    In:  Supplement to: DeMaster, David J; Cochran, James R (1982): Particle mixing rates in deep-sea sediments determined from excess 210Pb and 32Si profiles. Earth and Planetary Science Letters, 61(2), 257-271, https://doi.org/10.1016/0012-821X(82)90057-7
    Publication Date: 2024-04-19
    Description: Particle mixing rates have been determined for 5 South Atlantic/Antarctic and 3 equatorial Pacific deep-sea cores using excess 210Pb and 32Si measurements. Radionuclide profiles from these siliceous, calcareous, and clay-rich sediments have been evaluated using a steady state vertical advection diffusion model. In Antarctic siliceous sediments210Pb mixing coefficients (0.04-0.16 cm**2/y) are in reasonable agreement with the 32Si mixing coefficient (0.2 or 0.4 cm**2/y, depending on 32Si half-life). In an equatorial Pacific sediment core, however, the 210Pb mixing coefficient (0.22 cm**2/y) is 3-7 times greater than the 32Si mixing coefficient (0.03 or 0.07 cm**2/y). The difference in 210Pb and 32Si mixing rates in the Pacific sediments results from: (1) non-steady state mixing and differences in characteristic time and depth scales of the two radionuclides, (2) preferential mixing of fine-grained clay particles containing most of the 210Pb activity relative to coarser particles (large radiolaria) containing the 32Si activity, or (3) the supply of 222Rn from the bottom of manganese nodules which increases the measured excess 210Pb activity (relative to 226Ra) at depth and artificially increases the 210Pb mixing coefficient. Based on 32Si data and pore water silica profiles, dissolution of biogenic silica in the sediment column appears to have a minor effect on the 32Si profile in the mixed layer. Deep-sea particle mixing rates reported in this study and the literature do not correlate with sediment type, sediment accumulation rate, or surface productivity. Based on differences in mixing rate among three Antarctic cores collected within 50 km of each other, local variability in the intensity of deep-sea mixing appears to be as important as regional differences in sediment properties.

    Description: Seit gut 20 Jahren wird die Grundwassernutzung im Rahmen des "New Valley Project" stark vorangetri eben . Um eine langfristige Funktionsfähigkeit der Entwicklungsprojekte zu gewährleisten, mußte die Frage der Grundwasserbildung und -herkunft geklärt werden. Radiokarbon-Altersbestimmungen, Isotopenuntersuchungen und hydrochemische Analysen zeigen, daß das Grundwasser des Dakhl a-Beckens fossil ist; eine rezente Grundwasserneubildung ist nicht nachzuweisen. Grundwasserbildung fand letztmals während des letzten Hauptpluvials (〉20.000 Jahre B.P. ) statt, postpluviale Grundwässer wurden nicht nachgewiesen. Das Grundwasser wurde aus Niederschlägen atlantischer Feuchtmassen gebildet, die über eine Westwinddrift in die östliche Sahara gelangten. Die Grundwasserbildung war weitgehend lokal, großräumige Grundwasserbewegung findet nicht statt. Die Möglichkeit von Überläufen fossiler Grundwässer aus Nachbarbecken, wie Nordsudan-Becken und Kufra -Becken , konnte nicht geklärt werden. Aufgrund der analytischen Untersuchungen ist der Aquifer des Dakhl a-Beckens weder regional noch vertikal gliederbar; seine Ausbildung ist bei großräumiger Betrachtung sehr homogen. Wegen der ungleichen Verteilung der Informationen im Dakhla-Becken wurde zur Grundwassermassenberechnung ein dreidimensionales Computermodell entwickelt, das über Regressionen mit Polynomen höherer Ordnung die Volumina des Aquifers errechnete. Soweit überprüfbar, erbrachte das Modell gute Ergebnisse, so daß es künftig auch in Becken angewandt werden kann, von denen noch weniger Informationen vorliegen. Es wurde ein Zeit-Volumen-Modell erstellt, das zum einen den Absenkungsverlauf des Grundwasserspiegels beschreibt, zum anderen die zur Klärung der Grundwassersituation verwendeten Parameter stützt und sie als weitgehend richtig ausweist.
    Description: For about twenty years the use of the groundwater has been increased closely within the frame of the "New Valley Project". The questions of the formation and origin of the groundwater had to be elucidated in order to insure the long time function of the project. The investigations of isotopes, radiocarbon age dating and the hydrochemical analyses indicate the groundwater of the Dakhla Basin to be fossil; a recent formation of groundwater may safely be excluded. The last time groundwater formation occurred was during the last main pluvial (〉20,000 B.P.); there are no indications of postpluvial formation. The groundwater was formed by the precipitation of Atlantic humid air masses which reached the eastern Sahara by western drift. The groundwater formation was mainly local, regional groundwater movement does not occur. The possible overfl ow of fossil groundwater from the neighbouring basins as the North Sudan Basin and the Kufra Basin could not be clarified. Analytical investigations show the aquifer of the Dakhla Basin neither regionally nor vertically divisible; the shape is very nomogeneous over large regions. Since informations about the Dakhla Basin are distributed unevenly for the calculation of the groundwater masses the volumes of the aquifer were calculated using a three dimensional Computer model working with polynomal regressions of higher order. As far as possible the model shows good results; therefore it can be used in the future in basins with even less informations. A model of time and volume was made describing the decrease of the waterhead; the same model supports the Parameters used for the analysis of the groundwater Situation indicating that the Parameters are correct.
