Steve Forman at University of Illinois, Chicago to date the length of burial of sand grains in the lake sediment.
The equipment at the University of Toledo for dating the sediment using the 210Pb and 137Cs broke, and the owner did not repair it due to cost and changes in his research focus.
The steps involved in obtaining the sand signal are as follows.
Ceramic crucibles were the dominant vessel for the sediment during this process.
The processing began by recording the weight of the clean, dry crucible.
Some of the field-work was designed to collect information on lake bathymetry and sub-surface stratigraphy of the sediments, but was only partially successful due to the high amount of gas in the lake sediment that prevented penetration of the sound waves.Abstract To reconstruct low lake levels of Lake Michigan, 16 vibracores of lake sediment along the west coast of the Lower Peninsula of Michigan have been collected.The cores have been split and described and sedimentary contacts between wetlands and deeper water sediment are being radiocarbon dated to determine when the Nipissing transgression drown these lakes and estuaries.To remove the sediment from the coring tube, plastic wrap was draped over a piece of sheet metal cut to size.A slit was cut into the sediment from the widthwise middle toward the edge.
