Expedition on the Saba Bank to Enhance Tiger Shark Protection
This August a team of researchers will spend a week on the Saba Bank investigating the life-cycle of tiger sharks. Researchers will investigate the migration routes, where and when tiger sharks breed so they can protect them better within the Dutch Caribbean’s Yarari Marine Mammal and Shark Sanctuary as well as beyond. In this expedition members from the Saba Conservation Foundation (SCF), Nature Foundation St. Maarten (NFSXM), St. Eustatius National Parks (STENAPA), STINAPA Bonaire, the Aruba National Parks Foundation (FPNA), the Dutch Caribbean Nature Alliance (DCNA) and World Wildlife Fund for Nature the Netherlands (WWF-NL) will participate.
In 2016, the Saba Conservation Foundation, Nature Foundation St. Maarten, and Sharks for Kids partnered together as part of DCNA’s Save our Sharks Project funded by the Dutch National Postcode Lottery. Since then, satellite tagging of tiger sharks has been conducted on the Saba Bank and around Sint Maarten. Through this research we now know that tiger sharks in Dutch waters travel throughout the Caribbean basin, with most of these tagged sharks being sexually mature females. During the upcoming expedition the researchers aim to not only tag and track more tiger sharks to further investigate the life cycle, but they will also measure if and how large the pups inside pregnant tiger sharks are. This will help to determine if the Saba Bank is in fact a breeding ground for tiger sharks, one of the main goals of the expedition.
The other objective is to see where these transboundary sharks migrate to in order to better understand the importance of the Yarari Marine Mammal and Shark Sanctuary and protect other geographical areas. The Yarari Sanctuary was established on September 1, 2015 and aims to protect marine mammals, sharks, and rays throughout the waters of Bonaire, Saba, and since September 2018, St. Eustatius. Collaboration between not only the six Dutch Caribbean islands but countries across the wider Caribbean as a whole is necessary in order to protect and conserve these essential species and ecosystems. Therefore the Caribbean Shark Coalition was recently formed to collaborate better in the entire Greater Caribbean region.
Celebrated on July 28 each year, World Nature Conservation Day acknowledges that a healthy environment is the foundation for a stable and healthy society. This includes a healthy ocean which, undoubtedly, depends on sharks. Sharks are large top predators that serve a critical role in maintaining balance in the marine ecosystem. Sharks help keep their prey population healthy by eating the weak while also affecting their prey’s distribution. In healthy oceans, sharks help to maintain stable fish stocks and healthy coral reefs and seagrass beds, which is important for the fisheries and the economy of the islands.
The Tiger Shark research expedition is coordinated by the DCNA and generously funded by WWF-NL through the Biodiversity Funds and the Dutch National Postcode Lottery.

Reefs Go Live returns for new season
CCMI brings the ocean directly to classrooms around the world through live-stream lessons from underwater
In 2018, the Central Caribbean Marine Institute (CCMI) launched Reefs Go Live, their innovative, flagship education programme that live-streams directly from underwater on the coral reefs in Little Cayman to students in classrooms around the world in real time. For the 2022 season, the four episodes of Reefs Go Live reached more than 107,000 viewers in 22 countries. CCMI’s Reefs Go Live team hopes to expand their reach with four new episodes and supplemental teaching resources to help integrate the material into classroom lessons.
Science Communications & Development Manager for CCMI, Beth Chafin, is excited to be part of another year of Reefs Go Live:
“Knowing we have an audience that spans the world, our team is energised as we plan and implement our Reefs Go Live season for 2023! We feel that creating a connection to the ocean and sharing the beautiful coral reefs of Little Cayman with others, both locally and abroad, is one of the most important ways to increase support for critical, timely issues such as marine protection and sustainability. At CCMI, we are fortunate to have these stunning reefs at our doorstep; not everyone is so lucky to be this connected to coral reefs, but healthy coral reefs are vitally important to everyone on earth. Bringing the ocean into classrooms and homes through Reefs Go Live allows us to share the work we do at the Little Cayman Research Centre, facilitate real-time interactions between viewers around the world and our experts in the field, and inspire the diverse audience to take positive action for the future of coral reefs.”
The first episode of 2023 will take place on Friday, 31st March at 10 am Cayman time (UTC -5h). The episode, ‘Finding Hope on our Reefs’, will feature what CCMI’s long-term monitoring of Little Cayman’s reefs shows us. The data from the annual surveys reveals important trends in reef health over time that reflect global threats and the benefits of strong local protection. Reefs Go Live hosts will explain why this annual monitoring is important and what the results tell us about the future of our coral reefs that we all depend upon. Viewers of each episode will be able to ask questions of the diver and participate in polls through the online platform to make Reefs Go Live an interactive experience.
Additional episodes for this year will run at 10 am (UTC -5h) on the following dates:
Thursday, 11th May: Adaptation on Coral Reefs
Wednesday, 24th May: Reef Resiliency & Restoration
Thursday, 8th June: World Ocean Day – 25 Years of Coral Reef Research
Registration for Reefs Go Live is free and is only required once to receive access to all episodes: https://donate.reefresearch.org/rgl2023.
Reefs Go Live provides an opportunity for students from all over the world to engage with the stunning ocean environment in its most natural format. As coral reefs around the world face unprecedented pressure, generating increased engagement with these precious ecosystems creates an opportunity to promote marine sustainability in a positive and fun way.
Reefs Go Live utilises streaming technology with underwater video and audio equipment to enable real time broadcasting from Little Cayman’s stunning coral reefs. Little Cayman, a Mission Blue Hope Spot, hosts one of the healthiest reef ecosystems in the Caribbean, which overall remains healthy and shows resiliency to climate change impacts. The broadcasts and education materials draw connections from CCMI’s current research conducted in Little Cayman to the national science curriculum and key ocean literacy principles, making CCMI’s work relevant and accessible to students and viewers of all ages, and emphasizing the relationship that we all have to coral reefs, no matter where we are.
Reefs Go Live is a free education programme that is made possible by the generosity of The Edmund F. and Virginia B. Ball Foundation. To register for the broadcasts and teaching resources, please visit: https://reefresearch.org/what-we-do/education/reefs-go-live/
