Lianna Gendall is a Master’s candidate with interests in kelp forest ecology, ecosystem-based management and the use of remote sensing to answer important ecological questions. Kelp forests are some of the most diverse and productive habitats on earth and provide many important ecosystem services to humans. Lianna’s research is focused on creating a baseline map of kelp forest distributions along the coast of Haida Gwaii and exploring environmental drivers of change in these ecosystems. This project is a collaborative effort between the SPECTRAL remote sensing laboratory, the Hakai Institute and the Marine Plan Partnership for the North Pacific Coast (MaPP) and will help to improve management strategies for kelp forest ecosystems in the future.

Lianna has a Bachelor’s degree in Animal Biology from the University of Alberta. Throughout her degree, Lianna’s curiosity and love for the ocean grew while working as a research assistant and Dive Master on several international marine research bases.  She spent the last semester of her BSc. at Bamfield Marine Sciences Centre, where she fell in love with the complex and beautiful temperate ecosystems of the west coast of Canada.  Since graduating, she has worked as a coral reef ecology instructor in Mexico and with the Salmon Coded Wire Tag Laboratory of J.O. Thomas & Associated Ltd. All of these experiences have solidified her desire to identify and monitor long-term change in coastal marine ecosystems and she is excited for the new experiences and challenges that lie ahead.

Brian’s MSc was focused on quantifying uncertainties of kelp bed metrics associated with changes in tidal height and current, as detected by remote sensing. Brian used data from in situ hyperspectral radiometers, multispectral UAV, high-resolution WorldView imagery, and supplementary data acquired from established Hakai kelp monitoring sites near Calvert Island to complete his thesis.

I completed a PhD on Biological Oceanography, with main research interest on phytoplankton ecology and photo-physiology, primary production, ocean color and remote sensing of the ocean, coastal water bio-optics and riverine-coastal oceanography. The main focus of the current project is to combine high resolution satellite remote sensing with in situ oceanographic sampling to examine the spatial and temporal variability of the physical, chemical and biological properties of the coastal oceans from British Columbia to Southeast Alaska. The project aims to address what are the spatial and temporal dynamics of the biogeochemical properties of the coastal oceans of British Columbia and Southeast Alaska; what are the dominant bottom-up control processes driving the dynamics of these regions; and what are the implications of bottom-up processes for regional primary productivity, and the foraging habitat available to migrating juvenile salmon.

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.

In summer 2016, we acquired two satellite images covering Cowichan Bay and the Gulf Islands, at the same time that three groups of volunteers from Pender Island Conservancy, Mayne Island Conservancy, and Cowichan land trust led by Leanna Boyer from Sea Change mapped the exact location of kelp beds using kayaks and GPS. From this data we are able to ground truth what we define as kelp in the satellite images.

 

 

 

 

In the spring and summer of 2017, in situ surveys of kelp beds were conducted to understand how juvenile salmon from the Cowichan River use kelp bed habitats as they migrate north.

Snorkel survey and remote underwater video was used to compare the use of kelp beds to adjacent no kelp habitat.

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.
