Zhdanov, Michael S. | Integral electric current method in 3-D electromagnetic modeling for large conductivity contrast | Abstract-We introduce a new approach to 3-D electromagnetic (EM) modeling for models with large conductivity contrast. It is based on the equations for integral current within the cells of the discretization grid, instead of the electric field or electric current themselves, which are used in the c... | Electromagnetic modeling; Integral electric current method; 3-D modeling; High conductivity contrast; Integral equations | 2007-05 |

Jewell, Paul | Paleoredox conditions and the origin of bedded barites along the Late Devonian North American continental margin | The most important controls of the redox state of natural waters are the flux of organic matter from the photic zone, the degree of physical mixing, and oxygen concentrations of any connecting water masses. In coastal upwelling zones, these factors can be described with a simple box model constraine... | Bedded barites; Late Devonian; Continental margin; Redox state | 1994 |
