    In: Detecting structural heat losses with mobile infrared thermography / R.H. Munis, S.J. Marshall and M.A. Bush, Part IV
    Description / Table of Contents: During the winter of 1973-74 a mobile infrared thermography system was used to survey campus buildings at Dartmouth College, Hanover, New Hampshire. Both qualitative and quantitative data are presented regarding heat flow through a small area of a wall of one brick dormitory building before and after installation of aluminum reflectors between radiators and the wall. These data were used to estimate annual cost savings for 22 buildings of similar construction having aluminum reflectors installed behind 1100 radiators. The data were then compared with the actual savings which were calculated from condensate meter data. The discrepancy between estimated and actual annual cost savings is explained in detail along with all assumptions required for these calculations.

    Description / Table of Contents: Current protocols for decontaminating devices used to sample groundwater for organic contaminants are re­viewed. Most of the methods given by regulatory agencies provide little scientific evidence that justify the recommended protocols. In addition, only a few studies that actually compared various decontamination proto­cols could be found in the open literature, and those studies were limited in their scope. Various approaches for decontamination and criteria that are important in determining how effectively a surface could be decontami­nated are discussed.

    Description / Table of Contents: Heat transfer in turbulent flow was measured in a rectangular channel with a width of 0.254 m and a flow depth of 0.0254 m. Correlations between the Nusselt and Reynolds numbers are given for a range of 3020 Re 22360. A Prandtl number range of 9.90 or = Pr or = 12.28 for water was used in the tests. The results are compared with those of other investigations and show that some well-known correlations underpredict the heat transfer by about 35%.

    Description / Table of Contents: Ice cores from Byrd Station and Little America V have been used to test an ultrasonic technique for evaluating crystal anisotropy in the Antarctic Ice Sheet. P-wave velocities measured parallel and perpendicular to the vertical axes of cores from the 2164-m-thick ice sheet at Byrd Station have yielded results in excellent agreement with the observed c-axis fabric profile and with the in-situ P-wave velocity profile measured parallel to the bore hole axis. Velocity differences in excess of 140 m/s for core samples from deeper than 1300 m attest to the strong single pole clustering of crystallographic c-axes about the vertical, especially in the zone from 1300-1800 m. Such oriented structure is compatible only with strong horizontal shearing in this zone. The existence in an ice sheet of widespread shearing several hundred meters above its bed raises serious questions as to the validity of current concepts of the flow of large ice masses that tend to gloss over or ignore crystal alignments of this magnitude.

    Description / Table of Contents: Chemical analysis of surface snows and deeper ice core samples from Milcent, Greenland, indicates a marine origin for Na and Cl and a terrestrial origin for Al, Mn and V. Pre-1900 enrichment factors, based on average crustal composition, are high for Zn and Hg and appear to be related to their volatility. A comparison of pre-1900 and 1971-1973 concentrations of V and Hg shows no decided increase from industrial production; however, the abundance of Zn (relative to Al) increased three-fold during this time period. The chemical composition of ancient ice is extremely useful in interpreting modern aerosols.

    Description / Table of Contents: The primary objective of this investigation was to compile baseline information pertaining to the ocean circulation, especially the extent and patterns of tidal currents and tidal flushing, in Cook Inlet, Alaska, utilizing aircraft and satellite imagery with corroborative ground truth data. LANDSAT-1 and NOAA-2 and -3 imagery provided repetitive, synoptic views of surface currents, water mass migration and sediment distribution during different seasons and tides. Color, color infrared and thermal infrared imagery acquired on 22 July 1972 with the NASA NP-3A aircraft were used to analyze currents, mixing patterns and sediment dispersion in selected areas. Temperature(C), salinity (0/00) and suspended sediment concentration (mg/l) data and hand-held photography were utilized as ground truth information in the interpretation of the aircraft and satellite imagery. Coriolis effect, semidiurnal tides and the Alaska current govern the estuary circulation. Clear, oceanic water enters the inlet on the southeast during flood tide, progresses northward along the east shore with minor lateral mixing, and remains a distinct water mass to the latitude of Kasilof-Ninilchik. South of the forelands, mixing with turbid inlet water becomes extensive. Turbid water moves south primarily along the north shore during ebb tide and a shear zone between the two water masses forms in mid-inlet south of Kalgin Island. Currents adjacent to and north of the forelands are complicated by tidal action, coastal configuration and bottom effects. Turbulence is greatest throughout the water column along the south shore and stratification is more pronounced in Kamishak and Kachemak Bays, especially when fresh water runoff is high.

