PREFACE 
This report presents the results of a joint research effort by the U.S. 
Army Coastal Engineering Research Center (CERC) and the Lake Erie Section, 
Ohio Department of Natural Resources (ODNR) Division of Geological Survey 
(DGS). The objective of the research effort was to devise and test light- 
weight vibratory coring devices which could be deployed from a small vessel, 
9.1 to 18.3 meters long, characteristic of the type generally available to 
Corps of Engineers District agencies and to other organizations engaged in 
sediment studies of coastal and inland waters. The work was carried out under 
CERC's Barrier Island Sedimentation Studies work unit, Shore Protection and 
Restoration Program, Coastal Engineering Area of Civil Works Research and 
Development. 
The report was prepared by Jonathan A. Fuller and Edward P. Meisburger, 
geologists of DGS and CERC, respectively, under the general supervision of 
Dr. C. Carter, Chief, Lake Erie Section (DGS), Dr. C.H. Everts, Chief, Engi- 
neering Geology Branch, and Mr. N. Parker, Chief, Engineering Development 
Division, CERC. The design and the laboratory testing of the coring device 
were done by Meisburger at CERC. Field testing and modifications were done 
by Fuller in Lake Erie using the DGS research vessel GS-1. 
The authors acknowledge the assistance of the following people: C.D. 
Puglia, CERC, who assisted in designing the coring frame; J.D. Jackson, CERC, 
who built the coring device; D.L. Liebenthal, DGS, who skippered the boat 
and assisted in the coring; C.L. Hopfinger, DGS, who assisted in the boat 
work; and T.C. Welch, ODNR, Division of Wildlife, who provided most of the 
PVC core tubes. 
Technical Director of CERC was Dr. Robert W. Whalin, P.E., upon publica- 
tion of this report.
