Thermodynamic parameters in the Earth as determined from seismic profiles

Extracting Seismic Profiles from Background Seismic Signals

The idea of obtaining the seismic trace representing the impulse response at one receiver due to a source at another receiver has discussed by many authors. Jon Claerbout (see e.g. Rickett and Claerbout, 1996; Claerbout, web) introduced the concept to seismology. It has been investigated in the laboratory by Lobkis and Weaver (2001), observed in seismic data by Campillio and Paul (2003), and in...

Thermodynamic constraints on seismic inversions

S U M M A R Y We discuss two types of physical constraints derived from thermodynamics that can be applied during seismic inversions. The first constraint involves assimilating heat-flow measurements in seismic inversions. This can improve seismic models beneath continents, particularly beneath cratons and continental platforms where uncertainties in crustal radioactive heat production and the ...

Seismic Gradiometry using Ambient Seismic Noise in an Anisotropic Earth

Growth hormone-mediated alteration of fuel metabolism in the aged rat as determined from transcript profiles.

Age-related changes in body composition and serum lipids resemble symptoms of adult-onset growth hormone (GH) deficiency. GH treatment has been shown to normalize these changes in both GH-deficient adult patients and elderly subjects. The aim of this study was to identify GH-responsive genes that might mediate positive effects of GH treatment on fuel metabolism and body composition. cDNA microa...

Thermodynamic Foundations of the Earth System

Thermodynamics sets fundamental laws for all physical processes and is central to driving and maintaining planetary dynamics. But how do Earth system processes perform work, where do they derive energy from, and what are the ultimate limits? This accessible book describes how the laws of thermodynamics apply to Earth system processes, from solar radiation to motion, geochemical cycling and biot...