    Description / Table of Contents: Fourier transforms of selected ground-motion time histories from five underground high-explosive and nuclear detonations are used to define the transmission properties (Transfer functions) of three rock types. Absorption, a measure of a rock's energy dissipating characteristics, is expressed for each of the tests as a function of the frequency of transmission. Dispersion results from a variation in transmission velocity with frequency and is described for each test by a phase velocity spectrum. The transmission properties from one of the sites are used to predict a ground-motion time history at that site from another nuclear event. The potential use of Fourier techniques to make ground-motion predictions and to measure in-situ material properties is discussed.

    Description / Table of Contents: Four large grounded multi-year shear ridge formations were found in the grounded ice subzone of the fast ice zone near the Harrison Bay/Prudhoe Bay area of Alaska. A 166-m-long cross section of one of these formations was obtained by leveling and sonar measurements. These measurements revealed that the maximum ridge height was 12.6 m and that the formation was grounded in 17-18 m of water. The salinity, temperature, brine volume and density of the ice were determined on samples obtained by coring. The physical characteristics of the formations as observed in satellite, SLAR and aerial imagery indicate that these formations have not moved between the time of their formation in the fall of 1974 and August of 1976. Evidence of significant aeolian debris discoloring the ice is discussed.

    Description / Table of Contents: Sections in the Connecticut River where ice jam potential is high were identified through the use of low-altitude black and white photographs taken during low-flow, ice-free conditions. The hydraulics and mechanics of ice jam initiation were investigated in the river reach where these sections were identified. Certain areas were found in the river that had a high susceptibility to ice clogging, but this high potential decreased with increasing discharge because of the improved surface conveyance of the ice through the reach. The stability of ice floes was established along the channel, but the floes generally became unstable as the flow increased. This was calculated by using a Froude number criterion. Grounding locations for ice became evident when the critical Froude number was zero for a given thickness and water depth. No single factor was determined to be responsible for initiating the ice jams in the Connecticut River at Windsor. Apparently there existed a multitude of interacting conditions: surface constrictions, possible high backwater conditions from the Brattleboro Dam, a solid ice cover in the backwater of the Brattleboro Dam that prevented ice transport from the Windsor area, deep pools followed by shallow depth sections upstream of bridge piers, a greater ice thickness accumulation of fragmented floes than would result if a uniform cover could be established in the same reach, and the diurnal fluctuation of river stage casued by the release of water at Wilder Dam.

    Description / Table of Contents: A pavement joint seal prevents the passage of liquids into the pavement base and the intrusion of solids into the joint. The primary mechanical requirements of a pavement seal are that it respond elastically or viscoelastically to any movement of the joint without failure and that it withstand indentation of hard objects like rocks. Because pavement joint movements and seal deformations can be large, elastomeric sealants are often used to form seals. Winter conditions are recognized as the most critical for a seal because of the possibility that failure stresses will be reached as the joint opens to a maximum and the material stiffens in response to the temperature reduction. This report reviews the specific problems and requirements that cold climates create for the performance of elastomeric seals. Emphasis is placed on the material response behavior that can lead to failure of a seal. In an attempt to clarity the mechanics of sealant and seal performance associated with low-temperature pavement applications and to address the issue of low-temperature stiffening That should be a dominant factor in the selection of a sealant, this report presents background information on the formulation and mechanical properties of elastomeric seal materials and the structural behavior of field-molded joint and crack seals.

