Reconstructing Klamath River Flow with Uncertain Instrumental Records: a Mathematical Tale of Passion, Deception, and Desire

Tree-ring based reconstructions of streamflow variability are useful to water resource management. A challenge when developing reconstructions is assessing multiple uncertainties and how these uncertainties impact use in resource management. The skill of tree-ring reconstructions greatly depends on the quality and availability of tree-ring data and the instrument records used for reconstruction training and testing. This presentation will touch on the impact of potential uncertainty in instrumental records with an emphasis on streamflow reconstructions in the Upper Klamath River basin.

Tree-Ring View of “Nameless Oscillation” in California Streamflow

An ongoing severe drought in California highlights the importance of understanding and predicting multi-year swings in moisture availability on the scale of large watersheds.  The 20th and early 21st centuries have seen large oscillations with an average period of about 15 years in annual flows of the Sacramento and San Joaquin Rivers, two major sources of water supply for the state of California.  A meeting sponsored by the California Department of Water Resources (CADWR) was held in La Jolla, California, this past May specifically to address hydrologic and climatological aspects of the rh

From cell to continent: introducing our new cambial phenology project

Our aim is to fill important gaps both in the scientific basis for the use of tree rings as natural archives of past climate and in the scientific understanding of the rates and patterns of carbon storage in annual growth layers in relation to seasonal to inter-annual climate variation. These gaps concern the basic natural history of the tissue that forms annual rings in wood, the vascular cambium.
