Lake and sea ice and their snow covers are major components of Earthâs cryosphere and act to strongly modify climatic and biological systems. Both ice types serve as an important habitat for micro-fauna and support macro-fauna and strongly modify the exchange of energy, gases, and momentum...

Assessing Ecosystem Productivity Through the Integration of Micrometeorology and Optical Remote Sensing
DownloadSpring 2020
The main goal of this thesis is to contribute to the growing body of scientific work by exploring mechanisms of ecosystem productivity through the integration of remote sensing and micrometeorological data. This was done throughout by (i) identifying the environmental mechanisms affecting...

Characterizing an in-situ fraction of Photosynthetic Active Radiation product for implementation in the validation of MODIS-derived fraction of Photosynthetic Active Radiation products using continuous-wavelet transforms
DownloadSpring 2020
The goal of this thesis is to address the need to improve forestry monitoring and satellite validation techniques to better contextualize the effects that human-induced climate change is having on tropical dry forests (TDFs). Climate change is expected to change regional and global precipitation...

Evaluating recent advances in active microwave remote sensing for Arctic sea ice monitoring
DownloadFall 2018
The objective of this research was to evaluate recent advances in active microwave remote sensing technologies in order to further refine the optimal radar parameters for sea ice monitoring in support of marine operations and climate research. To achieve this objective, data from recent active...

River runoff plays a very important role in the Arctic Ocean. The Arctic Ocean accounts for around 1% of the total world ocean volume, but receives around 11% of the worlds river runoff. In addition, the Arctic Ocean is a β ocean, where stratification is primarily determined by salinity as...

The Arctic and the North Atlantic Oceans are experiencing multiple stresses such as loss of sea ice, changing atmospheric patterns, increasing wind energy at the ocean surface and larger freshwater discharge to coastal regions. To address how the marine system may respond to these stresses I...

Numerical modelling of the Arctic and North Atlantic exchanges with NEMO: Focus on freshwater and dynamics
DownloadFall 2018
The Arctic is currently undergoing significant changes due to increasing anthropogenic greenhouse gases causing atmospheric warming. The impact of this warming is clearly visible in the Arctic: reduced sea-ice cover, enhanced land-ice melting, increased frequency of extreme weather, etc....

Spatial and temporal variations of the surface energy balance and ablation on the Belcher Glacier, Devon Island, Nunavut, Canada.
DownloadSpring 2011
In the summer of 2008 (June 2nd – September 19th) detailed measurements of meteorological conditions and glacier surface properties were conducted in the Belcher Glacier catchment (718 km2), Devon Island Ice Cap, Nunavut, Canada. These measurements were used to force and validate a distributed...

Studying structural changes in tropical forests is essential for understanding changes in ecosystem complexity. In this thesis, I studied changes in ecosystem structure using two different airborne Light Detection and Range (LiDAR) systems collected 16-years apart (the 2005 dry season and the...