    Description / Table of Contents: Eight Geoceiver stations were established and suitably marked along or near the crestiline of the Greenland ice sheet during GISP field operations from 1971 to 1975. At one of these stations, DYE-3, repeated Geoceiver positions indicate an ice velocity of 12.7 m.yr on an azimuth of approximately 60 degrees. Data from the International Greenland Glaciological Expedition (EGIG) surveys show that ice flow in the vicinity of Crete is radiating outward from a dome to the south. Two independent calculations of the state of equilibrium at Crete indicate ice sheet thinning rates of 0.25 to 0.37 m/yr, while direct measurement of elevation change by EGIG indicates an ice sheet thickening rate of difference of 0.06 m/yr. Resolution of these differences must await further geophysical work and deep drilling in the ice sheet.

    Description / Table of Contents: Ice fog generated at the Eielson AFB power plant cooling pond contributes heavily to the total ice fog problem on the base. Several methods for ice fog suppression were studied and two techniques were tested experimentally. Experiments were also conducted to determine the magnitude of the various modes of heat transfer within the pond's microclimate. Values of evaporative and radiative heat loss during ice fog are presented. Ice cover is shown to be an effective ice fog suppression technique. Monomolecular films are also shown to be effective and offer some unique advantages, such as ease of application and low overall cost. The heat normally lost to evaporation must be dissipated by other means during suppression. With the ice cover technique this is accomplished by melting the ice cover. During suppression with monomolecular films, the heat must be dissipated by increasing radiative and convective losses. The simplicity of application of monomolecular films, along with their lower cost, combine to make this technique attractive; however, the lower pond temperatures and increased suppression effectiveness weigh heavily in favor of the ice-cover technique.

    Description / Table of Contents: Tests were conducted in uniaxial compression and tension to determine the effect of temperature on the strength of frozen Fairbanks silt. Test temperatures ranged from 0 C to -56.7 C. Two machine speeds, 4.23 cm/sec and 0.0423 cm/sec, were used for the constant displacement rate tests. From the highest to the lowest temperature, the compressive strength increased up to about one order of magnitude and the tensile strength increased one-half an order of magnitude. Equations are presented which correlate strength with temperature at the strain rates obtained. The initial tangent and 50% strength moduli and the specific energy are given for each test. The mode of fracture and the effects of unfrozen water content and ice matrix strengthening are discussed, and the test results are compared with the data of other investigations.

    Description / Table of Contents: It has been reported that small arms projectiles are inherently unstable in snow and that snow has an unexpectedly high ability to stop them and other fast-moving projectiles. Field tests showed that the typical subarctic snow of interior Alaska can be used effectively to provide protection from both rifle and machine gun fire. The undisturbed snow had an average density of 0.18 g/cu. cm., but simple processing, such as shoveling, increased the density to around 0.34 g/cu. cm. Further processing increased the density to above o.40 g/cm3 but densities much above that value were difficult to obtain with simple hand equipment. Tests of the M16 rifle and M60 and M2HB machine guns showed that bullet penetration was inversely related to density - the higher the density the lower the bullet penetration. Design values for the three weapons were determined. A number of types of snow trenches and structures were designed and tested. They were found to provide good protection, in part since bullets showed a strong tendency to ricochet from the snow surface when striking it at a low angle. Burlap bags were filled with snow to revet structures and worked very well. Several types of Russian defensive works of snow were tested but proved unsuitable in the light, weak subarctic snow. The times required for troops to build several types of structures using only shovels and scoops were recorded.

    Description / Table of Contents: Some physical characteristics of two grounded floebergs (fragments of multi-year pressure ridges) near Prudhoe Bay, Alaska, are described. Cross-sectional profiles of the sails and keels of both floebergs were obtained. A sail to keel ratio of 1 to 3.38 obtained with one floeberg was found to be in good agreement with previous investigations. A survey of the sea floor for evidence of scoring induced during grounding yielded a maximum depth of gouging of 1.1m. Additional studies included investigations of the internal structure of the floebergs, and a brief examination of the organic and sedimentary debris found entrained within the floebergs. The grounding of ice on the continental shelves of the Arctic is of considerable interest to those concerned with the development and impact of development of these continental shelves. The field study reported here provides information useful in assessing the nature and characteristics of interactions between floebergs and the sea bed on which they are grounded.

