摘要:

Fluid mass transport controls a majority of the many chemical‐rock reactions observed in Earth's crust. The scale and magnitude of this crustal fluid transport has been considerably extended in recent years. This review summarizes some of the cross‐disciplinary evidence for large‐scale fluid migration in Earth's crust and the proposed mechanisms that may account for its tran

摘要:

The development of models that describe the ocean general circulation and its variability on decadal time scales is the principal objective of the World Ocean Circulation Experiment (WOCE) within the World Climate Research Program (WCRP). Such models are, in conjunction with atmospheric circulation models, essential for the prediction of climate change. To be a credible tool for this purpose, the models not only must be based on established dynamical principles, but also must be compatible with the observed elements of the global circulation.

摘要:

Following the two notes inEoson the recent great earthquake on the Macquarie Ridge (“Labor Pains at Subduction's Birth,” by William Ward Maggs, June 13, p. 650, and “Macquarie Earthquake of May 23, 1989,” by Barbara Romanowicz and Goran Ekstrom, July 11, p. 700), we would like to put the record straight on minor comments in the articles.Tsunami: Indeed, a tsunami was generated and recorded on at least four tide gages along the coast of southeastern Australia, southeast Tasmania and southeastern New South Wales. The peak‐to‐trough amplitude was very small, 0.3 m, barely above the normal harbor seiche at each ot the tide gage sites. The duration of the wave train in Sydney harbor was

摘要:

Redoubt volcano is about 200 km southwest of Anchorage, Alaska, on the west side of Cook Inlet. The current eruption began December 14 about 10 a.m. local time. In 5 minutes the eruption plume reached an altitude of 10.5 km. An explosion December 15 sent one plume of ash and steam to 12 km altitude and another to 8 km.

摘要:

Global‐scale ocean dynamics related to El Niño‐Southern Oscillation (ENSO) was the focus of the 21st International Colloquium on Ocean Dynamics. ENSO provides modelers a great deal of data revealing correlation between sea surface temperature (SST) anomalies and atmospheric pressure differentials in the tropics. (SeeEnfield[1989] for an excellent review of the data.)The meeting was held May 8–12, 1989, at the University of Liege, Belgium. More than 50 scientists attended, from Australia, Belgium, Canada, Federal Republic of Germany, France, Hungary, Italy, Japan, Netherlands, People's Republic of China, Spain, U.K., U.S., and U

摘要:

The Bowie Medal is the highest honor the American Geophysical Union can bestow. It is given for unselfish cooperation in research. No one fits this theme better than Walter Munk. His entire career has been spent in generous cooperation with other scientists, both his students, his contemporaries, and his seniors.
