摘要:
The earth's magnetism was a subject of intense interest among America's most prominent scientists in the middle of the 19th century. By 1850 they had helped to create an international network of cooperation for its observation. They had founded three magnetic observatories and were planning a fourth for the fledgling Smithsonian Institution. Yet by the mid‐1860's, none of these observatories remained in operatio

摘要:
Curtis A. Collins joined the National Science Foundation (NSF) in 1972. He has worked diligently and with very considerable effect for the welfare of the academic oceanographic community. He is the ideal program manager. He is tough, but with empathy for proposers; knowledgeable, taking the time to follow up on the progress of grantees; and optimistic and forward looking.

摘要:
Near‐bottom plumes of materials indicative of discharge of metal‐rich hot springs were discovered at sites on the Gorda Ridge by a research team of government and university scientists on a cruise of the National Oceanic and Atmospheric Administration (NOAA) ship Surveyor during May 1985 as part of the NOAA Vents Program. The Gorda Ridge, off northern California and Oregon, is the only seafloor spreading center within the proclaimed 200‐mile U.S. Exclusive Economic Zone (370 km wide) of the conterminous United States and is one of the last oceanic ridges to be explored for metal‐rich hot springs. One reason for this neglect is that the Gorda Ridge is slow spreading, with half‐rates ranging from 1.1 cm/yr in the southern portion to 2.2 cm/yr in the northern portion. Slow spreading centers have not been fully evaluated with regard to hydrothermal activity by many members of the research community, who have concentrated their attention on the faster spreading East Pacific Rise to the south and the Juan de Fuca Ridge to the north of the Go

摘要:
On March 25–26, 1985, with the support of the Office of Naval Research, a 2‐day workshop was held at the Florida State University, Tallahassee, to discuss and summarize the recent developments in modeling of oceanic isolated vortices such as intense eddies and solitary waves. The interest in these oceanic features stems from their ubiquity and large amplitudes. Indeed, they contribute to most of the oceanic motion within the mesoscale range (50–500 km in space and 2–20 days in time) and are believed to control, to a great extent, such important processes as mean circulation, meridional heat flux, and dissipation over basin‐wide scales, without counting their biological and othe

摘要:
After tumbling and spinning in space for nearly a year, a $50 million polar‐orbiting weather satellite has been stabilized and will regain nearly all of its functions, according to the National Oceanic and Atmospheric Administration (NOAA). The rescue of NOAA 8 was aided by a computer program that took advantage of the earth's magnetic field to gradually stop the satellite's gyrations.Technicians at NOAA have recalibrated the satellite's instruments, and asEoswent to press, NOAA expected to resume delivery of earth and atmospheric imagery and measure‐ment data on July 1, 1

摘要:
John Sclater, the 1985 Walter H. Bucher Medalist, is eminently deserving of this award, and it gives me great personal pleasure to present the citation. Walter Bucher'sDeformation of the Earth's Crustwas first published in the 1930s. John Sclater, in the late 1960s, continued Bucher's early work on crustal deformation by analyzing the thermal structure of the crust. Sclater combined heat flow observations with seismic, magnetic, gravity, and bathymetry data to produce his age versus depth and heat flow versus age models for the evolution of oceanic crust. John's contributions on the thickness and deformation of the ocean crust played a significant role in our understanding of plate tectonics.
