Zusammenfassung Die starke Abhängigkeit der zeitlichen Folge erdmagnetischer Störungen und Erdbehen von einer Periode 34 ^d .19 wird an den Diagrammen der Figg. 1–5 veranschaulicht. Nach der harmonischen Analyse tritt die Periodenwelle in zwei bestimmten, um 180° gegeneinander versetzten Phasenlagen auf. Ein Vergleich der Amplituden mit derSchusterschen Expektanz lässt erkennen, dass ein Walten des Zufalls hierbei praktisch ausgeschlossen sein sollte. Die Periode ist identisch mit der vom Verfasser früher abgeleiteten Rotationsdauer 34 ^d .19 eines hypothetischen Sonnenkerns. Auch Perioden der Form treten auf ( _p =Umlaufszeit der einzelnen Planeten), wie hier nur an einem Beispiel für den Merkur (Fig. 7) gezeigt wird.

Summary It is shown in the diagrams Figg. 1–5, that the temporal sequences of terrestrial magnetic storms and earthquakes are largely dependent from a period of 34.19 days. The harmonic analyse demonstrates, that there are two waves of this period with a difference of 180° between them. The comparison of the amplitudes of waves with the expectance as defined byA. Schuster shows, that the period should be a reality. This period is identical with the period of 34.19 days for the rotation of an hypothetical sun-core, discovered earlier by the author. It is illustrated only at the example of the planet Mercury (Fig. 7), that there exist also periods of the form: ( _p =period of the revolution of the single planet).

Sur l'influence de la loi de répartition des densités à l'intérieur de la Terre dans les variations luni-solaires de la gravité en un point     

Dr. Paul J. Melchior 《Pure and Applied Geophysics》1950,16(3-4):105-112

Résumé Les observations des variations luni-solaires de la gravité en divers points du globe ne donnent pas des valuers très concordantes pour le facteur lié au module de rigidité de la Terre. On démontre ici que la répartition croissante des densités vers le centre de la Terre a pour conséquence d'amplifier encore les effets dus à l'élasticité. En adoptant la répartition deBullen, on aurait =1+0.244h>1, (h étant le premier nombre deLove). En outre une relation simple lie les facteurs et (déviations de la verticale). La valuer deh déduite de telles observations ne peut conduire directement à une valeur significative du module de rigidité du globe car il faut encore tenir compte des variations de la période et de l'amplitude du mouvement chandlérien du pôle.

Summary Observations of luni-solar variations of gravity at various points of the Earth do not give values in agreement for the factor bound to the Earth's modulus of rigidity. It is shown here that the law of increasing of density toward the center of the Earth emphasizes the effect of elasticity: following the law ofBullen, we should have =1+0.244h>1, (h is the firstLove's number). Further, there is a simple relation between the factors and (deviations of the vertical). The value ofh deduced from such observations could not give directly a significative value of the modulus of rigidity because we must take into account the variations of period and amplitude of the chandlerian motion of the pole.

Riassunto Le osservazioni delle variazioni luni-solari della gravità in diversi punti della Terra non dànno valori concordanti per il fattore legato al modulo di rigidità del Globo. Si dimostra che la ripartizione crescente della densità verso il centro della Terra ha per conseguenza di amplificare ancora gli effetti dell'elasticità; adottando la legge diBullen, abbiamo =1+0.244h>1, (h essendo il primo numero diLove). Inoltre, una semplice relazione lega i fattori e (deviazioni della verticale). Il valore dih dedotto da tali osservazioni non può condurre ad un valore significativo del modulo di rigidità del Globo poiché bisogna considerare anche le variazioni del periodo e dell'ampiezza del moto polare diChandler.

