Many in the space science community are wondering why NASA administrator Daniel S. Goldin announced a sudden restructuring of the agency on October 15 (Eos, October 27). The shake‐up saw a split in the Office of Space Science and Applications into the office of Mission to Planetary Earth, which will include all the Earth sciences, and the Office of Planetary Science and Astrophysics.The restructuring, he said, is an attempt to align the agency with the new goals, which he outlined in an address to the Space Science and Applications Advisory Board (SSAAC) on November 5. Claiming that NASA's role has never been stated to the public and that Congress does not understand the agency's role, Goldin sought to clarify future directions for the agenc

摘要:

Some energy implications of global warming were targeted in Title XVI of the Comprehensive National Energy Policy Act (HR776), which President Bush signed into law on October 24. Versions of the bill have undergone much debate and revision in both the House and Senate over the past several months.The bill calls for the establishment of an Interagency Coordinating Council, which will oversee reports dictated by the bill. For example, the council will compare alternative policies for reducing greenhouse gas emissions (emission caps, efficiency standards, and emissions trading). The council will be made up of the Secretary of Energy, the Administrator of the Environmental Protection Agency, the Secretary of Commerce, the Secretary of State, the Secretary of the Interior, and representatives of other appropriate federal agencies.

摘要:

An NSF‐sponsored workshop entitled “Low‐Frequency Electrical Precursors to Earthquakes: Fact or Fiction?” was held at the Lake Arrowhead Hilton in California from June 14 to 17. Thirty‐seven scientists participated in a review of past and current experiments that began with a poster session followed by an open discussion. Highlights of research presented at this workshop included seismic electric signals from Greece, precursory changes of resistivity in China, a reassessment of the ULF anomaly at Loma Prieta, and identification of geophysical constraints for mechanisms possibly causing precursory signals.Discussion focused on instrumentation, laboratory studies, definition of anomalous signals, mechanisms, and the significance of correlations between anomalies and earthquakes. While much is still uncertain, some of the precursory phenomena exist and expanded measurement programs are warranted. The participants identified three main guidelines to improve and quantify their attempts to monitor electrical and electromagnetic precursors and to extend their understanding of the mechanisms responsible for the generation of precursor

摘要:

At four sessions on volatile elements in magmatic systems, held at the AGU 1992 Spring Meeting in Montreal, a diverse group of researchers discussed the various roles of volatiles in igneous systems, from the solution of volatiles into silicate crystals and melts to the quantitative modeling of volatile exsolution resulting in volcanic eruptions or formation of magmatic ore deposits. Each session concentrated on one or two topics and began with invited presentations by established experts.

摘要:

Data, data. Who's got the data? Why can't I find them? If I do find them, why can't I get them? If I do get them, why is the format wrong? Why are they printed or published instead of in a computer‐readable medium? Why is it so expensive to get the excerpt I want instead of 1,000 tapes? Why is the documentation missing or incomplete? Why do we spend good science money on data management? What are the National and World Data centers anyway? What can they do for me?There are two responses to these questions—“just because,” or “do you want the short answer or the long answer?” Just because is an unsatisfactory answer, yet it contains a kernel of truth. The long story is sure to glaze the eyes of the reader over, so I will attempt a short discussion. Apologies for tracing ground known to some of you, and for touches of whimsy. An exegesis of data matters calls for imaginative treatment to get your attention at the start to induce you, gentle reader,
