Beachgoers are being invited to become citizen scientists, armed with nothing more than a smartphone, to help track the ever-changing coastline. This initiative, known as CoastSnap, is a global project that aims to monitor the effects of coastal erosion, rising sea levels, and climate change. The focus is on Tyrella Beach in County Down, where a unique photo spot has been set up to capture the shifting sands.
The project is led by Melanie Biausque, a geomorphologist with Geological Survey Northern Ireland. She emphasizes the importance of understanding the current state of the coastline to predict future changes and implement effective protection measures. By engaging regular visitors, the project can gather valuable data on the beach's evolution.
Tyrella Beach was chosen for its ongoing restoration efforts by local volunteers. These volunteers have been planting marram grass, installing fencing, and creating signage to safeguard the beach's ecosystem. Biausque's interest in their work led to the realization that there was a lack of documentation on the beach's progress. This sparked the idea of CoastSnap, which aims to fill that gap.
The coastline is naturally dynamic, with waves, tides, currents, and wind constantly reshaping the sand and dunes. However, scientists are preparing for significant changes due to climate change, including rising sea levels and more frequent storms. To understand these future impacts, they need to study the present-day dynamics of the coastline.
CoastSnap's innovative approach involves taking photos from a fixed frame, ensuring consistency in the data collected. The steel cradle, designed to hold a phone horizontally, frames a specific area of the beach. Visitors can take photos from this position and upload them to the CoastSnap website, where they are stored anonymously. This simple process allows scientists to build a comprehensive database of the beach's changes over time.
The project's Northern Ireland branch is funded by the Department for the Economy, and more sites are expected to be equipped with photo cradles and signs. The process is described as 'easy-peasy', requiring only a phone. Visitors can capture the beach's unique features, such as coastal erosion or vegetation changes, and share their observations, though anonymity is maintained.
Biausque highlights the importance of citizen science in understanding the complex interactions between sand, waves, currents, and tides. By collecting data from regular visitors, the project can provide valuable insights into how the coastline adapts and evolves. This knowledge is crucial for developing strategies to live with and adapt to the changing environment.
In conclusion, CoastSnap is a powerful example of how technology and community engagement can contribute to scientific research. By involving beachgoers, the project not only gathers valuable data but also raises awareness about the importance of coastal conservation. As the coastline continues to transform, initiatives like CoastSnap offer a unique opportunity to study and protect our precious coastal environments.
