are simply converting the carbon from one form into another. They are not changing the ratio of the isotopes.
So the carbon ratio is most likely overexpressed in these shells, as is often observed in organisms that produce shells, combined with an overestimated timeframe, produces the "co-incidence". This is absolutely wrong. The ratio of the isotopes is not changed. It is incredibly difficult to discuss these matters with you when you simply google up an article, read a few lines, and jump to the conclusion that the article supports your argument when in reality it says something entirely different. You are demonstrating that you simply do not know enough about science in general, and radiocarbon dating in particular, to carry on a meaningful debate.

I admit I am partially ignorant on radiocarbon dating and do Google a lot, and am still learning. While learning I also probe a lot to test the validity of an argument. I feel that is what this forum is supposed to be about, promoting "understanding through discussion" but I do understand if you no longer wish to discuss this. With a bit of patience we can get through this. Here are some links, mostly written by religious scholars. I have not checked these to make sure the links are still current, but if you google you can find them if they are not. When you read these articles, try to do so with an open mind, not your current attitude that they have to be all wrong. You'll never learn anything otherwise.

Since you are unable to defend them, you will now please stop making those outlandish claims about dating.

Mindspawn has not been doing well on refuting current radiometric dating methods, and I doubt he will be participating much more in these threads.
I think that he has run out of "what ifs" to try to rationalize his beliefs, and is hesitant to participate any further because those beliefs might not be able to withstand the evidence we've been providing. At this point we're seeing one of several typical creationist retreats: in this case the problem is blamed on unfair moderation, rather than the poor quality of his arguments.Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.

Coyote, you are welcome to start a one on one public discussion if you would like. I feel bad that this thread was started by you in response to my request and yet I haven't given it the attention it deserved. Other than the moderation problem there are just too many posts in these public forums for me to keep up with. There is no moderation problem. There is only your habit of posting imaginary "what-ifs" as if they were evidence, coupled with chasing any convenient rabbit hole you can fall into. If you had any serious evidence you would have posted it by now. The issue of this thread is the accuracy of radiocarbon dating, but you have wandered into fantasies about sea water intrusion into one varve series while ignoring all the evidence that points to radiocarbon dating being sufficiently accurate to demolish both the young earth and global flood at 4,350 years ago claims. But, I'll play the game of a one-on-one thread if you like. However, I'm not going to chase you down rabbit holes. You'll stick to the topic or you'll be talking to yourself.Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.

Although scientists invent fictional scenarios, historical data from previous civilizations put the flood around 10-13,000 years ago. Archaeological data shows there was no global flood at that time.Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.

Different carbon dating, although not completely accurate due to the exposure of high radiation levels in the area at that time, suggest evidence of a general flood at multiple different times. Some studies suggest 2,000-3,000 BCE, others suggest 5,000 BCE. This is nonsense. Radiocarbon dates are calibrated against items of known age and any such factors are accounted for. See the various threads here for a lot of good information on the subject. Also, the folks to find any evidence of a global flood during the past several thousand years would be archaeologists and other scientists who deal with the soil -- and we have not found any such evidence. We do see evidence of an older flood though, occurring at the end of the last ice age. Google "channeled scablands" for the details. The point of this is that we can see the results of a small flood at the end of the ice age but can't see the results of a purported global flood more recently. That's because the global flood did not happen.Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge. Belief gets in the way of learning--Robert A.

You didn't address a single thing I wrote.
We have archaeological evidence that there was no global flood anywhere near 4,350 years ago. I have personally tested upwards of 100 sites containing that approximate time period and there has been no evidence of a flood in any of them. Rather, what I see is evidence of continuity in mtDNA, human cultures, fauna and flora, and sedimentation. This is evidence that there was not a flood at that time period. My colleagues have tested tens of thousands of sites with similar results. So, don't bother telling me about old myths when I have seen the real evidence first-hand.Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.

Have you excavated and tested the area of mesopotamia which is the area where the most common historical data of an ancient flood comes from? A global flood as described in the bible covered the entire world. Evidence should be found worldwide. It is not. Historical data is all well and good, but the absolute lack of physical evidence in archaeological sites kills off the flood myth completely.
P.S. Define "myth"

Coyote: Have you excavated and tested the area of mesopotamia which is the area where the most common historical data of an ancient flood comes from? I have not but my colleagues have. But it doesn't matter. If there is a claim for a global flood, as there is in the bible, then anywhere that claim is found to be incorrect is sufficient to disprove the claim! You seem to want to accept old tribal myths instead of real world evidence. That's not a very good bet. And again, you have failed to present any evidence for your position. But I can present evidence for mine: mtDNA evidence from On Your Knees Cave in southern Alaska (10,300 years ago) and Anzick in western Montana (12,600 years ago) produced a rare haplotype, D4h3. That haplotype is found among living individuals all along the west coasts of North and South America. If there was a global flood which wiped out everyone but Noah and his kin some 4,350 years ago you could not have the continuity of mtDNA that is shown in the above examples. In other words, no global flood. Get used to it--the global flood is a myth that is contradicted by real world evidence.Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.

Some of my forebearers were what you would call Bushmen. Those relatively small guys were digging for roots in the Kalahari. Getting sea food on beaches. And specialists in hunting antelopes. No flood legends involved. They have been here for at least 40 000 years. That's another example of the continuity of mtDNA that disproves the idea of a global flood during the past 40,000 years. Such a flood would have to produce a discontinuity of mtDNA, among other discontinuities.Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.
