摘要:

EDGE is a project initiated by a broad consortium of geologists and geophysicists to use state‐of‐the‐art marine geophysical techniques to study the geologic history of submerged continental lithosphere on U.S. margins. A 2‐year proposal to support commercial acquisition, processing, and interpretation of deeppenetration multichannel seismic reflection data from selected transects identified in the Gulf of Alaska, off the Oregon‐Washington coast, in the northeastern Gulf of Mexico, and off the Mid‐Atlantic region of the East Coast (Figure 1) has recently been funded by the National Science Foundation. Additional monies to support this first phase of EDGE are presently being provided by industry.The purpose of this article is to acquaint the widest possible spectrum of the geoscience community with the genesis, development, and prospects of EDGE, and to solicit continuing input on the most important scientific problems that can be addressed on U.S. margins with modern marine geophysical methods. This input will then be used to develop and continue the E

摘要:

AGU president Don Anderson joined former astronaut Sally Ride and National Aeronautics and Space Administration official Lennard Fisk March 8 in testifying before the Senate committee on Commerce, Science, and Transportation. The three had been asked to speak on the future of the Mission to Planet Earth, proposed both in a National Academy of Sciences report and a NASA study.Anderson was chairman of the National Academy of Science's Task Group on Earth Sciences, which prepared the reportMission to Planet Earthas part of the series Space Science in the Twenty‐First Century. In his testimony, Anderson highlighted parts of the report and quoted the frontispiece “We now have the technology and the incentive to move boldly forward on a Mission to Planet Earth. We call on the nation to implement an integrated global program using both spaceborne and earth‐based instrumentation for fundamental research on the origin, evolution and nature of our planet, its place in our solar system, and its interaction with living things, including man

摘要:

Criteria to identify significant caves on federal land are being developed by the Interior Department's Bureau of Land Management and the Agriculture Department's Forest Service under requirements of the Federal Cave Resources Protection Act of 1988. The departments gave advance notice of proposed rulemaking March 3 and invited suggestions and comments from the public for 30 days.The law requires protection, to the extent practical, of significant caves on lands administered by the Secretaries of Agriculture and Interior and includes authority to issue and revoke permits for collection and removal of cave resources and special provisions for regulation of cave resources on Indian lands. Final regulations must be published by August 18, 1989.

摘要:

The second regional conference of the Front Range Branch, AGU, was attended by more than 80 professionals and some 20 outstanding high school students. The conference included 2 days of interdisciplinary talks, and lots of discussion, that primarily were keyed to geophysical studies of Colorado, Wyoming, and New Mexico. Other talks reported on nonregional, and sometimes global, studies being done by geophypsicists of the Front Range region.Topics included tectonics of the Front Range and the Colorado Plateau, pollution of the Arkansas and Mississippi rivers, and a supreme polluting event that caused the late‐Cretaceous extinctions. Other notable talks were on toxic cleanup, microburst (wind shear) detection at U.S. airports, and other meteorological studies. Several talks treated the audience to the excitement of new work and surprise discoveries. The meeting was multimedia, including the playing of two videos through a projection TV and the playing of a fascinating tape between an airport control tower and incoming pilots during a severe microburst even
