David Richard Kosiur 1978 160 p Avail: Univ. Microfilms Order No. 7907663 Equilibrium thermodynamic computations were employed in a study of zeolite formation and diagenesis in pelagic sediments. The results of these calculations and observations of diagenetic sequences in deep-sea cores were duplicated by hydrothermal experiments using pelagic sediments and monomineralic natural phillipsite samples. Equilibrium calculations revealed that illite and phillipsite dominate the assemblages, with clinoptilolite becoming more important in more siliceous environments. Hydrothermal experiments indicated that phillipsite is not stable in the presence of silica and transforms to clinoptilolite. Studies of the buffering capacities of various mineral seawater systems suggested that glass-zeolite, clay-zeolite and zeolite-zeolite transformations are important processes controlling the pH of the ocean.

ANALYSIS OF GEOS-3 ALTIMETER DATA AND EXTRACTION OF OCEAN WAVE HEIGHT AND DOMINANT WAVELENGTH Final Report Edward J. Walsh Mar. 1979 30 p refs (NASA-TM-73281) Avail: NTIS HC A03/MF A01 CSCL 08C When the amplitude and timing biases are removed from the GEOS-3 Sample and Hold (S&H) gates, the mean return waveforms can be excellently fitted with a theoretical template which represents the convolution of: (1) the radar point target response; (2) the range noise (jitter) in the altimeter tracking loop; (3) the sea surface height distribution; and (4) the antenna pattern as a function of the range to mean sea level. Several techniques of varying complexity to remove the effect of the tracking loop jitter in computing the wave height are considered. They include: (1) realigning the S&H gates to their actual positions with respect to mean sea level before averaging; (2) using the observed standard deviation on the altitude measurement to remove the integrated effect of the tracking loop jitter, and (3) using a look-up table to correct for the expected value of range noise. Analysis of skewness in the GEOS return waveform demonstrates the potential of a satellite radar altimeter to determine the dominant wavelength of ocean waves. L.S.

Martin (EG and G Analytical Services (NASA-TM-79704) Avail: NTIS HC A03/MF A01 CSCL 08C The mean surfaces of several regions of the world's oceans were estimated using GEOS-3 altimeter data. The northwest Atlantic, the northeast Pacific off the coast of California, the Indian Ocean, the southwest Pacific, and the Phillipine Sea are included. These surfaces have been oriented with respect to a common earth center-of-mass system by constraining the separate solutions to conform to precisely determined laser reference control orbits. The same reference orbits were used for all regions assuring continuity of the separate solutions. Radial accuracies of the control orbits were in the order of one meter. The altimeter measured sea surface height crossover differences were minimized by the adjustment of tilt and bias parameters for each pass with the exception of laser reference control passes. The tilt and bias adjustments removed long wavelength errors which were primarily due to orbit error. Ocean tides were evaluated. The resolution of the estimated sea surfaces varied from 0.25 degrees off the east coast of the United States to about 2 degrees in part of the Indian Ocean near Australia. The rms crossover discrepancy after adjustment varied from 30 cm to 70 cm depending upon geographic location. Comparisons of the altimeter derived mean sea surface in the North Atlantic with the 5 feet x 5 feet GEM-8 detailed gravimetric geoid indicated a relative consistency of better than a meter. M.M.M.

OCEAN TIDAL EXCITATION OF POLAR MOTION (NASA-TM-80243) Avail: NTIS HC A03/MF A01 CSCL 08C : An investigation was conducted to ascertain the response of the rotational motion of the earth to forcing functions produced by the water mass redistribution due to the ocean tides. In particular, the components of displacement of the rotation axis at the surface of the Earth were obtained. The investigation also addressed the larger question concerning the possibility of excitation of the Chandler wobble of the earth. In general, the results show the existence of a polar wobble as a response to each of the components of the ocean tides. The magnitude of the polar displacement depends on two factors: the amplitude of the tidal component and its period. The maximum periodic contributions are: the Doodson's component number 055.565 with a period of 18.613 years and 50 cm of polar displacement, the annual component 056.544 with 37 cm of polar displacement and the semi-annual 057.555 with 32 cm. The tidal components with daily and semi-daily periods yield very small polar displacements of the order of 0.01 cm. The combined effect of all the periodic components can yield as much as 90 cm of pole displacements. The changes produced by the ocean tides in the products of inertia are periodic and regular, therefore, they cannot be the source of excitation of the Chandler wobble. L.S.

