Marum-Center for Marine Environmental Sciences, University of Bremen, Germany

The university is family-friendly, diverse and sees itself as an international university. We therefore welcome all applicants regardless of gender, nationality, ethnic and social origin, religion/belief, disability, age, sexual orientation and identity.

As the University of Bremen intends to increase the proportion of female employees in science, women are particularly encouraged to apply. Disabled applicants will be given priority if their professional and personal qualifications are essentially the same.

Background

Presently, coastal regions offshore west Sumatra are critical for the development of largescale climate anomalies across the Indian Ocean. Changes in local sea surface and thermocline temperatures area capable of affecting atmospheric convection and rainfall not only in the Indian Ocean realm but also across the globe. However, the role of sea-level in shaping the climate of this region is disputed, both in simulations and in reconstructions. Available records from the eastern Indian Ocean are not suitable to convincingly reconstruct the spatiotemporal patterns of ocean-atmosphere conditions and their relationship to sea-level changes. This endeavor aims to detect whether and how changes in sea-level triggered basin-wide anomalies in circulation and rainfall.

Tasks

Reconstructing the evolution of mean annual sea surface and thermocline temperatures together with rainfall isotopes offshore west Sumatra since the Last Glacial Maximum (LGM). To this end, deuterium isotopes in plant waxes will be measured along with shell Mg/Ca of a surface- and a thermocline-dwelling planktic foraminifera species. In addition, Individual Foraminifera Analysis will be used to assess the range, or stability, of sea surface and thermocline temperatures during five different sea-level stands since the LGM.

Requirements

a PhD in geosciences, chemistry, marine sciences, climate sciences or related fields
experience with inorganic and/or organic geochemistry laboratory
strong analytical chemistry skills
strong English language skills