Overview of GIS Applications in Estuarine Monitoring and Assessment Research   总被引：1，自引：0，他引：1  

John F. Paul  Jane L. Copeland  Michael Charpentier  Peter V. August  Jeffrey W. Hollister 《Marine Geodesy》2003,26(1):63-72

Geographic information systems (GIS) tools are now considered integral in estuarine monitoring and assessment research. A synopsis is presented of our estuarine applications of GIS in the Northeast region of the U.S. The applications discussed cover sample site selection, support for field sampling activities, quality assurance of data, spatial display of geographic referenced information, quantitative spatial analysis of data, and communication of results.  相似文献   

Predator-Prey Interaction between two Competing Sea Star Species of the Genus Astropecten     

Paul H.  Schmid Rolf  Schaerer 《Marine Ecology》1981,2(3):207-214

Abstract. The predator-prey interaction between two sea star species of the genus Astropecten known to be competitors was investigated at Costa Colostrai, Sardinia, Italy by means of SCUBA-Diving. It was estimated that predation of A. aranciacus would eliminate about 1 % of the prey population of A. bispinosus daily. Because densities of A. bispinosus were observed to be unaltered during the summer months, a considerable immigration of A. bispinosus into the area has to be postulated. A. bispinosus represents 40% of the dry organic matter consumed by A. aranciacus , and is one of the most important food items of this species.
A. aranciacus is not more efficient in preying upon A. bispinosus than in preying upon other food items; but efficiency is greater upon buried sea stars than upon walking ones.
Consequences for stability of the local ecosystem are discussed.  相似文献   

Comparison of Ocean Surface Wind Stress Computed with Different Parameterization Functions of the Drag Coefficient     

Paul A. Hwang 《Journal of Oceanography》2005,61(1):91-107

Depending on the choice of reference wind speed, the quantitative and qualitative properties of the drag coefficient may vary. On the ocean surface, surface waves are the physical roughness at the air-sea interface, and they play an important role in controlling the air-sea exchange processes. The degree of dynamic influence of surface waves scales with wavelength. Drag coefficient computed with the reference wind speed at an elevation proportional to the wavelength (for example, U _λ/2) is fundamentally different from the drag coefficient computed with the wind speed at fixed 10 m elevation (U ₁₀). A comparison has been carried out to quantify the difference in wind stress computation using several different parameterization functions of the drag coefficient. The result indicates that the wind stress computed from U ₁₀ input using a drag coefficient referenced to U _λ/2 is more accurate than that computed with drag coefficient functions referenced to U ₁₀.  相似文献   

Bowers Swell: Evidence for a zone of compressive deformation concentric with Bowers Ridge, Bering Sea     

Michael S. Marlow  Alan K. Cooper  Shawn V. Dadisman  Eric L. Geist  Paul R. Carlson 《Marine and Petroleum Geology》1990,7(4)

Bowers Swell is a newly discovered bathymetric feature which is up to 90 m high, between 12 and 20 km wide, and which extends arcuately about 400 km along the northern and eastern sides of Bowers Ridge. The swell was first revealed on GLORIA sonographs and subsequently mapped on seismic reflection and 3.5 kHz bathymetric profiles. These geophysical data show that the swell caps an arcuate anticlinal ridge, which is composed of deformed strata in an ancient trench on the northern and eastern sides of Bowers Ridge. The trench fill beneath the swell is actively deforming, as shown by faulting of the sea floor and by thinning of the strata across the crest of the swell. Thinning and faulting of the trench strata preclude an origin for the swell by simple sediment draping over an older basement high. We considered several models for the origin of Bowers Swell, including folding and uplift of the underlying trench sediment during the interaction between the Pacific plate beneath the Aleutian Ridge and a remnant oceanic slab beneath Bowers Ridge. However, such plate motions should generate extensive seismicity beneath Bowers Ridge, which is aseismic, and refraction data do not show any remnant slab beneath Bowers Ridge. Another origin considered for Bowers Swell invokes sediment deformation resulting from differential loading and diapirism in the trench fill. However, diapirism is not evident on seismic reflection profiles across the swell. We favour a model in which sediment deformation and swell formation resulted from a few tens of kilometers of low seismicity motion by intraplate crustal blocks beneath the Aleutian Basin. This motion may result from the translation of blocks in western Alaska to the south-west, forcing the movement of the Bering Sea margin west of Alaska into the abyssal Aleutian Basin.  相似文献
