Pre deployment equipment qa

Pre-deployment Equipment QA

  • QA all of your equipment in a controlled, lab environment prior to deployment.

  • Test your recording parameters in the lab.

  • Know your equipment:

    • Be familiar with your installation plan.

    • Practice setting up a station in the lab and in a simulated field environment.


Prepare

Prepare

  • Develop deployment and servicing sheets.

    • Know the metadata you will require before you are in the field.

  • A well stocked tool box is a must.

  • Think spares, especially small items that can be misplaced.

  • Identify and collect the construction materials you will need for your seismic station.

Site Selection

  • Far from human-generated noise (roads and machinery)

  • In a temperature-stable environment

  • Far from the ocean

  • On solid (competent) rock

  • Sky view

  • Good Drainage

  • Secure


Vault site construction

Vault & Site Construction

  • Provide sensor coupling to Earth

  • Protect the instruments:

    • Flooding

    • Temperature fluctuations

    • Animals

  • Secure


Field practices

Field Practices

  • Take comprehensive field notes.

    • If it is not documented, it didn’t happen

  • Take your time.

  • Make sure you will record useful data.

    The “Fort Five”

    • Do you have power?

    • Does the seismometer produce signal?

    • Is your instrument programmed correctly?

    • Do you have timing?

    • Is your data being telemetered or stored on-site?


Monitor your site data

Monitor Your Site & Data

  • Monitor your sensor outputs before you close the vault and/or leave the site.

  • Do a service run within 2 weeks of the initial deployment.

  • Monitor your state-of-health channels.

  • Look at waveforms.
