AKA: Ocean_Starr_2017

Other ID: none

Status: Completed

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

Funding Program(s): Coastal and marine earthquake, tsunami, and landslide active margin field studies (ZP00EQV)

Principal Investigator(s): Daniel Brothers

Affiliate Investigator(s): Nathan Miller (WHSC)

Information Specialist(s): Alicia Balster-gee, Patrick Hart, Jared Kluesner

Data Type(s): Location-Elevation: Navigation, Seismics: Boomer, Seismics: Multichannel, Seismics: Sonobuoy, Seismics: Sparker

Scientific Purpose/Goals: Acquire high-resolution multichannel seismic profiles along the Queen Charlotte Fault System to better understand earthquake and tsunami hazards throughout the SE Alaska region.

Start Port/Location: Seattle

End Port/Location: Juneau

Start Date: 2017-06-27

End Date: 2017-07-26

Equipment Used: YoNav, Other, Multichannel, chirp, Mini sparker, Sonobuoy

Information to be Derived: Fault structure, deformation history, seismic stratigraphy, and assessments of slope stability

Summary of Activity and Data Gathered: Chirp, MCS, and sonobuoy line data submitted to FAD. Collected 3000 km of high-resolution multichannel sparker profiles, 300 km of subbottom Chirp profiles and one 80 km sonobuoy profile.
