Spectral analysis of data from 3 equatorial stations reveals the intensity and zonal propagation of equatorial waves in the lower stratosphere. Two kinds of wave disturbance are identified: eastward propagating 10-20 day disturbances of the zonal wind component, and westward propagating 4-5 day disturbances of the meridional wind component. The 4-year averaged spectra and biennial and annual cycles are discussed. Meteorological Research Institute, Suginami, Tokyo 166, Japan. (rlo)

A synoptic classification of summer atmospheric circulation accounts for observed variations in the energy and mass balance climates of Meighen Ice Cap. Three synoptic types are defined which are related to variations in surface conditions, solar angle, and precipitation form; the types are represented by the position of the 500-mb Low influencing Meighen Island thus providing a link between mass balance conditions and the general circulation.

Fractionation of whole water samples through 22gm mesh screens reduced the concentration of particles with mean spherical diameters (MSD) >10 urn. Fractionation did not affect particle concentrations <10 gm when nanoplankton dominated but resulted in an increase when net plankton dominated as a consequence of the breakup of chains. A 50% removal usually occurred at a MSD of 16 gm. Correlations between the chlorophyll a content and volume of size fractions were significant, and nanoplankton had more chlorophyll a per unit volume than net plankton.

In view of the recent recognition of the importance of abandoned larvacean houses (fragile filterfeeding structures secreted by urochordates that retain the larval tunicate 'tadpole' anatomy) as a substrate for microorganisms and as a source of organic aggregates, several types of giant (30-100 cm) larvacean houses are discussed based on observations made over 10 years ago during deep submersible dives along the western Central American coast.

Population structures of CapreUa laeviuscula Mayer and Deutella californica Mayer are compared and factors structuring the populations are discussed. The number of D. californica per instar continuously decreased after emergence from the brood pouch. Populations of C. laeviuscula had (1) an initial decrease in numbers; (2) an increase in cohort size at middle instars; and (3) decreasing population size. For both species population declines were caused by molting-related deaths. Population structures of C. laeviuscula were also caused by selective predation, intraspecific conflict during amplexus, and by rapidly molting juveniles becoming slow molting as adults.

Ingestion rate of a selective deposit feeder in a complex mixture of particles: testing the e n e r g y - o p t i m i z a t i o n hypothesis. Limnol. Oceanogr., 24(5): 867874. A simple hyperbolic model describes the relationship between the rate at which Corophium volutator (Crustacea: Amphipoda) ingests sediment and the particle-size spectrum in the sediment. Mixtures of natural sedimentary floc and glass spheres were used in the feeding experiments. Ingestion rate depends not only on the concentration of edible material but also on its composition as measured by the ratio of sphere volume:floc volume. The parameters of the model are therefore

By means of potentiometric titrations, the coppercomplexing properties of organic compounds released by 21 algal species are characterized. Most eucaryotic species released measurable amounts (10 6 M) of copper-complexing agents that could be modeled as weak organic acids. Of seven bluegreen algal species studied, four produced about 5 x 10 7 M concentrations of strong coppercomplexing agents with conditional stability constants in the range 10~ to 10~ ; two produced complexing agents similar to those produced by the eucaryotes.

Most planktonic Foraminifera (spinose and nonspinose) are omnivorous, feeding primarily on diatoms and dinoflagellates. The carnivorous Hastigerina pelagica is an exception. The diversity of prey accepted, the ability to survive without food for days, and a moderate predation pressure may help to explain foraminiferal abundance and geographical diversity.

In 36 Arctic tundra ponds near Barrow, Alaska, there were 21 examples of a large species association, 9 of a small association, and 6 intermediate associations. Statistically, the species show evidence ef nonrandom association. Intermediates are found to occur, and in some cases make up a high proportion of the observed cases. Distinct associations are the result of a constellation of the proper chemical, physical, and biological factors and, for that reason, distinct associations are expected to be uncommon.

