摘要:

During the Fourth Preparatory Meeting of the U.N. Seabed Committee in July and August, the subject of marine science research became a substantive issue that will be on the agenda for future conferences on the Law of the Sea. Although it is much too early to predict the outcome of international negotiations on this issue, it is already clear that the recommended policy of the U.S. National Academy of Sciences will not prevail. This is not surprising because this policy represents a liberal approach of scientists from a highly developed country, and it cannot be expected that developing nations within the present international political climate will necessarily share this position. In general, the Academy policy favored the maximum freedom of open scientific research in the three zones of jurisdiction that seem to be emerging: territorial waters, an intermediate or resource zone, and the remaining open ocean. It seems unlikely at this stage that within the territorial waters and the intermediate zone future scientific research will be conducted without first obtaining permission from the coastal state. This situation is not insignificant since these areas might constitute as much as 30% of the world ocean. Moreover, there is concern that even on the open ocean, permission for scientific research will require prior approval from some as yet undefined international authority.

摘要:

The measurement and interpretation of strain and tilt in the earth is a topic of increasing geophysical interest, both for the study of earth tides and as a means to study earthquakes and other tectonic processes. In the past few years there has been a great growth in the numbers and types of strain and tilt instruments installed in many parts of the world. The instruments and the resulting measurements were the focus of an excellent discussion meeting organized by A.H. Cook, R.V. Jones, R.G. Bilham, and G.C.P. King and sponsored by the Royal Society in London on May 10, 11, and 12, 1972.The meeting opened with a discussion by A. Cook of periodic and nonperiodic earth strain changes. He pointed out that the existing strain and tilt instruments span a wide frequency range, from seismic waves through free oscillations and earth tides to nonperiodic (zero frequency) deformation. The nonperiodic changes include the steps observed during earthquakes and the long‐term tectonic strains of sea‐floor spread

摘要:

Since the European Earth and Planetary Physics Colloquium (EEPPC) was held at the University of Reading, England, in April 1971, investigations have been made on a multinational basis to establish the practicability of forming a European Geophysical Society (EGS) in response to the following resolutions (1–3) adopted at the Reading meeting.1. An Association of European Geophysicists should be established with individual membership making small annual subscriptions to meet the cost of producing and distributing an information sheet on future colloquia.2. The main activity of the Association shall be to promote the continuation of the European Earth and Planetary Physics Colloquia on an annual basis.3. The practical implementation of the above resolutions shall initially be the responsibility of an Executive Committee, the members of which will be determined after consultations with representatives in the concerned countries of Europ

摘要:

The National Science Foundation has again asked the National Research Council to advise it in selection of candidates for the Foundation's Program of Graduate Fellowships for 1973–1974. Panels appointed by the National Research Council will evaluate qualifications of applicants. Final selection will be made by the Foundation, with awards to be announced on March 15, 1973.Applicants to the Program must be beginning graduate students by the fall of 1973 or must have completed not more than one calendar year of full‐time or part‐time graduate study by the fall of 1973. Subject to the availability of funds, new fellowships awarded in the spring of 1973 will be for periods of three years, the second and third years contingent on certification to the Foundation by the fellowship institution of the student's satisfactory progress toward an advanced degree in the sci

摘要:

The Joint Institute for Laboratory Astrophysics (JILA) is devoted to research, study, and teaching in theoretical astrophysics, low‐energy atomic physics, and other closely related areas. Primary interest now is in the areas of stellar atmospheres, solar physics, stellar stability and the interstellar medium, atomic and molecular collisions, spectroscopy and spectral line broading, and laser physics. Laboratory and theoretical studies conducted at JILA often complement results obtained by observational programs at astronomical and space research facilities.To enable persons actively contributing to these fields to come to the Institute to continue their studies and research, JILA operates a Visiting Scientists Program. In addition to provision of certain facilities to visitors with independent financial support, approximately seven stipends are available each year for Visiting Fellowships. The Visiting Fellowships are normally awarded to scientists with extensive research experience beyond the doctoral degree. An additional Visiting Fellowship in the field of space physics, jointly sponsored by JILA and the University of Colorado's Laboratory for Atmospheric and Space Physics, is availabl

摘要:

An agreement to jointly manufacture the world's first expendable ocean salinity, temperature, depth (XSTD) measuring system has been made by Plessey Environmental Systems and The Sippican Corporation of Marion, Massachusetts. According to news releases thisExpendable XSTD Systemprovides a simple and economical method for obtaining salinity and temperature data as a function of depth from the ocean environment. It is designed for operation to depths of 750 meters over temperature and salinity ranges of −2° to 35°C and 30 to 40 ppt. Applications of the XSTD include ASW, commercial, oceanographic, and fishing investigations.It is reported that in operation the XSTD is quickly and easily launched from a moving ship and that the sensed data are transmitted through a fine wire from an expendable probe to data processing equipment on shipboard. The insulated conductor wire is dual‐spooled, allowing independent dereeling that assures vertical descent of the probe after launch from the deck of a moving v
