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...
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...
