    Keywords: Tsunami ; Pacific Ocean
    Description / Table of Contents: The 2011 Tohoku earthquake generated a catastrophic tsunami that killed nearly 20,000 people along the coast of Japan and caused the nuclear disaster at the Fukushima Daiichi Nuclear Power Plant. The tsunami propagated throughout the Pacific Ocean and also affected many other countries, including Russia, the USA, New Zealand, French Polynesia and Chile, demonstrating once again the terrible threat that tsunami waves pose for Pacific countries and the need for basin-wide international scientific collaboration. Following a brief introduction, this volume presents 21 scientific papers, including 12 on aspects of the 2011 Tohoku event. A first group of papers provides detailed field survey results from the coasts of Japan and Russia and examines the wave dynamics on the basis of these surveys, the source mechanism of the earthquake, and the far-field impacts of the Tohoku tsunami. The second group reports on the 2012 tsunamis in El Salvador, the Philippines, off the east coast of Honshu and the landmark Haida Gwaii event off the west coast of British Columbia, Canada, while the papers in a third set discuss a number of remaining challenging questions in tsunami science and warning. The volume will be of interest to scientists and practitioners involved in all aspects of tsunamis from earthquake source processes to transoceanic wave propagation and coastal impacts. Postgraduate students in geophysics, oceanography and coastal engineering – as well as those in the broader geosciences, civil and environmental engineering – will also find the book a valuable resource, as it combines recent case studies with the latest advances in tsunami science and natural hazards mitigation.

    Keywords: Tsunami ; Indian Ocean
    Description / Table of Contents: Ten years ago, on December 26, 2004, one of the world’s most destructive natural disasters occurred. A magnitude Mw 9.1 earthquake (third strongest ever instrumentally recorded) generated a global tsunami that killed about 230,000 people along the coasts of 14 countries in the Indian Ocean and propagated as far as the North Pacific and North Atlantic Oceans. Since then, various countries from around the globe contributed major funding to tsunami research and mitigation, enabling the installation of hundreds of new high-precision instruments, the development of new technology and the establishment of more modern communication systems. As a result, incredible progress has been achieved in tsunami research and operation during the ten years after the 2004 Indian Ocean tsunami. The papers presented in this second of two special volumes of Pure and Applied Geophysics reflect the state of tsunami science during this time, including two papers devoted to global observations. Five papers provide new findings specifically in the Indian Ocean. Eight papers cover Pacific Ocean studies, focusing mainly on the 2011 Tohoku earthquake and tsunami. Remaining papers in the volume describe studies in the Atlantic and Mediterranean and general tsunami source studies. The volume is of interest to scientists and practitioners involved in all aspects of tsunamis from earthquake source processes to transoceanic wave propagation and coastal impacts. Postgraduate students in geophysics, oceanography and coastal engineering – as well as students in the broader geosciences, civil and environmental engineering – will also find the book to be a valuable resource, as it combines recent case studies with advances in tsunami science and natural hazards mitigation.

    Description / Table of Contents: Summary A volumetric procedure has been described for determining the hydrogen content of organic compounds in the form of sulfuric acid. The combustions were conducted in the presence of sulfur, sulfur dioxide, or carbon disulfide in an oxygen atmosphere. Sulfur dioxide is oxidized to sulfur trioxide on a platinum catalyst in the combustion tube, and the water resulting from the combustion combines with the sulfur trioxide formed to yield concentrated sulfuric acid. This condenses in an absorption vessel attached to the combustion tube. Any excess sulfur trioxide is expelled from the oleum during the purging period by warming. After the absorber has been swept out, the sulfuric acid equivalent to the hydrogen content of the samples is titrated acidimetrically.
    Abstract: Résumé On présente une méthode volumétrique pour déterminer la teneur en hydrogène de composés organiques, sous forme d'acide sulfurique. Les combustions s'effectuent en présence de soufre, d'anhydride sulfureux ou de sulfure de carbone en atmosphère d'oxygène. L'anhydride sulfureux est oxydé en anhydride sulfurique sur catalyseur au platine placé dans le tube à combustion. Il se forme ensuite de l'acide sulfurique concentré au contact de l'eau produite par la combustion. Celle-ci se condense dans un récipient pour absorption relié au tube à combustion. On chasse l'anhydride sulfurique en excès de l'oléum pendant la période de balayage, par échauffement. Après balayage de l'absorbeur on titre par acidimétrie l'acide sulfurique équivalent à la teneur en hydrogène de l'échantillon.
    Notes: Zusammenfassung Eine volumetrische Methode zur Bestimmung des Wasserstoffgehaltes organischer Verbindungen in Form von Schwefelsäure wird dargelegt. Die Verbrennungen werden in Gegenwart von Schwefel, Schwefeldioxid oder Schwefelkohlenstoff in Sauerstoffatmosphäre durchgeführt. Das Schwefeldioxid wird an dem im Verbrennungsrohr untergebrachten Platinkatalysator zu Schwefeltrioxid oxydiert, das mit dem bei der Verbrennung entstandenen Wasser konz. Schwefelsäure bildet. Diese kondensiert in einem dem Verbrennungsrohr angeschlossenen Absorptionsgefäß. Das überschüssige Schwefeltrioxid vertreibt man aus dem Oleum im Laufe der Spülungsperiode durch Erwärmen. Nach der Ausspülung des Absorbers wird die dem Wasserstoffgehalt der Proben äquivalente Schwefelsäure acidimetrisch titriert.

