Scientists issue call to action for archaeological sites threatened by rising seas

28.10.2010
Should global warming cause sea levels to rise as predicted in coming decades, thousands of archaeological sites in coastal areas around the world will be lost to erosion.

With no hope of saving all of these sites, archaeologists Torben Rick from the Smithsonian Institution, Leslie Reeder of Southern Methodist University, and Jon Erlandson of the University of Oregon have issued a call to action for scientists to assess the sites most at risk.

Writing in the Journal of Coastal Conservation and using California's Santa Barbara Channel as a case study, the researchers illustrate how quantifiable factors such as historical rates of shoreline change, wave action, coastal slope and shoreline geomorphology can be used to develop a scientifically sound way of measuring the vulnerability of individual archaeological sites. They then propose developing an index of the sites most at risk so informed decisions can be made about how to preserve or salvage them.

Urban development, the researchers point out, also is a significant threat to the loss of archaeological data. Coastlines have long been magnets of human settlement and contain a rich array of ancient archaeological sites, many of which have never been excavated. Urban development is projected to remain high in coastal areas, representing a significant danger to undisturbed sites.

Thousands of archaeological sites—from large villages and workshops to fragmented shell middens and lithic scatters—are perched on the shorelines and sea cliffs of the Santa Barbara Channel, the researchers point out. The archaeological record is never static, and the materials left behind by one generation are altered by the people and environment of the next. However, increasing threats from modern urban development, sea level rise and global warming are poised to increase this steady pattern of alteration and destruction.

The vulnerability of sites in the Santa Barbara Channel is generally lower than sites located along more open, more gently sloped or unstable coastlines, such as the Atlantic and Gulf coasts of North America.

Measuring threats and identifying vulnerable sites is not an end in itself, the researchers say. "We must find ways to act…by quantifying those sites most vulnerable to destruction, we take a first step toward mitigating the loss of archaeological data and the shared cultural patrimony they contain."

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
