Opis zadań:

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 OPUS-26, no. 2023/51/B/ST10/01344) and awarded to professor Piotr Kowalczuk. The research project in the framework of OPUS program is entitled “Optical proxies of essential biogeochemical variables and their application in the accuracy assessment of satellite ocean color remote sensing in the North-eastern Greenland shelf”. This project will be conducted with collaboration with Norwegian Polar Institute, Fram Centre, Tromsø, Norway, National Institute of Aquatic Resources, Technical University of Denmark, Kgs. Lyngby , Denmark, and University of Amsterdam, Faculty of Science.
PROJECT DESCRIPTION:
Rapid warming over the last decades had led to the reduction of Arctic Ocean sea ice area and thickness, which led to increased primary production and changes in phytoplankton community structure toward smaller organisms. The main goal of the project is to determine set of empirical relationships between selected essential biogeochemical variables and inherent/apparent optical properties in the East Greenland shelf, and in the Fram Straiy which is dominated by the Polar Water. We hypothesize that the changes in the energetic level and spectral composition of the natural light field in the Arctic Ocean will change with rising water temperature and associated decrease of perennial sea ice area and thickness. This will lead to an increased amount of solar energy reaching the Arctic Ocean surface and its deposition in the mixed layer as heat. Changes in phytoplankton community structure towards smaller organisms is associated with changes in phytoplankton bio-optical properties as smaller organisms usually absorb solar energy more efficiently. The spectral quality and underwater irradiance intensity in the Arctic Ocean is further modulated by specific inherent optical properties in different water masses. In the proposed research, we aim to address the question of how the distribution of inherent optical properties (IOPs) in both horizontal and vertical scales in distinct bio-optical provinces in the Arctic Ocean impacts the underwater field structure, as well as the return flux of upwelling radiance that could be detected by satellite sensors. We will quantify and determine the relationships between optical properties and essential biogeochemical variables, such as the concentrations of chlorophyll-a, nitrates, particulate and dissolved organic carbon in the study area. Developed relationships between IOPs and selected biogeochemical variables will be used to parametrize the radiative transfer model, which will be used for forward and inverse modelling. The former will be run for the estimation of apparent optical properties (AOPs) based on measured IOPs and the ones derived from biogeochemical variables, whereas the latter will be used for the development of regionally optimized semi-analytical ocean color remote sensing algorithms that would provide us with information on IOPs and biogeochemical variables based on AOPs measured in situ and from satellites. The main goal of this project will be achieved through re-analysis of existing data sets of IOPs and AOPs during previous international projects, collection of new environmental data and laboratory analysis and statistical analysis of field and laboratory data. Field work will be undertaken in summer months of 2024, 2025 and 2026 onboard of Norwegian and Danish research ships. We will conduct instrumental in situ measurements of physical and chemical characteristics of water column vertical profiles of salinity, temperature, and IOPs including in situ DOM and chlorophyll-a fluorescence. Simultaneously, spectral distribution of incident solar radiation and upwelling radiance with depth will be measured by a multispectral C-OPS submersible profiling radiometer. The intensity of incident solar irradiance at sea level will measures with deck reference radiometer. Direct measurements of remote sensing reflectance, will be performed with us a small floating platform equipped with a hyperspectral radiometer. Radiometric data will be analyzed together with in situ measured and water samples IOP to develop regionally validated empirical OCRS algorithms for retrieval of concentrations of chlorophyll-a, IOPs and concentrations of optically significant seawater constituents and the phytoplankton community structure. Developed algorithms will be applied to satellite products from various satellite mission to generate time series maps essential biogeochemical variables in the Arctic Ocean. Water samples will be collected on sampling stations at fixed depths for analyses in land based laboratories at Institute of Oceanology, Polish Academy of Sciences and Danish Technical University, National Institute of Aquatic Resources. With this work we aim to contribute to a better mechanistic understanding of the consequences of global climate change, in particular warming and longer ice free periods on the cycling of carbon in the Arctic Ocean, which will be important for informing biogeochemical or carbon–climate feedback mode.
Research tasks at the post-doc position:
• participation in field work in the Arctic region, collection and preservation of samples,
• conducting measurements of inherent and apparent optical properties with use of in situ optical instruments during field work activities
• spectroscopic laboratory analysis: of chlorophyll-a, CDOM and particulate absorption and fluorescence measurements of dissolved organic matter,
• data analysis, running radiative transfer model, statistical analysis and modeling –, PCA model for spectroscopic, chromatographic, chemical, and environmental data,
• participation in development of empirical formulas for optical proxies of biogechemical variables and development of the regionally optimized ocean color remote sensing algorithm for estimation of selected inherent and apparent optical properties of Arctic Ocean waters
• 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