The vessels operated at or near the equator in the vicinity of the following longitudes: R/V COLUMBUS ISELIN (U.S.A.) near 28 deg W: R/V ALEXANDER von HUMBOLDT (G.D.R.) near 24 deg W; R/V ACADEMICIAN KURCHATOV (U.S.S.R) near 23 deg 30 min W; and R/V CAPRICORNE (France) near 10 deg W KURCHATOV worked at a fixed position; the other three vessels operated as roving ships. All vessels were equipped with profiling current meters (PCM's), provided by the University of Miami (see Dueing and Johnson, 1972 for details on instrumentation). Current and temperature profiles were taken in the vicinity of anchored radar reference buoys. Profiling operations were routinely carried out to a water depth of 600 meters, lasting about 2-1/2 hours per profile. During the observation of a relative current profile, radar distance and azimuth to a reference broy were observed at 10 minute intervals. A mean drift vector over ground was computed and subsequently used to transform the relative current profile into an absolute profile. The relative error of the measurements made by the ISELIN is approximately + or - 8% of the values of the flow components. GRA N79-23619# Woods Hole Oceanographic Institution, Mass. FREE-DRIFTING BUOY TRAJECTORIES IN THE GULF STREAM SYSTEM (1975-1978) A DATA REPORT P. L. Richardson, J. J. Wheat, and D.

Most of these buoys were launched in cyclonic rings, as part of an interdisciplinary Gulf Stream ring experiment. Other buoys were launched in anticyclonic rings and the Gulf Stream itself. One buoy was launched in a cyclonic Kuroshio ring. The basic data set consists of buoy trajectories and sea surface temperature and velocity measurements along trajectories. The main results consist of a series of buoy trajectories in rings from which the movement of rings is inferred and a series of 20 buoy trajectories in the Gulf Stream. Rings frequently coalesced with the Gulf Stream and some reformed as modified rings. The trajectories of buoys in the stream reveal that at times surface currents are strongly influence by topographic features such as seamounts and ridges. Most buoys in the stream continued to move eastward until they reached the vicinity of the Grand Banks (50 deg W) where they rapidly fanned out, some moving northward, others eastward across the mid-Atlantic Ridge, still others southward and westward.

Lee Butler Feb. 1979 60 p refs A two-dimensional and time-dependent numerical model was developed that calculates the land inundation of a tsunami. The model solves long wave equations that include bottom friction terms. A coordinate transformation was used to allow the model to employ a smoothly varying grid that allows cells to be small in the inundation region and large in the ocean. The model was verified by simulating the 1964 Alaskan tsunami at Crescent City, California. An application of the model to calculate inundation in a region of Hawaii is presented.

The statistical analysis of geochemistry on a great number of manganese nodules samples (collected between the Clarion and Clipperton fracture zones) was used to define the relationships existing among 14 chemical elements. These samples were divided into several groups according to their geochemistry. Each group indicates a different manganese nodule facies, in which the mineralogy of the ferromanganese phase seems to have a particular comportment. The silica and associated elements appear to have an influence on the formation and growth of the manganese nodules. Author (ESA) N79-23622# Centre Oceanologique de Bretagne, Brest (France).

A plan for integrating the various requirements for wildlife monitoring with modern aerospace technology is presented. This plan is responsive to user needs, recognizes legal requirements, and is based on an evolutionary growth from domestic animals and larger animals to smaller, more scarce and remote species. The basis for animal study selection was made from the 1973 Santa Cruz Summer Study on Wildlife Monitoring. As techniques are developed the monitoring and management tasks will be interfaced with and eventually operated by the user agencies. Field efforts, aircraft and satellites, will be supplemented by laboratory investigations. Sixty percent of the effort will be in hardware research and development (satellite technology, microminiaturization) and the rest for gathering and interpreting Author data. O. G. Gazenko and V. V.

Avail: NTIS HC A06/MF A01 The 16-day space flight aboard the orbital station Salyut-3 induced certain immunobiological changes in the cosmonauts. The space flight produced a reduction of the total count of aerobic and anacrobic microorganisms of the upper airways, skin, and the gastrointestinal tract. Postflight the biological properties of the Staphylococcus pathogenic strain remained unchanged. The reduction of the bacterial antigenic impact on the cosmonauts led to a decline of certain parameters of their natural resistance. The space flight brought about a nonspecific stimulating effect of gamma-globulins and increased significantly immunoglobulins. After completion of the mission and return to the Earth environment the content of gamma-globulins (immunoglobulins A, M, G) responsible for immune reactions returned to the normal within a relatively short period of time.