Bacterial denitrification is shown to result in the accumulation of nitrites and associated decrease of nitrates. According to the denitrification equation, at intermediate depths an increase of ammonium nitrogen may be expected; its absence is attributed to accumulation by nitrobacteria as nitrates are reduced.

This discussion was held in collaboration with the Marine Pollution Subcommittee of the British National Committee on Oceanic Research, and considered (but not exclusively) topics such as: the need for sublethal studies, physico-chemical limitations in e x p e r i m e n t a l investigations, experiments with enclosed ecosystems, uses of experimental ecosystems, pollution-induced population changes, separation of natural from pollution-induced changes, and practical application of experiments and field trials to pollution control.

The impact of density independent mortality, such as that induced by pollution, generally shifts a fish population from K-strategy (self-stabilizing) to rstrategy (opportunism) and implies a decrease in density dependent mortality with a corresponding poor recovery in low stock populations. The impact upon high stock populations generates increased stock of decreased resilience with unknown consequences.

The earliest and most significant change caused by pollution in a community may be the departure from a log-normal distribution of individuals among species. The dominant species in a polluted area may be those which have a flexible life history rather than those able to tolerate adverse conditions.

A positive correlation between the concentrations of selenium and mercury was observed, although in-vitro studies with seal liver homogenates gave no insight into the role of selenium in the demethylation process.

Insidious, subtle and oftentimes inducing no overt s y m p t o m s of distress, sublethal effects of pollutants can exact their toll on marine fish stocks causing declines and eventual disappearance, Types of sublethal effects, bioassays, controlled ecosystem experiments, extrapolation of real-world data from laboratory results, pollution control, establishing 'safe' concentrations of toxicants, and distinguishing fluctuations in fisheries caused by natural environmental factors from those caused by pollutants are all discussed in the context of maintaining healthy marine fish stocks.

Toxicol., 23(1/2): 281-284. Parathion applied to cotton fields near Corpus Christi, Texas, in June 1978 was responsible for extensive mortality among adults and immature Larus atriciUa. This is probably the first recorded instance of an organophosphate insecticide killing due to insects carried to the young by adults.

However, total Cd content did decrease as soft tissue weights decreased during the experimental period. Environmental Research Laboratory, South Ferry Road, Narragansett, R.I. 02882, U.S.A. (mjj)

Certain conditions imply the existence of policies that 'minimize risk' of undesirable events for stochastic harvesting models. For many problems, either such a policy will not exist, or else it is an 'extreme' policy that is equally undesirable. Techniques are given to systematically trade off decreases in the long-run expected return with decreases in the long-run risk.

Results of organic manuring experiments indicate that primary productivity is not sufficient to account for the high fish yields attained in manured systems. It is suggested that manuring may function both as a fertilizer and as a fish growth promoter through some as yet undefined pathway. Apdo. Postal 94-28, Mexico 10, D.F., Mexico. (izs)

It was concluded that food, through its contribution of nutrient salts and bacteria, had a major influence on larval culture. The physico-chemical characteristics of seawater were not modified by heat or filtration t r e a t m e n t s , nor b a c t e r i a eliminated. In effect the larvae were raised in an artificial environment subject to marked fluctuations which had mechanical and biological origins.

Appl. Ocean Res., 1(3): 147-157. Linear shallow water theory, verified by numerical methods for arbitrary wavelength, is used to test the efficiency, wave forces, raft movements, optimum design and cost effectiveness of raft trains which generate energy through wave-induced rotation about hinges. Two or three rafts are found to be adequate; this device is compared with Salter's cam.

(a translation of Akust. Zh.), 25(2): 162-163. This acoustical technique for determining course speed and lateral drift of a vessel is based upon 'simultaneous measurement of the autocorrelation and cross-correlation coefficients of fluctuations of the envelopes of bottom-reflected sound signals.' Major advantage of the method lies in its ability to measure small ship speeds relative to the bottom. Acoustics Institute, Academy of Sciences of the U.S.S.R. (izs)
