We are one Blue Planet
Supporting our oceans through technology, travel and training.

What we believe in

always looking towards the future.
World ecosystem illustration.

Oceans and coral reefs are the backbone of a multitude of ecosystems and for human livelihood. We have already lost or severely damaged more than 50% of coral reefs worldwide.

Through technology and tourism, Reef Support empowers more people to discover the world of coral reefs, and take action to protect them.

Article: "With AI, a Colombian studies where to restore corals in the country"

Addressing the labor-intensive and outdated techniques of traditional coral health analysis, Angela Alegria, a Colombian marine biologist, harnesses the power of artificial intelligence on Providencia Island, as the selected participant for Reef Support's 3D photogrammetry project, funded by WWF Netherlands INNO-fonds to carry out R&D with Corales de Paz.

Paper: Superpixels to the Rescue (Runhaar, 2022)

With the support of the University of Amsterdam, our CTO Yohan Runhaar carried out research to explore advanced methods for coral classification and segmentation, addressing limitations in current approaches. By leveraging computer vision techniques, the study offers a pathway to enhance efficiency and precision in assessing coral reef health using innovative AI techniques.

MSc Thesis: 3D Photogrammetry Analysis (Baauw, 2022)

Marc Baauw conducted this research as part of his MSc studies in GIMA, a program offered by TU Delft, Wageningen University, Utrecht University, and the University of Twente. His aim was to gain insights into the differences between two rugosity calculation approaches using SFM-based photogrammetry.

SOA Hackathon in Sausalito, CA 2022

During the AI for Coral Bleaching Hackathon organized by the Sustainable Ocean Alliance, the Reef Support team used the k-means segmentation technique to detect live coral cover and coral bleaching extent. This was a critical step in creating an accurate AI model to predict coral bleaching events and identify healthy and unhealthy coral reefs.

More information on Collecting and Labelling Data

In this blog, we'll explore how you can contribute to the conservation of coral reefs and help advance marine research through Open Coral AI. With just a few simple steps, you can take part in a global effort to monitor and protect coral reefs, even if you're not a marine scientist or conservationist.

The 1st Reef Ranger in Lombok: Amba Stapert

Meeting in the Netherlands and seeing her determination to take part as a volunteer, Reef Support and IBF decided that Amba would become the "first reef ranger", where she would travel to Lombok for 2 months to develop reef monitoring techniques and to set the groundwork for a continued reef ranger program into the future.

Coral Lab Developments: Part II
