My previous experience includes the development, implementation, and optimization of machine learning-based algorithms for processing remote sensing images to extract useful information through image segmentation, classification, and change detection. I have also been involved in the development, implementation, and optimization of algorithms for satellite systems. My previous research has mainly focused on synthetic aperture radar (SAR) satellites and SAR image processing.

Currently, as a postdoctoral fellow in the SPECTRAL lab, co-supervised by Dr. Maycira Costa (Department of Geography) and Dr. Neil Ernst (Department of Computer Science), I am focused on developing machine learning methods for kelp mapping. In partnership with VERTEX Resource Group and the Hakai Institute, I am working on creating software that leverages deep learning approaches to determine the aerial extent of floating kelp using optical satellite images. The software, called Satellite-based Kelp Mapping (SKeMa), will be primarily used by the First Nations in British Columbia to monitor kelp in their marine Traditional Territories.

In line with the Space Strategy for Canada and Canada's Strategy for Satellite Earth Observation, this project aims to use Space-Based Earth Observation (SBEO) satellite images to aid First Nations in monitoring critical kelp ecosystems impacted by climate change. The active participation of the First Nations in the software development process will be crucial to ensure the final software is as user-friendly as possible. The developed framework will significantly enhance the use of SBEO imagery by the First Nations, enabling them to monitor essential habitats for Pacific salmon, a species of ecological, cultural, and economic significance in British Columbia. Furthermore, it will help identify key conservation areas, potential sites for kelp restoration, and planning for wild kelp harvest and aquaculture, contributing to the Blue Economy.

This project integrates interdisciplinary knowledge in ocean science, remote sensing, machine learning, community engagement, resource management, and SBEO industry experience. These elements collectively support SBEO capacity development, addressing the needs of Canada's space-related and technology sector.

I have a background in oceanography, climate science, and coastal ecosystems. My PhD project — a collaboration between UBC’s Changing Oceans Research Unit, UVic’s Spectral Remote Sensing Laboratory, and Ocean Wise — investigates the potential for kelp seaforestation in British Columbia under climate change. This includes assessing the vulnerability of British Columbia’s kelp habitat to climatic hazards and predicting where kelp could thrive in the future under various climate conditions along the coastline. I employ predictive models and scenarios for my investigations to enhance the public understanding of how restoring kelp can address critical issues such as climate change, biodiversity conservation, and food security.

In my free time, I enjoy exploring British Columbia’s unique landscape. I thrive in outdoor activities, whether in the water, on the water, or by the water. When I need some alone time, I head to the mountains to go climbing or backpacking.

Hi! My name is Jordanna and I'm a Canadian-American aquatic ecologist and conservation scientist. My love for the outdoors fueled a passion to learn how to take care of our beautiful world, and encouraged my desire to pursue a career in environmental research. 

For my postdoc, I have the privilege of working with Drs. Maycira Costa and Anne Salomon to evaluate the spatial-temporal dynamics of kelp-encrusting bryozoans ("KEB") across British Columbia's coast. In close collaboration with Indigenous, government, and research partners spanning from Haida Gwaii to Victoria, we seek to evaluate the abiotic and biotic variables that may be influencing KEB presence, abundance, and distribution within kelp forests. Encrustation by bryozoans may not only affect kelp forest health and resilience, but could also influence the diverse ecological communities they support. By weaving together ecological theory and Indigenous Knowledge to better understand how kelp forests tolerate and recover from KEB, amid phenological shifts due to climate extremes, we hope to illuminate their current and future health, and persistence.

I have a background in physical oceanography and remote sensing. I am particularly interested in the relationships between seawater properties and biological and physical processes in the ocean, which I observe using various satellite sensors. I have used optical imagery to analyze ocean colour and phytoplankton composition, as well as active microwave sensors to describe the sea surface and identify oil spills. My PhD research focused on the near-surface cyanobacteria blooms in the Baltic Sea, and characterizing their impact not only on the ocean colour, but also on the sea surface temperature and roughness observed with several types of satellite sensors.

During my postdoctoral research, I will apply my knowledge to map kelp beds with optical and SAR imagery (Synthetic Aperture Radar). Such a synergistic approach will provide more frequent information on the kelp bed extent since the SAR measurements are less sensitive to clouds. More detailed information on the seasonal kelp bed changes will help characterize their biomass fluctuations better and detect the alerting trends.

Aidan Wright is a Master’s candidate who will be mapping the spatial and temporal distribution of kelp-encrusting bryozoans on the BC coast. Kelp-encrusting bryozoans are very small, parasitic, invertebrate colonies that live on the surfaces of aquatic plants. Bryozoans can completely cover the surfaces of bull kelp and break them apart. Due to the ecological, sociological, and economic importance of kelp, these bryozoans are of great interest to researchers. Aidan will be using remote sensing data to distinguish between kelp with and without bryozoans, and create a methodology for identifying environmental clusters more significantly affected.

