A new technique is proposed to determine geometrical focusing parameters (sensor-target relative position and satellite position) from SAR data to improve focusing of SAR images. The technique is tested on synthetic and actual Seasat data. The achieved precision of the parameters is estimated to be better than I in 10,000.

The Winter Weddell Gyre Study was an international, multi-disciplinary experiment involving biologists , chemists, oceanographers and meteorologists. The SPRI involvement centred on sea-ice reasearch, involving both our own experiments and a collaboration with other research groups. The SPRI programme involved measuring ice thickness; studying the under-ice topography with an upward looking sidescan sonar; investigating the acceleration, tilt and strain of the ice; deploying Argos buoys; aerial photography ; iceberg tracking; and two acoustic experiments, one to record ambient noise and the other to acoustically measure the ice thickness.

Soc; 72(2): 163-183.

The experimental goals of the Surface Wave Processes Program (SWAPP) and of the Surface Wave Dynamics Experiment (SWADE) are different but complementary. SWAPP is focused on local processes: principally wave breaking, upper mixed layer dynamics, and microwave and acoustic signatures of wave breaking. SWADE is concerned with the evolution of the directional wave spectrum in both time and space, improved understanding of wind forcing and wave dissipation, the effect of waves on air-sea coupling mechanisms, and the radar response of the surface. SWAPP takes a closer look at wave

dissipation processes directly, while SWADE, with the use of fully nonlinear (third generation) wave models and carefully measured wind forcing, provides an opportunity to study the effect of dissipation on spectral evolution. Both programs involve many research platforms festooned with instruments and large teams of scientists gathering huge datasets. The programs are part of a U.S. Navy 'accelerated research initiative.'

In pursuing its research objectives, the U.S. program uses helicopters, Hercules (LC-130) ski-equipped aircraft, motor toboggans, tracked vehicles, hovercraft, research ships, and icebreakers. Large aircraft are universally used to transport personnel to and from Antarctica. Logistic operations of this scale are extremely costly but are an inherent requirement of activities carried out in hostile and remote areas. Antarctic operations are not directly comparable to Arctic operations, because the north polar region has a much milder climate and inhabited centers are in relatively close proximity. In fact, Antarctic conditions are more closely comparable to those that will be encountered in future potential occupation and mining on the Moon and Mars. Future efforts at commercial mineral evaluation and exploitation will need to look closely at the U.S. logistics effort as a possible pattern for their Antarctic operations.

Supported by the U.S. Department of Energy, the state of Hawaii and a number of Pacific rim countries, the Natural Energy Laboratory of Hawaii is using warm surface and cold deep ocean water to generate electricity, grow health foods, raise imported seafood (Maine lobsters), and produce po-

table freshwater, all without any identifiable pollution. Both closed-cycle (operating like a reverse refrigerator) and open-cycle (use of vaporized, warm seawater to turn a huge turbine and cold seawater to condense) systems are under study and both require large supplies of seawater. If the process is profitable (coupling the generation of electricity with aquaculture, and the production of freshwater will make it so sooner), there are many other locations in the world where the technology will be feasible.

Surfactants have been recognized as a possible tracer of urban sewage pollution. Reported here is a new group of pollutants closely related to cationic surfactants that also could be used as a sewage tracer: the trialkylamines (TAMs). Found along with TAMs were long-chain alkylnitriles (LANs).

In January to March 1989 all components of the ecosystem within a two-mile radius of Arthur Harbor were contaminated by petroleum spilled by the Bahia Paraiso . The most effective removal processes were evaporation, dilution, winds, and currents. Sedimentation, biological uptake, microbial oxidation, and photooxidation accounted for removal of only a minor portion of the spill. One year after the spill, several areas still exhibited contamination. Arthur Harbor and adjacent areas continue to be chronically exposed to low-level petroleum contamination emanating from the Bahia Paraiso.

Vast irrigation schemes in several of the Asian republics of the U.S.S.R. have so reduced inflow from the Syr and Amu rivers that the Aral Sea 'is destined to become a small brine lake.' In the last 30 years sea area has declined by more than 40% and volume by 70%. Salinity has increased by a factor of 3. Furthermore, the remaining inflow is highly mineral-laden and polluted with pesticides. The vast salty flats that border what remains of the sea are now the source of great dust clouds, containing sulfates and chlorides poisonous to plants hundreds of kilometers away. Increasing river water mineralization and ill-conceived agricultural practices threaten the future of the agricultural schemes themselves. However, the gravest damage by far has been to the Aral Sea ecosystem itself, and to inhabitants that had lived off the seas's fisheries, now completely destroyed. 'Saving the Aral region and resolving its tangle of ecological, hydrological and socioeconomic problems...will require an entirely new approach' to economic planning.

