This is a story of surprises—of a geophysical observatory and a community of scientists who until about a year ago were unknown to scientists in the West, who now have new opportunities for collaboration with expert seismologists in Russia and Kazakhstan.The story began for us in the spring of 1990 at the annual workshop of the Incorporated Research Institutions for Seismology (IRIS), Seismologists from the Soviet Union attended and told us that they had permission to describe a geophysical observatory at Borovoye, near Kokchetav in Northern Kazakhstan, which had operated digital seismometers since 1966. They said there was a large tape archive and that much of the data were of excellent quality and would probably be made available on request—even the data for nuclear explosi

摘要:

The wide interest in the nature and evolution of deep ocean circulation as a key factor to understanding climate change set the stage for a conference devoted to North Atlantic Deep Water (NADW) formation held at Lamont‐Doherty Geological Observatory (LDGO), Palisades, N.Y., from November 11 to 12, 1991. Sponsored by the LDGO Climate Center and hosted by Wally Broecker, about seventy scientists attended. Twenty‐seven invited papers were presented at the 2‐day conference.The rates and paths of NADW formation were the focus of the first day. Bob Dickson, Lowestoft, U.K., summarized the present state of the “northern end” of global thermohaline circulation. In contrast to the view one obtains from many existing numerical models, especially the simpler ones, NADW derives, in reality, from a mixture of distinctly different water masses before it spreads into the world ocean. At most, 50% of the estimated 20 Sv (1 sverdrup = 106m3/s) of North Atlantic overturning actually comes from the Arctic via the overflows east and west of Iceland; the rest is thought of as recirculating water from the Labrador Sea. The Greenland‐Iceland ridge overflow conspicuously lacks both seasonal and interannual variability in the transport. This is an important constraint for future model

摘要:

Here is a proposal for an experimental publication in an area new to AGU.AGU currently has five core publications:Eoscommunicates within the scientific community;Journal of Geophysical Research(all colors and hues) and Water Resources Research are the mainline archival journals;Geophysical Research Lettersfeatures quick, short, and timely publications; andReviews of Geophysicsintegrates current research into coherent overviews. Nowhere does the Union offer a forum for the teaching of geophysics similar in scope to theAmerican Journal of Physics,which, unfortunately, does not cover our territory.

摘要:

A special session, “Snowpack Physics: Processes and Distributions,” was held on December 10 at the Fall 1991 AGU Meeting to survey applications of snow physics spanning scales from millimeters to kilometers, and to tie these in with recent advances in our understanding of the micro‐ and meso scale processes in a snow cover.The first half of the session involved the relationships between snow physical process and properties and remote sensing, snowgas interactions, and snowmelt chem

摘要:

The Karst Waters Institute (KWI) is a U.S. research organization that was formed to combine the skills of academic, governmental, and private sector specialists to solve existing karst water problems and anticipate future problems. KWI has been incorporated as a not‐for‐profit corporation in West Virginia to provide the human expertise and database needed to assist the nation in the preservation and utilization of its water resources.KWI plans to develop a core of resident and visiting scientists from across the nation and overseas, technicians, support staff, and graduate students. Its mission is to conduct research to improve our understanding of karst phenomena, to develop techniques to prevent environmental problems from occurring in karst areas, to assist in rectifying existing environmental problems, and to provide education and training for professionals and the general public on the risks and benefits of karst ar
