Other ID: none
Status: Completed
Organization(s): USGS, Pacific 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): Peter Haeussler (Alaska Science Center)
Information Specialist(s): Peter Dartnell
Data Type(s): Location-Elevation: Navigation, Seismics: Multichannel, Seismics: Sparker, Sonar: Multibeam
Scientific Purpose/Goals: To map the offshore extension of the Queen Charlotte-Fairweather Fault. The fault has produced several significant earthquakes during the last 150 years, yet little to no information exists along most of its length due to its location offshore. We aim to image the fault structure, mode of deformation and constrain its late Holocene slip rate for the northernmost segment.

| Survey Equipment | Survey Info | Data Type(s) | Data Collected |
|---|---|---|---|
| Mini-sparker | --- | Sparker | Multichannel minisparker seismic-reflection data collected offshore Glacier Bay National Park during USGS field activity 2015-629-FA (Multichannel seismic reflection data were collected by the U.S. Geological Survey in May of 2015 outside of Palma Bay, Alaska. Seismic data were acquired coincidentally with high resolution bathymetry.) |
| CodaOctopus F180 | --- | Navigation | Navigation tracklines (These metadata describe navigation tracklines from a 2015 multibeam echosounder survey near Cross Sound, southeast Alaska. The trackline data are provided as a GIS shapefile.) |
| Other | --- | --- | --- |
| Mini sparker | --- | Sparker | |
| Reson 7111 | --- | Multibeam | Multibeam acoustic-backscatter data (These metadata describe acoustic-backscatter collected during a 2015 multibeam echosounder survey near Cross Sound, southeast Alaska. The acoustic-backscatter data are provided as a GeoTIFF.) Multibeam bathymetry data (These metadata describe bathymetry collected during a 2015 multibeam echosounder survey near Cross Sound, southeast Alaska. The bathymetry data are published here as a 32-bit GeoTIFF image.) |
