on the west coast of South Africa and some eco- logical implications. Botanica mar., 22(4): 237-240.

Fatty acid patterns, lipid content (0.4%-0.7% fresh weight) and lipid classes were determined in Laminaria pallida, Ecklonia maxima and Macrocystis angustifolia. Contribution of the laminarians to surface slicks and sea foams was assessed by comparing fatty acid patterns in kelps, slicks and foams.

isotope effects in the assimilation of inorganic nitrogenous compounds by marine diatoms. Geo- microbiol. J., 1(15: 85-101.

The isotopic composition (6~SN) of Phaeodactylum tricornutum and Chaetoceros sp. ranged from 7 to --18°/oo. Fractionation ranged from negligible at growth rates higher than l day - 1, to 1.016 at a growth rate of 0.025 day -~. The N isotope fractionation primarily takes place at the step of N-O bond breaking in nitrate reduction to nitrite. Mitsubishi-

Short-term variability in surface catches of ichthyoplankton in the upper Chesapeake Bay. Estuar. coast, mar. Sci., 8(6): 511-522.

Knowledge of short-term (i.e., hourly) distribution and abundance of ichthyoplankton as affected by biological and water transport factors is essential to design a sampling scheme capable of accurate estimates of mean numbers and true differences in distribution over larger time periods between different locations. The results of this study are discussed in terms of the confidence which can be assigned to the differences noted. Chesapeake Bay Institute, The Johns Hopkins University, Baltimore, Md. 21218, U.S.A.
