[ES_JOBS_NET] PhD position in ecology/physical geography with focus on Arctic terrestrial ecosystems (4-years)

[Matthias Siewert]

Dear colleagues,

We are looking for PhD candidates in a project on changes in Arctic 
terrestrial ecosystems. Please help to spread the announcement to 
potential candidates. The application deadline is the 25^th April 2022. 
A second related position focusing on remote sensing using drones will 
be announced shortly.

*Project description*

Our planet is getting warmer, the Arctic is getting greener, shrubs and 
trees are growing better and moving up-slope. We can observe these 
vegetation changes on the ground and in satellite imagery, but we still 
need a better understanding of the dynamic nature of these changes. You 
can bring some light into this!

This PhD position offers you the opportunity to research vegetation 
trends in the Arctic. We will investigate how the Arctic is getting 
greener, what factors may cause stability and what factors may cause 
rapid change. We will map vegetation using remote sensing data from UAVs 
(drones) and satellites, and do fieldwork in the Swedish mountains for 
ground-truthing of vegetation plots and soil samples. Furthermore, we 
want to investigate and develop conceptual, GIS and numerical models 
that can confirm and predict the patterns we see over time in the remote 
sensing imagery.

The position runs over four years and is based at Umeå University. At 
the Department of Ecology and Environmental Science we provide an active 
research environment on Arctic and boreal vegetation research with an 
extended group of 4 PIs and over 10 PhD students and Postdocs. The 
modeling activity will be in collaboration with the Integrated Science 
Lab (IceLab) at Umeå University. The supervisors will be Dr. Matthias 
Siewert and Professor Johan Olofsson.
