Purpose
|
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 years 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.

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.