    Description / Table of Contents: Crystalline textures and fabrics of ice cores from the 2164-m-thick ice sheet at Byrd Station, Antarctica, reveal the existence of an anisotropic ice sheet. A gradual but persistent increase in the c-axis preferred orientation of the ice crystals was observed between the surface and 1200m. This progressive growth of an oriented crystal fabric is accompanied by a 20-fold increase in crystal sized between 56 and 600m, followed by virtually no change in crystal size between 6000 and 1200m. A broad vertical clustering of c-axes develops by 1200m. Between 1200 and 1300 m the structure transforms into a fine-grained mosaic of crystals with their basal glide planes now oriented substantially within the horizontal. This highly oriented fine-grained structure, which persists to 1800m, is compatible only with a strong horizontal shear deformation in this part of the ice sheet. Rapid transformation from single- to multiple-maximum fabrics occurs below 1800m. This transformation, accompanied by the growth of very large crystals, is attributed to the overriding effect of relatively high temperatures in the bottom layers of old ice at Byrd Station rather than to a significant decrease in stress. The zone of single-maximum fabrics between 1200 and 1800 m also contains numerous layers of volcanic dust. Fabrics of the very fine-grained ice associated with these dust bands indicate the bands are actively associated with shearing in the ice sheet. Some slipping of ice along the bedrock seems likely at Byrd Station, since the basal ice is at the pressure melting point and liquid water is known to exist at the ice/rock interface.

    Description / Table of Contents: Before vehicle mobility in snow can be reliably predicted, a complete understanding of motion resistance in snow is required. This report examines several aspects of wheeled vehicle motion resistance using results obtained with the CRREL instrumented vehicle. Resistances of leading and trailing tires are examined. Limited data are presented for undercarriage drag, and third and fourth wheel passes in the same rut are initially analyzed, as is how snow deforms around a wheel. For the CRREL instrumented vehicle, a trailing tire has a resistance coefficient of about 0.017 for snow depths less than about 22cm. For deeper snow, the disruption of the snowpack caused by a preceding wheel causes snow to fall into the rut, resulting in higher trailing tire coefficients. For larger vehicles, which in some cases have trailing tires carrying larger loads than preceding tires, the trailing tire coefficients are on the order of 0.048 and 0.025 for second and third trailing wheels respectively. Since there are no trailing tire data available for these larger vehicles, these values are based on nonlinear regression analysis, which includes a prediction of the leading tire resistance. The results and observations of this study are applied in a reanalysis of the towed resistance data obtained during the U.S. Army's Wheels vs. Tracks study. An improved algorithm is presented for predicting wheeled vehicle motion resistance caused by snow.

    Description / Table of Contents: In der belebten Natur wie in Böden und Wässern gefundene Kohlenwasserstoffe müssen nicht notwendigerweise von Mineralölen herrühren. Kohlenwasserstoffe verschiedenen Aufbaus sind vielmehr ubiquitärer Bestandteil der Bio-, Hydro- und Geosphäre. Bei der Planung sinnvoller Sanierungsmaßnahmen bei Ölunfällen sollte diesem Umstand Rechnung getragen werden. Dieser Leitfaden gibt dem Untersuchenden Kriterien an die Hand, nach denen er in vielen Fällen zwischen biogenen und mineralölbürtigen Kohlenwasserstoffen differenzieren kann wie auch eine Reihe erprobter analytischer Methoden, das Vorliegen solcher Kriterien nachzuweisen.
    Description / Table of Contents: Hydrocarbons occuring in the living nature as well as in oil and water do not necessarily originate from mineral oil. Hydrocarbons of various structures are ubiquous components of the biological, hydrological and geological environment. When planning meaningfull clean-up measures in case oil spillages this fact should be duly taken into account. This manual offers criteria by means of which in many cases the investigator will be able to differentiate between biogenic hydrocarbons and such deriving from mineral oil. Furthermore it describes some proven analytical methods to ascertain the presence of said criteria.

