摘要:
Campi Flegrei (Phlegrean Fields) is a Holocene caldera located west of the city of Naples in an area of regional extension [Finetti and Morelli,1974;Scandone,1979]. The erupted products range in composition from K basalts to alkali trachyte and phonolite. The complex has been active since at least 47,000 yr B.P. [Capaldi et al.,1985], and it is surrounded by three other quaternary volcanic centers.

摘要:
The remarkable levels of public health and safety enjoyed by the urban populations of the developed world are due in considerable part to investments in hydrology over the past century. While we have spent lavishly to cope with the scarcities and excesses of water, we have invested little in the basic science underlying water's role in shaping and reshaping our planet. Hydrology, the science of water, has a natural place alongside oceanography, meteorology, geology, and others as one of the geosciences; yet in the modern science establishment, this niche is vacant. Why is this?

摘要:
An all‐day Union session at the upcoming AGU Spring Meeting will provide a forum for discussing the present‐day advances and the new syntheses that may soon be possible through study of the earth as a system. According to session chairman Raymond A. Price of the Geological Survey of Canada (Ottawa), the goal of the session is to bring together speakers from a wide range of disciplines “to share some of the excitement that is being generated [through global studies] and to stimulate some synergism.” The “Earth as a System” session will be held on Tuesday, May 19, at the Baltimore, M

摘要:
The National Oceanic and Atmospheric Administration (NOAA) is in the midst of a year‐long effort to improve the accuracy of a computer model that will be used in predicting airflow and the movement of acid rain‐producing compounds across the eastern half of the United States. A specially instrumented NOAA research aircraft is making a series of flights during a 1‐week period this month to gather air samples and meteorological data along a 1600‐km flight path parallel to and about 200 km west of the Mississippi River. The same series of flights, originating from Little Rock, Ark., was made in February and will be repeated during July and October, according to Joe Boatman of NOAA's Air Resources Laboratory in Boulde

摘要:
According to current concepts, the composition of the atmosphere is largely determined by dynamic processes. The atmosphere represents a geochemical reservoir through which the elements are cycled by an exchange of matter with the oceans and with terrestrial surface waters and soils. Much of the exchange is mediated by biological processes, so that the biosphere is an important source of atmospheric constituents. A typical atmospheric cycle of an element such as sulfur or nitrogen begins with its release into the air as a volatile compound, usually in chemically reduced form. Thereafter the compound undergoes transport and chemical transformation within the atmosphere, but eventually the element is returned to the earth's surface by precipitation scavenging and dry deposition. The natural cycles of atmospheric sulfur and nitrogen are now massively perturbed by an additional emission of huge quantities of SO2and NOxassociated with the combustion of fossil fuels for energy production. It is thus necessary to study the unperturbed atmosphere in more detail in order to assess the impact of anthropogenic emissions upon remote atmospheric regions.

摘要:
The Second Continental Scientific Drilling Program Workshop took place June 12–14, 1986, on the campus of the South Dakota School of Mines and Technology in Rapid City. Like the workshop held in Houston a year earlier, the Rapid City workshop was sponsored by the Department of Energy (DOE), the National Science Foundation (NSF), and the U.S. Geological Survey (USGS). The NSF portion of the Continental Scientific Drilling Program (CSDP) is administered by a consortium of 36 universities through a nonprofit corporation named Deep Observation and Sampling of the Earth' Continental Crust, Inc., or more simply, DOSEC
