In Arctic tundra, snowpacks play a critical role in mediating energy exchanges and carbon fluxes between the land surface and the atmosphere. Thick snowpacks provide excellent insulation of upper soil layers from very cold winter air temperatures. This has the potential to reduce the depth to which soils freeze in winter, thus accentuating the impact of summertime thaw of upper soil layers and near surface permafrost. Conversely, thin snowpacks provide relatively low wintertime thermal insulation causing deeper soil freezing depths for longer periods of the year. The duration and depth of soil freezing and permafrost melt has a major influence on microbial activity, which in turn controls the potential for release of stored carbon. Snowpack thickness and thermal conductivity of snow has a major controlling influence on the insulative properties of Arctic tundra snowpacks. However, modelling spatial variability in snow depth over tundra is challenging and snow thermal conductivity is often not well represented in climate models.
In this studentship you will work closely with an international team of leading scientists in earth system modelling, including secondments at the University of Waterloo, Canada. You will benefit from expertise in Arctic snowpack field measurements and modelling where access to unique field data sets will allow you to test new modelling approaches and apply them at larger scales across the Arctic. Specifically, this project will use a combination of: 1) meteorological and snowpack data already collected from a pan-Arctic range of field sites, and 2) the Land Surface Model from the NCAR Community Earth System model to investigate application of optimal snow process representation on spatial patterns of soil temperatures and biogeochemical cycling. To deepen your modelling knowledge and scientific skills base, this studentship will provide opportunities for you to make your own seasonal snow measurements in the Canadian Arctic.
This project would suit candidates with numerate degrees and a broad background in any combination of meteorology, physical geography, ecology, geoscience, maths, physics or computational sciences. For more information, please contact Dr Nick Rutter ([email protected]
