New Roles for an Old Resource
Ferromanganese Nodules Assist Mine Cleanup
by Eleanora Iberall Robbins
Eliminating manganese from acidic discharge water is a serious problem for many Appalachian
coal companies. In an urban wetland only minutes away from Washington, D.C., a researcher
from the U.S. Geological Survey has been studying manganese fixation in an environment that
has a natural capacity to remove toxic substances and metals from through-flowing water.
Geoscience and Law --
Strange Bedfellows or Interdisciplinary Teambuilding?
by John M. Stafford
Lawyers practicing environmental law, natural resources law, or intellectual property (patent)
law typically find themselves explaining geoscience concepts before a judge and jury or to
government officials who lack even fundamental knowledge about science. An attorney with a
Denver-based law firm describes new communication tools that are helping to bridge the
technical-information gap.
Implications of Carboniferous Cyclic Rhythmites
by Allen W. Archer
Cyclic rhythmites have interesting implications in the study of sequence stratigraphy, reports a
sedimentary geologist at Kansas State University. Rhythmites containing seasonal cycles not
only provide detailed information on ancient climatic variability but influence studies of the
evolution of the earth-moon system.
