Ground-breaking Shark Research conducted in St. Maarten waters
In April 2021 members from the Nature Foundation St. Maarten, the Dutch Caribbean Nature Alliance (DCNA), the Saba Conservation Foundation (SCF), and Beneath the Waves conducted multiple ‘scientific firsts’ as part of the “Shark Shakedown” project. The research expedition was a part of a wider research project into tiger sharks in the region funded by World Wide Fund for Nature (WWF-NL) through the Biodiversity Funds and the Dutch National Postcode Lottery. The researchers tagged eleven sharks, including for the first time a female pregnant tiger and endangered Caribbean reef shark in the Dutch Caribbean. The data will provide vital information for conservation strategies not only in St. Maarten, but for the wider Caribbean.
The expedition lasted five days in which three species of sharks were tagged, including tiger sharks (Galeocerdo cuvier), Caribbean reef sharks (Carcharhinus perezi), and nurse sharks (Ginglymostoma cirratum) all ranging from sub-adults to adults.
Participants received hands-on training with experts from Beneath the Waves in preparation for the upcoming expedition to the Saba Bank in August 2021. The goal of this upcoming expedition is to determine whether the Saba Bank is a breeding area for tiger sharks in the Eastern Caribbean. The high-definition ultrasound technology the team used was created by E. I. Medical Imaging and pioneered by collaborator Dr. James Sulikowski, of Arizona State University. This technology has successfully been used to identify maturity state and the stage of pregnancy in various shark species, a first for shark science in the region.
The scientists successfully confirmed early pregnancy stage in a large female tiger shark, as well as placed a satellite tag on the shark during the workup process. Using satellite tracking over the next few months, the scientists hope to confirm evidence of Sint Maarten being a breeding location for these globally threatened animals. In another shark tagging ‘first’, Beneath the Waves’ Chief Scientist, Dr. Austin Gallagher, placed the first camera tag on a tiger shark in the Dutch Caribbean. The team successfully recovered the camera package during the expedition, and the animal has already shown promising results regarding shark behavior in the region.
Both the satellite tag and camera tag have shown that these tiger sharks prefer to travel in the area between St. Maarten and St. Barths; however, these are only the first detections. No assumptions can be made yet regarding the movement of these animals.
The information gained from this research will provide a better understanding of the importance of both the status of sharks in Sint Maarten’s territorial waters and in the Yarari Sanctuary and the role these ecosystems play in the life-cycle of tiger sharks in the wider Caribbean region. Tiger sharks are currently categorized as Near-Threatened by the International Union for Conservation of Nature while Caribbean reef sharks have very recently been upgraded to Endangered. Sharks play key roles in maintaining the balance within local and regional marine ecosystems and maintaining biodiversity and therefore their protection is crucial.

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/
