Field Activity 2017-621-FA

Identifier 2017-621-FA
Also known as Ocean_Starr_2017
Purpose Acquire high-resolution multichannel seismic profiles along the Queen Charlotte Fault System to better understand earthquake and tsunami hazards throughout the SE Alaska region.
Location Southeastern Alaska continental slope
Summary 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.
Info derived Fault structure, deformation history, seismic stratigraphy, and assessments of slope stability
