Description of seismograms and how they are produced by drum recorders and electronic instruments with real-time seismograms for Northern California and Long Valley, California and representative seismograms for types of earthquake activity.
We assess the degree to which a consensus was reached on the flow rate of the well by comparing in situ observations with a time-dependent flow rate model derived from pressure readings taken after the Macondo well was shut in for the well integrity test.
Report presenting the data, automatic interpretations, cross sections, and resistivity maps of direct current electrical soundings at the Amargosa Desert Research Site near Beatty, Nevada using a Schlumberger array.
Study addresses questions and concerns related to limited sand resources along the Louisiana shelf and their implications to long-term relative sea-level rise and storm impacts, using newly acquired geophysical and vibracore data.
Presentation of maps of the seismic properties of North America and the surrounding ocean basins compiled from seismic refraction and reflection data, earthquake studies, and surface wave analyses showing crustal thickness and geologic provinces.
