Project Status Completed

Data collection closed on 31 December 2025. No further observations are being accepted.
The dataset is now locked and preserved as a permanent scientific record of Pelagia noctiluca in Aegean.
Pelagia Logbook: Aegean Sea 2025 is a dynamic citizen science project by Merman Conservation Expeditions Ltd. in collaboration with BiodiversityGR. Our mission is to monitor, map, and understand the movements of the mauve stinger jellyfish (Pelagia noctiluca) across the Aegean Sea throughout 2025.
​
This project is open to everyone – divers, beachgoers, sailors, and scientists alike. Whether you're out for a swim or conducting marine research, your observations matter.
​📊 What We Offer

🔹 Live Map: An interactive heatmap of verified sightings based on GPS-tagged data.
🔹 Sightings Table: A searchable table showing location, date, and jellyfish abundance.
🔹 Trend Insights: Monthly summaries and bloom alerts.
🔹 Data Sources: Integrated reports from iNaturalist, Facebook groups, direct email, and our reporting forms.
🔹 Quality Control: Data are validated before publishing to ensure reliability.

🎯 Project Goals
​
  • 🌐 Raise public awareness about jellyfish seasonality and bloom conditions.
  • 🔬 Support scientific research into ecology and population dynamics of Pelagia noctiluca.
  • 🌱 Promote responsible marine stewardship through community participation.
  • 📈 Build long-term datasets for policy and conservation planning.