Field demonstrations support the use of bioremediation treatment strategies for the reduction of hazardous wastes. The Exxon Valdez oil spill in Prince William Sound provided an opportunity for the EPA to field test the use of nitrogen and phosphorus fertilizers in a well-oxygenated environment to enhance oil biodegradation. With Exxon's financial support, two slow-release fertilizers were applied to two oil-contaminated Alaskan beach test sites. Roughly a year later, the results of the test program demonstrate that fertilizers applied to oiled beaches can increase bacterial biodegradation two-to-three fold without any measurable adverse ecological effects, and suggest that this bioremediation technique should be an integral part of oil-spill clean-up strategy.

The massive oil spill in the Persian Gulf, the largest on record, will certainly affect oxygen-producing plants and algae on the seabed, the desalinization plants, and the fisheries; but net long-term effects on the all-important marine habitats at the base of the food chain are less predictable. Although initial reports focused on the oil threat to dugongs, turtles, and wading birds, ultimate damage to the dominant biota-seagrasses and algae and their habitats-wil1 depend on the path of the oil. Shallow water and near surface habitats are known to be particularly susceptible to floating oil; the effect of oil in deeper muds in largely unknown. In general, little can be done to clean up contaminated gulf habitats; the ecosystem there is a highly complex one, and only the passage of time will make it possible to sort out the effects of the many variables involved.

assessment of petroleum resources and potential environmental hazards to their development. Antarct. Res. Ser., Am. geophys, Un., 51:163-174.

There are no known petroleum resources in Antarctica, and scientific information is lacking to adequately assess any undiscovered resources, or the possible environmental hazards to their development. Antarctica covers a vast area, and likely supergiant oil fields of the type to be exploited would be tiny in comparison. Any petroleum resources located in Antarctica will be found by applying techniques and experience gained developing oil fields in other parts of the world, and would therefore be examples of general cases; in contrast, the Antarctic environment and its associated hazards must be considered unique.

Human activities at Australian Antarctic Territory stations have had serious impacts on the limited ice-free land and local flora and fauna. Casey, a re-developed station, is examined with reference to environmental planning and management under Antarctic Treaty obligations and recent Australian environmental legislation. Recommendations include the setting up of an Australian Antarctic Resources Committee responsible inter alia for environmental planning and management, including regional and station management plans and cumulative and environmental impact assessment for all Antarctic operations.

Fishing, particularly in cases where heavy exploitation of fish stock exceeds mortality by natural causes, is exerting demonstrable pressure on both size and age of sexual maturity of individual fish species. Although the matter is highly complex and there are many variables affecting changes within species, there is considerable evidence that commercial fishing has had its effect. Documented cases of various evolutionary pressures created by exploitation are presented for the pink salmon, Onchorhynchus gorbuscha , and the northeast Arctic cod, Gadus morhua. Given sufficient information, it should be possible to effect positive, as well as negative, evolutionary changes in fisheries. (hbf)

The elements of an iceberg utilization scheme are discussed. An 'Icetec' scheme which combines water utilization with power generation via ocean thermal energy conversion would seem to offer the best economic prospect for iceberg use, but many technical problems remain unsolved while fundamental physical processes affecting an iceberg tow have yet to be examined experimentally.

of Antarctic Mineral Resource Activities. Antarct. Res. Ser; Am. geophys, Un; 51:259-271. After >5 years of negotiations, the Consultative Parties to the Antarctic Treaty reached agreement on the text of the Convention on the Regulation of Antarctic Mineral Resource Activities in June, 1988. This Convention provides for Regulatory Committees to make crucial decisions for miners through a Management Scheme (dealing with financial obligations of Operators, performance requirements, enforcement, etc.) whenever a resource is identified for possible development. These Regulatory Committees will receive non-binding advice from the Scientific, Technical, and Environmental Advisory Committee. Since decisions about mineral resource activities must not violate principles designed to protect against serious damage to the environment, the Convention represents a major step forward in environmental protection. The Convention also includes rules about liability as well as procedures for the settlement of disputes. Law School, Univ. of Western Australia, Nedlands, Perth, WA 6009, Australia.

