AKA: Santa Cruz Harbor survey post tsunami

Other ID: none

Status: Completed

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

Funding Program(s): Tsunami Hazards, Modeling, and the Sedimentary Record (ZP00ES5)

Principal Investigator(s): Bruce Jaffe

Affiliate Investigator(s):

Information Specialist(s): Peter Dartnell

Data Type(s): Sonar: Interferometric

Scientific Purpose/Goals: Map Santa Cruz harbor and offshore to identify any bathymetric change following the tsunami generated by the 2022 Tonga volcano eruption

Vehicle(s): Mitsubishi Outlander G61-0912R

Start Port/Location: Santa Cruz, CA

End Port/Location: Santa Cruz, CA

Start Date: 2022-01-26

End Date: 2022-01-26

Equipment Used: SWATH plus-M

Information to be Derived: bathymetry and backscatter

Summary of Activity and Data Gathered: Swath mapping of Santa Cruz Harbor to document tsunami erosion/deposition (if any) from the tsunami generated by the 2022 Tonga volcanic eruption. This bathymetry may be used in the future for modeling of tsunami in the harbor.
