摘要:
A combined continental‐oceanic magnetotelluric (MT) transect of the southern Appalachians orogenic belt has been completed that spans nearly 600 km on land and extends over 1000 km offshore beneath the Atlantic Ocean (Figure 1). The study is revealing the long‐term changes in the lithosphere that occur as active subduction regimes degenerate to fossil regimes, and tests the degree to which the latter are modified by subsequent extension. The electrical resistivity structure of active subduction has been examined by several researchers in recent years [Wannamaker and Hohmann, 1991;Jones, 1993], but here is the first thorough examination of a currently passive, former convergent mar

摘要:
The National Science Foundation is investing in change. Global change, that is.The agency recently awarded $16.8 million in grants to six institutions to study the human dimensions of global changes to the environment. “Population growth, environmental changes, natural resources, public health, technological advances, social organizations, and political and economic shifts are among the critical factors,” says Cheryl Eavey, coordinator of NSF's Human Dimensions of Global Change research program. “By combining research in the natural and the social sciences, we hope to discover ways to better predict the impact of changes on populations and their environ

摘要:
Neil D. Opdyke was awarded the John Adam Fleming Medal at the AGU Spring Meeting Honors Ceremony, which was held in Baltimore, May 22, 1996. The Fleming Medal recognizes original research and technical leadership in geomagnetism, atmospheric electricity, aeronomy, and related sciences. Opdyke was particularly acknowledged for his pioneering work in the use of marine sediments to study the Earth's magnetic field, especially with regard to polarity reversals, and the development of magnetic stratigraphy. The citation and Opdyke's response are given here.
