Fwd: [iris-bulk] Post PhD oportunities via bulkmail

by Thomas Lecocq

Hi all, Sorry for cross-posting... But when an MSNoise user is proposing PhD opportunities like this, well, I have to forward this ! Best regards from Brussels Thomas -------- Message transféré -------- Sujet : [iris-bulk] Post PhD oportunities via bulkmail *PhD study opportunities in geophysics at the Auckland University, New Zealand (deadline 1 August) * We present the following PhD projects in geophysics at the University of Auckland. *Deciphering volcano seismic signatures from scaled laboratory models (EQC PhD scholarship)*** Here, we aim to perform unique laboratory experiments on fluid-induced acoustic emissions in a range of volcanic rocks to understand seismic observations atWhite Island Volcano (Whakaari), New Zealand. This project has also a special outreach component to support the Seismometers in New Zealand Schools initiative. For more information on this project, contact Ludmila Adam or Kasper van Wijk, or visit: http://www.env.auckland.ac.nz/people/m-adam *Imaging the subsurface of the Auckland Volcanic Field * The city of Auckland sits atop an active volcanic field. The details of the subsurface structure, however, are unknown. In this project, we aim to image the subsurface from ambient noise recorded on the permanent GEONET network of 3-component seismometers around the city. For more information on this project, contact Kasper van Wijk or visit https://www.physics.auckland.ac.nz/research/pal/2014/05/05/seismic-monitori… *Getting inside the earthquake machine: fine-scale imaging of the Alpine Fault zone (partially funded throught the Royal Society of New Zealand)*** The Alpine Fault produces large earthquakes on average every 330 years, with its last rupture in 1717 AD. This project will provideinsight into fault zone architectureÂ and examine how processes occurring within the fault zone control Alpine Fault earthquakes, by performing systematic measurements of the microstructure and geophysical rock properties with novel laboratory techniques. For more information on this project, contact Ludmila Adam or visit: http://www.env.auckland.ac.nz/people/m-adam The University of Auckland provides PhD scholarships that cover tuition costs and provide a stipend of NZ$ 25,000 (tax free). https://www.auckland.ac.nz/en/for/current-students/cs-scholarships-and-awar… These scholarships are competitive, where successful applicants have normally had a high GPA and have completed an undergraduate in geophysics, geology, physics or mathematics. Research experience (such as an MSc or Honours degree) is required to be accepted in the PhD program. The next application deadline for the scholarships is: August 1^st , 2015. Interested applicants should contact Kasper van Wijk or Ludmila Adam to discuss the projects/application.

Headers, instrument response correction and spectral whitening

by dejikuponiyi＠yahoo.com

Hi Thomas et al., Great work done with the MSNoise package. Installation and processing seem really seamless and documentation was adequate. After running the whole steps, I have a couple of questions: The final cross-correlation (sac) files are missing some of the headers (distance, date, station pair names etc.) which should have been calculated (or included) in the course of the computation (I wrote a short code to update the station table on MySQL with instrument code (BHZ, HHZ etc.), coordinates (X,Y) in DEG ). Is the instrument response correction automatically done if I just supply the instrument types (like BH, HH, EH), considering that the stations are of different instrument types (BH, HH and EH)? If I wanted to run the process without spectral whitening, what would be the best way exclude the process (it might be probably handy to include this option in the msnoise config for future releases)? Cheers, Ayo Sent from Surface Pro
