On June 8, 2026, Guangdong Radio and Television(GRT )used DIVEVOLK SeaLink during Guangdong's "Meet the Sea, Protect the Ecology" ocean-science panoramic livestream from the Wanshan Islands. The broadcast was part of China's World Oceans Day and National Ocean Publicity Day programming, but the most important detail for DIVEVOLK was practical: a local television team brought live underwater explanation into a public broadcast, an expert-led science program and an island classroom in real time.
For readers outside China, this deserves a little context. Zhuhai is a coastal city on the western side of the Guangdong-Hong Kong-Macao Greater Bay Area, the region that links Guangdong Province with Hong Kong and Macau. The Wanshan Archipelago, including islands such as Guishan, Wailingding, Dong'ao and Miaowan, sits in the Pearl River Estuary, where island communities, fisheries, tourism, marine research and conservation work all meet in the same sea area.
That setting is exactly why the livestream mattered. Ocean protection can feel abstract when it is reduced to policy language or edited footage. By using DIVEVOLK SeaLink in the Wanshan underwater livestream workflow, Guangdong Radio and Television(GRT) helped turn the sea into a live classroom: viewers could see the underwater scene while divers, hosts and experts explained what was happening.
The English recap video is now available on YouTube, showing how SeaLink helped connect the underwater scene with live commentary and surface-side viewing.
What Happened in Wanshan on World Oceans Day
The June 8 livestream followed the launch of Zhuhai's World Oceans Day and National Ocean Publicity Day activities on June 6. The program brought together Zhuhai's ocean-development authorities, marine research institutions, media teams and public education partners. Local reports described it as Guangdong's first high-definition underwater science explanation from the Wanshan sea area.
The livestream used a "1+N" panoramic format, with Wanshan as the core filming location and multiple education scenes connected around it. Hosts and experts visited Guishan Island to explain how island protection, tourism, community life and marine restoration can be balanced. Drone footage, surface images and underwater cameras worked together to show coastlines, wetlands, restored marine habitats and underwater biodiversity from several angles.
DIVEVOLK's project materials confirm that Guangdong Radio and Television(GRT) used SeaLink as part of this underwater livestream workflow. That made the SeaLink use case different from an ordinary product demonstration. It served a public communication goal: helping people understand the underwater environment while the explanation was happening, not after the dive had already ended.
For DIVEVOLK, that framing is familiar. Good underwater imaging is not only about making beautiful pictures. In conservation and education contexts, an underwater phone housing, dive lights, lenses and a real-time transmission layer can help turn a dive into documentation, evidence, teaching and public engagement.
Why SeaLink Mattered to Zhuhai TV's Broadcast Workflow
Water blocks conventional wireless signals, so a smartphone that works normally on land usually loses stable connectivity once it is submerged. The DIVEVOLK SeaLink underwater transmitter is designed to solve that problem for supported workflows by carrying a smartphone's underwater video signal toward the surface, where the feed can enter a livestream, a classroom display or a professional media workflow.
In the Wanshan program, that connection helped the broadcast move beyond "we filmed something underwater." A surface team could follow the underwater scene, hosts and experts could explain what viewers were seeing, and the program could treat the ocean as a live subject rather than a silent background.
SeaLink currently supports underwater livestream signal transmission to 30 meters. The SeaTouch 4 Max underwater housing system that carries the smartphone is separately rated for underwater use to 60 meters. For live broadcast work, teams plan around the SeaLink transmission range; for still photography or recording beyond that, the housing depth rating is a separate specification.
That distinction matters for professional users. SeaLink is not a replacement for a production plan, diver training or site safety. It is the communication layer that allows an underwater phone-based imaging system to become part of a live surface-side workflow.
The Classroom Signal: Why Guishan Primary School Matters
One of the strongest details in the Wanshan livestream was the school connection. The live signal was set to enter a classroom at Guishan Primary School, where Peng Yalan, a senior engineer from the Ministry of Natural Resources' Zhuhai Marine Center, would guide children through the underwater world. SSI instructor trainer and Macau International Ocean Diving Association vice president Zhang Kai was listed as the diver conducting underwater explanation.
In Chinese public communication, "science popularization" does not mean simplifying science until it loses meaning. At its best, it means making expert knowledge accessible to families, students and ordinary viewers. A live underwater feed helps that happen because the audience can follow the observation process. Coral protection, marine debris, biodiversity and responsible diving become visible, not just described.
For a child in a classroom, the difference is enormous. The ocean is no longer a blue area on a map or a paragraph in a textbook. It becomes a habitat with organisms, work methods, risks and responsibilities - and it is happening close to home.
Why Wanshan Is a Useful Place to Explain Marine Conservation
Wanshan is not a remote tropical resort marketed only for postcard water. It is a working island region inside one of the world's most economically active coastal zones. Zhuhai is also known for its large sea area and many islands, which makes the city a natural test case for how coastal development and marine protection can be explained to the public.
