Soil data at sites near Geneva Lake, Lake Geneva, Wisconsin, and Long Lake, near New Auburn, Wisconsin
David J. Graczyk, Steven R. Greb
2006, Open-File Report 2006-1191
The goals of this project are to describe how water moves through shallow soil and how vegetated buffers influence this flow. This was accomplished by using a series of soil-moisture probes which track the lateral and vertical movement of water during natural and artificial rainfall/runoff events. The purpose of this...

Inversion of elastic impedance for unconsolidated sediments
Myung W. Lee
2006, Scientific Investigations Report 2006-5081
Elastic properties of gas-hydrate-bearing sediments are important for quantifying gas hydrate amounts as well as discriminating the gas hydrate effect on velocity from free gas or pore pressure. This paper presents an elastic inversion method for estimating elastic properties of gas-hydrate-bearing sediments from angle stacks using sequential inversion of P-wave...
