Crustal displacements due to continental water loading

Authors : van Dam, T; Wahr, J; Milly, PCD; Shmakin, AB; Blewitt, G; Lavallee, D; Larson, KM Source : GEOPHYSICAL RESEARCH LETTERS 28 (4):651-654 2001 Abstract : The effects of long-wavelength (> 100 km), seasonal variability in continental water storage on vertical crustal motions are assessed. The modeled vertical displacements (Deltar(M)) have root-mean-square (RMS) values.. Lire la suite

Secular changes of LOD associated with a growth of the inner core

Author(s) : Denis, C; Rybicki, KR; Varga, P Source : ASTRONOMISCHE NACHRICHTEN 327 (4):309-313 2006 Abstract : From recent estimates of the age of the inner core based on the theory of thermal evolution of the core, we estimate that nowadays the growth of the inner core may perhaps contribute to the observed overall secular..

Comment on the paper « Fast tidal cycling and the origin of life » by Richard Lathe

Author(s) : Varga, P; Rybicki, KR; Denis, C Source : ICARUS 180 (1):274-276 2006 Abstract : We show that the fast tidal cycling postulated by Lathe [Lathe, R., 2004. Icarus 168, 18-22] is not a plausible mechanism to explain the origin of life on Earth about 3.9 Ga ago. The value of LOD at this.. Lire la suite

Variation in the rotation rate of the earth and the geomagnetic field

Author(s) : Varga, P; Bus, Z; Sule, B; Schreider, A; Bizouard, C; Gambis, D; Denis, C Source : ACTA GEODAETICA ET GEOPHYSICA HUNGARICA 42 (4):433-448 2007 Abstract : In its first part this work focuses on connection of length of day (LOD) with centered and eccentric geomagnetic dipole fields described with the use of Gaussian..

Taxonomy, morphology and phylogeny of Lower Jurassic loligosepiid coleoids (Cephalopoda)

Author(s) : Fuchs, D; Weis, R Source : NEUES JAHRBUCH FUR GEOLOGIE UND PALAONTOLOGIE-ABHANDLUNGEN 249 (1):93-112 2008 Abstract : Until today, gladii of loligosepiid vampyropods have been difficult to distinguished owing to their fragmentary state of preservation. Re-study of a large set of loligosepiids from different Lower Jurassic localities has shown that the preservation of.. Lire la suite

Author(s) : Fuchs, D; Bracchi, G; Weis, R Source : PALAEONTOLOGY 5265-81 2009 Abstract : Three previously unknown octopods are described from Upper Cenomanian limestones of the Haqel and Hadjoula localities (Lebanon). Keuppia levante gen. nov., sp. nov., Keuppia hyperbolaris gen. nov,. sp. nov. and Styletoctopus annae gen. nov, . sp. nov. are regarded as.. Lire la suite

Particle size and mineralogical composition of inorganic colloids in waters draining the adit of an abandoned mine, Goesdorf, Luxembourg

Author(s) : Filella, M; Chanudet, V; Philippo, S; Quentel, F Source : APPLIED GEOCHEMISTRY 24 (1):52-61 2009 Abstract : Particle size distributions and the mineralogy of inorganic colloids in waters draining the adit of an abandoned mine (Goesdorf, Luxembourg) were quantified by single particle counting based on light scattering (100 nm-2 pm) combined with transmission..
