Autonomous voltametric and potentiometric sensors: toward long-term monitoring of sulphur dynamics at redox-interfaces
Under the frame of the European Community Initial Training Network SENSENET, we are seeking a candidate for a PhD with a background in analytical chemistry/marine chemistry/ biogeochemistry, or sensor development in environmental science and technology.
The PhD will be hosted at the Oceanological Observatory of Banyuls-sur-Mer, a marine station from the University of Pierre et Marie Curie-Paris 6 (UPMC) (http://www.obs-banyuls.fr). Candidate should be preferentially EC-resident (excluding French) and should have stayed less than 9 months in France in the past 5 years.
The project aims to further develop in situ electrochemical methods for the monitoring of deep and shallow marine environments. Electrochemical techniques have proven to be particularly relevant for the monitoring of dynamic redox interfaces (e.g.: sulphidic sediments associated with hydrothermal vents, methane seeps or organic matter degradation), but they still need improvement for long-term use.
The work will be based on recently validated in situ autonomous sensors for reduced sulphur species. The objective is to improve current voltammetric and potentiometric methods and electrode design to optimize measurement temporal stability. Validation of the methods will be performed on field-test stations at variable depth. Implementation of the sensor in various sulphide-rich marine environments (mangrove swamp, shallow waters sediments in the Baltic and deep-sea hydrothermal environments) is also planned.
The three year grant is to be started from Sept. 1, 2009. The position will be open until a candidate is retained. Enquiries and applications can be made to Dr Nadine Le Bris (lebris@obs-banyuls.fr).
