Field Activity 2018-051-FA

Identifier 2018-051-FA
Purpose 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 successfully deployed from R/V Connecticut.
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.
