Description:

Abstract:

These metadata describe navigation tracklines from a 2015 multibeam echosounder survey near Cross Sound, southeast Alaska. Data were collected by the U.S. Geological Survey (USGS) and the Alaska Department of Fish and Game (ADFG) aboard the ADFG R/V Solstice during USGS field activity 2015-629-FA. The trackline data are provided as a GIS shapefile.

Purpose:

In 2015 the U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center (PCMSC)in cooperation with the Alaska Department of Fish and Game (ADFG) collected bathymetry and acoustic backscatter data near Cross Sound in southeast Alaska using an Reson 7111 multibeam echosounder mounded to the ADFG R/V Solstice. The survey was conducted to map the offshore expression of the Queen Charlotte fault system that runs for approximately 500 kilometers off the coast of southeast Alaska and British Columbia. This was the first in a series of surveys to map the entire offshore component of the fault. The fault system has generated numerous powerful earthquakes in the magnitude 7 and 8 range. This new mapping will help understand the fault's slip rate, earthquake recurrence intervals, and paleoseismic history. These data are intended for science researchers, students, policy makers, and the general public. These data can be used with geographic information systems or other software to identify bathymetric features. These data are not intended to be used for navigation.

Process_Step:

Process_Description:

In May 2015 the USGS, PCMSC mapped offshore Cross Sound in southeast Alaska over the northern section of the Queen Charlotte fault. A Reson 7111 multibeam echosounder was pole-mounted to the Alaska Department of Fish and Game R/V Solstice. The survey line files were imported into Caris HIPS and SIPS software (version 9) for processing. The multibeam navigation trackline files were export from Caris as one GIS shapefile. The shapefile was imported in ESRI ArcMap. The shapefile was edited to remove unimportant attributes.
