		<description><![CDATA[This project has advanced a geophysical approach for identifying buried archaeological sites that combines recently developed down-hole magnetic capabilities with laboratory soil magnetic techniques.  Down-hole magnetic susceptibility measurements allow the effective location of paleosols while soil magnetic studies are used to evaluate whether an associated human occupation is likely.  This combined geophysical approach has the potential to locate and explore buried archaeological deposits across varied environments in a cost-effective, efficient, and relatively non-invasive manner.]]></description>

The shell middens, forts, and shipwrecks of the Gulf area are treasures that represent a wide swath of history—a veritable gumbo of cultural treasures. Dr. Meredith Hardy, an archeologist with the National Park Service&#8217;s Southeast Archeological Center (SEAC), explains the importance of these cultural resources and how they are being protected.

One can suppose ancient people living by natural light were more compellingly struck by the sight of comets and supernovae, and understandably researchers seek images of them in the shapes of rock-art motifs. An absolute dating contradicts that supposition in respect of a presumed image of the visible supernova of AD 1054.]]></description>

		<description><![CDATA[We developed a plasma-chemical technique to remove carbon from rock paintings. This extraction is followed by
accelerator mass spectrometric analysis of the 14C to yield direct estimates of the ages of rock paintings. We have demonstrated
use of the technique on charcoal as well as iron and manganese pigmented paintings. Unfortunately, there are no rock paintings made with inorganic pigments that have accurately known ages. That means there are no primary standards for checking the accuracy and validity of our technique on this type of samples. To compensate for this, known age samples (charcoal and Third International Radiocarbon Intercomparison wood) were dated: these support the general validity of this technique.]]></description>

		<description><![CDATA[Much of the information needed for effective archeological preservation is hard to see.  For objects, sometimes that information is encased by layers of corrosion.  For whole sites, sometimes it is buried beneath centuries of sediment.  And sometimes that information is inaccessible simply because it has not been shared with others.  In 2009, NCPTT focused on looking “beneath the surface.”  It focused on using technology to see what was hidden, to see what preservation clues could be revealed, and, critically, how those discovery methods could be taught to other professionals.]]></description>

		<description><![CDATA[In this episode, Jason Church speaks with Curtis Deselles, an intern with the Materials Research program at NCPTT, discusses the use of eddy currents and eddy current technology in conservation science. Mr. Deselles has built several eddy current analyzers, custom software, and presented on this topic at a non-destructive conference in St. Louis.<br /><br />
NCPTT has been using eddy current technology in preservation and will be bringing this tool to the iPhone platform in 2010. <a href="http://ncptt.nps.gov/Podcasts/archive/Preservation-Technology-Episode-8-Eddy-Currents.mp3">Download Episode 8 as an mp3</a> or <a href="http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewPodcast?id=285727030">subscribe via iTunes</a>.]]></description>

		<description><![CDATA[A variety of materials and methods have been used to preserve ceramic vessels.  Many have proven successful, while others are damaging.  Monitoring and evaluation of past treatments is a documented research priority in the conservation field.  The Arizona State Museum (ASM) has examined, recorded and analyzed the performance of past treatments on 20,000 southwest vessels and a modern storage facility.<br /><br />This research has afforded the opportunity to look forwards and backwards to identify patterns in archaeological methods, museum management and conservation.]]></description>

		<description><![CDATA[One of the biggest barriers to the rapid spread of cutting edge, innovative technologies in archeology is cost.  Let’s face it: things that end in “-ometer” or “-oscopy” tend to be pricey.  And if they are really new, or if their utility in some contexts has yet to be proven, the price remains in the stratosphere [...]]]></description>
