Current QEC project:  Search for Solar L=2 G-Modes in IU QSPA seismometer data


The work around searching for Solar L=2 G-Modes in seismometer data began in 2013 using data from the IRIS Consortium ( ).  The goal of the project was to determine if Gravity Waves generated within the Sun by L>=2 G-Mode oscillations could be detected using seismometer data on the Earth.


Results to-date are positive and the first paper is in the peer review process in Astrophysics with the American Astronomical Society (AAS).

Title:  Detection of Quadrupole Gravitational Effects Generated by Solar G-Modes using Earth Based Seismometers


Abstract:  Seismometer data from the QSPA location near the South Pole are analyzed for mode periodicity to detect L=2 G-Modes generated by the Sun. Solar G-Modes having L _ 2 are expected to generate near _field gravitational effects and/or gravity waves. The estimated Solar L=2 gravity wave amplitude in seismometer data is 0.3-1.7 nm at 1 AU. The L=1 mode is not observed in the seismometer data, where none is expected for gravitational radiation. Analysis of seismometer data from 6/2004 to 7/2016 indicates a primary L=2 G-Mode with an asymptotic mode separation of 14:193 +/- 0:696 minutes, which is consistent with model calculations. This analysis documents both the existence of solar gravitational oscillations in earth based seismometer data as well as a method for studying those oscillations.


Technical notes:

1.      All data used in this study is publically available from the IRIS network.

2.      The data were downloaded from IRIS using the BreqFast utility ( ).

3.      SAC and other software from IRIS were used for unloading SAC files and computing instrument responses.

4.      All data used in this study was VH*, having a sample rate of 10 seconds.  The VH* data was chosen over the UH* data because more was available…. 11 years of VH* data for this study.

5.      Actual East-West and North-South components of seismometer data were obtained by rotating VH1 and VH2 data after instrument response using the azimuth found in the SAC headers for each SAC file used.

6.      The project has involved a great deal of software development in 3 environments.

a.      Java:  Using Eclipse Luna for the current IDE ( )

b.      Mathematica:  For plotting and general data analyses (

c.       Maple:  Implementation of the Dyson tensor analysis for modeling ( )

7.      The earthquake catalog used in earthquake removal from time series was obtained from the USGS.



Michael J. Padgett   would like to thank Mark Spearman (Factory Physics, Inc.) for many conversations and assistance with284 this project (including the solar altitude code that was recoded and used in modeling Sax et al. (1991)) and Dana B. Padgett for great support, including detailed editorial assistance. Freeman Dyson (IAS, Princeton) has provided valuable insight with 3 very good suggestions for follow-up work and Frank Krennrich (Physics, Iowa State University) made very useful  suggestions. Thanks for great access and support are also offered to the Rice University Fondren Library and its very helpful staff.  All of the seismometer data used in this study are available from the IRIS consortium, along with a great deal of support software, IRIS DMC (2016) and Goldstein (2005). The help and support system of the IRIS consortium were crucial for this project. The earthquake data used in seismic data preparation is produced by and available from the USGS at its earthquake archive.



Exploration Geophysics,  Historical work:  Quantum Earth’s style of fluid contact analysis


The Quantum Earth focuses on fluid contact analysis from 3D seismic data.  The approaches used at Quantum Earth involve both horizon and volume based calculations.  The emphasis is on objective, quantitative analysis.


Analysis has been performed successfully at >4.0 Sec using both land and marine 3D seismic.


The variation in fluid contact morphology between seismic time / depth and well depth is taken into consideration.


"Non-flat" flat spots are treated and handled for detection.


Fluid contact analyses can be performed either on full volumes for prospect generation or on a single prospect analysis basis.




Exploration Geophysics,  Historical work:  Quantum Earth’s technology is proprietary


The technology developed at Quantum Earth is proprietary.  It is being used primarily for prospect generation on a proprietary basis.  The various software components listed below have been licensed to a limited number of companies.


In the process of developing technology, Quantum Earth is actively pursuing technology that can be protected.  Currently, Quantum Earth has been awarded 6 patents.  Final numbers have been issued for 5.  One is awating a final number issuance.  Additionally, one patent is still pending review in the US and several abroad are in the process.  The Quantum Earth trademark has been awarded.


Software has been written to implement:

·         Horizon Binning 2D

·         GrAZ both 2D and 3D for flat spot analysis

·         Dipstack analysis for 3D flat spot analysis

·         3D flat spot vector derived filtering for 3D flat spot analysis

·         AVO outlier scanning using locally adaptive windows

·         Segy Clustering for usage in scanning as a pre-interpretation step with workstation loading

·         Segy Header scanning for file verification

·         Segy utilities including very flexible copying for volumes and gathers.


All software is currently being written in Java (running on 1.6 or above) with concurrency handled by the Java Concurrent package.

Gui's have been designed that are basic and not overly complicated with reasonable defaults for most parameters.  The Java help facilities have been used in several modules for user support and documentation.  Eclipse is used at Quantum Earth as the development IDE.  The codes have been verified on Windows, Linux, Solaris 9 and Solaris 10.





Exploration Geophysics,  Historical work:  Quantum Earth is qualified to hold leases in the Gulf of Mexico


Quantum Earth has gone through the process with the MMS (US) become qualified to bid-on and to hold leases in the Gulf of Mexico.  This will allow the company to pursue options in upcoming lease sales or other acquisitions.
