************************************************************************* From: Baerbel Langmann <baerbel.langmann@xxxxxxx> ************************************************************************* PhD Position Vacancy The University of Hamburg jointly with the Max Planck Institute for Meteorology and the Institute for Coastal Research at the GKSS Research Centre is establishing a trans-disciplinary research focus on “Integrated Climate System Analysis and Prediction, CliSAP”. The goal is to analyze ongoing and past changes of the state of the climate system, in response to natural and human-driven perturbations, to determine predictable elements of the climate system over a broad range of space and time scales, and to determine uncertainties intrinsic to predictions of important climate system and environmental indices (see www.clisap.de). The Cluster of Excellence (CliSAP) invites applicants for the following sub-project: Volcanic iron bio-availability and its climate impact Explosive volcanism in the subduction zones produces large eruption columns providing relatively long time for volcanic ash and gas/aerosol interactions, thereby favouring soluble salt formation on ash surfaces. Different processes especially in the volcanic plume are assumed to contribute to the transformation of insoluble iron into soluble salts which get attached to volcanic ash particles. When volcanic ash deposition into the ocean takes place, such processes make volcanic iron bio-available for the marine biogeochemical iron cycles where it may affect phytoplankton production and consequently climate through carbon dioxide uptake by the ocean. This project focuses on the heterogeneous chemical and microphysical processes that occur in a volcanic plume and convert insoluble iron compounds in water soluble form. For this project, the university has a 65% FTE (25 hours/week) position open for a research associate (wissenschaftliche/r Mitarbeiter/in) - salary group 13 TV-L - with a starting date of 1.7.2009. The short-term, 3-year contract will end on 30.6.12, in accordance with §§ 27, 28 Hamburg Higher Education Law (Hamburgisches Hochschulgesetz); see also § 2 of the Academic Fixed-Term Contract Law (Wissenschaftszeitvertragsgesetz). The university intends to increase the number of women amongst its academic personnel and expressly encourages qualified women to apply. In compliance with the Hamburg Equal Opportunity Law, preference will be given to qualified female applicants. General Responsibilities: A research associate’s duties include academic service in the project “Volcanic iron bio-availability and its climate impact”. Within this framework associates have the opportunity to further their academic education, in particular through the completion of a doctoral dissertation. The data obtained in the project may be used for the dissertation. The PhD students will participate in CliSAP’s “School of Integrated Climate System Science (SICSS)”. Specific Area(s) of Responsibility: In order to better constrain the production of these salts the successful candidate will extend the volcanic plume model ATHAM with modules describing the involved heterogeneous iron chemistry. Parameter studies will be carried out in order to constrain favourable and unfavourable conditions for the development of bio-available iron. The model will be tested against available data sets from the eruption of Mt. Pinatubo and Kasatochi volcano. Other candidates for testing the model have to be identified during the thesis. Requirements: Academic degree in an academic subject area qualifying the holder to carry out the above-mentioned responsibilities. Knowledge of a programming language (Fortran) as well as experience in programming in particular under Unix / Linux are a major plus. Applications (including information about the received degree and the current CV) should be sent to: Universität Hamburg KlimaCampus CliSAP Office Code/Reference number 08/2-024 Grindelberg 5 20144 Hamburg or to office.clisap@xxxxxxx The deadline for receipt of applications is 25.5.09. For additional information please contact Dr. B. Langmann (baerbel.langmann@xxxxxxx) or Prof. Dr. M. Hort (Matthias.hort@xxxxxxx) or see the website www.geophysics.zmaw.de for general information on the volcanological reseach in the framework of CLISAP. Preference will be given to disabled applicants with equal qualifications. ============================================================== To unsubscribe from the volcano list, send the message: signoff volcano to: listserv@xxxxxxx, or write to: volcano-request@xxxxxxxx To contribute to the volcano list, send your message to: volcano@xxxxxxxx Please do not send attachments. ==============================================================
