摘要:
Southeastern Canada and the western United States were unusually dry during water year 1987, which ended in September 1987. The Great Plains, from North Dakota to Texas, were wet, as were isolated areas in the deep South. U.S. Geological Survey (USGS) hydrologists report that 55% of the streamflow stations that they monitor in the contiguous United States and Puerto Rico showed normal flow during the year. Nearly 30% of the stations were unusually dry.

摘要:
Major developments have emerged in the field of ecology as a result of taking a long‐term approach to both basic and applied research [Strayer, 1986]. In recognition of both the advantages of long‐term research programs and the historical difficulty of sustaining such research efforts, the National Science Foundation (NSF) instituted its Long‐Term Ecological Research (LTER) Program in 1980 [Callahan, 1984]. The LTER Program has a number of important links with the geosciences and is likely to play a significant role in work on terrestrial, freshwater, and estuarine ecosystems within the International Geosphere‐Biosphere Program (IBGP); it is thus a good time for us to begin communicating with geoscientists who are helping to sha

摘要:
The Coupling, Energetics, and Dynamics of Atmospheric Regions (CEDAR) program is an international cooperative effort within the aeronomy community to further our understanding of Earth's upper atmosphere [Romick et al., 1987]. This program will be high‐lighted by numerous multi‐instrument measurement campaigns, and global simulations of the magnetosphere‐ionosphere‐atmosphere system. The results obtained from these studies promise a great leap forward in our understanding of the physics and chemistry of the atmosphere. To achieve these results, however, will require the ability to access large amounts of data from many different instruments and

摘要:
This third volume of the Cambridge Studies in Modern Optics is a comprehensive and authoritative treatise on the design, construction, and analysis of measurements from these multiple‐beam instruments. Its treatment of the Fabry‐Perot interferometer is highly mathematical and unified, weaving together in a coherent and consistent format the work of over 400 different authors. The author is well qualified to discuss these topics, having used these devices to study the dynamics of the upper atmosphere for the past 25 years. During this time he has made several fundamental contributions to interferometry, in addition to aeron

摘要:
A 2‐day symposium was held at the Lawrence Berkeley Laboratory (LBL) on March 17–18, 1987, to review a large body of scientific investigations for the Long Valley Caldera and to discuss concepts and models for the present‐day magmatic‐hydrothermal system. Speakers at the symposium also addressed the problem of where to locate future scientific drill holes in the caldera.Deep scientific drilling projects such as those being contemplated by the U.S. Department of Energy (DOE) Geothermal Technologies Division (GTD), under the Magma Energy Program, and by the DOE Office of Basic Energy Sciences (OBES) along with the U.S. Geological Survey (USGS) and the National Science Foundation (NSF), under the Continental Scientific Drilling Program (CSDP), will be major and expensive national undertakings that will require strong support from geoscientists and engineers and from industry and government‐supported laboratories. DOE/OBES is sponsoring a program of relatively shallow core holes (less than 1 km) in the caldera, and DOE/GTD is considering the start of a deep (6‐km) hole for geophysical observations and sampling of the near‐magmatic environment as early as fiscal y

摘要:
The International Association of Hydrological Sciences (IAHS) awarded its 1987 International Hydrology Prize to Vujica Yevjevich, preseritly Professor Emeritus at Colorado State University (Fort Collins). The award was announced at the IAHS General Assembly final plenary meeting in Vancouver, Canada, on August 21, 1987.Because Yevjevich was unable to attend the Vancouver meeting, the prize —a beautiful silver medal— was presented to him at George Washington University, Washington, D.C., on September 11 by two IAHS representatives. Ivan Johnson (A. Ivan Johson, Inc., Arvada, Colo.), Honorary President of IAHS, and Marshall Moss (U.S. Geological Survey (USGS), Reston, Va.), Chairman of the U.S. National Committee for IAHS, personally handed the medal to Yevjevich. On behalf of the IAHS membership, they offered congratulations on the award and appreciation for Yevjevich's many contributions to the science of hydrology. (See photograph abo

摘要:
The session on general groundwater at the AGU 1987 Fall Meeting included several interesting presentations. In this report, the papers have been grouped into four categories for the ease of discussion: groundwater management, aquifer compaction, field approaches, and modeling.
