Carbon Cycling of Glaciated Landscapes on Modern and Geologic Timescales: Investigation with Strontium and Carbon Isotope Geochemistry

Description:

The studies presented in this dissertation combine radiogenic and stable strontium isotope ratios (87Sr/86Sr and 88/86Sr, respectively), radiogenic and stable carbon isotope ratios (Δ14C and 13C, respectively), and bulk ion geochemistry to trace the sources and cycling of C in three glaciated environments (New Zealand, Iceland, and Greenland). A primary...

Lithosphere-Asthenosphere Structure of East Asia from Ambient Noise Tomography

Description:

One seismologist’s noise is another seismologist’s signal. What was once disregarded is now routinely processed as dense arrays of broadband seismometers continuously record small amplitude Earth motions, presenting an immense wealth of data. This dissertation presents three projects where ambient seismic noise, generated by ocean wave interactions with the solid...
