Two PhD positions are currently available in the Carl-von-Ossietzky University Oldenburg. Both roles are available for a period of three years, commencing on 1 January 2018, and ending on 31 December 2020. Regular marine expeditions will be an essential part of both roles, and each candidate will have to possess fluency in both written and spoken English, alongside excellent communication and presentation skills.
Position #1: The first PhD position focuses on the consequences of the shift from krill to salps for nutrient stoichiometry and microbial food web dynamics, including bacteria, phytoplankton and microzooplankton. ICBM are looking for a candidate holding an outstanding academic university degree in Marine Environmental Science, Ecology or a closely related subject. The candidate must have a strong background in ecological principles and expertise in experimental ecology, DNA-based molecular techniques, statistical data analysis, and good writing skills. Additionally, experience in organizing and conducting experimental work on research cruises, in handling phyto- and zooplankton organisms and in investigating trophic interactions involving nutrient cycling / ecological stoichiometry is required. The successful candidate will be embedded in the working group 'Planktology' of the ICBM (Wilhelmshaven) and will be supervised by Dr. Stefanie Moorthi and Prof. Helmut Hillebrand.
Position #2: The second PhD position focuses on the consequences of the shift from krill to salps for the biological carbon pump (e.g. fecal pellet production, sinking rates, estimation of degradation processes in relation to quality of ingested food). The successful candidate is expected to have an outstanding academic university degree in marine biology and should have skills in analytical techniques, experimentation/maintenance of marine organisms, and preferably analytical skills in physiology and molecular biology. The position requires the ability to manage month-long research expeditions and to work self-reliant on the project. The successful candidate will be embedded in the working group 'Biodiversity and Biological Processes in Polar Seas', headed by Prof. Dr. Bettina Meyer in close cooperation with the Helmholtz Young Investigator Group 'SeaPump' at AWI, Marum, and University of Bremen, headed by Dr. Morten Iversen.
