compressa Dana and Fungia scutaria Lamarck were measured under controlled temperatures. Results indicate that coral metabolism is closely adapted to ambient temperature conditions. Tropical corals measured at Enewetak, Marshall Islands, showed greater primary production compared to maintenance requirements at elevated temperatures than did subtropical varieties of the same species in Hawaii. Photosynthesis:respiration (P:R) ratios were significantly and negatively related with temperature between 18/sup 0/ and 31/sup 0/C for all Hawaiian corals, whereas at Enewetak this ratio generally showed a curvilinear relationship for this temperature range. ‘ Extrapolations of P:R regressions on temperatures to a value of 2.0 (estimated as a minimum required for long-term functional autotrophy) coincide for Hawaiian specimens with published upper lethal temperatures. Extrapolation of P:R regressions for Enewetak specimens at temperatures above 25/sup 0/C suggests lethal temperatures for these corals to be 2 to 5 C/sup 0O/ higher than for Hawaiian corals, in good agreement with recent experimental findings. Interspecific differences in P:R temperature regressions for Hawaiian corals corelating with upper lethal temperature tolerances are described.; Major Descriptors: *CORALS -- TEMPERATURE EFFECTS Descriptors: AMBIENT TEMPERATURE; ENIWETOK; HAWAII; MARSHALL ISLANDS; METABOLISM; MORTALITY; PHOTOSYNTHESIS; PRODUCTIVITY; RESPIRATION Broader Terms: ANIMALS; CHEMICAL REACTIONS; CNIDARIA; INVERTEBRATES; ISLANDS; MARSHALL ISLANDS; NORTH AMERICA; PHOTOCHEMICAL REACTIONS; SYNTHESIS; USA; WESTERN REGION Subject Categories: 560204* -- Thermal Effects ~- Invertebrates -- (-1987) 10/5/955 (Item 655 from file: 103) 00381228 ERA-03-037941; EDB-78-075631 Title: Solar occultation measurements of the water vapor mixing ratio in the stratosphere and mesosphere from the Salyut-4 orbital station Author(s): Kondratev, K.Ya.; Buznikov, A.A.; Grechko, G.M.; Gubarev, A.A.; Pokrovsky, A.G.

The solar occultation measurements were performed at sunrise. An IR spectrometer with the channel range of 3800 to 3825 cm/sup -1/ and spectral resolution of 0.8-© em/sup -1/ was used. The results obtained revealed the presence of a ‘'dary’’ stratosphere with the mixing ratio of about 10/sup -6/ over Marshall Islands at the time of the experiment.; Major Descriptors: *MESOSPHERE -- WATER VAPOR; *STRATOSPHERE -- WATER VAPOR@ ; *WATER VAPOR -- MONITORING Descriptors: MARSHALL ISLANDS; MIXING; SPECTROMETERS; SUN Broader Terms: EARTH ATMOSPHERE; FLUIDS; GASES; ISLANDS; MEASURING INSTRUMENTS; STARS; VAPORS Subject Categories: -~- (-1989) 10/5/956 500100* -- Environment, Atmospheric -- Basic Studies (Item 656 from file: 103)
