Berg, Aaron
Soil moisture is an important component of the global water and energy cycle and in biogeochemical cycling. Meteorological conditions such as the near surface air temperature, boundary layer mixing heights and precipitation have been shown to depend, in part, on the soil moisture state. Accurate and timely soil moisture information has numerous applications in agricultural prediction and assessment, weather and climate prediction and streamflow prediction. Together with my research group we explore issues in hydrology using remote sensing and hydrological models.
My current areas of research are associated with following research networks and projects, well qualified students with interests in any of these topics are invited to contact me about opportunities for research funding:
GEOG*1300 Introduction to the Biophysical Environment
GEOG*1350 Earth: Hazards and Global Change
GEOG*3420 Remote Sensing of the Environment
GEOG*3610 Environmental Hydrology
GEOG*4110 Environmental Systems Analysis
GEOG*4690 Geography Field Research
GEOG*4990 Independent Study in Geography*
GEOG*6090 Geographic Research Methods

*Over the past several years I have advised a number of students in independent studies (GEOG 4990). If students are looking for potential research opportunities I have a number of projects related to hydrology or remote sensing available.

I’m always happy to chat about research opportunities for students with interests in terrestrial hydrology and/or remote sensing. Positions are available for students at the PhD or MSc level. Several funded positions are typically available to students interested in the applied use of GIS and remote sensing for observation of soil moisture (both passive and active sensors), soil freeze thaw processes, and agricultural land management. All projects provide excellent opportunities for combining field work, laboratory and computer analysis. We have field sites in the arctic, within boreal forests, and in agricultural regions. Students with backgrounds in Physical Geography or Geomatics, Physical Sciences, Engineering or Computer Sciences are encouraged to contact me to discuss available projects and funding opportunities.
