Description
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.
