Description

Hydrological controls on the carbon dynamics of boreal peatlands – Investigated at the Ust-Pojeg mire complex, Komi Republic, NW-Russia

Discipline: Geosciences, Chemistry, Biology

Outline:

Peatlands, which are mainly located in the northern high-latitudes, are globally important storages of freshwater and carbon. Will these sensitive ecosystems maintain their important functions as carbon sinks and water regulators under the on-going climate and land use change? To evaluate this question, we want to start an interdisciplinary cooperation project on the coupled water and carbon dynamics of boreal peatlands. We want to (1.) analyse the spatial and temporal dynamics of all water balance components of a typical boreal mire of Northwest-Russia, (2.) quantify the input, throughput and output of dissolved organic carbon (DOC) and dissolved inorganic carbon (DIC) of the mire, (3.) characterise the biogeochemical composition of DOC and DIC in inflow, peat pore and outflow waters and thus gain new insights into the processes that control the generation, transport and transformation of DOC and DIC in boreal peatlands, (4.) quantify the complete carbon balance of the investigated peatland by combining the results of the lateral carbon fluxes with measurements with the vertical land-atmosphere CO2 and CH4 fluxes determined by the eddy covariance approach, and (5.) compare the hydrological and biogeochemical measurement data with output from several regional hydrological models of different resolution and a wetland module of a dynamical earth system model, taking into account their different spatial scales.

Responsibilities:

The PhD candidate will focus his/her work on the quantification of the input, throughput and output of dissolved organic carbon (DOC) and dissolved inorganic carbon (DIC) of the mire, and the characterisation of the biogeochemical composition of DOC and DIC in inflow, peat pore and outflow waters (Topics 2 and 3 of the project described above). He/She will participate in the planning of extensive field campaigns to a remote area in the Komi Republic in Russia. Field work at the investigated peatland site in Russia of about 2-3 months per year will be expected. The PhD candidate will help to establish and maintain hydrological and micrometeorological field instrumentation at the investigation site, including automatic discharge and water level recorders, standard-meteorological sensors and an eddy covariance flux measurement system. The PhD candidate will be responsible for appropriate sampling of inflow, peat pore and outflow waters as well as for in-depth biogeochemical analyses of DOC and DIC in the laboratories of the Institute of Soil Science and the Institute of Biogeochemistry and Marine Chemistry. He/She will conduct the statistical analysis and interpretation of the data and is expected to publish the results in international peer-reviewed journals.

The work of the PhD candidate will be closely integrated in the research activities of the junior research groups “Regional Hydrology of Terrestrial Systems” led by Jun.-Prof. Dr. Lars Kutzbach and “Chemistry of Natural Aqueous Solutions” led by Prof. Dr. Jens Hartmann. Specifically, his/her work will be complemented by the research of a postdoctoral scientist who will be responsible for the hydrological measurements and modelling at the investigated peatland site in the Komi Republik and shall be hired soon, too.

Requirements:

The PhD candidate should have an academic degree in an academic subject area qualifying the holder to carry out the above-mentioned responsibilities, e.g. Geosciences, Chemistry, Biology. He/She should have experience with laboratory and field work as well as with statistical data analysis The candidate should be an excellent team-player and should be highly motivated for interdisciplinary work in an international environment including extensive field work in a remote area of Russia. He/She should have very good English skills; language skills in Russian would be a plus.

For additional information please contact Jun.-Prof. Dr. Lars Kutzbach (lars.kutzbach@zmaw.de).
