Shanghai Jiao Tong University announced successful deep-sea trials at 3,500 meters, including the SPIDER deployer and hybrid Digital Optical Module, for Phase I construction in the South China Sea.
The tests verified impact resistance, precision positioning, and underwater connectivity, while prototype modules achieved single-photon-level detection. Scientists also recovered environmental moorings deployed in April 2025, gathering continuous oceanographic data.
TRIDENT aims to explore cosmic ray origins and astrophysical phenomena by detecting high-energy neutrinos, supporting interdisciplinary research in particle physics, astronomy, and ocean engineering, and providing new insights through innovative deep-sea observation techniques.