    Description / Table of Contents: An analytical study of the propagation of shock waves in snow was carried out to evaluate the response of medium density snow to high rates of loading. One solution was developed for steady shock waves; this resulted in calculation of pressure jump, density jump and stress wave speed. Correlation with available experimental data was found to be good. Nonsteady shock waves were also considered in order to evaluate wave attenuation rates in snow. Very few data were available to compare with the analytical results, so no definite conclusions on the part of the study could be made. The results show, however, that shock waves that produce plastic deformation attenuate at extremely high rates and that differences in pressure between two waves are quickly eliminated within a short distance. Calculations were also made to evaluate the effect of wave frequency on attenuation rates. The results show that, for plastic waves, frequency is not a predominant factor for determining attenuation rates.

    Description / Table of Contents: Transmission and scanning electron micrographs of Umiat bentonite revealed thin, mica-like grains with irregular shapes. Most of the bentonite showed electron diffraction ring patterns, but some showed hexagonal net patterns as well as ring patterns. The lengths of the unit cells were calculated to be 5.18 A along the a-axis and 8.97 A along the b-axis. Semiquantitative analyses were made using an energy dispersive spectrometer. Common elements such as Si, Ti, Al, Fe, Mg, Na and K were determined. The molecular ratio of SiO2:Al2O3 was calculated to be 492:100 for the bulk sample, indicating that Umiat bentonite is similar in most respects to Wyoming bentonite, and is classified as a mont-morillonite. The microstructure of frozen Umiat bentonite was observed at a specimen temperature of -100 C using a scanning electron microscope equipped with a cold stage. Frozen bentonite and segregated ice patterns formed from wet bentonite were examined using an X-ray map and Si X-ray line scan. Sublimation processes of ice in the frozen bentonite were observed at specimen temperatures of -60 and -80 C. After sublimation of the ice the bentonite displayed a honeycomb structure. It was concluded that the freezing-sublimation cycle in frozen soil increases the permeability of water vapor due to the three-dimensional structure of the coagulated clay formed by freezing.

    Description / Table of Contents: The motion of dislocations in single crystal ice under an electric field was observed by using X-ray topographic methods. Electric charge density on these dislocations was deduced from the amplitude and length of the dislocation segment under the known AC electrical field. The most likely linear charge density was about +5x10^-11 c/m, although considerable variation is possible depending on the effective field acting on the dislocation lines.

    Description / Table of Contents: The performance of surface impedance and magnetic induction electromagnetic subsurface exploration techniques was studied seasonally at various sites in Alaska where permafrost and massive ground ice occurred. The surface impedance method, which uses radiowaves in the LF and VLF bands, and the magnetic induction method, which uses low-frequency magnetic induction fields, distinguish subsurface materials by the electrical resistivity of the materials. The methods used have greatest sensitivity within about 20 m of the surface and are, therefore, most applicable for shallow subsurface investigations. The selection of study sites was based on anticipated contrasts in electrical resistivity between ground ice and adjacent earth materials. A magnetic induction instrument, using a separation of 3.66-m between the transmitter and receiver antennas, in general was able to detect near-surface zones of massive ice and to provide data regarding permafrost distribution in both the Fairbanks and Prudhoe Bay areas. At this antenna separation, the depth of magnetic field penetration was sufficient to include mainly the zone containing maximum contrasts in resistivity between ground ice and other earth materials. In the Fairbanks area, contrasts, in this zone were greatest in late winter when the seasonally thawed surface layer was completely frozen. When thawed, this layer usually becomes more conductive and often masks the deeper resistivity contrasts. In the Prudhoe Bay area, maximum ground resistivity contrasts were detected in late summer when shallow subsurface temperatures had risen sufficiently to permit resistivity contrasts between the massive ice and the ice-rich ground to appear.

