Leibniz Institut für Meereswissenschaften in Kiel (IfM-Geomar), Germany Posted 31 July 2007 Topic:“The influence of Fe on the distribution and kinetic speciation of Zn, Cd, Co and Ni in the Southern Ocean”. Recent research has clearly demonstrated the role of iron supply in controlling primary productivity in the Southern Ocean and in turn the cycling of other key bio-elements (Co, Ni, Cd and Zn). It is now also clear that these other elements play a role in controlling the species composition of phytoplankton and importantly the rates at which macronutrients are consumed by phytoplankton. These changes in rates of uptake are then reflected as differences in the nutrient ratios, or metal to nutrient ratios, of the phytoplankton themselves. Understanding of these processes is thus critical for investigations into the primary productivity of the Southern Ocean and the sources and sinks for major nutrients. This project forms part of a comprehensive IPY GEOTRACES program and is focused on the chemical speciation and distribution of the key bio-elements (Co, Ni, Cd and Zn) over a range of different Fe and macronutrient conditions. The PhD student will utilize state of the art techniques (FIA-chemiluminescence, Voltammetry) for laboratory and shipboard determination of trace metal speciation in the Southern Ocean, starting with a cruise in early 2008. While experience in analytical chemistry would be an advantage, applications from students with bioscience or geoscience background are also welcome. Applications close 14 September 2007, and the candidate should be able to commence the project shortly thereafter. Candidates should have a good knowledge of either English or German.

Dayton St, Suite 1511 Madison, WI 53703 608 262 4817 Utrecht University, the Netherlands Posted 11 June 2007 We seek a candidate for a PhD position at Utrecht University within a recently funded program entitled: Niche engineering and the evolution of biogeochemical cycles through time. Modern marine environments are characterized by complex faunal communities living in the sediment with densities and diversities that vary depending on sediment type, availability of oxygen and organic matter load arriving at the sea bottom. Some species play an extraordinary role in creating suitable environments for other taxa to live in. These keystone species, for example deep burrowing lugworms, are regarded as niche engineers. Through geological history, origination of such niche engineers is hypothesized to have lead to sudden bursts in evolution of other infaunal taxa. This program is integrated in the Darwin Center for Biogeology, and will be performed in close cooperation with the Microbial Ecology group at the Netherlands Institute of Ecology (NIOO-KNAW, Yerseke). The program has 2 projects, each project carried out by a PhD student. Currently, we are looking for a candidate for the PhD position concerning the project: The effects of bioirrigation on benthic foraminifera. The aim of this project is to study the effects of the presence of various types of niche engineers on the surrounding meiofauna, in particular the foraminiferal population, and on biogeochemical cycling. Bioturbation, burrow ventilation, bioirrigation and grazing are activities that may have a significant impact on the vertical distribution of benthic foraminifera in marine sediments. Alternatively, foraminifera seems to have a considerable impact on the bacterial population and, consequently, the biogeochemistry. The project will involve laboratory experiments with the coupled system biogeochemistry-bacteria-foraminifera in sediment cores with different imposed biogeochemical conditions, and with or without artificial bioirrigation. It also involves field sampling of marine sediments (Wadden Sea). This project will be supported by ongoing modeling work within the research groups of Stratigraphy/Paleontology at Utrecht University and Microbial Ecology group at NIOO-KNAW. Qualifications: We are looking for a highly motivated individual with excellent communication skills who is interested in interdisciplinary research combining various fields of biogeology and an MSc in an appropriate field. Terms of employment: We offer a full-time PhD position for 4 years, with monthly salary starting at €1956,- in the first year to €2502,- in the last year of appointment. We also offer a pension scheme, a collective health insurance and flexible employment conditions. Conditions are based on the Collective Employment Agreement of the Dutch Universities and are supplemented with a holiday allowance of 8 % per year and a year-end bonus of 3%.
