Grand challenges in geomagnetism and paleomagnetism

Geomagnetism and paleomagnetism is a broad sub-discipline of the Earth Sciences. I present the Grand Challenges from the perspective of a paleomagnetist and rock magnetist, hence I feel more comfortable with the paleomagnetic side of this short article than the geomagnetic side. Nevertheless, exciting things are happening in geomagnetism and the future is bright for both paleomagnetists and geo...

Characterization by Sampling and in Situ Testing – Connecticut Valley Varved Clay

Varved clays, which consist of alternating layers of silt and clay, are common in glaciated regions of North America and Northern Europe. This layering results in several unique engineering properties making varved clays a challenging soil for engineering design. Varved clays have hydraulic conductivity and undrained shear strength anisotropy that far exceeds that of most other soils. The stren...

Neural Networks Based Lithology Identification

In this paper, a novel neural networks based lithology identification approach is proposed. First, the logging curves are squared so that the noise is filtered off. Second, consecutive segments representing similar stratums are merged so that the dimension of inputs is reduced. Third, data sampling from different logging curves are respectively normalized so that the curves of small magnitude a...