    Description / Table of Contents: Summary A new method for the iodometric determination of the hydrogen content of organic materials has been described. The sample is mixed with powdered sulfur and decomposed at 1200° C in a stream of nitrogen over quartz wool or a platinum-quartz wool catalyst. The sulfur-bearing pyrolysis products yield hydrogen sulfide that is then, absorbed in a zinc sulfate-sodium acetate solution and titrated iodometrically. The optimal reaction conditions were thoroughly studied and also explained from the theoretical standpoint.
    Notes: Zusammenfassung Eine neue Methode zur jodometrischen Bestimmung des Wasserstoffgehaltes organischer Verbindungen wird beschrieben. Die Probe wird mit Schwefelpulver vermischt und bei 1200° C im Stickstoff strom über Quarzwolle oder einem Platin- Quarzwollekatalysator zersetzt. Aus den schwefelhaltigen Pyrolyseprodukten bildet sich Schwefelwasserstoff, der in einer Zinksulfat-Natriumacetatlösung absorbiert und jodometrisch titriert wird. Die optimalen Reaktionsbedingungen wurden eingehend untersucht und auch in theoretischer Hinsicht erklärt.

    Description: Goal of the project CARIBIC (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrumented Container) is to carry out regular and detailed observations of atmospheric composition (particles and gases) at cruising altitudes of passenger aircraft, i.e. at 9 – 12 km. Mercury has been measured since May 2005 by a modified Tekran instrument (Tekran-Analyzer Model 2537 A, Tekran Inc., Toronto, Canada) during monthly intercontinental flights between Europe and South and North America, Africa and Asia. Here we describe the instrument modifications, the post-flight processing of the raw Tekran signal, and the speciation experiments.

    Description: After more than a decade of recurring tsunamis, identification of tsunami deposits, a part of hazard characterization, still remains a challenging task not fully understood. The lack of sufficient monitoring equipment and rare tsunami frequency are among the primary obstacles that limit our fundamental understanding of sediment transport mechanisms during a tsunami. The use of numerical simulations to study tsunami-induced sediment transport was rare in Indonesia until the 2004 Indian Ocean tsunami. This study aims to couple two hydrodynamic numerical models in order to reproduce tsunami-induced sediment deposits, i.e., their locations and thicknesses. Numerical simulations were performed using the Cornell Multi-Grid Coupled Tsunami Model (COMCOT) and Delft3D. This study reconstructed tsunami wave propagation from its source using COMCOT, which was later combined with Delft3D to map the location of the tsunami deposits and calculate their thicknesses. Two Dimensional-Horizontal (2DH) models were used as part of both simulation packages. Lhoong, in the Aceh Besar District, located approximately 60 km southwest of Banda Aceh, was selected as the study area. Field data collected in 2015 and 2016 validated the forward modeling techniques adopted in this study. However, agreements between numerical simulations and field observations were more robust using data collected in 2005, i.e., just months after the tsunami (Jaffe et al., 2006). We conducted pit (trench) tests at select locations to obtain tsunami deposit thickness and grain size distributions. The resulting numerical simulations are useful when estimating the locations and the thicknesses of the tsunami deposits. The agreement between the field data and the numerical simulations is reasonable despite a trend that overestimates the field observations.
