Santos *, J.R. Southon, S. Griffin, S.R. Beaupre, E.R.M. Druffel Earth System Science, University of California, Irvine, B321 Croul Hall, Irvine, CA 92697-3100, USA Available online 31 January 2007 Abstract We have developed techniques for accurately and precisely measuring samples containing less than a few hundred micrograms of car- bon, using a compact AMS system (NEC 0.5 MV 1.5SDH-1). Detailed discussions of the sample preparation, measurement setup, data analysis and background corrections for a variety of standard samples ranging from 0.002 to 1 mgC are reported. Multiple aliquots of small amounts of CO2 were reduced to graphite with H2 over pre-baked iron powder catalyst. A reduction reaction temperature of 450 °C was adopted for graphite samples below 0.05 mgC, rather than the usual 550 °C used on samples of 0.1–1 mgC. In our regular reactors (3.1 cm3), this reduction in temperature improved the graphite yield from 60 to 90–100% for samples ranging from 0.006– 0.02 mgC. The combination of lower reaction temperature with a reduced reactor volume (1.6 cm3) gave yields as high as 100% on graphite samples <0.006 mgC. High performance measurements on ultra-small samples are possible also due to a modified NEC MC-SNIC ion-source that generates CÀ currents of 1 lA per lg of carbon for samples in the 0.002 to 0.010 mgC range, combined with on-line measurement of 12C and 13C (AMS d13C) to correct machine-induced isotopic fractionation.

Results emphasize the critically endangered status of this freshwater fish in the upper Rhine River system. © 2010 The Authors Journal compilation © 2010 The Fisheries Society of the British Isles Key words: bottleneck; conservation; Cyprinidae; freshwater fish; microsatellites; population genetics. Climatic oscillations during the Quaternary had an important effect on the actual distribution and the genetic structure of many freshwater fish species, especially in previously glaciated areas due to founder events (Bernatchez, 2001; Ramstad et al., 2004). In addition to natural events, human interactions (such as fisheries, habitat fragmentation and pollution) have imprinted the population genetic structure of many fish species in the recent past (Laroche & Durand, 2004). Combining population genetic data with geographical information, life-history traits of a species and data on past events such as climatic fluctuations or human interference can provide important insights into the factors that shaped the structure of populations, the evolutionary history of a species and its conservation status.

    LUNAR TOPOGRAPHIC ORTHOPHOTOMAP (LTO) AND LUNAR ORTHOPHOTMAP (LO) SERIES (Published by DMATC) Lunar Topographic Orthophotmaps and Lunar Orthophotomaps Scale: 1:250,000 Projection: Transverse Mercator Sheet Size: 25.5”x 26.5” The Lunar Topographic Orthophotmaps and Lunar Orthophotomaps Series are the first comprehensive and continuous mapping to be accomplished from Apollo Mission 15-17 mapping photographs. This series is also the first major effort to apply recent advances in orthophotography to lunar mapping. Presently developed maps of this series were designed to support initial lunar scientific investigations primarily employing results of Apollo Mission 15-17 data. Individual maps of this series cover 4 degrees of lunar latitude and 5 degrees of lunar longitude consisting of 1/16 of the area of a 1:1,000,000 scale Lunar Astronautical Chart (LAC) (Section 4.2.1). Their apha-numeric identification (example – LTO38B1) consists of the designator LTO for topographic orthophoto editions or LO for orthophoto editions followed by the LAC number in which they fall, followed by an A, B, C or D designator defining the pertinent LAC quadrant and a 1, 2, 3, or 4 designator defining the specific sub-quadrant actually covered. The following designation (250) identifies the sheets as being at 1:250,000 scale. The LTO editions display 100-meter contours, 50-meter supplemental contours and spot elevations in a red overprint to the base, which is lithographed in black and white. LO editions are identical except that all relief information is omitted and selenographic graticule is restricted to border ticks, presenting an umencumbered view of lunar features imaged by the photographic base.