That is why Wanshan works as a communication setting. If ocean conservation can be explained here, it has to speak to residents, students, divers, tourists, researchers, officials and media audiences at the same time. The message cannot be only "the sea is beautiful." It also has to show why monitoring, cleanup, restoration, careful tourism and island community development belong in the same conversation.
For international readers, the closest comparison may be a coastal national-park story, an island community story and a public science broadcast happening at once. Wanshan combines all three, with the extra pressure of sitting beside one of China's most dynamic urban regions.
From Documentary to Live Ocean Classroom
Zhuhai's World Oceans Day programming also included the public debut of the pilot for Island Speaks to All Living Things, a 10-part 4K micro-documentary series developed by Guangdong Radio and Television's 4K Ultra HD Channel and the Publicity Department of the CPC Zhuhai Municipal Committee. The series was filmed across the Wanshan Islands and is designed to reveal local marine ecology through ultra-high-definition storytelling.
One episode, Coral Whispers, was scheduled for its complete premiere on June 8, leading viewers into the coral world below the surface. This pairing of formats is significant. A documentary can craft memory and emotion; a live underwater explanation can create immediacy and trust. Together, they give the public two ways to understand the same sea.
DIVEVOLK has seen this shift from another angle. In April 2026, DIVEVOLK SeaLink supported Southern Television's Greater Bay Area coral expedition livestream around Sanmen Island, also part of Zhuhai's Wanshan Archipelago. In that earlier project, SeaLink helped route an underwater smartphone video feed from a SeaTouch system into a professional broadcast workflow.
The Wanshan World Oceans Day livestream points in the same direction. Real-time underwater imagery is becoming a tool for conservation education, field science, island tourism, youth learning and public communication.
Why Real-Time Underwater Video Changes the Public Conversation
Underwater work is usually hidden by default. A diver descends, performs a survey, returns with images or notes, and only later can a teacher, journalist or viewer understand what happened. Real-time underwater video changes that sequence. The surface team can see what the diver sees. A host can ask questions while the subject is still in frame. A classroom can follow the observation process instead of only seeing the edited result.
For marine conservation, that kind of timing is powerful. Coral monitoring, ghost-net removal, biodiversity recording and responsible diving are all process-heavy activities. They become easier to trust when the public can see the method, not only the claim.
The technology layer does not replace good diving practice. In fact, it raises the standard. A real-time feed only helps if the team maintains buoyancy, avoids contact with coral and marine life, follows the site plan and keeps the safety margin clear. For brands like DIVEVOLK, the product goal is to make responsible underwater communication easier, not to turn conservation sites into uncontrolled content stages.
Paired with SeaTouch housings, dive lights and lenses and filters, SeaLink gives teams a lighter way to make underwater scenes visible to people who may never enter the water themselves.
CCTV Brought National Attention After the Local Broadcast
The Wanshan Islands also received national news attention during the same World Oceans Day window. CCTV-13's News Live Room reported on Zhuhai-Macau cooperation in marine ecological protection, including coral monitoring, diver-led underwater cleanup, beach protection and cross-border marine science education. CCTV-13's Morning News separately reported on young people returning to Guishan Island as local infrastructure, tourism and community life improve.
For readers outside China, CCTV-13 is China Central Television's dedicated news channel. When a local island conservation story appears there, it becomes part of a national conversation about how coastal regions protect marine ecosystems while still supporting island livelihoods. In this article, though, the technology story begins with the local broadcast: Guangdong Radio and Television(GRT) using SeaLink to make the underwater scene visible in real time.
What Divers Can Learn From Wanshan
The Wanshan story offers a useful lesson for divers and underwater creators outside China. Ocean conservation is no longer only a specialist report written after the field season. It is becoming a public-facing communication practice that includes live video, school programs, island communities and citizen attention.
For divers, that means every image carries more responsibility. If you document coral, keep distance and neutral buoyancy. If you share marine life footage, avoid behavior that normalizes touching, chasing, feeding or harassing animals. If you join cleanups or citizen-science activities, document the method clearly and avoid turning sensitive habitats into performance spaces.
DIVEVOLK's World Oceans Day guide for divers makes the same point from an action perspective: June 8 is useful only if it turns into year-round habits. The Wanshan livestream shows what that can look like at a regional scale: monitoring, cleanup, youth education, island revitalization and public storytelling reinforcing one another.
A Local Chinese Story With a Global Direction
Wanshan is a Chinese island story, but the direction is global. Coastal communities everywhere are trying to explain why marine protection matters before ecosystems are damaged beyond repair. The most persuasive stories increasingly come from the field: the diver documenting the reef, the child seeing coral for the first time through a live feed, the young island resident deciding there is a future at home, and the scientist explaining what the data means while the habitat is on screen.
That is the deeper reason DIVEVOLK follows stories like this. Underwater technology is most valuable when it shortens the distance between the ocean and the people who make decisions about it. Guangdong Radio and Television(GRT)'s Wanshan livestream showed a version of that future: more visible, more educational and more connected to the communities living beside the sea.
