Adult chat lines fl - Carbon dating inaccuracies
Two distinct sediment layers have formed in the lake every summer and winter over tens of thousands of years.
And finally, we must assume that there hasn't been any contamination in the specimen which we are attempting to date.
Scientific research has called the first two assumptions into question.
Marine records, such as corals, have been used to push farther back in time, but these are less robust because levels of carbon-14 in the atmosphere and the ocean are not identical and tend shift with changes in ocean circulation.
Bronk Ramsey’s team aimed to fill this gap by using sediment from bed of Lake Suigetsu, west of Tokyo.
In order to improve the accuracy of carbon dating, we must look at why these assumptions are questionable and how we can compensate for the uncertainties raised by our doubts.
