trolled tow system for hydrographic and current measurements with applications. Deep-Sea Res., 26(5A): 579-596.

The remote-controlled fish has variable positive lift and operates on a single conductor wire without fairing or special winch. Examples of its sampling capabilities and the development of secondary bodies that can be towed from the fish are discussed. Lamont- Doherty Geological Observatory, Palisades, N.Y. 10964, U.S.A.

Remote sensing of subsurface water temperature by Raman scattering. Appl. Opt., 18(ll): 1732-1745.

Successful application of the Raman technique for remote sensing of subsurface temperatures in coastal and open ocean waters involves simultaneous measurement of the Raman spectra of the water's monomers and polymers at 2 wavelengths: an equilibrium constant converts the concentration ratio so obtained to temperature. Interferences such as ambient sunlight, fluorescence and surface waves are discussed. Computer Genetics Corporation. Wakefield, Mass. 01880, U.S.A. (izs~

This unconventional, direct method for determining the critical Rayleigh number in B~nard convection has applicability for complicated convection problems where classic analytical techniques fail. Oceano- grafiska Institutionen, G~iteborgs Universitet, Box 4038, 400 40 G~teborg, Sweden. (izs)

Remote sensing of surface ocean circulation with satellite altimetry. Science, 205(4401 ): 1 l - [ 7.

GEOS-3 radar altimetry data for the Sargasso Sea indicate that the average nontidal variability of the oceans is +28 cm. Sea-surface topograph~ measurements from GEOS-3 are in basic agreement with eddy structure determinations by Nimbus-6 infrared imagery.

tion. Acta oceanogr. Taiwan, 8: 98-108.

A tidal current prediction method is based on the relation between the harmonic constants of the tide and tidal current. The linearized momentum equation is applied to derive this model and tidal current harmonic constants can be predicted from a few tidal current data. This method has been verified for the case of Sattahip Bay, Thailand. Department of Oceanography, Taiwan Provincial College of Marine Science and Technology, Keelung, Taiwan, Republic of China.

As part of a program on the Skagerrak to study the large-scale currents at all depths on time scales of a da\ to a year, to investigate North Sea high salinity water mixing with Baltic Sea low salinity water, and to quantify nutrient transport and abundance. hydrographic and chemical data were collected from 23 sections ranging from Hanstholm (Denmark) to Kristiansand (Norway) to Hall6 (Sweden). Primary data are reported in the form of vertical sections. Oceanografiska Institutionen G6teborgs Universitet, Box 4038, 400 40 G6teborg, Sweden. (izs)

A study of historical climatic trends in the vicinity of New Zealand indicates that average water temperatures are declining after a maximum in the early 1970's; possible effects on pelagic fisheries remain in doubt.
