摘要:
In the wake of last July's failure of the Geostationary Operational Environmental Satellite (GOES 5) weather satellite over the eastern part of the United States, managers at the National Oceanic and Atmospheric Administration (NOAA) are trying to keep the weather data flowing to satellite users around the country. The geosynchronous satellite, one of two GOES spacecraft stationed over American longitudes, lost its imaging capability on July 29 (Eos, August 21, 1984, p. 483).Following the failure, the companion GOES‐West satellite was shifted from its 135°W station to a more central position over the United States (98°W) so as to cover the eastern part of the country as much as possible. Now, says William Callicott, deputy director of NOAA's Office of Satellite Data Processing and Distribution, the lone remaining U.S. geosynchronous weather satellite will be shifted around with the seasons. At the end of this hurricane season, sometime after November 15, GOES‐West (or GOES 6, as it is officially called) will be moved from 98°W to 108°W, where it can better keep watch on winter storms in the northeastern Pacific. Then, in mid‐April, after the tornado season, it will be moved back to the central locatio

摘要:
In December 1883 the U.S. Navy Hydrographic Office, a branch of the Bureau of Navigation of the Navy Department, began to publish monthly Pilot Charts. Earlier, oceanographer M.F. Maury had produced some summary survey charts showing ocean currents, winds, sailing routes, and the locations of whales. The new charts were unique in that they showed updated positions of derelict vessels and other drifting debris. From this series of positions of identified derelicts the first ocean trajectories were obtained. Much of this information has been forgotten during the last 100 years, and good collections of the Pilot Charts are rare. (The only complete collection that I could find is held by the Defense Mapping Agency.) This article is a recompilation and description of these early trajectories and a reminder of the usefulness of the Pilot Charts. It also provides a glimpse of a little known part of maritime history, the last days of wooden sailing vessels.

摘要:
Many aquatic invertebrates are known to form swarms and schools. Thus, zooplankton are usually distributed unevenly both in vertical and in horizontal directions. There are a great number of studies on zooplankton swarms ranging from simple records or observations to more extensive functional and behavioral investigations. Yet, no attempt has been made on mathematically modeling these phenomena, chiefly because of the lack of detailed data on individual movements in swarms.

摘要:
On entering water, light is both scattered and absorbed. The sum of these is attenuation. In the open ocean, the agent of most scattering and absorption is plankton, or plankton‐derived products. The controls, therefore, governing the variability in light absorption and scattering are no less than the controls governing the distribution, abundance, and growth of plankton populations. Apart from being attenuated, light is also generated ubiquitously in the upper layers of the sea through mechanisms of bioluminescence. The overall and long‐term goal of Biowatt is to establish causal links operating between the variability in light attenuation and light production in the ocean. The issues addressed range from behavioral relationships among macrozooplankton and micronekton, to the dynamics of absorbing and scattering populations, to the physical dynamics of the upper layers. A conceptual model is shown in Figur

摘要:
The Ocean Sciences Section of the AGU recognizes W. Stanley Wilson for his unique leadership contributions to the emerging role of satellite measurements in oceanography. Through his persistent efforts the ocean sciences now stand on the brink of a new era that will merge conventional research techniques with new satellite technologies.Stan completed his B.S. and M.A. degrees at the College of William and Mary. He spent three years as a research biologist in Australia, New Zealand, and Antarctica before obtaining a Ph.D. in oceanography from The Johns Hopkins University in 1972.

摘要:
Two “new” ocean‐going research vessels operated by the Scripps Institution of Oceanography and the National Science Foundation (NSF) will soon begin full‐time scientific duties off the coast of California and in the Antarctic, respectively. The 37.5‐m Scripps vessel, namedRobert Gordon Sproutin honor of the ex‐president of the University of California, replaces the smaller shipEllen B. Scripps, which had served the institution since 1965. The new ship is a slightly modified Gulf Coast workboat. Under the name ofMidnight Alaskan, it had been used for high‐resolution geophysical surveys in American and Latin American waters by such firms as Arco Oil&Gas, Exxon, Pennzoil, and Racal‐Decca before its purchase by Scripps from a Lousiana chartering f

摘要:
Since 1977, the National Research Council (NRC) has published 13 monographs in itsStudies in Geophysicsseries. Earlier volumes have dealt with such diverse topics as energy and climate, geophysical prediction, continental tectonics, and explosive volcanism. Groundwater Contamination is the 14th volume in the series. It was produced by a Panel on Groundwater Contamination initiated by the Geophysics Study Committee of NRC in consultation with representatives of the supporting agencies and members of the scientific community. The preliminary scientific findings formed the basis of an American Geophysical Union symposium in San Francisco in December 1981. This monograph is the most concise and most accessible reference available on this important environmental problem.
