Abstract:
Marine geophysical mapping of the Queen Charlotte Fault in the eastern Gulf of Alaska was conducted in 2016 as part of a collaborative effort between the U.S. Geological Survey and the Alaska Department of Fish and Game to understand the morphology and subsurface geology of the entire Queen Charlotte system. The Queen Charlotte fault is the offshore portion of the Queen Charlotte-Fairweather Fault: a major structural feature that extends more than 1,200 kilometers from the Fairweather Range of southern Alaska to northern Vancouver Island, Canada. The data published in this data release were collected along the Queen Charlotte Fault between Cross Sound and Noyes Canyon, offshore southeastern Alaska from May 18 to June 11, 2016. Data were collected aboard the Alaska Department of Fish and Game research vessel Medeia using a Reson SeaBat 7160 multibeam echosounder. This data release contains approximately 453 square kilometers of multibeam bathymetric and backscatter data gridded at 10-meter resolution. Multibeam water column imagery and seismic profile data also collected during this survey are not published in this data release
Purpose:
The purpose of this grid is to provide a detailed bathymetric terrain model of a portion of the Queen Charlotte Fault and adjacent seafloor. Our goals included determining how fast the two sides of the fault move past each other (slip rate) and deciphering the historical movement of the fault. We also want to better understand how large earthquakes might trigger potentially dangerous underwater landslides.
Supplemental_Information:
The R/V Medeia owned and operated by the Alaska Department of Fish and Game (AKDFG) was mobilized in her homeport of Juneau, AK May 12-15, 2016. Once mobilized the vessel transited to the northern section of the survey area in Cross Sound via the Icy Strait. The survey area covered 453 square kilometers from Cross Sound in the north, to Noyes Canyon in the south and was subdivided into 6 general "Blocks" to facilitate data processing and management. Each Block was 60-75 kms long and approximately 10-12 kms wide.