    Description / Table of Contents: Die Dobsonmessungen der Stadt Potsdam und der Ozonsondenmessungen von Lindenberg werden homogenisiert und klimatologisch ausgewertet. Zur Homogenisierung der Dobsonmessungen werden dabei neben den allgemein üblichen Verfahren Regressionsbeziehungen mit aerologischen Temperaturwerten als Prediktoren verwendet, die sowohl als Qualitätstest für die Dobsonmessung als auch als Prognosegleichung zur Vorhersage des Gesamtozongehalts verwendet werden können und wurden. Es wird gezeigt, daß sowohl die Verteilungsmuster des Gesamtozongehalts als auch die der langzeitigen Ozonänderungen wetterlagenabhängig sind, wenn zur Wetterlagenklassifikation ein objektives Klassifikationsschema mittels Clusteranalyse auf der Basis des Bodendruckfeldes und des Höhendruckfeldes der 500 hPa-Fläche verwendet wird. Diskutiert werden die Beziehungen zwischen objektiv klassifizierten Wetterlagen und den weit verbreiteten Wetterlagen nach Hess-Brezowsky. Für alle Wetterlagen wird für das Untersuchungsgebiet i.a. Ozonabnahme für alle Jahreszeiten gefunden. Änderungen in der atmosphärischen Zirkulation modifizieren damit auch die Stärke der Ozonabnahme, können aber eine Umkehr des Trends nicht bewirken.

    Description / Table of Contents: Some Bessel function identities found by solving problems of the deflection of a floating ice plate by two different methods are rigorously proved. The master formulas from which all the identities are derived are in a Fourier reciprocal relationship, connecting a Hankel function to an exponential function. Many new formulas can be derived from the master formulas. The analytical method presented here now opens the way to study a hitherto impossible type of problem--the deflection of floating elastic plates of various shapes and boundary conditions.

    Description / Table of Contents: A 19-year record of the annual closing and opening dates of operation of the Lake Champlain ferry at Grand Isle, Vermont, which are controlled by the lake's ice cover, was made available to CRREL. These navigation records accurately approximated the freeze-over and breakup dates for the ferry crossing area between Gordon Landing, Vermont, and Cumberland Head, New York. When compared statistically with water temperature and climatological data for the same years at nearby Lake Champlain locations, the dates allowed accurate predictions of ice formation. From nearby air temperature records, cumulative freezing degree-day (deg C) curves were plotted for each year of record, and ice formation dates and standard deviations were predicted with considerable accuracy. Several methods of predicting ice formation on Lake Champlain were attempted. The most accurate approach used a combination of water temperatures and freezing degree-days. The influence of wind speed on ice cover formation and prediction are also discussed in the report.

