OBSIP Cascadia Data User Survey

The Ocean Bottom Seismograph Instrument Pool deployed the Amphibious Array as a part of the Cascadia Initiative from 2011 through 2015. We are interested in collecting user experiences with our instrumentation and the resulting data in an effort to ensure that issues are identified and addressed for future experiments and to guide future fleet investments or improvements.

Please take a few moments to provide feedback on your experience using data generated from these instruments to help us improve our fleet and facility in the future.

Question Title

* 1. Are you using the seismic data collected during the Cascade Initiative?

Yes

If yes, please indicate what frequency band(s) you are using?

Question Title

* 2. Are you using differential pressure gauge (DPG) data?

Yes

Note any issues or comments regarding differential pressure gauge data.

Question Title

* 3. Are you using absolute pressure gauge (APG) data?

Yes

Note any issues or comments regarding absolute pressure gauge data.

Question Title

* 4. Are you using strong motion data?

Yes

Note any issues or comments regarding strong motion data.

Question Title

* 5. Do you use horizontal component seismic data?

Yes

Note any issues or comments regarding horizontal component OBS data.

Question Title

* 6. Are you using temperature gauge data data?

Yes

Note any issues or comments regarding temperature sensor data.

Question Title

* 7. Have you identified any significant differences in the performance of shallow water vs. deep water instruments?

Yes

Explain

Question Title

* 8. Did you detect seasonal difference in the performance of the instruments?

Yes

Explain

Question Title

* 9. Please describe any specific benefits of the focused array your research employed. The focused arrays were the densely-spaced stations deployed in North Cascadia for Year 1 and Year 3, and South Cascadia at the Mendocino Triple Junction for Year 2 and Year 4.

Question Title

* 10. Have you identified any specific performance characteristics of any particular models of instrument?

Yes

If yes, please explain

Question Title

* 11. Did your research use land instruments?

Yes

If so please elaborate on how those stations aided your research. Please note if there were specific issues and how they compared to seafloor stations.

Question Title

* 12. Was the level of timing accuracy provided by OBSIP instrumentation sufficient for your research?

Yes

If not what level of timing accuracy is required?

Question Title

* 13. Did timing errors affect your research of Cascadia Initiative data?

Yes

Please explain specific timing issues.

Question Title

* 14. Were instrument calibrations correct?

Yes

If not, please note any specific issues.

Question Title

* 15. Did you encounter any issues with OBS station metadata?

Yes

Please explain any issues

Question Title

* 16. What aspects of the Amphibious Array OBS instruments would you keep the same?

Question Title

* 17. What aspects of the Amphibious Array OBS instruments would you change?

Question Title

* 18. In your opinion, what is the most compelling research result from the Cascadia Initiative? Please feel free to cite papers/authors.

Question Title

* 19. If you are interested in discussing your experience with Amphibious Array instrumentation deployed in Cascadia and would like to participate in a focus group aimed at making improvements to that instrumentation, please provide your contact information:
