The tremendous advances of the oil companies in well-logging have great potential for the Ocean Drilling Project. Here a conference on such techniques, held at Lamont-Doherty Geological Observatory (May, 1985), is recapped. Briefly covered are borehole instrumentation for neutron activation analysis, nuclear magnetic resonance, ultrasound, and seismology. Combined with analytical, tomographic and imaging algorithms, such techniques yield chemical composition, lithology, fracture locations, dip and bedding planes, shear wave velocities, attenuation coefficients, and stress fields--with nary a look at the material.

Computer graphics have opened many new technological avenues for the display of visual data. However, little is known about human graphical perception, and thus about the most psychologically efficient means for packing and presenting such information. Recent experiments of the authors with graphical perception are reviewed, the outgrowth of which is a preliminary identification and ordering of the main tasks involved in graphical decoding.

The possibility that radar sea return observed using a Ku band fan beam Doppler airborne scatterometer flown over crude oil artificial spills might have been back-scattered via the second-order Bragg interaction is surmised. An attempt is made to justify the absence of the first-order Bragg term. Ist. di Fis. Gen. dell'Univ., Torino, Italy. 86:1274 Fiscella, B., P.P. Lombardini, P. Trivero, P. Pavese and R. Cini, 1985.

A formula is first given for the error in a 2-harmonic seasonal curve of best fit through a set of oceanographic data points, assuming the departures from the true mean are independent random numbers. Departures of actual oceanographic measurements from the mean seasonal cycle are in fact correlated with one another, owing to long-period nonseasonal variability; hence the error estimate from the formula will generally be too small. If the data set can be split into two statistically independent sets, a method estimates the factor by which the formula should be multiplied to account for the effect of correlations on the error estimate. Analyses suggest that the results are reasonably independent of the method of splitting. CSIRO Div. of Oceanogr., Hobart, Tas. 7001, Australia. 86:1276 Gordon, H.R., R.W. Austin, D.K. Clark, W.A.

The tip of a scanning tunneling microscope rastered across a surface traces out the surface profile by registering and being corrected for the magnitude of a tunneling current induced between the materials. Insofar as the profile has dimensions the same as individual atoms or molecules, it is the latter, in fact, which are being seen; thus the location and composition of adsorbed molecules may be pinpointed.


While there are practical difficulties with vibrational surface spectroscopy (much of the experimental work is coming from IBM research facilities) STM is likely to join the analytical arsenal. (fcs)

Ellis Horwood Limited, Chichester; 455pp. This volume, designed to introduce oceanographers to an exciting new research tool and to acquaint sensor technologists and remote-sensing specialists with the fundamentals of oceanography, has also been written for the senior undergraduate/postgraduate in oceanography or remote sensing. The first section is a broad review of satellite remote sensing from the oceanographer's viewpoint with chapters on space possibilities (space hardware and data transmission), oceanographic possibilities (sensor capabilities, dynamic oceanographic processes), remote sensing principles (sensor calibration, atmospheric correction, etc.), and image processing. The second section examines oceanographic applications of remote sensing in greater detail and contains chapters on ocean color scanners, infrared sensors, passive microwave radiometers and microwave altimeters. Four chapters on measuring waves and surface roughness discuss the interaction between radar and the ocean surface, and principles and applications of altimeters, synthetic aperture radar, and the scatterometer. The final chapter looks to the future in remote sensing satellites (ERS-I, TOPEX), upcoming developments in data analysis and new trends in ocean science.

Shelf Sci., 20(4) :431-445. Comparison of discharge-time curves using the two techniques reveals a similar pattern of discharge over time with peak ebb discharge exceeding peak flood discharge and peaks reaching similar values. However, the volumetrically modelled discharge predicted an earlier reversal of the tide and an earlier ebb peak discharge. It is implied that the water surface is not horizontal at all tidal stages and that water surface slopes develop on the ebb tide resulting from inertial effects in restricted channels and on the mangrove-covered mudflats. The volumetric model is therefore inappropriate for the calculation of tidal flux, especially where this is used to calcuate budgets of sediment or organic matter. The velocity-area method estimates discharges in excess of those predicted volumetrically. The disparity probably results from estimating discharge using only one station in the cross-section and is similar to errors of estimating discharge observed in other studies. North Australia Res.

The SWATH ship offers an extremely stable platform (less motion-induced fatigue and sickness); a large, flexible, and accessible deck area; and the capability of maintaining course and speed in higher seas than a comparably-sized monohull (shorter transit times).

While this type of ship does have some disadvantages (it's ill-suited for hauling heavy, high-density loads), its strengths are thought to outweigh its weaknesses for oceanographic researchers, largely because of its superior seakeeping abilities.

Radionuclides and stable element measurements along with species and biomass analyses were made for water, plankton, nekton, sediment and benthic organism samples, and although low biomass and high Actiniaria Sr-90 and Cs-137 were observed at the 1967 site, deep-sea fish radionuclide levels were low in comparison to those


of the North Sea (a commercial fishery).

Once disposal is initiated, the strategy requires sampling the upper mixed layer at 36 stations, mostly within 100 km of the site, and deployment of near-bottom sediment traps along a line extending 300 km from the site. Based on initial results, subsequent sampling locations will be selected to refine estimates of the extent of sludge-derived contamination. Constituents which can be used to detect sludge in water at a dilution of 106, and in sediment traps when diluted by 100 with natural material, include zinc, PCBs, coprostanol and spores of Clostridium perfringens, Other synthetic organic compounds may prove to be useful tracers.

Sewage sludge disposal is discussed in the context of regulations at both the national (the Marine Protection, Research, and Sanctuary Act, also known as the Ocean Dumping Act) and international (the London Dumping Convention) levels. Although dredged spoils and industrial wastes represent a major input, this review concentrates on sewage sludge because its dumping is on the increase, reduct,~on of its contaminants is possible through pretreatment, and a legal-political controversy presently surrounds the issue. The article deals with both the operative regulations and their interpretations, recent developments, and proposals for amelioration of the dumping problem.

As there are factors operating against the recruitment of young talent (the use of short-term contracts in research appointments, etc.) and other research shows that a scientist's peak research years may be between 36 and 40 (so scientists need to start young), Britain may face a shortage of scientific talent and accomplishments in ten years or so.

An unmanned submersible was used to observe and analyze sediments at two sites: one with continuous natural gas seeps and one with pockmarks, presumably the result of episodic gas release. At both sites CH 4 and higher hydrocarbons were detected and fauna was enriched. Different organisms were dominant in the pockmark sediment, which consisted of hard rock (carbonate cement-bound sand, silt, and shell). Thermogenic gas is proposed to migrate upward to the sea floor and through Quaternary sediment (bypassing or escaping traps), and to be altered by degradative and oxidative processes in mini-reservoirs, resulting in a mixed gas (thermogenic and biogenic).

Space-based measuring systems and better understanding of measurement errors are rapidly bringing scientists closer to claiming detection of continental drift. Very Long Baseline Interferometry can measure the distance between Europe and North America with a precision of 3 mm; however due to interference from the Earth's atmosphere, the instrument is precise only to 2-3 cm, and thus cannot depict the 1.7 cm/yr movement predicted by the geological record. The infinitesimal unsteadiness of Earth is another significant source of error. Adjustments for these problems incorporated into analyses of VLBI measurements between Westford, Massachusetts, and Onsala, Sweden, and between Haystack Observatory, Massachusetts, and Onsala, yield a rate of 2.0-+ 0.2 cm/yr. 'A growing consensus that the true error in measurements is ~ 1 cm/yr supports privately held opinions that the detection of continental drift is imminent if not already accomplished.'

In a recent issue of Nature (315:659.), Antoni Hoffman argues that the 26 million year cycle of extinction reported by Raup and Sepkoski (1984) is an artifact of the way the data were gathered, quantified, and analyzed; an editorial in the same issue of Nature seems to agree with him. This author also finds the arguments against periodicity persuasive but concludes it is unlikely that its proponents will abandon the new catastrophism soon. (wbg)

Copper-based antifouling paints were replaced in the 1970s by organotin formulations which are much more toxic to marine life. Though banned 3 years ago in France, Britain has only recently moved to ban the most toxic formulations as of January, 1986, with a review promised for 1987. As the ban applies to its sale, not its use, many boatowners will try to beat the deadline--bad news for the Pacific oyster, Crassostrea gigas, the native British oyster, Ostrea edulis, phytoplankton, barnacle larvae, and filterfeeding bivalves.

Two papers in this issue of Nature (Lorius et al., and Yiou et al.) provide 'an exciting glimpse' of results to come from geochemical study of the 2 km ice core drilled by the Soviets at Vostok Station in Antarctica. The core is the first to span the last interglacial, and appears to provide a continuous record of 'fossil atmosphere' for the last 150,000 yr.

The success of the in-situ geophysical measurements in a borehole through young Pacific crust (Site 504) prompted a return to Hole 418A on the Bermuda Rise to make similar measurements that allow comparison with older and colder crust. Results could indeed be interpreted in terms of crustal aging. In particular, temperature measurements at the Atlantic site suggest conductive rather than convective heat flow implying that porosities of the older crust are sealed off with alteration products, effectively metamorphosing (absenting) Layer 2A.

The catch here is that we don't yet know enough about the effects of increased atmospheric levels of CO 2 and other trace gases (all called the 'greenhouse' gases) to predict the future with confidence, but if we wait until we do it may be too late to affect, prevent, or prepare for it. That current modelling efforts are inadequate does not alarm all scientists; many feel that there is time for another decade of research before decisions must be made. Others contend that this attitude is foolhardy; in the words of one, 'We're performing an experiment on ourselves at a faster rate than we're understanding it.' (slr)

The general kinematics of plate tectonics would suggest that the Arctic Basin is under compression. But recent data indicate that seafloor spreading takes place there too. This is perhaps not so different from the western United States where, in spite of overriding by the East Pacific Rise, active spreading appears to continue. It must be that spreading forces are generated deep in the mantle and can occur despite passive compressional kinematics above. Dept. of Phys., Univ. of Toronto, M5S 1A7, Canada.

The 'longest hard-rock core ever obtained during one leg' was recovered from the Voting Plateau when scientists drilled 1200 m beneath the seafloor through previously reported reflectors and into volcanic rocks of Eocene age that recorded 121 volcanic flows, 49 layers of volcanic debris, and 7 magma dikes. Preliminary findings touched upon here suggest that the plateau region was higher in the Eocene than now; that glassy basalts from below the reflectors contain fragments of continental crust that may be related to the Caledonite Mountains of northern Europe; that the onset of glaciation in the Norwegian Sea began 0.5 myr before a colder climate was present in more southerly North Atlantic waters; and that warm North Atlantic currents entered the Norwegian Sea in the past and were strongest near the coast, similar to present current patterns.

Radon and mercury levels in surface soils may together provide a fairly complete picture of ancient and modern magmatic activity in an area. Because radon is short-lived, elevated levels at the surface reflect recent activity. Mercury, on the other hand, is reactive and cumulative, thus signaling the extent of past activity. Results of Stanley Williams' work in California's Long Valley Caldera are described. (fcs)

Divers trail 'scare lines' with rocks that bounce off coral to herd nearly the entire fish population of a reef into a net, raising the possibility of damaging the reef and exhausting the fish supply.

1982 there it was again on a globe in the Boston Lufthansa office. 'I find myself fighting a wild impulse to ask a Lufthansa agent to arrange a vacation itinerary there via Tokyo.' In fact, there were hundreds of specious islands on the nautical charts of the 1900s--some placed by error in positioning, others by error in documentation; still others were false interpretations (low cloud banks, e.g.), and a few were frauds. Then, of course, the Earth itself has arranged the disappearance of an island or two since its charting. Enjoy some armchair islomania: Spread out the charts inserted in this book, 'gather your favorite atlases and maps around you...translate yourself to that enchanted crimson hour at sea,' and raise the island of your dreams.
