💶 Rémunération proposée : €3800 – 4200 per month

📝 Description du poste : Faculty of Science, Ecology and GeneticsThe University of Oulu is a multidisciplinary, international research university, with about 3,600 employees who produce new knowledge based on high-standards research and provide research based education´s to build a more sustainable, smarter, and more humane world. The University of Oulu community has about 17,000 people in total. Our northern scientific community operates globally and creates conditions for the emergence of innovations.We are now looking fora Postdoctoral researcherwho will focus on Arctic Atmosphere-Cryosphere-Hydrosphere Interactions (ACHI) as part of the Digital Water Flagship program headquartered at the University of Oulu.This postdoctoral researcher will join an interdisciplinary research team carrying out ACHI research in Finland, Scandinavia, Greenland and across the Arctic. Our Arctic Basin-wide program uses a network of year-round international research stations and data collection capabilities, and icebreaker-based measurements during expeditions in the eastern, central and western Arctic. Our studies are complemented by an entire cast of ancillary measurements from other agencies such as the Finnish Meteorological Institute, ship-based ocean and atmospheric properties, remote sensing via NASA and ESA as well as stream, river and lake properties in small and large watersheds across the north.About the jobYou will be working within the specific research group of the UArctic Research Chair Professor Jeffrey Welker at UOulu (Arctic Ecology and Biogeochemistry research group leader) and under the umbrella of the Digital Waters Flagship arena. You will be focusing on ACHI studies using in part our extensive multi-year water vapor, ocean water, and precipitation isotope (18 O 2H, d-excess) data sets to resolve issues such as: * a) how do patterns in atmospheric moisture transport, extreme events, and combinations of sea ice conditions control the production of moisture, and the spatial and temporal distribution of freshwater (snow and rain) across the north?

b) what are the processes and interactions that control the evolution of snow pack properties across the Nordic region, W Europe and the entire north as they relate to freshwater resource delivery, and
c) how can the application of understanding the modern water isotope attributes be applied to climate proxy (i.e ice cores, tree & shrub ring, sediment cores) records of past climate interpretations that can then be applied to forecasting future water resource conditions.

These studies will leverage our existing collaborations across Finland, Scandinavia, Greenland and the USA as well as those with the Swedish Polar Research Secretariate (Oden icebreaker), the US Coast Guard (Healy icebreaker) and the US NSF (Sikuliaq icebreaker). You will have opportunities to devise new and creative ways in which to development state-of-the-art Digital Twins of ACHI including hind sight, real-time and forecasting of the Pan Arctic water isotope cycle visualizations. In addition, you will work towards delivering real-time data to local, regional and international scientific and managerial end users. You will also have opportunities to develop applications that involve AI, Machine Learning and tools that will allow decision support activities by end users. You will also collaborate and assist in UOulu´s doctoral education and research alongside other senior staff and professors. Some teaching instruction, such as in PhD course may also be possible.Who are you?We expect from you:

A PhD and prior postdoctoral experience in atmospheric, marine, sea/land ice, and or ecosystem stable isotope geochemistry, or related disciplines within the last 10 years. The PhD degree must be obtained before the start of the contract, but no more than 10 years ago.
Demonstrated effective writing skills through high-quality publications, as senior and co-author including some international experience and networking with colleagues within Scandinavia, North America and or W Europe. As well as, demonstrated oral communication skills as evidenced by oral and poster presentations at national and international meeting such as EGU and AGU and experience in providing guest lectures in university or college settings.
Demonstrated capability to work independently and in collaboration with colleagues across a range of Arctic earth and associated science disciplines.
You should have skills in big data management including large observational and/or modelling datasets and familiarity with data integration techniques and tools including numerous parameters and aspects of the water cycle. Such as working with synoptic weather data, sea ice and hydrologic data along with using machine learning and AI tools as well as coding experience in R, Python and related packages.
Experience with High-Performance Computing (HPC) environments, parallel computing and distributed systems are important capabilities for this position.
