[OBSIPtec] OBSIP Functional Specifications Available

[Brent Evers]

Rob - 

Thank you for taking the time to review the functional specs and provide feedback.  This is exactly the type of response and input we are hoping the functional specifications continue to generate.  Your input is very valuable to us and will be logged for discussion and possible inclusion in future revisions of the Functional Specifications.


OBSIPtec - 

An important aspect of Rob's response that others should consider and include in future comments or suggestions is the scientific justification of the requirement.  Knowing not just ‘what’ the community wants but 'why' they need it really helps OBSIP prioritize the long list of technologies and advancements that are under consideration.

The most important benefit from my point of view would be the ability to accurately determine/model focal mechanisms for microearthquake studies. If the orientation of the sensors is known then the amplitude ratios between  SV and SH phases can be used to constrain the focal mechanisms, which is essential for events with non-double-couple mechanisms - i.e., if the orientations are not known it is not generally possible to constrain non-DC events.

>> The OBSIP Oversight Committee has developed functional specifications for OBSIP instrumentation intended to guide the facility in future OBS development.  These functional specifications also provide visibility into the instrumentation requirements necessary to meet current and future science investigations to other groups including vendors, partner facilities, and users.

>> The functional specifications are forward looking and do not represent the current capabilities of the OBSIP fleet, but rather, the desired capabilitites.  Furthermore, these functional specifications are subject to change at any time.  Any feedback regarding their adequacy, or changes required, is welcomed - please contact the OBSIP Oversight Committee Chair.

>> The functional specifications are divided into three instrument types - broadband, short period and short period long duration, and are accessible via the following page on the obsip.org <http://obsip.org/> website:
