Field Activity Details for field activity 2019-032-FA

Other ID: none

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s): Marine Geohazards Sources and Probability (LQ00ENR)

Principal Investigator(s): Nathaniel Miller, Uri Ten Brink

Affiliate Investigator(s): John Collins (WHOI)

Information Specialist(s): Nathaniel Miller

Data Type(s): Seismics: Ocean Bottom Seismometer

Scientific Purpose/Goals: 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.

Vehicle(s):

Start Port/Location: Woods Hole, MA

End Port/Location: Woods Hole, MA

Start Date: 2019-08-29

End Date: 2019-09-03

Equipment Used: Other, Ocean Bottom Seismometer

Information to be Derived: Sediment shear wavespeed

Summary of Activity and Data Gathered: 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%.

Notes: 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.
