Field Activity 2015-629-FA

Identifier 2015-629-FA
Purpose 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.
Location Southeastern Alaska, offshore Glacier Bay National Park

Dataset name Equipment Description Dataset contact
Multichannel minisparker seismic-reflection data collected offshore Glacier Bay National Park during USGS field activity 2015-629-FA Mini-sparker 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. Daniel Brothers
Navigation tracklines CodaOctopus F180 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. Peter Dartnell
Multibeam acoustic-backscatter data Reson 7111 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. Peter Dartnell
Multibeam bathymetry data Reson 7111 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. Peter Dartnell