One of the most important issues raised at the 13th Consultative Meeting of Contracting Parties to the London Dumping Convention held in London (fall, 1990), was future strategy. While there has been a good deal of concern about the effectiveness of the LDC, with many believing there is a need for changes, few agree on the specifics of such changes. The role of scientific information in decision making is of concern as is the increasing tendency for politics to intrude on discussions. The need for

adopting a 'precautionary approach' toward environmental damage, and for increasing the scope of the Convention-particularly whether the LDC should also cover marine internal waters-will be discussed in 1991. Further, the question of pollution from land-based sources will be referred to the UN Conference on Environment and Development with the recommendation that it be addressed by a global instrument.

The essays here are 'first-hand accounts, by regular contributors to Nature, of visits to Antarctica...[which] provide a sense of the flavor of Antarctic research.'

Environmental impacts of exploiting mineral resources and effects of tourism in Antarctica. Antarct. Res. Ser; Am. geophys. Un; 51:237-258.

The time when Antarctica's nonrenewable resources will be exploited is near, so it is prudent to review the impact such activity may have on the environment. The complete loss of any land forms, soil types, and terrestrial biota seems remote, though the cold desert lakes may be a possible exception requiring special protection. Similarly, the complete loss of anyone species of birds and marine mammals is improbable owing to their widespread distribution, though use of the Specially Protected Areas concept would offer additional assurance. In general, present knowledge suggests there is no scientifically sound basis for banning resource development, if enough precautions are taken to minimize environmental damage. At present, there is not enough information about biologically important interactions to make the necessary management and policy decisions. But the fact that Antarctic ecosystems will recover slowly from any damage shows the need for caution. Dept. of Biol., Virginia Polytechnic Inst., Blacksburg, VA 24061, USA. (wbg)

Important work in geophysical fluid dynamics will in the future continue to be motivated by the realization that serious attempts to interpret observations of ocean s, atmospheres and magnetic fields, to formulate crucial field experiments, and to provide a satisfactory theoretical underpinning to practical activities such as weather forecasting, will be inseparable from progress in ba sic research on dynamic and magnetohydrodynamic processes in rapidly rotating fluids. An important area of fluid dynamics which has direct implications for research on planetary interiors is the study of convection in fluids of high and variable viscosity . The dynamics of tenuous plasmas lies at the heart of magnetospheric studies. Supercomputers will facilitate research in all these areas and their availability will be crucial to some of them.

In all aspects of oceanography and geophysics , climatic changes , be they cause or effect , will be the principal focus of studies in the coming decade. The international global biosphere change program of ICSU is a testimony to the realization of the strong links between many branches of geophysics and oceanography, and the effects of this coupling on the global climate. There seems the possibility that realistic coupled atmosphere-ocean-continent models can be developed in the coming decades and that suitable high precision global scale data will be available to test them.

This article examines the quality of scientific writing using a methodology based on the concept of reader expectations. Key to the approach is the idea that information is interpreted more easily and uniformly if it is placed where most readers expect to find it. The information that begins a sentence establishes for the reader a perspective for viewing the entire sentence, yet the misplacement of 'old' and 'new' information in a sen tence (thereby disrupting flow and linkage) is the premier problem in American professional writing. The authors demonstrate a number of rhetorical principles that can provide clarity in communication without overs implification. The improvements are not merely cosmetic; improving the quality of scientific writing may improve the quality of scientific thinking. The seven structural principles: (I) follow a grammatical subject as

The evolution of these concepts, from the possibility of a contracting earth to the hypothesis of convection currents in the earth as underlying causes of mountain building and other geodynamic processes, are presented in retrospect. Special attention is devoted to the connection between Vening Meinesz' ideas and their relevance for the plate tectonic hypothesis. Yening Meinesz stood at the threshold of modern earth science.

Effects of the huge oil spill in the Persian Gulf on the Arabian Peninsula, where most drinking water is obtained from desalination, are likened to 'the inconvenience experienced in some California cities during the region's drought.' A review of the literature on desalination reveals that 60% of the world's desalination capacity is located in Persian Gulf states, where per capita supplies comparable to those of U.S. urban areas are produced using multistage flash distillation and reverse osmosis. Measures regularly used to reduce pollution and fouling would reduce hydrocarbons remaining in the seawater after preliminary treatment. The cost of producing potable water from seawater is calculated to be $4 per 1000 gallons; additional measures to reclaim moderately polluted water using reverse osmosis techniques would add an additional 50 cents per 1000 gallons of water.

