This activity will deploy an array of 6 intermediate period ocean-bottom seismographs (OBS). The OBS will record ambient seismic noise for ~6 - 12 months. The ambient noise will be used to measure sediment shear wavespeeds. Shear wavespeed is a proxy for shear strength, a key parameter in controlling slope stability.
Equipment or personnel only. Data, if any, are managed under a different field activity.
Location
Atlantic Ocean
Summary
Six ARRA intermediate period ocean bottom seismographs were recovered from the continental rise just north of the New England Seamounts. Data recovery was nearly 100%.
Info derived
Sediment shear wavespeed
Comments
Instrumentation: 6 WHOI ARRA-type ocean bottom seismographs
Note that this field activity is for an instrument deployment only; No data will be retrieved until the instrument recovery.
