New techniques in optical and infrared spec- troscopy. (Symposium, 21-22 April 1982.) Phil. Trans. R. Soc., (A)307(1500):465-687; 18 papers.

These proceedings of a two-day meeting devoted to new spectroscopic techniques, especially those em- ploying the tunable laser, open with a survey and critique of laser types. In addition to laser spec- troscopy, papers covered spectroscopic applications of digital electronics, weak radiation flux detection, interferometric methods, and atomic coherence spectroscopy.

Climate Studies. Eos, 64(I):p.2.

The intent of the STACS program (a multi-insti- tutional program of NOAA) is to identify major heat transport processes in the North Atlantic, to develop means to effectively monitor these processes, and to understand North Atlantic circulation dynamics. Initial efforts will focus for a minimum of one year on the Florida Current; several local and remote techniques (electromagnetic induction and coastal tidal measurements, and surface flow radar obser- vations) are being tested for long-term monitoring efficiency.

Three papers treat 0-group eel larvae in terms of their taxonomy, electrophoretic and meristic char- acters, and spatial distribution. Migration and geographic distribution of I- and II-group eel larvae are considered. Also covered are aspects of the eel's environment such as major hydrographic features of the Sargasso Sea, food organisms of pelagic fishes and small invertebrate plankton. (ahm)

disposal: a summary. J. Hydraul. Div., Am. Soc. civ. Engrs, 108(HY!2):1425-1468.

Proper environmental impact analyses of future multiport thermal diffuser installations depend upon adequate prediction of the potential temperature and velocity fields in the receiving water. Thus, the active dispersal processes of the 'near field' and 'inter- mediate field' areas are reviewed, noting the radi- cally divergent nature of the analytical procedures for thermal and conventional sewage diffusers. Three major thermal diffuser designs, their induced circulation pattern characteristics, and predictive techniques are compared. The paper concludes with the examination of some design implications and suggestions for further study. Sch. of Civ. and Environ. Engrg., Cornell Univ., Ithaca, NY, USA. (jch)

Motion characteristics of floating structures. J. Engng Mech. Div., Am. Soc. civ. Engrs, 108(EM6): 1277-1296.

The rigid body response to surface waves of a 2-D floating body is calculated for the case of an enclosed basin. Frequency-dependent added mass coefficients are obtained; then, the equations of motion in the frequency domain are constructed by artificially introducing the damping coefficients. Three forms of damping coefficients are tested against experimental results. Dept. of Architecture, Waseda Univ., Tokyo, Japan. (jfp)