    Description / Table of Contents: Zusammenfassung Die pliozänen Sedimentprofile der ODP-Bohrungen 925-929 bilden einen Tiefenwasserabschnitt im äquatorialen Westatlantik zwischen 3000 und 4400 m Wassertiefe und wurden für die Zeitscheiben 3.3-2.6 Ma und 5.1-4.4 Ma untersucht. Anhand von zeitlich hochauflösenden isotopisch-sedimentalogischen Datensätzen wurden die Zusammenhänge zwischen Änderungen im polaren Eishaushalt, ozeanischer Zirkulation, Tiefenwasserdurchlüftung, Karbonatlösung und terrigenem Sedimenteintrag vom Amazonas näher rekonstruiert. Dafür wurden die Zeitreihen an die astronomische Zeitskala von Laskar et al. ( 1993) angepaßt. Die vorliegende Studie belegt erstmals, daß die Schließung des Panama-Seeweges vor 4.6 Ma einen kritischen Grenzwert überschritt, der nachweislich zu einschneidenden Veränderungen in der thermohalinen Zirkulation und der Tiefenwasserchemie führte. Das frühe Pliozän vor 5-4.6 Ma zeichnete sich durch eine extreme Karbonatlösung und eine geringe Tiefenwasserdurchlüftung aus. Im Zuge der Schließung führte die Intensivierung des Golfstromes mit einem erhöhten Salz- und Wärmetransport in den Nordatlantik und die Anregung der dortigen Tiefenwasserbildung zu einer verstärkten thermohalinen Zirkulation und letztendlich zu einer verbesserten Tiefenwasserdurchlüftung und Karbonaterhaltung im äquatorialen Atlantik. Damit verbunden war eine Absenkung der Lysokline bis zu 1000 m. Ein pazifisch-atlantischer Vergleich von Karbonatlösungsindikatoren zeigt, daß sich die chemische Asymmetrie zwischen beiden Ozeanen, wie sie auch heute noch besteht, bereits ab 4.6 Ma entwickelte. Zeitgleich mit der Verflachung des mittelamerikanischen Seeweges vor 4.6 Ma weist ein deutlicher Anstieg in den siliziklastischen Akkumulationsraten gemeinsam mit Ergebnissen aus terrestrisch-lakustrinen Poilenprofilen auf die verstärkte Hebung der Anden hin. Mit der Intensivierung der Nordhemisphärenvereisung vor 3.15-2.6 Ma wurden die Schwankungen in den Sauerstoffisotopenkurven oberhalb 3300 m Wassertiefe (NADW = Nordatlantisches Tiefenwasser) von einem 100 ka-Zyklus dominiert, während sie darunter von dem für das Pliozän typischen 41 ka-Zyklus der Erdschiefe dominiert wurden. Möglicherweise ist das Auftreten des 100 ka-Zyklus ein typisches Phänomen für Zeitintervalle, die mit einem verstärkten Eisaufbau einhergehen, wie z. B. das Pleistozän der letzten 800 ka. Im Zuge der Vereisung nahm die Bildung von NADW ab und führte im äquatorialen Atlantik zu einer graduellen Abnahme in der Tiefenwasserdurchlüftung und Karbonaterhaltung. Während die Lysoklinentiefe in den Warmstadien in etwa der heutigen Lage entsprach ( ca. 4300 m Wassertiefe ), verlagerte sich die glaziale Lysokline in flachere Wassertiefen um etwa 3500 m. Die Schwankungen in der Lysoklinentiefe (Grenzfläche NADW/AABW) wurden dabei vom 41 ka-Zyklus dominiert, wobei die Lösungsmaximaden Maxima im Eisvolumen mit zunehmender Wassertiefe vorauseilten. Im Bereich des NADW schwankten Karbonatlösung und Eisvolumen in Phase und dokumentieren den bekannten atlantischen Karbonaterhaltungstyp. In einer Wassertiefe unterhalb 4000 m, also im Bereich der Mischzone NADW/AABW oder im AABW (=Antarktisches Bodenwasser), eilten die Karbonatlösungsmaxima den Maxima im Eisvolumen bis zu 5000 Jahren voraus, ein Phasenunterschied, der typisch für südatlantische Wassermassen ist. Die pliozäne terrigene Sedimentanlieferung von Amazonasfracht zur Ceara Schwelle wurde nach spektralanalytischen Ergebnissen nicht durch Meeresspiegelschwankungen oder kontinentale Klimaänderungen (Niederschläge, Vegetation) kontrolliert, sondern vielmehr durch strömungsbedingte Transportprozesse im Zusammenhang mit dem nordbrasilianischen Küstenstrom.

    Description / Table of Contents: Das Buch bietet eine Einführung in die moderne Klimatologie mit ihren Prognose- und Interpretationsmodellen. Es gibt einen Überblick über die Vorstellungen, die man heute vom Klima und von klimarelevanten Prozessen hat, und wie man diese konzeptionell und quantitativ - also mit Modellen - zu beschreiben versucht. Der Text ist allgemein verständlich geschrieben und setzt keine besonderen Kenntnisse der Mathematik und Physik voraus. Dieses Lehrbuch basiert auf einer Vorlesung am Meteorologischen Institut der Universität Hamburg und richtet sich hauptsächlich an Studenten der Geowissenschaften und Physik, daneben an ebenfalls mit Klima befaßten Disziplinen der Land-, Forst- und Umweltwissenschaften

