The Missouri to Massachusetts Broadband Seismometer Experiment
Entry ID: PASSCAL_MOMA

[ Update this Record ]

Summary
Abstract: In the MOMA experiment, 18 broadband seismometers were deployed
between permanent IRIS/GSN stations CCM (Cathedral Caves, Missouri)
and HRV (Harvard,Massachusetts), providing a linear 20-station array
spanning 1740 km. The goal of the experiment was to obtain new
information about the structure of the core-mantle boundary (CMB), the
structure of the crust and mantle beneath the eastern U.S. (including
mantle discontinuities, mantle anisotropy, and lateral velocity
variations), and the structure of subducting lithospheric slabs.

SEISMOMETERS Ancillary Description
Quality Please note that the CMG-3T instrument responses in the data archived
at the DMC were incorrect through August of 1998. All instrument
responses are now correct.

Data gaps related to low station power occurred at many
sites,particularly during the winter months due to snow and ice
accumulations on solar panels. Data gaps due to DAS failures were not
uncommon.
Access Constraints None
Use Constraints Please cite the data properly.