Observations of Arctic hurricanes, and a numerical model used to investigate similarities and differences between these storms and tropical hurricanes, are discussed. Arctic hurricanes are particularly intense, rapidly-developing cyclonic storms which form in the cold air masses north of the Polar Front. Arctic hurricanes form along Arctic fronts-air mass boundaries formed in the spring where very cold air collected over pack ice intersects warm marine air over the polar sea. The resultant baroclinic instability is the same mechanism that provides the primary energy source for midlatitude cyclones. If a pre-existing disturbance of sufficient magnitude is present, an Arctic hurricane is initiated. The storm is characterized by a cloud-free 'eye' of sinking air surrounded by a symmetric wall of convective cumulus clouds, fueled by energy flux from the sea surface. In these respects Arctic hurricanes are very similar to their tropical counterparts. Much remains

Problems with the hypothesis of J. Martin et al., that low iron levels may be the cause of low algal productivity in certain nutrient rich areas of the ocean, are discussed. Experiments suggesting alternatives to the iron limitation hypothesis are briefly summarized (upwelling effects, preferential uptake of ammonium) and problems with bottle incubation experiments are pointed out. Fertilizing the ocean with iron, thereby stimulating photosynthetic removal of CO2 from the atmosphere, does not seem to be 'even a partial cure for the greenhouse effect.'

Research has revealed that schooling is common, not only to fish, but also to some crustaceans-mysids, decapods, cladocerans, and copepods. In the past, it was believed that these schools were merely transient groups of individuals brought together by wind current or wave action, but careful observation shows that the schools are maintained under a variety of conditions, even in rough seas. Schooling has the evolutionary advantage of providing protection from predators, and the schools have developed a series of defense maneuvers for this purpose. In addition, schooling may also facilitate finding food and create social and reproductive opportunities not available to individuals traveling alone. Univ. of Tasmania, Australia.

In 1980 the National Acid Precipitation Assessment Program (NAPAP) was created by the U.S. Congress to guide it on policy questions, and requirements, costs and benefits of various acid rain control strategies. But when Congress finally acted last year, it did so without much help from NAPAP. Its multimillion-dollar computer models were not completed and neither was the long-awaited 'integrated assessment.' But NAPAP had spent $500 million,

and 2000 scientists had studied the problem to death. What went wrong? The conclusion is that 'NAPAP strove for scientific perfection, but lost policy relevance in the bargain....That fundamental failing...may be repeating itself in the new federal climate change program,' coordinated by the interagency Committee on Earth and Environmental Sciences.

A general, non-technical summary is presented of the findings to date of the Joint Global Ocean Flux Study (lGOFS), a lO-yr program within the International Geosphere Biosphere Programme. The study began in 1989 and has been concentrating on algal productivity and sedimentation rates in the North Atlantic. The ultimate goal is to use models to understand the physical and biological processes controlling carbon fluxes in the ocean utilizing data from satellite measurements combined with information on sea conditions, cloud cover, etc. Significant new findings from JGOFS include data on the unexpectedly complex nature of the spring phytoplankton bloom, and the effects of vertical migration of zooplankton. Our knowledge of the effects of marine productivity on climate during the ice ages, and our current understanding of carbon dioxide fluxes, are briefly summarized. NERC Biogeochem.

also spotlights the young, gloved male scuba diver with a specific objective (lobstering, etc.) as the person having the most negative interactions with the coral. Snorkelers stir up huge clouds of sediment that settles on the corals causing them to produce a defensive mucus, adding stress that in time may exhaust them. The solution lies in more education such as that engaged in by the underwater police force at Key Largo's National Marine Sanctuary (which hands out $25 Enforcement Action Reports), the cooperation of commercial dive shops and dive boat captains who forbid the wearing of gloves.

'Dolphins are complex creatures, strongly social, that possess acute problem-solving skills, have long childhoods filled with many learning experiences, and are capable of a great deal of intraspecies and interspecies cooperation. Even though we can't discuss Plato with them, there is still a lot they can teach us.' These three articles discuss dolphin 'smarts'; the use of dolphins for interaction therapy with such groups as autistic children; and news items pertaining to dolphins' welfare, such as their military use by the Navy, and their entanglement in tuna nets.

Comets are potentially powerful indicators of conditions during early solar system history, and even pre-solar history, for a good deal of their bulk probably consists of preserved, relict interstellar matter. There have now been six spacecraft encounters with two different comets, 'vastly expanding our knowledge of comets.'
