A new laboratory of dendrochronology in Valparaíso, Chile: Expanding the tree-ring applications in South America

The breadth of geographic conditions, climatic variations, and dynamics of the landscape of Chile makes Chile a natural laboratory for the use of dendrochronology in several of its applications. In this talk, we will share some of the experiences that are taking place in the new Laboratory of Dendrochronology and Environmental Studies in the city of Valparaíso to study the dynamics of the environment in Chile.

Asst. Dean Vorhees will be viewing the room during this time in preparation for an event.

AED210 Class Visit

Arin Haverland and Randall Smith will host AED210 Students for a hands on course and tour. This class will be using the MP room and then be visiting the upstairs labs.

Tipping point analysis of geophysical data

We apply the tipping point toolbox [1-8] to study transitions and bifurcations in various geophysical datasets. We study early warning and detection signals of the records using methodology that combines degenerate fingerprinting and potential analysis techniques for anticipation, detection and forecast of tipping points in a dynamical system. Degenerate fingerprinting indicator is a dynamically derived lag-1 autocorrelation, ACF (or, alternatively, short-range scaling exponent of Detrended Fluctuation Analysis, DFA [1]), which shows short-term memory in a series.

Probing the Error Term in Streamflow Reconstruction

Water balance models were first applied indirectly by tree-ring researchers in reconstructions of Palmer Drought Severity Index in the mid-1970s. Recent years have seen more direct and explicit use of water-balance models. This talk explores how a simple monthly water-balance model can be applied to diagnose possible causes of large errors in reconstructions of streamflow.
