4. Distribution of common oceanic (hydrographic) properties (see Chemical Oceanography for basic chemical studies of salinity, chlorinity, etc.) 80:5771 Haney, R. L., 1980. A numerical case study of the d e v e l o p m e n t of l a r g e - s c a l e t h e r m a l anomalies in the central North Pacific Ocean. J. phys. Oceanogr., 10(4): 541-556. A 10-level primitive equation ocean circulation model is used to study the dynamics of large scale temperature anomalies in the open ocean. S i m u l a t e d anomalies are c o m p a r e d with NORPAX data and suggest that anomalous atmospheric forcing is the dominant factor in generating anomalies in the upper 100 m of the North Pacific. Department of Meteorology, Naval Postgraduate School, Monterey, Calif. 93940, U.S.A. (mcs) 80:5772 Kilmatov, T. R. and S. N. Protasov, 1980. Model for calculating thickness of the quasihomogeneous layer of the ocean. (In Russian; English abstract.) Meteorologiya Gidrol., 1980(3): 59-64. The base of the quasi.homogeneous layer (QHL) is assumed to occur at the depth where turbulence is offset by buoyancy; similarity criteria determine mixing within the layer, The approach avoids parameterization difficulties and turbulent energy dissipation in the QHL. Agreement between actual and compvted data is noted. (sir) 80:5773 Polonsky, A. B., 1980. Calculating the characteristics of a quasi-isothermal layer in the equatorial ocean zone.

5. Physical processes (diffusion, turbulence, energy exchange, dynamic heights, etc.) 80:5774 Kowalik, Zygmunt, 1979. Comparison of different methods to e s t i m a t e the e x c h a n g e of m o m e n t u m in the E k m a n layer of the sea. Acta geophys, pol., 27(3): 205-223. Four methods for computing the vertical eddy viscosity coefficient are n u m e r i c a l l y and analytically compared: eddy viscosity as a function

of non-dimensional parameters, constant eddy viscosity based on the empirical wind-surface current velocity relationship, and two statistical methods based on the turbulent energy equations and the scale length and the dissipationfunction. The fourth method yielded very wide-ranging results. Institute of Meteorology and Water Management, Maritime Branch, Gdynia, Poland. (izs) 80:5775 Ling, Beibei, 1980. A study of the laws of smallscale horizontal turbulent diffusion n e a r [mainland] Chinese c o a s t a l a r e a s . (In Chinese; English abstract.) Oceanol. Limnol. sin., 11(1): 1-12. Correlation analysis and a 2-dimensional statistical model are applied to determine the parameters of horizontal turbulent diffusion due to isotropic and small-scale eddies. (izs) 80:5776 Roux, M.

6. Convergences, divergences and upwelling 80:5778 Andrews, W. R. H. and L. Hutchings, 1980. Upwelling in the southern Benguela Current. Prog. Oceanogr., 9(1): 1-81. A hydrographic survey of the southwest tip of Africa reveals that this is the southernmost upwelling site contributing to the Benguela Current. The rate of upwelling is related to the wind and reached a maximum of 32 m/day. Local depletion of dissolved oxygen is seasonably dependent on different factors.
