MOMA: Broadband Seismometer Array Data from Missouri to Massachusetts

The Missouri to Massachusetts Broadband Seismometer Experiment deployed 18 broadband seismometers between two permanent stations, forming a linear 20-station array spanning 1740 km. The experiment, conducted by SCIOPS, aimed to study the core-mantle boundary, crust, mantle, and subducting slabs beneath the eastern U.S. The dataset was last updated in April 1996.

Use Cases

• Modeling the structure of the core-mantle boundary based on seismic array data.
• Analyzing crust and mantle structure beneath the eastern U.S. based on broadband seismometer readings.
• Investigating mantle discontinuities and anisotropy using the linear station array.
• Studying lateral velocity variations and subducting lithospheric slabs from the experiment's data.

Strengths

• Data from a linear 20-station array provides a controlled spatial profile.
• The array spans 1740 km, offering coverage across a significant geological transect.
• 18 broadband seismometers were deployed, suggesting high-resolution time-series data.

Limitations

• Last updated 1996-04-12 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
