    Description: The Murray fracture has been thought to extend ashore into the Transverse Ranges of California, but a geophysical study shows no evidence of structural continuity between these features. Instead, basement morphology typical of the Murray fracture zone ends where its known magnetic and bathymetric expression dies out. Similarly, east-west Transverse Range structures change direction so that they are parallel to the northwest trend of the coast rather than crossing the continental shelf and slope. The lack of continuity suggests an independent development of the Transverse Ranges since at least mid-Tertiary time along an older structural trend continuous with the Murray fracture zone. Possibly a fundamental lineament in the crust, an extension of the Murray, inactive since at least the mid-Tertiary, provided a convenient trend for development of the Transverse Ranges in response to deformation along the San Andreas fault system. The Murray fracture zone is thought by some authors to be a transform-fault. The transform-fault hypothesis alleviates some difficulties that arise in explaining the origin of the zone by transcurrent faulting but equivalent uncertainties seem to accompany the newer explanation.

    Description: Sedimentary iron and heavy-metal deposits of undetermined size have been found in the middle of the Red Sea some 2000 meters below the surface of the sea (Fig. 1). This discovery has been made from the Research Vessel Atlantis II, which is still at sea engaged in a series of oceanographic investigations which ultimately will end in November 1965, after the ship has circumnavigated the globe. The discovery is significant because the environment and the processes controlling deposition of heavy metals are observable and appear to be still active.

    Description: This paper summarizes the hydrogeology of the thick carbonate-evaporite sequence that extends from land surface to the oil horizons at depths of about 11,500 feet below sea level in southern Florida. It sets forth the few known facts about the hydrology of the deep water-bearing rocks and discusses a hypothesis concerning the cyclic flow of salt water related to geothermal heating in the Floridan aquifer. Meinzer (1923, p. 30) defined an aquifer as a "formation, a group of formations, or part of a formation that is water bearing." The connotation of quantity was included by the statement: "Few if any formations are entirely devoid of gravity ground water, but those that do not contain enough to be of consequence as a source of supply are not rated as water bearing." The quality of the water does not enter the definition, for if it did, a change in quality (as by salt-water encroachment) would correspondingly convert aquifers to nonaquifers. This paper treats permeable water-bearing beds as aquifers even though the contained water might be a brine seven times as salty as sea water and, therefore, normally not considered a source of supply.

    Description: Calcium absorbtion was measured in fasting human beings after oral administration of Ca^45 in a solution containing 10 to 500mg stable calcium and an intravenous dose of Ca^47. Absorbtion was determined from the ratio of specific activities of the two isotopes (oral dose/intravenous dose) in calcium of urine collected more than 24 hours later. The accuracy of this calculation was confirmed by comparison with absorbtion calculated from recovery of the oral dose in stools (the completeness of collection being determined from recovery of simultaneously given Cr2O2or Cr^51 labeled protein and a correction for endogenous calcium being made from the fecal recovery of the intravenouse dose of Ca^47). In 20 tests, the average difference between the two calculations of per cent absorbtion was 2.2 and the coefficient of variation, 1.6. The Conditions under which the double isotope procedure gives an accurate result were evaluated and the results of its use with 3 different doses of calcium given to normal subjects are reported

    Description: Miesmuscheln gleicher Anfangslänge vom Kieler Olympiahafen wurden 1961 in der Kieler Förde und im Nord-Ostsee-Kanal ausgesetzt und Untersuchungen über ihr Wachstum und dessen Abhängigkeit vom Nahrungsangebot und anderen Umweltfaktoren durchgeführt. Die Aufnahme und Verdauung der Nahrung, die Bedeutung von Nahrungsfaktoren für das Wachstum und die Beziehung zwischen abfiltrierter organischer Substanz und Zunahme der Weichteilgewichte wird diskutiert. Unter gleichen Aktivitätsbedingungen zeigen Muscheln bei großem Nahrungsangebot ein schnelles Wachstum und bilden niedrige Schalen- und hohe Weichteilgewichte aus (Innenförde), bei kleinem Nahrungsangebot erfolgt das Wachstum langsam und ist durch hohe Schalen- und niedrige Weichteilgewichte gekennzeichnet (Außenförde). Besonders wichtig für die Muschelernährung ist Nannoplankton und „junger" (noch wenig zersetzter) organischer Detritus. Das gute Sommerwachstum an den Untersuchungsorten ist Ausdruck der bei steigender Wassertemperatur erhöhten Aktivität der Tiere. Im Herbst finden sich bei Muscheln gleicher Länge größere Schalengewichte als im Frühjahr. Das höchste Weichteilgewicht besitzen Miesmuscheln vor Beginn der Laichzeit im Juni. Im Sommer und Herbst wird während der Untersuchungszeit 20-30% der abfiltrierten organischen Substanz als Weichteilgewicht festgelegt (Berechnungen unter Verwendung der Filtrationsraten von THEEDE 1963). Diese Werte erniedrigen sich bei großer Häufigkeit von stark zersetztem organischem Detritus, wie er im Frühjahr an den Untersuchungsorten auftritt.

