AKA: none
Other ID: 2021 Fairweather EXPRESS Cascadia mapping; H13549
Status: Completed
Organization(s): USGS, Pacific Coastal and Marine Science Center, National Oceanic and Atmospheric Administration, Bureau of Ocean Energy Management
Funding Program(s): Other (Other), Coastal and marine earthquake, tsunami, and landslide active margin field studies (ZP00EQV)
Principal Investigator(s): Janet Watt, Jenna Hill
Affiliate Investigator(s):
Information Specialist(s): Peter Dartnell
Data Type(s): Sonar: Water column reflectivity, Sonar: Multibeam, Electro-Magnetic: Magnetics
Scientific Purpose/Goals: Collect multibeam bathymetry, acoustic-backscatter, water-column backscatter, and magnetics data along the slope of the Cascadia margin to fill in gaps in hi-resolution multibeam imagery for subduction zone hazard characterization
Vehicle(s): None
Start Port/Location: Port Hueneme, CA
End Port/Location: Newport, OR
Start Date: 2021-10-20
End Date: 2021-11-09
Equipment Used: Other, multibeam, magnetics
Information to be Derived: bathymetry, seafloor backscatter, water-column backscatter
Summary of Activity and Data Gathered: Fiarweather successfully mapped remaining data gaps within Eel Basin and along the shelf edge. No marine magnetic data were collected, only multibeam bathymetry, backscatter, and water column data. Data will be released through NEIC.
