Merging Innovation and Restoration to Protect Coral Reefs Worldwide
Samsung and Seatrees have joined forces to restore and safeguard one of the planet’s most threatened ecosystems: coral reefs.
Bringing together mobile innovation, marine science, and community action, the partnership aims to accelerate reef restoration in some of the world’s most biodiverse coastal regions. With Samsung’s advanced imaging and mobile technology, scientists and local conservationists can now monitor coral health more easily – in the field, with a handheld device.
By using a smartphone to capture 3D photogrammetry – a technique that stitches overlapping images into detailed 3D models of reefs – teams can track coral growth, biodiversity, and structural changes accurately and efficiently. This gives local communities a more accessible way to measure restoration progress – critical for responding to climate threats like warming oceans and other human-driven stressors.
In partnership with University of California San Diego and the Scripps Institution of Oceanography, the initiative is now active in Fiji, Indonesia, and the Florida Keys. Each site is equipped with Samsung Galaxy devices featuring Ocean Mode, a custom camera setting designed specifically for capturing high-quality imagery of coral reefs.
Through Coral in Focus, our new documentary film, we invite you to explore this collaboration in action and see how technology, science, and community are coming together to protect the ocean.
It’s a new chapter for coral – and a new approach to global conservation.
Coral in Focus
Dive into the heart of our work in Fiji with Coral in Focus, which follows the impassioned scientists, smartphone engineers, divers, and local leaders restoring coral reefs on the frontlines of climate change. Set in the vibrant waters off Viti Levu, and shot in Seoul and the U.S. as well, the film highlights efforts to plant thermally resilient corals and bring damaged reefs back to life.
The story captures the beauty and urgency of ocean restoration efforts, featuring Galaxy smartphones withOcean Mode. In these moments, you see how mobile technology is helping researchers and local conservationists monitor reef health and track restoration progress—before it’s too late.
Project Sites: Global Restoration in Action
Viti Levu, Fiji
This project focuses on restoringshallow water reefs off Viti Levu. Here, 6,000 branching corals are grown in ocean nurseries for up to a year before being transplanted onto bare patches of coral reef within a locally managed marine area (LMMA). The outplanting mirrors the reef’s natural contours for better integration and uses thermally tolerant corals - species that survived past bleaching - to build long-term resilience against rising sea temperatures.
Highlights:
- 6,000 coral fragments grown and outplanted
- Organic cluster shapes designed to fit reef contour
- Uses heat-resistant coral species to enhance resilience
- Predator control through the removal of the Crown of Thorns Starfish
- One-year nursery phase before transplantation
Project Partner: Reef Explorer
Nusa Penida, Bali
We’re working with Ocean Gardener to restore reefs in both shallow lagoons and deeper, cooler waters off Nusa Penida. The team is planting 5,000 hard and soft coral fragments onto degraded reefs using an innovative “community cluster” method. Baby corals are arranged in a checkerboard pattern to boost survival and cohesion. Local teams maintain the site to protect young corals from threats like predators, sedimentation, and algal overgrowth. This location is uniquely positioned to grow thermally resilient corals in varying depths, offering added protection from warming seas and bleaching.
Highlights:
- 5,000 corals planted in a shallow lagoon and in water over 10 meters deep
- Checkerboard “community clusters” promote group survival
- Regular monitoring and removal of predators and sediment
- Focus on natural resilience to rising ocean temperatures
Project Partner: Ocean Gardener
Florida Keys, US
This project pioneers micro-fragmentation – cutting small pieces from slow-growing mound (or boulder) corals and placing them close together on coral plugs, where they rapidly fuse into a single colony. The corals are raised in land-based tanks for a year, protected from pests and bleaching, then replanted onto degraded reef structures. This method accelerates growth and allows for consistent monitoring and innovation in coral propagation.
Highlights:
- 3,000 mound corals grown using micro-fragmentation
- Raised in controlled, land-based saltwater tank
- Replanted after one year onto reef sites
- Enables faster growth of slow-growing coral species
Project Partner: Plant a Million Corals
Year 1 Impact Metrics
What is 3D Photogrammetry?
3D photogrammetry uses advanced imaging, often via Samsung Galaxy smartphones, to create detailed three-dimensional models of coral reefs. Divers take hundreds of overlapping photographs from different angles, which are stitched together using specialized software. In Seatrees' projects, especially in places like Fiji, 3D photogrammetry is used to:
- Monitor coral growth over time with precision.
- Track biodiversity improvements and structural changes in the reef.
- Assess reef health after storms or restoration interventions.
- Give scientists and local restoration teams a visual tool to measure and communicate progress.
By combining this technology with hands-on coral planting and community-based conservation, Seatrees and partners can scale restoration efforts more effectively, and transparently, while empowering local teams to lead long-term reef recovery.
Ocean Mode
Samsung Galaxy smartphones equipped with custom “Ocean Mode” and the Oasis app (developed at UC San Diego) are enabling local teams to capture high-quality underwater imagery - once only possible with costly, specialized equipment.
This imaging breakthrough:
- Makes coral monitoring more accessible and affordable
- Helps teams track coral growth and reef health over time
- Provides compelling visuals to engage and inform the public
- Supports data sharing between communities and scientists
Explore the reef and see restoration progress firsthand.
A Broader Commitment to the Ocean
This initiative builds on Samsung’s ongoing work to reduce ocean plastic and protect marine ecosystems. Since 2022, the company has repurposed more than 150 tons of discarded fishing nets into Galaxy device components. Now, through its partnership with Seatrees, Samsung is turning its technology into a tool for restoration, offering communities and researchers a low-cost, scalable way to protect coral reefs.
