KV-63 is the first new discovery in the Valley of the Kings since Howard Carter uncovered the tomb of King Tutankhamun in 1922. Not used as a tomb, KV-63 is in fact an embalmer’s cache from the New Kingdom, containing several cons and many items used in mummication and burial. This presentation covers some of the work done by Dr. Otto Schaden and his crew in the seven years since the discovery and initial study of KV-63. See: http://arce.arizona.edu/sites/default/files/ARCE%20Marazzi3%20%282%29.pdf

Archaeology of “Empty Spaces” in the Southern Andes

The highlands of SW Bolivia, NW Argentina, and N Chile are the most arid part of the Andes. In this area, opportunities for human settlement concentrate in deep river valleys, piedmont oases, and to the lowest basins of the Altiplano (highplateau). This environmental structure has resulted in a long-term pattern of discontinuous settlement, with relatively small populations concentrated in favorable areas, separated by vast expanses of unpopulated mountain heights and deserts.

Joint event: Laboratory of Tree-Ring Research and School of Anthropology --- A 2364-year oak chronology for the Aegean and its implications

Forty years of dendrochronological collecting in the Eastern Mediterranean have until now been stymied by the lack of suitable timbers from the 500 years on either side of the Year 1.  Roman buildings have plenty of beam-beds but no preserved timbers.  Recently an enormous $5 billion metro/subway project through downtown Istanbul/Constantinople has provided the missing link: some 4000 oak pilings from a long series of Byzantine and Late Roman docks and other structures.  Three long chronologies, adding up to 1441 years so far, have enabled us to fill a number of gaps and to build a continuo

Climate dynamics during the Medieval Climate Anomaly

Two millennial-length hydroclimatic proxy records from close to the centers of action of the winter North Atlantic Oscillation (NAO) indicate that the Medieval Climate Anomaly (MCA) was characterized by a pervasive positive phase of the NAO. Supplementary Proxy Surrogate reconstructions based on climate model results and proxy data indicate a clear shift to weaker NAO conditions into the Little Ice Age (LIA). Multidecadal NAO variability results in synoptic-scale shifts in surface pressure, wind fields, and precipitation.

Tree-Ring Day

A Gathering for Tree-ring Lab Faculty, Staff, Students, and Friends.

Food and Refreshments provided (breakfast & lunch).

Come learn about the exciting research being conducted at the Laboratory of Tree-Ring Research. Short presentations by faculty, students, and staff will keep you current on research involving tree-ring data in archaeology, ecology, climate, pollution, hydrology, and all aspects of Dendrochronology.

Trees, Climate, and History: What tree rings can tell us about European history, its climatic drivers, and how it is linked to the Southwest

In climate change research, tree ring data can be used to reconstruct regional- to global-scale climate variability, but also to investigate the atmospheric circulation patterns driving this variability.  Furthermore, tree ring records provide an important tool to quantify the impacts of climatic variability and change on terrestrial ecosystem dynamics.