    Description / Table of Contents: Zusammenfassung Im südlichen Südatlantik wurden umfassende Untersuchungen zum Bariumkreislauf durchgeführt. Sie dienen zum besseren Verständnis des Barium/Barytsignals als Produktivitäts- 'bzw. Paläoproduktivitätsanzeiger in antarktischen Sedimenten und sollen Rückschlüsse auf die Paläozeanographie im Antarktischen Zirkumpolarstrom zulassen. Dazu wurden Untersuchungen an der Wassersäule, an Sinkstofffallenmaterial, am Oberflächensediment, Porenwasser und an langen Sedimentkernen durchgeführt. Untersuchungen zum gelösten Barium im Meerwasser auf zwei Profilen im westlichen Südatlantik zeigen, daß die Bariumkonzentrationen innerhalb des Antarktischen Zirkumpolarstromes im Vergleich zu anderen Ozeanen relativ hoch sind. Die verschiedenen Wassermassen werden von den Bariumgehalten nachgezeichnet, so daß an den ozeanegraphischen Fronten ähnlich wie bei anderen ozeanegraphischen Parametern ausgeprägte Gradienten auftreten. Die vertikale Verteilung gelösten Bariums innerhalb der Wassersäule korreliert mit der Verteilung gelösten Silikates, was auf eine Kopplung von Barium an den biogenen Stoffkreislauf schließen läßt. Das gelöste Barium wird von den Hartteilen absinkender Silikatschaler aufgenommen und in der unteren Wassersäule und im Sediment wieder freigesetzt. Die Barytsedimentation ist nicht abhängig vom Gehalt gelösten Bariums innerhalb der Wassersäule. Vielmehr ist das Auftreten von Diatomeen und eine hohe Exportproduktion bei der Bildung von Baryt entscheidend. Die Barytbildung scheint an den Abbau organischen Materials innerhalb der Wassersäule gekoppelt zu sein, da das Corg/Babio-Verhältnis in den Sinkstofffallen mit zunehmender Wassertiefe abnimmt. Die Zunahme biogenen Bariums mit der Wassertiefe, die sowohl in den Sinkstofffallen als auch in Oberflächensedimenten beobachtet wurde, verdeutlicht die große Stabilität von Barium in Form von Baryt im Vergleich zu organischem Kohlenstoff, Opal und Karbonat. Im Antarktischen Zirkumpolarstrom wird innerhalb der Antarktischen Zone mengenmäßig das meiste biogene Barium akkumuliert. Dieser Bereich ist ebenfalls durch eine hohe Opalakkumulation gekennzeichnet, die ihren Ausdruck in der Ausbildung des Opalgürtels um die Antarktis findet. Diese Übereinstimmung läßt daher eine Anwendung von Barium als Produktivitätsanzeiger möglich erscheinen. Die Primärproduktivitäten, welche mit Hilfe des Flusses von biogenem Barium bestimmt wurden, bewegen sich in der Antarktischen Zone um ca. 40 gC/m2/a und sind somit deutlich niedriger als z.B. in Küstenauftriebsgebieten. Im Wechsel von Warm- und Kaltzeiten lassen sich signifikante Änderungen der Bariumkonzentrationen feststellen. Eine diagenetische Überprägung des Bariumsignals durch Barytmobilisation und anschließender Wiederausfällung kann in den untersuchten Sedimentkernen ausgeschlossen werden. Die in den Oberflächenproben beobachtete Korrelation zwischen den Akkumulationen biogenen Bariums und biogenen Opals ist ebenfalls in den Kernprofilen nachvollziehbar, wodurch die Anwendung biogenen Bariums als Proxy für Paläoproduktivitäten in antarktischen Sedimenten möglich wird. Innerhalb der Antarktischen Zone werden während der Interglazialzeiten die höchsten Akkumulationsraten von biogenem Barium beobachtet, mit maximalen Werten während der Klimaoptima im Holozän und vor ca. 125.000 Jahren. Während der Warmzeiten war daher die Hochproduktionszone in der Antarktischen Zone ausgebildet. Dagegen kommt in den Kaltzeiten nördlich der Polarfront mehr biogenes Barium zur Akkumulation. Eine nordwärtige Verschiebung der Polarfront und damit des Hochproduktionsgürtels während der Glazialzeiten kann aber ausgeschlossen werden, da die Akkumulationsraten von biogenem Barium viel niedriger sind als die warmzeitliehen Raten innerhalb der Antarktischen Zone.
