Dear colleagues,
We are seeking four highly motivated Postdoctoral Researchers to join a research team with focus on* ‘Integrating Terrestrial and Aquatic Carbon and Greenhouse Gas Fluxes from Plot to Regional Scales across the Swedish Boreal Landscape’.* I would appreciate your help with distributing this advertisement to potential candidates. *Project Overview:* This project will be carried out by a team of five postdoctoral fellows who will jointly explore and integrate terrestrial and aquatic fluxes of C and GHGs from plot to regional scales in the boreal region of Northern Sweden. In this project, the postdoc team will make use a unique set up that integrates the well-established SITES research infrastructure of the Degerö and Krycklan catchments with the ICOS-Degerö and ICOS-Svartberget flux stations (www.icos-sweden.se; www.slu.se/Krycklan) and Svartberget Experimental Forests ( www.slu.se/en/departments/field-based-forest-research/experimental-forests/vindeln-experimental-forests/), where research related to catchment hydrology, biogeochemistry and forestry has been carried out for several decades. These excellent research infrastructures include permanently employed and skilled technical staff, 8 eddy covariance (EC) sites, >500 forest inventory plots, 16 long-term monitored streams and high-resolution Lidar scans which altogether provide valuable data to estimate terrestrial and aquatic C fluxes across two typical boreal catchments. Combined with tall tower EC and atmospheric concentration records to support inverse modeling, this provides exceptional resources for investigating and linking boreal C and GHG dynamics and their underlying drivers spanning from the plot to the regional scale. Throughout the entire project, the postdoctoral fellows will closely collaborate in their research activities to create new knowledge by bridging the various spatial scales. Thus, this project offers ample possibilities for scientific interactions and career development. Within this project, *four* 2-year Postdoctoral Scholarships (tax-free stipends) are available to address the following specific Work Packages (WP): *WP1 ‘Ecosystem-scale GHG fluxes’ *focuses on exploring eddy covariance (EC) data from 4 mire and 3 forest sites that are within close vicinity, i.e. experiencing similar climatic conditions. This unique repeated ecosystem-scale set up allows for investigating and comparing the spatial variability in C and GHG fluxes and their primary controls within the major boreal ecosystem types. This network of eddy covariance stations includes the well-established ICOS-Degerö (>15 years of EC data) and ICOS-Svarberget stations, as well as a recently established infrastructure including 3 new mire sites. The successful candidate will be mainly responsible for processing and interpreting these eddy covariance data and for publishing findings in relevant high-rank scientific journals. *WP2 ‘Landscape-scale GHG fluxes’* focuses on exploring tall tower eddy covariance (EC) data of CO2, CH4 and H2O fluxes across a 68km2 forest catchment (ongoing since 2016). This works takes advantage of the ICOS-Svartberget tall tower infrastructure which provides additional data of atmospheric GHG concentration gradients along a 150m tower and all relevant meteorological and environmental variables. Combined with a stream monitoring network to quantify aquatic GHG fluxes, this allow quantifying and investigating the full C and GHG balances and their primary controls at the landscape scale for a typical managed forest catchment in boreal Sweden. The successful candidate will be mainly responsible for processing and interpreting these tall tower eddy covariance data and for publishing findings in relevant high-rank scientific journals. *WP3 Regional-scale GHG fluxes* aims at producing a top-down estimate of the regional GHG budgets of the boreal region of northern Sweden. Atmospheric CO2 and CH4 mixing ratio measurements will be used, in conjunction with high-resolution atmospheric transport models. Observations from the tall ICOS-Svartberget tower, as well as from similar sites in the Nordic region will be used. An additional opportunity is to make use of tall tower eddy covariance flux estimates to downscale the flux estimates at the landscape scale. The successful candidate will be mainly responsible for developing atmospheric transport model estimates using the tall tower concentration data and for publishing findings in relevant high-rank scientific journals. *WP4 ‘Aquatic Carbon Fluxes’* focuses on compiling existing organic C and GHG fluxes and budgets of streams and lakes within the boreal region of northern Sweden. The goal is to understand the relative importance of these aquatic fluxes to terrestrial budgets from the landscape to regional scales. This work will make use of the decadal records of stream and lake biogeochemistry data collected within the well-established Krycklan catchment (www.slu.se/Krycklan). The successful candidate will be mainly responsible for compiling and analyzing stream and lake organic C and GHG flux data and for publishing findings in relevant high-rank scientific journals. *Qualifications:* • The candidates must have a PhD awarded in the fields of environmental sciences, hydrology, meteorology, physical geography or any other closely related subject • Demonstrated experience with eddy covariance data and micrometeorological theory (WP1&2), hydrology and catchment biogeochemistry (WP4) including data processing and interpretation is required • The candidates must be able to independently conduct field work, which also requires a driver's license valid in Sweden. • The candidates must be fluent in English to be able to write, communicate and interact in an English-speaking environment. • The candidates must have documented experience in writing and publishing scientific articles • Experience in either one or more of the following is considered a merit: carbon cycle research in boreal landscapes (i.e. forests, peatlands and aquatic systems), EC flux measurements in complex terrain, flux footprint modelling, inverse modeling, as well as skills in GIS, logger programming and/or in the handling and processing of large data sets *Place of work*: The postdoc location is at the Forestry Faculty of the Swedish University of Agricultural Sciences (SLU), Department of Forest Ecology & Management, in Umeå, Sweden. *Starting date*: At the earliest convenience *To apply:* Please send a CV, publication list, PhD diploma, copies of up to three relevant publications and a motivation letter (max. 2 pages) outlining previous research, current research interests and other activities of relevance for the position.
