The first oceanographic cruise to the Strait of Magellan in 1988-89 to investigate the structure of water bodies and sediments in the strait was followed by a second the following summer to complete the surveys, examine channel systems, and carry out a seismic survey. The contents of this volume are based largely on observations dating from the first cruise, but take into account subsequent discoveries. The reports treat the plant landscape; seismic survey results, hydrological characteristics, paraffinic hydrocarbons in the water; phytoplankton, microzooplankton, copepod assemblages, suspended particulate matter; bottom sediments, magnetic susceptibility and geochemistry of surficial sediments, sedimentological processes; distribution of heavy and light sands; and the morphology, sediments, and thermohaline features of the channels. A sedimentological chart provides a summary of the data and their preliminary interpretation. (hbf)

This atlas and explanatory text were compiled under the sponsorship of the Division of Polar Programs of the National Science Foundation. Relatively little interpretation has been incorporated into the synthesis beyond that implicit in the publications used, that inherent in the various analyses procedures required, or that required to reconcile apparently discrepant data or interpretations. This series of maps does, however, represent considerably more than a compilation of published results. The maps incorporate extensive new and unpublished geological and geophysical data as well as many invaluable data that have appeared previously only in the gray literature. The atlas includes maps of bathymetry, gravity, magnetic anomalies, sediment thickness, and type and crustal structure, tectonics and age.

The proposal of Radojevic and Tressider (1992) to dispose of flue gases (especially sulphur dioxide) in the ocean is objected to on the grounds that it would release carbon dioxide to the atmosphere (as the sulphur dioxide oxidizes to sulphate); and, in a separate comment, on economic grounds. Radojevic admits there are problems to work out, but still feels that seawater is a suitable receptacle for sulphur dioxide. (fes) 92:6516 Korotenko, K.A., J99O.

The evidence is that destructive building habits, especially the miles of high-rise buildings that mar the East coast from New Jersey to Florida, were fostered in the first place by 1968 laws that made federally subsidized insurance possible. Today, the owner of beachfront property valued at about $200,000 pays a mere $950 a year for flood insurance. On the open market, a similar policy would cost more than $18,000, assuming that private insurers would be willing to take the risk at all. New development would essentially come to a dead halt; nature would be the real beneficiary. But it may be too much to hope for the repeal of this foolhardy law. The political influence of the real estate lobby, not to mention that of home owners, is not to be underestimated.

This paper examines the significance of paleoclimate studies in forward-modeling of climate change. The relationships among atmospheric composition, climate and biological communities gleaned from the geological record are examined in terms of their relevance to human-induced environmental change. The most valuable information comes from the Quaternary record of change due to the similarities in geography, general climate and biota. Topics covered include greenhouse gases and climate warming, water-balance changes, feedbacks involving sinks and sources and biological community effects. In general it is thought that significant understanding of the global response to anthropogenic perturbations can be obtained by increasing our present understanding of Quaternary climate shifts.

J. oceanogr. Soc. Japan, 47(4):126-137. Optical properties and the biological--ehemical composition of suspended matter in the aoshio water were investigated using nearby 'normal' coastal water as a reference. Suspended matter in the aoshio water contributed to the large beam-attenuation coefficient and also to the strong upward radiance. No significant difference in bacterial density was observed between aoshio and coastal water. Suspended particles in aoshio water samples had much higher content of Sand Mn and a lower Si content than those in coastal water samples. It may be concluded that there is a high probability that elemental Sand Mn-rich particles are responsible for the color and turbidity in aoshio. Abiko Res. Lab., Central Res.

Hydrogenous ferromanganese crusts are a common feature of oceanic seamounts, forming slowly through precipitation from seawater, by a process producing crusts of thicknesses up to 240 mm. The present study of recruitment by sessile invertebrates to ferromanganese crusts and basalt on Cross Seamount, North Pacific Ocean, July 1988 to February 1990 supports the view that hydrogenesis alone may not adequately account for crust formation. Here, mediation of crust growth by benthic Foraminifera and inhibition of ferromanganese oxide precipitation by high abundances of sessile macrofauna are suggested as two interactive biological processes relevant to crust accretion.

Bell, D.R., 1992. Water in mantle minerals. [Report.] Nature, Lond., 357(6380):646-647. New experiments by Bai and Kohlstedt (1992) indicate that the hydrous component of olivine, which is a major mineral constituent of the Earth to depths of 400 km, remains stable to temperatures of 1300°C at the relatively low pressures of uppermost crust, and hence shows considerably greater thermal stability than most hydrous magnesium silicates. Other researchers at Caltech have found small, but widespread, quantities of hydrogen bound in the hydroxyl groups in common anhydrous mantle minerals, which could prove to be important reservoirs of hydrogen in the Earth's interior. Before these findings can be applied to models for the evolution of the Earth's interior and reactions within the mantle, data is needed to establish the effects of higher pressures on the solubility of H in olivine and other mantle sources.

find ings present an 'accounting problem' when ice-age CO2 values are reduced by either biological pumping mechanisms or ocean circulation changes. If ice-age air-sea exchange fractionization was much more effective (e.g., by a combination of increased low-latitude pumping and decreased high latitude productivity) then predicted CO 2 and 813C values are closer to those found in the proxy records. It is hard to expla in low ice-age CO 2 solely in terms of carbon-fractionating mechanisms. OEOMAR, Christian Albrechts Univ., 2300 Kiel 14, FRO. (Ijw)

Two competing hypotheses on the limiting of SST in the western tropical Pacific are examined. One theory , the 'thermostat' hypothesis, contends that surface heating is limited by the formation and shading effect of anvil clouds. The other hypothesis contends that evaporative cooling limits SST with or without cloud formation. The authors conclude that available observational data are at variance with the 'hot patch' hypothesis and indicate just the opposite-warming of surface waters in the central equatorial Pacific is apparently accompanied by decreased evaporation. Although it is premature to extrapolate the regional cloud 'thermostat' hypothesis to global warming, the radiative-convective link established in this hypothesis may be an important clue in the global climate puzzle.