I am a marine ecologist interested in the relationship between the environment and species distribution and dynamics. I aim to understand how environmental conditions affect the species at different levels of biological organization and spatial scales. That is, how environmental conditions affect the species' individuals by conditioning their performance on diverse physiological processes such as growth and reproduction, as well as how such environmental conditions affect population-level processes such as recruitment and mortality rate. The same environmental conditions could affect at different levels of organization in a contrary way, making complex patterns emerge. In order to understand such complex relationships, I integrate diverse sources of observation (such as aerial images and field sampling) and experimental data into correlative and mechanistic models. They allow me to reproduce the observed distribution and dynamic of species and infer the potential effects of particular environmental conditions such as the high temperatures during heat-wave events. 

Currently, during my postdoctoral research, I work with the First Nations of the Broughton Aquiculture Transition Initiative (BATI), the Spectral lab, the Kelp Rescue Initiative, and the Salmon Coast Field Station (SCFS). Our goal is to improve our knowledge about the distribution and state of kelp in the Broughton area (northeast of Vancouver Island) and how it could help in the recovery of wild salmon populations in the area by giving them better habitat conditions. My specific objectives in the project are to perform field observations and species distribution model predictions to map the distribution of bull kelp in the Broughton area. Furthermore, I will calibrate a Dynamic Energy Budget model for the bull kelp, Nereocystis luetkeana, to identify the main drivers of its temporal changes and the physiologic processes involved. Finally, I will participate in assessing the use of kelp habitat for juvenile salmon for evidencing the potential importance of kelp for salmon population recovery in the area.

Lauren Man is a Master’s candidate with interests in using novel technologies to enhance ecosystem monitoring efforts, particularly in kelp forests. Kelp forests are extremely productive and diverse ecosystems that support a huge variety of marine creatures and provide a myriad of ecosystem services to coastal communities. Lauren’s project is focused on characterizing the spatial and temporal resilience and identifying the drivers of change of kelp forests in the territories of three of the Kwakwakawakw’ Nations: the ‘Namgis, Mamalilikulla and the Kwikwasut’lnuxw Haxwa’mis First Nations, in what is now known as the Broughton Archipelago of British Columbia, Canada. In this region, kelp forests are important habitat for juvenile salmon, and conserving kelp forests is a vital part of a larger effort to bring back healthy wild salmon runs in an area of sea lice and virus epidemics caused by salmon farming industries. This project is a collaboration between the SPECTRAL remote sensing laboratory and the Broughton Aquaculture Transition Initiative (BATI) and will help improve the management of kelp ecosystems in the Broughton area.

Lauren is from Hong Kong and has a BSc in Marine Biology from the University of California, Los Angeles. Throughout their undergraduate degree, they primarily conducted research on the spatial and temporal dynamics of environmental DNA (eDNA) in the kelp forest ecosystems of Southern California, aiming to improve the utility of eDNA as a biomonitoring method of kelp forest ecosystems. She also researched threat discrimination in skinks on the island of Moorea, French Polynesia and oyster ecophysiology in the face of changing climatic conditions in Hong Kong. Aside from research, they also love snapping pictures on their camera and have worked as a photographer for an environmental education centre, a newspaper, and a recreation centre. She also loves to climb rocks, snorkel, and enjoy what the planet has to offer.

Post Doctoral Researcher

Nasiha is an optical oceanographer, carrying out research in satellite remote sensing analysis of coastal, estuarine and open ocean waters. Earlier research modules during her Ph.D. work were involved in biogeochemical characteristics of oceanic waters by the use of remotely sensed satellite imagery. Nasiha had developed several in situ observation-based ocean optical models and their proof-of-concept algorithms for remote sensing implications, to better understand the oceanographic particle system spanning from sediment settling velocity to particulate load composition. Nasiha engaged in a number of ocean research cruises for the field measurement of optical-oceanographic parameters such as radiometric quantities, coefficients of absorption, attenuation, scattering and fluorescence, turbidity together with aerosol optical thickness of the atmospheric column.

Presently, Nasiha is working in the FOCOS (Ferry Ocean Colour Observation Systems) research project that acquires and utilizes autonomous above-water radiometric measurements, primarily for the satellite remote sensing applications of marginal seas and dynamic coastal waters. Her recent study depicted the spatial variability of in situ remote sensing reflectance to derive uncertainties associated with transitional water boundaries and optically complex coastal waters. The research work showed that the high spatial variability in remote sensing reflectance was predominantly associated with the spatial dynamics of the optical water constituents, thus limiting the use of these datasets as Fiducial Reference Measurements for the satellite validation process. Nasiha is currently working with a large hyperspectral FOCOS dataset for the robust evaluation of satellite retrieved and atmospherically corrected reflectance.

