Whangaparāoa Coastal Algae Monitoring

Babbage utilised UAV technology to assist marine ecologists in mapping and monitoring coastal algae growth (benthic monitoring) along the Whangaparāoa coastline. High-resolution aerial imagery captured by drone enables precise mapping of algae coverage, allowing for long-term comparative analysis to track environmental changes over time.
Conducting UAV-based marine surveys presents several unique challenges, including
Managing sun glare and water reflection to ensure accurate imagery
Stitching images over indistinguishable ocean surfaces for seamless mapping
Operating UAVs for extended periods over water from a shore-based vantage point
The aerial data collected serves as a critical supplement to sea-based surveys conducted by ecologists aboard survey vessels. By integrating UAV imagery with on-the-water observations, Babbage enhances the accuracy, efficiency, and consistency of algae monitoring efforts.
Advantages of UAV-based monitoring
Non-intrusive data collection with minimal environmental disturbance
High-resolution and repeatable imagery for long-term trend analysis
Cost-effective and time-efficient compared to traditional boat-based surveys
Enhanced safety by reducing the need for prolonged vessel-based operations
This monitoring initiative provides critical ecological insights, supporting Watercare in understanding environmental trends, assessing coastal health, and making informed management decisions. By leveraging cutting-edge aerial mapping technology, Babbage continues to drive innovative, data-driven solutions for marine conservation.
