DIVEVOLK SeaLink Supports Southern Media Group​'s World Earth Day Coral Expedition Livestream

On Earth Day 2026, Southern Media Group live‑streamed a real‑time coral expedition off Sanmen Island, Zhuhai. Professor Liu Lan’s team from Sun Yat‑sen University conducted an annual coral survey in the Miaowan Coral Nature Reserve – and viewers watched the fieldwork as it happened underwater. The livestream showed a 50‑meter survey transect, coral health checks, and a surprising ecosystem: the turbid Pearl River Estuary actually feeds heterotrophic corals (soft corals and gorgonians). It turned marine science from a delayed report into a shared live observation. How SeaLink Enabled the Broadcast ? Underwater, standard wireless signals fail. DIVEVOLK SeaLink solves this. It is a self‑developed real‑time video transmission device that connects an underwater smartphone to a surface receiver via a WiFi‑based contact workflow. In this broadcast, a smartphone was placed inside a DIVEVOLK SeaTouch 4 Max housing (rated to 60m). SeaLink transmitted the phone’s video feed to the surface (live streaming range up to 30m). The feed was then routed directly into Southern Daily’s professional production system – no post‑dive delay, no special underwater broadcast camera required. Key technical points: 1. SeaLink supports live underwater video transmission up to 30 meters (the housing itself is rated to 60m for recording/photography). 2. It works with any smartphone inside a compatible DIVEVOLK housing, keeping full touchscreen control. 3. The output is a standard video feed that can enter professional switchers, encoders, or streaming software. Why This Matters ? Real‑time underwater video opens new possibilities: coral monitoring, remote expert consultation, marine protected area broadcasts, education programs, and public science engagement. Live fieldwork is more transparent and easier to understand than edited highlights. DIVEVOLK SeaLink was designed so underwater imagery no longer stays only on a diver’s memory card. This Zhuhai expedition proved the model: compact, affordable, and production‑ready. 🌊 Learn more: www.divevolkdiving.com
