Smaller less expensive AUVs for underwater archaeology are being developed.
In January, work will start on a new project to transform the search for sunken cities, ancient shipwrecks and other subsea curiosities. Led by Italian researchers, Archeosub will build a new generation of robotic submarines, or autonomous underwater vehicles (AUVs), for marine archaeologists. “You can find plenty of human settlements not far from the coast,” Allotta said. “In the Mediterranean there will be a lot more Atlit-Yams waiting to be explored and studied.”
The goal of Archeosub is to put sophisticated AUVs in the hands of cash-strapped researchers. That, in part, means turning the costly, heavy technology of the military and oil industries into far cheaper and lighter robots. They must be affordable for archaeological organisations and light enough to launch by hand from a small boat, or even the shore, rather than from a winch on a large research vessel...

Here are a few excerpts from an article about the new technologies being used in archaeology.
Traditionally, archaeologists have been limited by the number of artifacts they can transport from the field or from a museum to a lab where they can be analyzed. And mapping large areas around or underneath a field site was not feasible. But now, techniques adapted from chemistry, the oil industry and other fields have injected new blood into the study of the past...
Frahm and his colleagues have developed a portable version of X-ray fluorescence (XRF), a common technique for determining the chemical makeup of an artifact. Using a kind of "ray gun," scientists fire X-rays at a sample, boosting the energy of electrons inside the sample, where they emit new X-rays that correspond to specific elements, such as zinc or copper...
By measuring the wavelength and intensity of the emitted radiation, scientists can figure out what elements are present and their abundance in an artifact. Currently, Frahm and his colleagues are using portable XRF to find the source of stone tools made of obsidian, a volcanic glass formed from fast-cooling lava...

Here is a link to an article on cyber-archaeology. The link will take you to a site where you can choose other links and obtain free ebooks.

One of the links will take you to an article on RTI.
In “New Eyeballs on Ancient Texts,” Zuckerman explains why RTI images, created by merging a series of pictures taken with multiple light sources at different angles and distances around an object, are much more powerful than standard digital photographs. When viewed on a computer, RTI images of ancient texts can be virtually manipulated to reveal subtle details invisible to the naked eye, such as the thickness of a letter inked on a Dead Sea Scroll or the impressed signs of an ancient and worn cuneiform tablet.

The weather is beautiful but not the best for beach detecting. I don't expect any big changes in the next week.
Happy hunting,
