In the interview, Rogers explained why the 1988 carbon-14 dating
had been invalid because samples contained significant amounts of new material from discrete repairs to the cloth.
However, in 1988, carbon-14 dating
of a sample cut from a corner of the shroud indicated that the material originated between 1260 and 1390.
of 100 of the specimens show that the cave has been almost continuously occupied during the past 40,000 years, which indicates ice didn't cover the cave's entrance for any extended period.
Its unique instruments and exploration vehicles range from a high-precision carbon-14 dating
lab to the deep-diving submersible ALVIN and remotely operated and autonomous underwater vehicles.
Miller's team also used carbon-14 dating
and a similar technique that relies on the radioactive decay of uranium atoms.
Oceanographers had previously relied on the carbon-14 dating
technique to judge the age of deep-sea sediments, but this method reaches back only 45,000 years.
From carbon-14 dating
of the sediment core layers, Bond pinpointed the ages of the peak coolings to 1,050, 3,050, 3,950, 5,650, and 8,050 years ago, with each cold spell lasting about 800 years.
Using the carbon-14 dating
technique, Stute and his colleagues determined an age for each water sample.
The scientists, from the University of Pisa and the University of Milan, used carbon-14 dating
to determine the age of ancient Adelie bones, feathers, eggs, and guano.
In the April 30 SCIENCE, Stanley and Warne reported that carbon-14 dating
technique suggested that various parts of the delta were sinking 1 to 5 centimeters per decade.
of organic material on the terrace indicates that the uplift occurred between 500 and 1,700 years ago.