    Description: Die hydrographischen Verhältnisse des Nord-Ostsee-Kanals werden beschrieben auf Grund von Untersuchungen während zweier Durchfahrten am 5. 10. und 9. 10. 1964. Neben kontinuierlichen Registrierungen des Salzgehaltes, der Temperatur und der Durchsichtigkeit durch Schleppsonden wurden Wasserproben untersucht auf ihren Gehalt an partikulärem Kohlenstoff und Seston. The hydrographic conditions in the Kiel-Canal are described by measurements during two passages on Oct. 5 and Oct 9 1964. Besides continous records of salinity, temperature and transparency by towed in-situ-instruments water samples were analysed for their content of particulate carbon and seston.

    Description: Ligia oceanica lebt in der Ostsee bis etwa an die Salinitätsgrenze 6-7‰. Gegenüber Tieren der Nordsee sind keine strukturellen Änderungen festzustellen. Das Gros der Jungtiere verläßt im Juli-August das Marsupium der Weibchen und wächst bis November auf eine Größe von über 10 mm heran. Diese Tiere sind im nächsten Sommer fortpflanzungsfähig. Nach einer Fortpflanzungsperiode sterben die meisten ab. Nur wenige Tiere werden älter und erreichen Längen über 20 mm. Erwachsene Ligien sind nachtaktiv, junge zeigen eine aperiodisch verteilte Aktivität und sind selbst im hellen Sonnenschein zu sehen. Ihre Vorzugstemperatur liegt höher als die der adulten Tiere. Günstige Nahrung kann ungünstige Salinitätsgrade im Substrat kompensieren; günstige Salzgehalte im Substrat können ungünstige Nahrung ausgleichen. The isopod Ligia oceanica lives on the shores of the Baltic up to a minimum salinity of 6-7‰. Fresh juveniles appear in June, July, and August; one female may produce more than one brood a summer. The young ones reach a length of about 10 mm in November. From then to April-May all Ligiae hide under stones and spend the winter with very little activity. In June, the young reach sexual maturity. After producing one or two broods most of them die (in September-October). A smaller proportion survives another winter; these animals become langer than 20 mm. Ligia oceanica lives upon marine plants and animals that are cast ashore; it may overcome even living animals (smaller Ligiae; Orchestia; Enchytraeidae). The greatest part in the diet of Ligia play brown algae (Fucus). Such food can compensate insufficient salinity of the substratum; good salinity of the substratum (15-30‰) compensates unfavorable food. The osmoregulation of Ligia seems to be part of the energy metabolism.

    Description: Es wird gezeigt, daß interne Wellen in einer inkompressiblen Flüssigkeit mit innerer Reibung und Vermischung nur existieren können, wenn die Schichtung Γ größer als eine minimale Schichtung Γmin ist und daß ihr Auftreten dann auf einen endlichen Wellenlängenbereich beschränkt ist. Die maximale Frequenz ist kleiner als im Fall einer idealen Flüssigkeit (Väisäläfrequenz). Eine Flüssigkeit der obigen Art verhält sich internen Wellen gegenüber wie ein Filter, dessen Bandbreite von den Flüssigkeitseigenschaften und der Schichtung abhängt und dessen maximale Durchlässigkeit bei Wellen liegt, deren horizontale Wellenlänge doppelt so groß wie die vertikale ist. Alle Abweichungen der Eigenschaften interner Wellen (mit Ausnahme des Dämpfungsfaktors) gegenüber denen in einer idealen Flüssigkeit lassen sich als Funktion des Verhältnisses Γ/Γmin darstellen. lt is shown that in an incompressible fluid where viscosity and mixing are present internal waves can exist only when the stratification, Γ, is larger than a minimum value, Γmin, and then only for a finite band of wave lengths. The maximum frequency is smaller than in ideal fluids (Väisälä frequency). Such an incompressible fluid is seen to behave as a filter for internal waves, the band-width of which depends on fluid properties and on stratification, and which has its maximum response for waves having a wave length twice as long in the horizontal as in the vertical direction. All deviations ( except for the damping factor) from the theory of ideal fluids can be expressed as functions of the ratio Γ/Γmin, so that the results can be written in a generalized form which applies to all fluids.
