Research Areas:
My broad interests are in zooplankton ecology and biological oceanography. For my PhD research, I determined how short-term variations in food quantity, food quality, and primary productivity influence zooplankton communities in coastal marine ecosystems on the west coast of Canada and in the tropical waters of Guanabara Bay, Brazil. The main goal of my postdoctoral work is to investigate the level of synchrony between phytoplankton and zooplankton phenology in the Salish Sea. Time-series data for phytoplankton will be derived from various sources (satellite imagery, buoy data, ferry data, citizen science data, and research cruise data) and then coupled with historical and present zooplankton data. By looking at long-term spatial data of phytoplankton and zooplankton, we can identify their response to different climate drivers (e.g. SST, wind) and global climatic indices. Ultimately, changes in the seasonal patterns of these lower trophic levels will provide insight into their influence on the growth, survival, and overall return strength of salmon populations in the region.

Research Areas: remote sensing, ocean colour, algorithm development, optical equipment, spatial analysis, ocean dynamics.

Research Projects:

Salish Sea:  My graduate research project looked at the spatio-temporal optical and biogeochemical dynamics of the Salish Sea on the west coast of Canada.  Using an optical classification method I sub-regionalized the optical properties of this coastal region and used this information to parameterize satellite chlorophyll-a models with improved accuracy.  My project focused on the MODIS-Aqua and Sentinel-3 ocean colour sensors.  This outcomes of my research were to provide more accurate remotely sensed Chlorophyll-a data for an ecosystem based approach to effectively monitor the health of the Salish Sea.   

Amazon:  In the fall of 2014 I had the opportunity to be a project coordinator and researcher on the Cruizeiro do Sul, Research Cruise in Belém, Brazil.  This project focused on understanding the optical dynamics of the Amazon River Plume as it migrates out into the tropical Atlantic.  Using similar optical instrumentation and methods developed in the Salish Sea this was a great opportunity to apply and test my research in a new oceanic environment.  

FOCOS:  Ferry Ocean Colour Observation Systems (Current Project).  I'm currently involved with a new project that builds on my research with two permanent ocean colour monitoring stations installed on two ships of opportunity.  Through various partnerships this project will see two fully automated radiometric ocean colour instruments installed on two BC Ferries, one of which is now in operation.  In conjunction with Ocean Networks Canada this project presents a unique opportunity to combine resources and provide valuable and accurate ocean colour data that will be used to better understand the health of our coastal ecosystem.  As lead project coordinator I'm responsible for the successful deployment of these new systems, which are the first of their kind to go into full time operation in Canada.

Research Areas:
Remote sensing, water quality, land cover changes, water management, optical modeling

Motivation and background:
Regarding the extreme importance of freshwater for human beings and for ecosystem balance, and the fact the such resource has been threaten by human activities such as deforestation, mining and wastewater loading, I’m interested in manage the freshwater resource using remote sensing and GIS techniques.I took my undergrad in Biology at University of São Paulo (Brazil) where I had the opportunity to be introduced to limnology concepts and study the impacts of coal mining in a southern Brazilian watershed. In 2007 I started a Master’s in Remote Sensing at National Space Research Institute (INPE-Brazil), supervised by Dr. Evlyn Novo, to establish a water spectral library used to classify the Amazon water types using hyperspectral satellite images. After a PhD degree at the Geography Department in University of Victoria I am taking a Post-Doctoral research at INPE looking at optical properties of cyanobacteria for monitoring algal blooms.

PhD Research: (Click here for download full PhD Dissertation)
The PhD project aimed to evaluate the impacts of small gold mining activities in a large Amazon watershed called Tapajós. This area has been mined for more than 30 years which result in high sediment load into the river and its affluents. Such impact has changed not only the water quality but also decreased the light available for photosynthesis, in other words increased the light attenuation. The light attenuation has severe consequences for aquatic ecosystems such as phytoplankton mass decreasing, fish community shift and so on.To evaluate the small gold mining impacts on Tapajós watershed, the project was split in three main objectives/activities:
 
1. Measuring and describing the underwater light field in both impacted and pristine rivers;
 
2. Mapping the water quality changes using satellite images (Landsat database) in multi-temporal analysis; 
 
3. Integrating physical, biological and social information into a GIS environment to understand the main aspects that have driven gold mining activities in that area.

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.

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

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.
