Monitoring coastal dynamics through citizen science: COASTIE Canada
Description
Coastlines across Canada are increasingly susceptible to erosion, primarily driven by the impacts of climate change, such as the growing frequency and intensity of storms, and rising sea levels resulting from polar ice melt. In light of this issue the COASTIE Canada citizen science project was established in 2021, in collaboration with Parks Canada, and is based on the global CoastSnap program that originated in Australia in 2017.
Data is collected through photos submitted by citizen scientists at Coastie stands located within national parks across Canada. These stands are typically mounted on either a wooden post anchored in the ground or on existing boardwalk infrastructure. A small platform atop each stand holds an aperture for cameras, ensuring they remain fixed and aligned at a consistent angle relative to the shoreline. During site surveys prior to installation, ground control points (GCPs) are identified within the field of view of each station and surveyed with high-accuracy equipment. Once submitted, the images are georectified (converted into a top-down view) with a MATLAB script, using the GCPs as anchor points. This process enables precise mapping of shorelines regardless of conditions, offering valuable data on shoreline change.
Citizen science is an invaluable tool for studying the dynamics of coastal systems, particularly in monitoring erosion and shoreline change. It offers a low-cost and straightforward approach to obtaining high-quality, consistent imagery of shorelines over different seasons and years. Coastie currently has 40 stations installed, spanning 13 national parks across Canada. In 2024 alone, one site had more than 300 pictures submitted by citizen scientists, highlighting the success of community engagement in coastal research.
