Satellite Monitoring - SHARC Tracking Initiative
In a presentation to the Bristol Underwater Photography Group, Peter de Maagt, an antenna specialist for the European Space Agency (ESA), discussed the challenges and solutions in using satellite tagging for marine conservation, particularly for shark species and marine litter tracking.
Challenges in Satellite Tagging
Satellite tags, deployed on sharks and used for marine litter tracking, face several challenges. Data transmission and tag durability are crucial issues as satellite tags must reliably transmit data through marine environments where water attenuates signals, and tags must endure harsh conditions over extended periods.
Spatial and temporal resolution is another challenge. Tracking fast-moving sharks and dispersed marine litter demands precise, high-frequency location data. However, satellite coverage and tag battery life limit how often and how accurately these data can be collected.
Cost and scale, species-specific attachment and behavior, data integration and interpretation also pose significant challenges.
Solutions for Satellite Tagging
ESA's technological capabilities offer potential solutions to these challenges. Advanced antenna design, integration with AI and satellite networks, multi-sensor approaches, collaborations, and open data platforms, and innovations in energy efficiency and miniaturization are some of the solutions presented or implied in de Maagt's context.
Advanced antenna design optimizes signal transmission and reception, overcoming ocean-related signal losses, extending tag battery life, and improving data quality. Integration with AI analytics enhances understanding of shark behavior and marine litter movement. Multi-source data blending improves monitoring accuracy, while collaborations and open data platforms enable wider access and synthesis of tracking information.
ESA's Impact on Marine Conservation
ESA's satellite tags have key properties such as smaller and lower weight, longer battery life, increased memory, and bi-directional communication with the satellite. These features facilitate data collection on sharks and marine litter, providing valuable insights for conservation efforts.
The chips used in ESA tags are not limited to sharks but are also deployed on various species such as falcons, seals, turtles, polar bears, and albatrosses. An innovative project using these chips involves attaching them to albatrosses to help track fishing vessels operating illegally in protected areas.
The protected area near Saba, as shown by a dashed line on the map, is a suitable habitat for sharks, and ESA's tags have played a role in studying this ecosystem.
The Future of Marine Conservation
The computer chip used in the ESA tags is now readily available from a Belgium-based company, and multiple projects supported by ESA aim to address the issues of marine litter. This provides hope for the future as we continue to combat issues such as shark finning, where an estimated 100,000,000 sharks have their fins amputated each year.
In summary, Peter de Maagt, through his antenna specialization at ESA, addresses the core challenges of signal transmission and tag performance in marine environments, facilitating advances in satellite tagging technology that support marine conservation efforts targeting sharks and marine litter tracking. These solutions lie in sophisticated antenna design, integration with AI analytics, multi-source data blending, and global collaborations enabled by satellite infrastructure.
