Dr. Brent Else (University of Calgary, Department of Geography) and Dr. Lisa Miller (Institute of Ocean Sciences, Fisheries and Oceans Canada) are seeking a Postdoctoral Researcher to contribute to the international project: "Climate relevant interactions and feedbacks: the key role of sea ice and snow in the polar and global climate system (CRiceS)". The goal of this project, funded in part by the European Union’s Horizon 2020 programme and Canada’s New Frontiers in Research Horizon Global Platform, is to improve how biogeochemical models represent the role of polar processes and feedbacks in the global climate system. The Postdoctoral Fellow will work with both observationalists and numerical modellers within the CRiceS project to compile existing observational data implementation in model development. Specific efforts within CRiceS include better understanding of: air-sea exchange in the presence of sea ice; carbon export and deep sequestration; iron and nutrient supplies to sea-ice biota; and seasonality and sources of aerosol precursors; among other topics. The PDF should expect to conduct field studies relevant to the requirements of the modeling efforts. The ideal candidate will be either an observational scientist interested in pathways to mobilize field studies in climate models, or a modeling scientist interested in broadening their perspectives to include observational Polar science. Specific experience in any of the following fields will be considered, with experience relevant to polar seas preferred, but not necessary: Marine biogeochemistry Air-sea gas exchange Carbon cycling in the Earth system The Fellow will join a dynamic research group that conducts world-class research on Arctic marine biogeochemistry, while also supporting Inuit capacity for environmental monitoring and response to climate change. Extensive access to the Arctic will be available through existing grants held by Dr. Else and through collaborations with government departments and other Canadian and international universities. In particular, the position involves strong collaboration with the Institute of Ocean Sciences, Fisheries and Oceans Canada’s oceanographic research facility in Victoria, British Columbia and a leading institution of ocean climate research. The Fellow will have access to logistical support and instruments necessary for marine and atmospheric research in the Canadian Arctic.
