Homestake Meeting Minutes, 07/27/17

Attending:

Agenda:

• Next Meeting: ???
• Data analysis topics
  • Data corrections, frame production (Gary/Daniel/Pat)
  • Event catalog (Gary/Ross)
  • Radiometer updates (Pat, Andrew)
  • Parameter estimation for Rayleigh and Love (Pat) - presentation?
  • Teleseismic events and Wiener filtering (Daniel, Michael)
  • Very-long-periods (Ross) - potential presentation?
  • Velocity from noise correlations (Daniel): pdf

• Papers
  • Homestake Array Summary paper: pdf
    • Leads: Vuk, Gary, Victor
    • target: Seism. Research Lett., 6000 words, 10 figures.

• Active excitation overview paper
  • Leads: Gary, Ross
  • Others: Victor, Daniel,…
  • Will discuss at the next call.

• Surface Active Excitation
  • Leads: Victor, Boise
  • Others: Gary, Ross
  • Victor will talk to Lee about it. Results exist, have a velocity structure. Might be hard to publish a paper on that only. May need some implication aspect.
  • Gary: should check if Gabe will take the lead on this, may want it for his thesis.
  • Gary: could consider putting some of this into the paper that Ross and Gary are working on. But needs to be discussed.

• Underground Active Excitation:
  • Lead: Gary, Ross

• Parameter estimation for the Rayleigh and Love eigenfunctions (amplitude vs depth dependence).
  • Leads: Pat, Daniel
  • Also contributing: Victor, Vuk, Levi
  • Victor: this is novel, but it might be insufficient for a publication. Maybe enough for a short paper.
  • Victor/Vuk: should think more about it, how it would look on its own vs combining with radiometer.
  • Pat: could also use the eigenfunction measurement for Rayleigh and assume something about Rayleigh field to make preliminary estimates of the Newtonian noise. Should discuss this with Jan.

• Estimating directional and modal composition of the seismic noise. (Pat, Levi, Vuk)
  • Leads: Pat, Vuk, Levi

• Wiener filter application
  • Leads: Jan, Michael

• Teleseismic EQs and near-surface scattering
  • Leads: Daniel, Victor

• Time-variable velocity changes
  • Lead: Victor, not started yet

• Very low frequency harmonics (Ross)
