摘要:

From the reports in Aristotle(Meteorologia), Seneca(Naturalium Quaestionum), and Pliny(Historia Naturalis), as well as those from the Far East [Keimatsu, 1974], we may assume that auroras were known phenomena even in earlier times. However, for these early centuries the number of dates verified up to now is small. No systematic studies were made for these manifestations in the sky, and they remained puzzles. Some early views on atmospheric optics and other problems of the atmosphere originated with Alhazen, i.e. Muhammad b. al‐Hasan ibn al‐Haitan (about 965–1039). There are some thoughts on the physics of the atmosphere in Albertus Magnus (about 1206–1280), but without specific reference to auroras. In the outgoing Middle Age, from the 11th to the 15th centuries, there are no regular observations of sky

摘要:

I was pleasantly surprised to see the photograph of our Chatanika radar facilty on the cover ofEOS, 60(44) In case anyEOSreaders write to inquire about the facility, I thought I would provide you with some information.The Chatanika facility is an incoherent scatter radar used to perform research on the neutral atmosphere, ionosphere, and magnetosphere. It was established in 1971 with funds provided by the Defense Nuclear Agency. Currently, it is supported primarily by the National Science Foundation, with a number of other agencies (DNA, AFOSR, NASA) also sponsoring research. SRI International (formerly Stanford Research Institute) manages and operates the facility. Scientists representing 29 organizations from throughout the world have performed experiments at Chatanika or have been provided with data.

摘要:

The future of federal funding in the earth and ocean sciences may be entwined in the details of current planning of the ocean deep drilling program for the next decade. Right now, important decisions are being considered by presidential advisor Frank Press that will influence the route by which funding, science, and the search for petroleum along passive continental margins will proceed.Part of the dangers that lie ahead are that the large costs of a program of this magnitude can easily encroach upon lesser, but important, programs. In jeopardy, for example, is a portion of the NSF (National Science Foundation) budget for research in the earth sciences. Cost overruns, inflation, and other priorities are the risks. The science, too, could be easily compromised if the decisions to be made within the next week or two are not the right ones.
