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.

Got Help?
|
For 89016, we would appreciate any information on -- analog materials, contract, days at sea, dive count, funding, information specialist, kms of navigation, national plan, NGDC Info, owner, scanned materials, seismic description, station count, station description, submersible, tabulated info.
