Mekong River flow reconstructed from tree rings

 

The Mekong River is an important transboundary water resource for a large part of southeast Asia. Here, we reconstruct the flow of the Mekong River in its upper and lower basin over the last three centuries using tree-ring chronologies from southeast Asia. Apparently extreme low flow events, like those that occurred in 2010, are not exceptional over the length of the reconstruction. Flow varies on interannual to decadal time scales and shows a recent increase in the lower basin, both of which have implications for future sustainable development in the watershed.

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

Practical Dendroclimatology

Dendroclimatology will place tree rings as natural archives of climate fluctuation in the context of interannual to millennial fluctuations in climate, and of other sources of evidence. The development of tree-ring records for use in the development of climate reconstructions, and the testing and use of such reconstructions will be covered by a mixture of lectures, discussions, practical exercises and student presentations.
