Mechanisms controlling the distribution of Cu, Ni and Cd in surface waters are addressed. Their concentrations in a variety of geographic areas (open ocean, upwelling zones, coastal areas, shelf waters, etc.) are reported. Cu concentrations varied little ocean-wide, but were elevated in the Gulf of Panama and in shelf waters north of the Gulf Stream. Ni and Cd showed distinct regional differences in their element-nutrient correlations. It is suggested that 'residual trace metal concentrations in surface waters can be explained if biological discrimination against trace metals relative to P increases as productivity decreases.'

From 2-50% of the organic solute lost from spiked solutions was found to be adsorbed on the glass container walls. Although this adsorption was reversible it required solvent rinsing to recover most of the solute--a factor which must be considered both when quantitative analyses of trace levels are required and when the analyst wishes to reuse sample containers.

The authors suggest, on the basis of electrochemical data, that the measured redox potential is a steadystate rather than an equilibrium value. Mn equilibrium is calculated from the redox potential; the predominant dissolved ion (Mn +~) is determined. When Mn +2 compound equilibrium concentrations in ocean water are calculated, the ocean is concluded to be Mn-supersaturated. Far East Sci. Center, Acad. of Sci. of the USSR, Vladivostok, USSR. (bwt)

Experiments indicate that ease of degradation of normal alkanes increases with chain length; behavior of gaseous perhalogenated alkanes can be explained by gas exchange alone (no degradation).

Suspended matter in Georges Bank waters was examined during each season and after major storms in both summer and winter. Seston in these waters originates primarily from biological production and resuspension of bottom sediments; suspended matter concentrations on the central shoals are more influenced by storms than by seasonality.

Br to organic C ratios are constant throughout the Gulf of Maine but vary in the estuaries according to the original Br content of the 'various primary productivity sources of sedimentary organic matter.' Some Br enrichment seems to occur during decay of plant material, precluding quantitative use of the ratio; it has value in distinguishing terrigenous from marine sedimentary origin, however.
