AKA: none

Other ID: N-1-97-MW

Status: Completed

Organization(s):

Funding Program(s): Recent Submarine and Coastal Landsliding in Sleeping Bear Dunes (MU236)

Principal Investigator(s): Bruce Jaffe

Affiliate Investigator(s):

Information Specialist(s):

Data Type(s): Location-Elevation: Navigation, Location-Elevation: Transects, Seismics: Boomer, Seismics: Sub Bottom Profiler, Sonar: Sidescan, Sonar: Single Beam

Scientific Purpose/Goals: Map the offshore portion of the February 1995 Sleeping Bear Point landslide to better understand the affect of landslides on the coastal system in the Sleeping Bear National Lakeshore, gather information for a slope stability analysis, determine landslide history and framework geology near the Point.

Vehicle(s):

Start Port/Location: Leeland, MI

End Port/Location: Leeland, MI

Start Date: 1997-05-19

End Date: 1997-05-22

Equipment Used: computer, Kleinsidescan, 3.5khz, Geopulse, GPS, bottomtransponder, bathymetry, YoNav

Information to be Derived: Extent of submarine portion of the 1995 landslide, geologic controls on sliding, volume sediment moved offshore during the 1995 and other older landslides, images of slide features.

Summary of Activity and Data Gathered: Ran side-scan sonar in reconnaissance and mosaic modes. Collected subbottom profiles. Collected underwater video to groundtruth side-scan images and to document slide features.

Notes: The following is the beginning of USGS Fact Sheet 020-98. In February 1995, a 1,600-foot stretch of popular beach at Sleeping Bear Dunes National Lakeshore suddenly slid into the waters of northeastern Lake Michigan. The National Park Service (NPS) immediately requested the assistance of the U.S. Geological Survey (USGS) in evaluating the hazard at the lakeshore. To protect the public, USGS and NPS scientists are conducting studies that will help predict when the landslide-prone area will move again.
