A Post-doc position is available in the Remote Sensing Laboratory at Institute of Oceanology Polish Academy of Sciences in Sopot Poland. Candidate will work in the frame research project funded by the National Science Center, Republic of Poland (project no. OPUS 2019/33/B/ST10/01232) and awarded to assistant professor Piotr Kowalczuk. The research project in the framework of OPUS program is entitled “Estimation of diffusion coefficient of dissolved organic matter from sediments to overlying waters through relationships between its optical and chromatographic characteristics and dissolved iron in Baltic Sea deeps” and is planned to last three years. This project will be conducted with collaboration with National Institute of Aquatic Resources, Technical University of Denmark, Kemitorvet, 2800 Kgs. Lyngby , Denmark.

The main goal of the project is to determine diffusion coefficient of identified DOM fraction from sediments pore waters into near bottom water, and to relate its magnitude to oceanographic conditions: (salinity, dissolved oxygen concentration, DO, pH and sediment type). The working hypothesis of this project is that, the DOM optical properties are correlated with dissolved iron concentration in sediments pore waters and overlying waters. Project goal will be achieved through qualitative and quantitative characterization of the dissolved organic matter – DOM in the Baltic Sea deep’s bottom sediments pore waters and overlaying near bottom water and water column in different oceanographic conditions with use of absorption and fluorescence spectroscopy and High Performance Size-Exclusion Chromatography and established correlation between optical characteristics of DOM and concentration of dissolved iron and dissolved organic carbon. Spectroscopic analysis will include measurements of light absorption by chromophoric dissolved organic matter - CDOM, and measurements of DOM fluorescence excitation emission matrix spectra – EEMs. Chromatographic analysis will enable separation of different molecular weight fractions of DOM, and after fractionation spectroscopic analysis will be applied to characterize material grouped into molecular weight classes. Data achieved from spectroscopic, chromatographic and environmental and laboratory measurements will be analyzed statistically, to identify which molecular weight and qualitative DOM fractions were most susceptible to migrate and in which direction across sediments/near bottom water interface. Comparison of DOM composition, based on optical and chromatographic signatures, in collected samples will enable understanding of DOM transformation processes during its early diagenesis. This project will be executed through the field and laboratory work campaigns undertaken by team of experienced researchers during research cruises on board of r/v Oceania to Bornholm Deep, Gdansk Deep and Gotland Deep in the Baltic Sea.

Research tasks at the post-doc position:

• limited participation in field work, collection and preservation of samples,

• laboratory analysis: and spectroscopic absorption and fluorescence measurements of dissolved organic matter,

• conducting chromatographic analysis of collected DOM samples with cooperation with professor Colin A. Stedmon from DTU Aqua, Lyngby, Copenhagen, Denmark,

• data analysis, statistical analysis and modeling – development of PARAFAC model for fluorescence data, PCA model for spectroscopic, chromatographic, chemical, and environmental data

• participation in external consultations with foreign cooperating researchers and institutions, preparation of figures, tables, and writing manuscripts of scientific papers, presentation of results at conferences,

• participation in project promotion and dissemination
