Scientific Purpose/Goals: Collection of seismic reflection data in Lake Michigan to define the stratigraphy and sediment character of the deposits below the lake floor. The seismic reflection data was used to choose final core locations for the second leg of the cruise. These cores will be used to develop a closely dated record of sedimentation and paleoenviromental conditions in the lake. The cores and the seismic reflection data together will be used to determine the history of lake-level fluctuations over the last several thousand years.

Equipment Used: Alpine Vibracorer, ORE 140 transceiver/1036 transducer sub-bottom profiler, Boomer, Benthos AQ-4 10-element hydrophone streamer, Megapulse Accufix 500 LORAN-C, Piston corer

Information to be Derived:

Summary of Activity and Data Gathered: The cruise was generally successful although plagued with mobilization problems and some weather difficulties. Two storms, one of which was the remains of Hurricane Gilbert, forced our return to port. Mobilization for the seismic leg (Leg 1) took 3 days instead of the allotted 2, and the coring mobilization (Leg 2) took 6 days instead of the allotted 2. Nevertheless, a total of 950 km of seismic reflection profiles were collected and 13 cores (6 piston and 7 vibracores) were obtained. Analysis of the seismic reflection profiles and cores should provide sufficient data to begin to decipher the history of changes in lake level in Lake Michigan over the last several thousand years and the lake's response to those changes.