  • Lunar Distances Final
    A (NOT SO) BRIEF HISTORY OF LUNAR DISTANCES: LUNAR LONGITUDE DETERMINATION AT SEA BEFORE THE CHRONOMETER Richard de Grijs Department of Physics and Astronomy, Macquarie University, Balaclava Road, Sydney, NSW 2109, Australia Email: [email protected] Abstract: Longitude determination at sea gained increasing commercial importance in the late Middle Ages, spawned by a commensurate increase in long-distance merchant shipping activity. Prior to the successful development of an accurate marine timepiece in the late-eighteenth century, marine navigators relied predominantly on the Moon for their time and longitude determinations. Lunar eclipses had been used for relative position determinations since Antiquity, but their rare occurrences precludes their routine use as reliable way markers. Measuring lunar distances, using the projected positions on the sky of the Moon and bright reference objects—the Sun or one or more bright stars—became the method of choice. It gained in profile and importance through the British Board of Longitude’s endorsement in 1765 of the establishment of a Nautical Almanac. Numerous ‘projectors’ jumped onto the bandwagon, leading to a proliferation of lunar ephemeris tables. Chronometers became both more affordable and more commonplace by the mid-nineteenth century, signaling the beginning of the end for the lunar distance method as a means to determine one’s longitude at sea. Keywords: lunar eclipses, lunar distance method, longitude determination, almanacs, ephemeris tables 1 THE MOON AS A RELIABLE GUIDE FOR NAVIGATION As European nations increasingly ventured beyond their home waters from the late Middle Ages onwards, developing the means to determine one’s position at sea, out of view of familiar shorelines, became an increasingly pressing problem.

These events took place just after what has been termed the “deep Maunder Minimum” but fall within the “extended Maunder Minimum” being in an interval when the sunspot numbers start to recover.

    DEPARTEMENT BAU, VERKEHR UND UMWELT Abteilung Landschaft und Gewässer 28. September 2017 HOCHWASSERSCHUTZ SUHRENTAL Erläuterung für die Anhörung/Mitwirkung zur Anpassung des Richtplans: Festsetzung des Vorhabens 'Hochwasserschutz Suhrental Suhre' (Kapitel L 1.2, Beschluss 5.1); Verminderung der Fruchtfolgeflächen (Kapitel L 3.1, Beschluss 2.2) 1. Ausgangslage Hochwasserereignisse im Suhrental haben in der Vergangenheit immer wieder zu Überschwem- mungen mit Schäden geführt. Im Oberlauf der Suhre im Kanton Aargau beschränken sich Überflu- tungen vor allem auf Landwirtschaftsflächen. Im Unterlauf dagegen sind bei Hochwasserereignissen Siedlungsgebiete betroffen. Erste Bestrebungen, den Hochwasserschutz zu verbessern, wurden bereits vor mehr als 20 Jahren initiiert. Die 2009 erstellte Gefahrenkarte für das Suhrental zeigt eine grosse Anzahl von Schwachstellen in Bezug auf den Hochwasserschutz in den Gemeinden Schöftland, Oberentfelden, Unterentfelden, Suhr und Buchs auf. Die Abflusskapazität ist auf mehr als 2 km im Siedlungsgebiet ungenügend, sodass bei einem hundertjährlichen Hochwasserereignis rund 45 ha Bauzonen mit etwa 600 Gebäu- den und diversen Industrieanlagen betroffen sind. Das Schadenpotenzial bei einem hundertjährli- chen Ereignis beträgt rund 30 Millionen Franken. Auf Antrag des Regionalverbands Suhrental liess das Departement Bau, Verkehr und Umwelt ein Vorprojekt für den Hochwasserschutz im Suhrental ausarbeiten. Bei der Präsentation dieses Vorpro- jekts wurde zusammen mit Landwirtschaft Aargau eine Melioration im Talboden der Suhre in den Gemeinden Attelwil, Moosleerau, Reitnau und Staffelbach angestossen. Als ökologische Aus- gleichsmassnahme des Hochwasserschutzprojekts und der Melioration wird die Suhre zwischen Staffelbach und der Kantonsgrenze zu Luzern revitalisiert. Ein Bauprojekt für das Hochwasserrück- haltebecken in Staffelbach liegt vor. Die Realisierung des Hochwasserrückhaltebeckens Staffelbach erfordert einen Verpflichtungskredit, welcher vom Grossen Rat beschlossen wird (§ 28 Abs.