Nasiha is an independent researcher, yet a collaborative teammate. To further say about Nasiha, she believes in the collective knowledge acquired by humanity to date, and her favorite quote is by Isaac Newton, “If I have seen further it is by standing on the shoulders of Giants”.

My background is in geography and remote sensing. My PhD research was on the distribution and changes of the giant kelp forest ecosystem, with focus on the sub-Antarctic latitudes of South America. I developed kelp mapping techniques using Google Earth Engine and Sentinel-2 imagery, validated with UAV and underwater surveys. I also compared current and historical kelp distributions using nautical charts from the 19th century, and analysed their future trends through the frequency and intensity of marine heatwaves and marine cold-spells around southern Patagonia.

My current postdoctoral research is on the resilience of the kelp forests along the British Columbia coast. The aim of this project is to determine the long-term distribution patterns of kelp forests (giant and bull kelp), to define their spatial-temporal resilience to environmental and biotic drivers. This project also employs a large amount of datasets, from satellite imagery to nautical charts to define how kelp canopies are changing over time.

Outside of my work, I enjoy knitting and drawing. I’m also an amateur accordionist always willing to learn and play more songs.

Nicola Houtman is a Master’s candidate interested in mapping important forage fish species in the Strait of Georgia in order to learn about important areas for conservation for their endangered predators (Chinook and marbled murrelets). The ecology and distribution of many of British Columbia’s forage fish are undocumented due to limited fisheries targeting forage fish, the focus on species or stock specific management rather than ecosystem-based management, and the highly mobile or migratory life history of forage fish species. In particular, the distribution of pelagic (i.e. water column) foraging habitats of forage fish is virtually undocumented for Pacific sand lance (Ammodytes personatus), Northern anchovy (Engraulis mordax), and surf smelt (Hypomensus pretiosus).

The main research goal of this project is to map forage fish distributions in pelagic habitats in the Strait of Georgia. The project will be accomplished by:

1) Creating species distribution models that can predict the locations of Pacific sand lance, surf smelt, and Northern anchovy (three key forage species with little distribution data).

2) Developing a methodology for using remotely piloted aircrafts (RPAs, i.e. unmanned aerial vehicles or drones) to map schools of forage fish in the field, and identify species and school metrics (e.g., average fish size, school size). 

3) Visiting the areas predicted as high and low probability of fish presence by the models and using the RPA methodology I develop to ground-truth the models (i.e. try to find fish). 

This project is in collaboration with Project Watershed, Parks Canada, and the Department of Fisheries and Oceans.

Sejal Pramlall is a Master’s candidate with an interest in using satellite remote sensing tools to quantitatively analyze bio-physical oceanographic processes.

The main objectives of her MSc research is to

i) determine the long term spatio-temporal dynamics of phytoplankton phenology along the British Columbia and South East Alaskan coastal waters, with a particular focus on the Queen Charlotte Sound region,

ii) to determine the environmental drivers most strongly influencing phytoplankton dynamics, and lastly

iii) to quantitatively delineate regions with similar phenological indices into distinct ‘phenoregions’ along the migration route of juvenile salmon.

The outcome of this research can redefine some of what we know about seasonal cycles of phytoplankton over the past two decades, which could in turn provide valuable insight into trophic linkages between phytoplankton and juvenile salmon populations in this region. This study is a collaborative effort between the Spectral Remote Sensing Laboratory and the Hakai Institute, and contributes to the overarching MEOPAR and Canadian Space agency project: ‘Spatiotemporal dynamics of the coastal ocean biogeochemical domains of British Columbia and Southeast Alaska - following the migration route of juvenile salmon.’

I am a biological oceanographer and I obtained my PhD in Environmental Sciences at the University of Quebec in Rimouski (UQAR). I am interested in understanding phytoplankton dynamics and productivity in the coastal and open ocean. My research explores the importance of physical-biological interactions in the pelagic realm and how simultaneous changes in several environmental drivers are affecting marine ecosystems. Most of my work is involved in generating long-term time-series by combining satellite information, field measurements, and model-derived data.

My postdoctoral research with the Hakai Coastal Initiative aims at identifying, by using very high-resolution satellite data, coastal marine biogeochemical provinces of British Columbia and Southeast Alaska and their spatial-temporal dynamic. Defining a coastal marine bioregionalization at regional scales will enhance understanding of how organisms and food webs may respond to different biophysical conditions.
