Dear colleagues,
<p style="line-height: 100%; margin-bottom: 0in">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<sup>th</sup> April 2022. A
second related
position focusing on remote sensing using drones will be announced
shortly.
</p>
<p style="line-height: 100%; margin-bottom: 0in"><b>Project
description</b></p>
<p style="line-height: 100%; margin-bottom: 0in">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!</p>
<p style="line-height: 100%; margin-bottom: 0in">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.</p>
<p style="line-height: 100%; margin-bottom: 0in">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.</p>
