Scientific Purpose/Goals: Collection of seismic reflection data and cores in Lake Michigan to define the stratigraphy and sediment character of the deposits below the lake floor. The last year's seismic reflection data was used to choose core locations for this cruise and to define areas where new seismic reflection data were needed. New gravity and box cores were obtained at most of the sites that were piston cored or vibracored last year, and a number of new core sites were established. These cores will be used to develop a closely dated record of sedimentation and paleoenvironmental 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.


Start Port/Location: Grand Haven, MI

Summary of Activity and Data Gathered: This cruise was done in two legs: first leg June 13-18 (FA 89015); second leg June 19-22 (FA 89016). FA 89015 collected cores from Sites 1 thru 7, 9, 11 thru 13, 20, 22, and 23; FA 89016 collected cores from Sites 24 thru 31. Box cores: 10; Gravity cores: 8; Seismic tracklines: 14.
