Seismic Module

It can be quicker/easier to do certain post-processing functions in the frequency domain.

Time series data is complicated because it is unclear when certain events occur.

Frequency data shows us the power of events so we can write music about it.

Option 4

Change in density over change in time (D/T)

Change in distance over change in time (D/T)

Change in time over change in speed (T/S)

Option 4

Using a super computer to pick all the relevant frequencies and computer Fast Fourier Transforms in order to determine material density.

Sorting through waveforms collected by geophones and reducing noise, isolating signal, and picking desired frequencies in order to create the best possible image of the subsurface.

Taking the data into a recording studio and playing it through geophones to create the song of the subsurface.

Option 4

Density, and Seismic Velocity.

Density, Impedance and Seismic Velocity.

Density and Mineral Content.

Option 4

By using a massive ultrasound housed in a tractor trailer to image in Earth's interior.

By hitting the ground with a big hammer and listening to the sound that it makes.

By sending controlled acoustic energy into the Earth and recording the enery transmitted back from different horizons.

Option 4

An addition problem that turns frequency data into sinusoidal waves.

A rapid algorithm used to convert time data to frequency data.

A transform used in engineering for complex number arithmetic.

Option 4

To use the vibration of loose sediment to locate precious minerals.

The use different interference rates to find buried water mains.

To try and generate an accurate picture of the Earth's subsurface and geologic structure.
