They have to use acids and, within that process, you lose a large part of your sample and you destroy it,” Blinman explained.

“But we now have the ability to date incredibly small amounts of carbon – 40-100 millionths of a gram – and that is the real revolutionary aspect of this.

And the ancillary part of that is it’s non-destructive.”That’s important to Nancy Akins, a research associate with the Office of Archaeological Studies, who in February was having a bison tooth and sheep bone tested by “Marvin’s Machine.” The items were excavated from the site of a rock shelter in Coyote Canyon north of Mora.“It could be 500 years old or it could be 5,000 years old,” she said of the bison tooth, the result allowing her to complete her report of the site that she’s determined to have been used by humans as a hunting outpost starting 1,700 years ago.“I’m just waiting on the dates, because it’ll change everything if we get dates where I can actually say, ‘OK, that’s what the sheep bones date to and that’s what the bison dates to.’ It tells us an awful lot about how they were using the land on the east side of the Sangre de Cristos.”Because a lot of that part of New Mexico is private property or under land grants, such finds as the one in Coyote Canyon are rare, she said.“Unless there’s a road or something, we don’t have any information at all.

This is one of the very, very few sites in Mora County that have been excavated,” she said of the site reported by the state Department of Transportation.

“But a lot of people just refer to this as ‘Marvin’s Machine.'”The process is important because, unlike other methods of radiocarbon dating that destroy the sample being tested, LEPRS preserves it.

It also works on tiny samples – even a flake of ink or paint – and is considered a more accurate means of dating.“With standard radiocarbon dating, there’s a risk of contamination of carbonates.

In addition, industry sponsored course projects, internships, and coop opportunities allow our students to gain real-world experience before graduation.

Founded in 2002 by Nobel Laureate Carl Wieman, the Ph ET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations.

(Eddie Moore/Albuquerque Journal)Marvin Rowe, a scientist at the New Mexico Office of Archaeological Studies, adjusts the Low Energy Plasma Radiocarbon Sampling device he built to date artifacts with minimal damage. That machine he built, and what it’s used for, helped Rowe win the prestigious Fryxell Award for Interdisciplinary Research from the Society of American Archeology two years ago.“We call the process Low Energy Plasma Radiocarbon Sampling,” said New Mexico’s state archeologist Eric Blinman, who credits Rowe with inventing the process.