On the 2d postflight day an increased content of aromatic amino acid residues, histidine, and lysine was found in the secretion protiens of the gastric lining epithelium and the cytoplasm of the above glandulocytes, and SH groups were seen in the secretion of the lining epitheliocytes. In the small intestine the content of aromatic amino acid residues increased in the cytoplasm of border enterocytes, and that of SH-groups and free cation proteins decreased in the absorbing border. In the large intestine the cytoplasm and epitheliocyte border showed a decreased content of aromatic amino acid residues, and the border showed a drastically increased content of histidine. Twenty-seven days postflight those changes remained unchanged, increased or decreased. It is suggested that the above changes were caused by the stress effect. J.M.S. Copyright. Avail: NTIS HC A06/MF A01 Human experiments demonstrated that upon repeated vestibular stimulation stability of chromatic vision decreases but spectral and color contrast sensitivity remains unchanged. Preadaptation to the red color reduces the rate with which adysparopy thresholds decline at subsequent vestibular exposures and delays the development of vestibula-vegetative reactions. Positive effect of preadapiation to the green color is minimal. Preadapiation to the blue color increases, upon repeated vestibular stimulation, a decline of adysparepic thresholds to different colors and facilitates motion sickness. The results should be taken into consideration in the selection of color regimens in moving systems. Author Transl. into ENGLISH from Kosm. Biol. Aviakosm. Med. (Moscow), v. 13, no. 2, Mar.

Avail: NTIS HC A06/MF A01 During 49 days a group of test subjects was exposed to head-down tilting, in the course of which they exercised on the bicycle ergometer and were exposed to electrostimulation before and after ergometry. Morphological and histochemical examinations of soleus biopsies showed that bed rest led to a noticeable atrophy of red and white myofibers. The structural changes were accompanied by metabolic alterations, involving a decrease of oxidative metabolism. Electrostimulation done before exercises prevented atrophy and led to hypertrophy of myofibers, which showed, however, the metabolic changes observed after bed rest per se. The combination of exercises and electrostimulation applied after them produced the least pronounced changes in the muscle tissue. The countermeasures against the bed rest induced muscle changes should be developed, taking into consideration both individual characteristics of the muscular system of the test subject and the level of its training.

The phasic pattern of changes of unsaponifiable substances and cholesterol was found. The changes in specific and transport proteins were opposite in most cases. Red blood cell membranes showed a change in their strength and permeability, and a gradual increase in the cholesterol content. If the cholesterol content reached maximum in red blood cell membranes (day 48) it fell down to a minimum in transport proteins. On the contrary, 14 days after completion of the experiment the content of cholesterol in membranes returned to the normal, and in transport proteins increased significantly. By thin-layer chromatography, gas-liquid chromatography, ultraviolet and infrared spectroscopy, it was shown that fast sterols, unsaponifiable esters, and sterol ketoderivatives emerged at an early stage of bed rest. Their content increased at a late stage and did not return to the norm during recovery. Author N79-23637# Joint Publications Research Service, Arlington, Va.

Microfilms Order No. 7909834 The bonding of 02 to hemoglobin (Hb) at the molecular level is discussed. The ideas presented are the results of ab initio calculations on idealized portions of the Hb molecule. The bond between Fe and 02 is formed by coupling a triplet state of Fe to the triplet ground state of 02. The heme plane and axial imidazole ligand were seen to play a key role in promoting reversible 02 binding. The effective how movement of the proximal imidazole, long thought to initiate the change in quaternary structure of Hb, is also responsible for the reduced 02 affinity in the T quaternary form of Hb is shown. The ozone model of transition metal-02 binding leads to the prediction of a second metal-02 stretching band between 1000-1200/cm. It was also used to tentatively assign the near-infrared and z-polarized ultraviolet-visible spectra of Hb02, HbCN, and HbCO. Dissert. Abstr. N79-23647 Carnegie-Mellon Univ., Pittsburgh, Pa.

A total of 832 A-scans (26 blocks) were recorded from 7 normal kidneys, and 896 A-scans (28 blocks) from 7 pyelonephritic kidneys. Dissert. Abstr. N79-23648 Brigham Young Univ., Provo, Utah.
