Day 1 · 2025-10-26
Released after nesting at Qilianyu North Island
Hainan Normal University Turtle Team at Qilianyu North Island BC-XS-2401 Calibration & Attachment。Luna Released after nesting，Curved Carapace Length 98 cm，Adult Female。North Island is China's largest remaining green turtle nesting site，2020 Annual Records 100+ nests.
🌊
Day 23 · 2025-11-17
Westward crossing of Zhongsha waters
After leaving Qilianyu, Luna migrated westward at ~20 km/day — consistent with South China Sea green turtle migration corridors reported by Ng et al. (2018). Multi-frequency GNSS fix accuracy ±8 m.
⚠️
Day 78 · 2026-01-11
High-risk vessel zone alert off Vietnam
AI detected 8 active AIS vessels within 3 km. BC platform notified the Institute of Oceanography (IO-VAST, Nha Trang). Luna altered course within 14 hours.
🍽
Day 142 · 2026-03-16
Seagrass foraging off E. Hainan coast
Luna stayed 18 days at 19.8°N near Wenchang. Diving shifted from transit to foraging (1–4 m daytime short dives, 18–35 m night dives) — typical green-turtle behavior.
📍
Day 189 · Today
Return to Xisha North Island waters
Luna is currently near Beidao at 16.97°N, 112.32°E; battery 82%, all sensors nominal. AI forecasts continued activity in the Macclesfield–Xisha area over the next 7 days.

Chengdu Zhishen Technology Co., Ltd was founded on a simple premise: better data leads to better conservation.
Our story
In 2018, a group of marine biologists and hardware engineers realized that existing tracking technology was either too bulky, too expensive, or lacked the battery life needed for long-term marine studies.
We started with a focus on sea turtles, developing a lightweight, non-invasive tracker that could withstand the harsh ocean environment while transmitting reliable data for over a year.
Today, our technology is used by leading research institutions worldwide.
Our vision
A world where every endangered marine species is understood, monitored, and protected.
Our core values
The principles that guide our engineering and conservation efforts.
🌊
Conservation
Our primary goal is the protection and preservation of marine ecosystems and endangered species.
💡
Innovation
We continuously push the boundaries of tracking technology.
🔍
Transparency
We believe in open data sharing and collaborative research.
🤝
Collaboration
Working closely with marine biologists and conservation organizations worldwide.
