Energy transfers in gravity plumes
For the project “Energy transfers in gravity plumes” within the DFG-funded collaborative research center TRR 181 “Energy transfers in Atmosphere and Ocean", University of Bremen invites applications for a
PhD Position physical oceanography
The employment is fixed-term and governed by the Act of Academic Fixed-Term Contract, §2 I (Wissenschaftszeitvertragsgesetz – WissZeitVG). Therefore, candidates may only be considered for appointment if they still have
the respective qualification periods available in accordance with § 2 (1) WissZeitVG.
Motivation: Dense gravity plumes play a major role in both the ventilation of the deep ocean and the global ocean circulation. Often they are associated with rapid water mass modification due to vigorous mixing and entrainment
of ambient water. The overflow plume immediately downstream of Denmark Strait is a prototype example for the occurrence of such processes. The project aims at understanding the pathways and processes by which energy is transferred from the mesoscale eddy field
to dissipative turbulent scales within this plume. Using observational and numerical modelling efforts we will identify locations of entrainment hot spots, physical processes involved, plume-eddy and plume-topography interaction driving energy transfer across
the scales, gravity wave dissipation, vertical current shear.
Framework: This project represents a collaboration between the Institut für Meereskunde (IfM) at the University of Hamburg, the Alfred-Wegener Institute for Polar and Marine Sciences (AWI) and MARUM at Bremen University. Details about the TRR 181 are available
Project description: You will focus your research on (i) the interaction of the overflow plume with transient eddies associated with the entrainment of ambient waters and (ii) turbulent mixing arising from plume-topography interaction. The work is based on
both existing mooring records and new measurements to be conducted during the project. Informed by the observations in the Denmark Strait overflow plume, you will analyse outputs from idealized model configurations with very high resolution (grid spacing less
than 50-100 m) and non-hydrostatic dynamics and assess the amount of mixing associated with both passing eddies and flow-topography interactions.
We are searching for an enthusiastic and committed researcher with a keen interest in ocean observations and ocean dynamics. You will be employed by Bremen University and will be based in the Physical Oceanography group at AWI in Bremerhaven, working under
the supervision Prof. Dr Torsten Kanzow (AWI / Bremen University), Dr Martin Losch (AWI) and Dr Kerstin Jochumsen (Hamburg University). As a PhD student you will be enrolled at the Department of Physics, University of Bremen. Bremen University offers several
postgraduate frameworks (GLOMAR, ArcTrain) with a large variety of (optional) courses and a vibrant PhD community.
Completed MSc or equivalent in physical oceanography, meteorology, physics, applied mathematics or related fields
Advanced programming skills (MATLAB); experience with observation-based data sets is of advantage
Interest in independent research, data analysis, presentation and publication of scientific results
Applicants should have excellent English skills and enjoy working in an international and interdisciplinary team.
The position is for a fixed term of 3 years. It is funded by the German Science Foundation (DFG). The starting date is January 1st, 2017. Salary corresponds to 2/3 TV-L E13.
Applicants should submit under the reference number A197/16 their letter of motivation, a CV including copies of certificates, a publication list if applicable, and contact information of two referees. Documents. The call is open until the position is filled.
The review of applications will commence on October 1st 2016.
As the University of Bremen intends to increase the proportion of female employees in science, women are particularly encouraged to apply. In case of equal personal aptitudes and qualification priority will be given to disables persons. The University of Bremen
explicitly invites persons with migration background to apply.
Disabled persons with the same professional and personal qualifications will be given preference.
