BASc, MSc, PhD
Research:
My research focused on the detailed investigation of the light field in the water column with the purpose of enhancing our understanding of the interaction between electromagnetic radiation and ocean water constituents. These constituents included: photosynthetic pigments, inorganic suspended matter, and chromophoric dissolved organic matter. The Strait of Georgia, British Columbia, Canada was chosen as the study area due to its proximity, oceanographic complexity and lack of similar studies. This research provided new scientific data on the optical oceanographic characteristics of the area under the influence of the Fraser River plume.

Research:
The focus of my research was a temporal and spatial analysis of chl in the Strait of Georgia. To perform this analysis, imagery from MODIS was employed. An intermediate step included producing a set of algorithms adapted specifically to the conditions in the coastal waters of the SoG. This allows a better understanding of relationships, triggers, and constraints in both space and time between chl and suspended sediment concentrations. Identifying these temporal and spatial properties is important in a more complete understanding of the ecosystem in the SoG.
PhD Geography
Research Areas:
I am currently a post-doctoral fellow at the Remote Sensing Division of the National Institute for Space Research (INPE) in Brazil. My research interests lie on the use of Geomatics to study and model spatial and temporal ecological processes on wetland environments, at the landscape and ecosystem levels. I am especially interested in understanding and predicting the effects of climatic and environmental change on wetland vegetation ecology and biogeochemistry
Thesis Project:
My thesis research focused on assessing the contribution of aquatic plants (macrophytes) to the carbon balance of the Amazon floodplain, and its susceptibility to climate change. The amazonian macrophytes are associated with the highest methane emission rates in the floodplain, and also exhibit the highest degree of variability both in space (distibution) and time (productivity), thus representing one of the primary sources of uncertainty in current carbon cycle models for flooded Amazon ecosystems.

Laurie's thesis project evaluated the use of remote sensing to retrieve the optical and geochemical properties of inland and coastal waters. Traditionally, water quality sampling involves in-situ measurements as well as the collection of water samples for subsequent laboratory analysis. These methods are time intensive and expensive and do not provide a spatial or temporal view of water quality. The use of remote sensing provides the potential for less expensive analysis of water quality and allows an evaluation of the spatial and temporal distribution of water components using aircraft-based and/or satellite-based sensors
MSc Geography
Optical remote detection of surface water quality for open ocean waters has been ongoing since the 1960’s. This method of detection is much more challenging and not yet standard practice for the more optically complex inland and coastal waters. My research project dealt with the investigation of the potential application of airborne hyperspectral sensors to detect water quality in the Cowichan watershed, on Vancouver Island, BC. Lake Cowichan and Cowichan Bay, both apart of the watershed, have been examined as the inlands and coastal water bodies, respectively.
