摘要:
Three geophysicists have been named National Science Foundation Visiting Professors. They are among 27 scientists and engineers selected by NSF for the 1989–1990 Visiting Professorships for Women program.VPW participants do advanced research and teach at host institutions. They also guide and encourage women interested in research careers. VPW activities at the host institution, such as special seminars or publications, increase awareness of students and faculty of the contributions of women scientists and engineers to the nation's scientific effort and demonstrate to students, especially women, opportunities for careers in science and engineerin

摘要:
There have been numerous articles inEosand elsewhere recently that discuss the cause of the mass extinctions at the Cretaceous‐Tertiary (K‐T) boundary. Clark Chapman's interesting article on the Snowbird II meeting (“Snowbird II: Global Catastrophes,”Eos, April 4, p. 217) is one of the latest. I suppose that few geoscientists would quarrel with his principal conclusion that an association has now been established between the extinctions and the impact of large meteorites, although many paleontologists remain troubled by the inability of a single extraterrestrial impact to account for the complexities of the longdrawn‐out extinctions of the various species.My main concern, as an igneous penologist, is the omission by Chapman of any significant reference to the Deccan basalt eruptions, the most frequently suggested alternative cause of the climatic changes that produced the extinctions [Officer and Drake, 1985]. This is now known to have been an extraordinary volcanic event, both in its rate of eruption and in its total volume. Furthermore, the eruptions occurred, as closely as radiometric techniques can define, exactly at the K‐T boundary. Barring an unlikely coincidence, these eruptions, unique in the last 100 m.y., must surely be related to the equally exceptional worldwide extinctions. This suggestion may be seen as an unwelcome complication to an otherwise satisfactory explanation for the extinctions. Yet, if we accept Chapman's conclusion that the extinctions are probably the result of meteorite impact, then we should also accept, at least as a working hypothesis, that meteorite impact, continental flood basalt eruptions, and the extinctions are interconnected [Alt et al., 1988;Basu et

摘要:
The annual meeting of the Canadian Geophysical Union was hosted this year by McGill University in Montreal, May 17–19. Scientists from across Canada and around the world presented 179 papers in three concurrent sessions over the 3‐day period. Following a schedule of alternate stand‐alone and joint meetings, the CGU met this year in a 1‐day overlap with the Geological Association of Canada and the Mineralogical Association of

摘要:
A healthy and effective space program is of critical importance to many field of geophysics. The proposed Space Station, including polar orbiting platforms and a manned station, would have a substantial impact on this nation's space program. For this reason, the American Geophysical Union has established a position on the Space Station.By vote of the AGU Council during the week of July 21, AGU has formally adopted a position on the Space Station, given below. AGU members who wish to be active in determining the Space Station's future may use this consensus position statement. The panel that drafted the statement was Brad Hagar, chairman, Eugene Bierly, Rafael Bras, Charles Drake, Thomas McCord, James Van Allen, and Gary Ernst.
