摘要:

The chemistry of marsh sediment is profoundly affected by seasonal cycles, including desiccation of the sediment in summer and the growth of vegetation. In this article, we examine the relation of these processes to the transport of natural and fallout radionuclides in sediment.

摘要:

I would like to take this opportunity to summarize the state of the Hydrology Section of AGU as I see it after 4 years in the trenches (2 as President‐Elect and 2 as President). The picture I will paint is a relatively rosy one. I believe the section is healthy and performing its primary functions well with respect to publications, meeting, and awards. The section has also been involved in some special programs and issues that may be of interest to you. In this brief report, I will try to hit the highlighh in each of these areas, closing with mention of the minor but nagging ongoing problems that in my opinion arise largely from a need to grapple with the dichotomies of our sectio

摘要:

The Flow Regimes from Experimental and Network Data (FREND) project was established in 1985 in the United Kingdom to undertake a 3‐year project as the major contribution to Project 6.1 of the Third Phase of the International Hydrological Programme (IHP). The project was initiated by IHP with the objective of analyzing hydrological data from small research and national network basins to study the natural and man‐made hydrological regimes. Although a number of individual basin studies have previously been carried out in the study area of northwest Europe, there have been few attempts to compare results from different countries or to provide techniques for generalizing or extrapolating research results beyond individual catchment boundaries. FREND seeks to overcome this deficiency by applying statistical analyses and modeling techniques to a large European data b

摘要:

A special session entitled “Aggregation and Disaggregation Processes” was held at the 1985 AGU Fall Meeting, December 9–13, in San Francisco, Calif. The purpose of the session was to bring together individuals interested in topics of aggregation and disaggregation to discuss the state of the art and new developments in these areas including their potential integr

摘要:

Recent letters in Forum by Ron Zwickl (Eos, April 15, 1986, p. 186) and C. T. Russell (Eos, July 1, 1986, p. 545) have addressed the proliferation of authors on papers in AGU journals. I assume that the authors have at least theJournal of Geophysical Research‐Space Physicsin mind, as both are frequent contributors to our journal (and highly valued referees as well!).There is no doubt in my mind that marginal participants sometimes end up in the bylines of papers we publish. In a few instances, I do not believe that all authors even read the final manuscript: if they did, they would exercise better quality control over the submitted product. I do not agree, however, that AGU should be responsible for determining authorship, even in a tangential way: its concern, manifest through its editors, should be that each article published represents a significant new contribution to the discipline. To me as editor, it's what comes after the byline that matter

摘要:

The November special issue ofGeophysical Research Letters(GRL) is dedicated to research on a troubling scientific mystery: the annual decrease in atmospheric ozone levels over the south pole in September and October, commonly called the “ozone hole” (Eos, October 28, 1986, p. 812; June 17, 1986, p. 524). Papers in the GRL issue present evidence both supporting and casting doubt on virtually every ozone hole hypothesis proposed so

摘要:

Three seismic refraction profiles will be shot in central Alaska in 1987 by the U.S. Geological Survey (USGS) as a continuation of work on the USGS Trans‐Alaska Crustal Transect (TACT) project. USGS invites interested parties to collaborate in recording the explosions in this experiment. In addition, seismic refraction data collected in 1984 by USGS in southern Alaska are now available, to be followed soon by the data from 198

摘要:

L. Jeff Lefkoff, a hydrologist with the U.S. Geological Survey (USGS; Menlo Park, Calif.) and doctoral student at Stanford University (Stanford, Calif.), has been selected as the 1986–1987 AGU Congressional Science Fellow. A member of AGU's Hydrology Section, he will begin his 1‐year tenure on Capitol Hill as AGU's 10th Congressional Science Fellow in January.At USGS and Stanford, Lefkoff has conducted research on the hydrologic and economic consequences of various options in water resources policy, especially the use of open markets for water rights. His work for USGS has included development of a computer model, intended for public distribution, for general groundwater management. He has used this model to design aquifer restoration systems and to analyze their hydrologic and economic performa
