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.

Help protect our marine environment with BSAC’s new Shore Surveyor course
BSAC has partnered with Scottish environmental charity, Seawilding, to offer everyone the chance to help champion the marine environment with the new Shore Surveyor course.
Delivered by eLearning, Shore Surveyor has been designed to engage people, particularly children and young people, in the issues that face our precious marine life. With a focus on the UK’s native oyster and seagrass beds, this eLearning course equips participants with the skills needed to help identify seashore-based habitats and record what they find.
Shore Surveyor is open to everyone, whether they are BSAC members or not.
Working with Seawilding, the UK’s first community-led native oyster and seagrass restoration project, Shore Surveyor participants will also learn about the native oyster and seagrass beds and the issues they currently face.
Both the UK’s native oyster and seagrass habitats have experienced a serious decline over the past 200 years, resulting in an estimated 95% reduction in populations. The new Shore Surveyor course ties directly into BSAC’s major new marine project, Operation Oyster, which aims to protect and restore native oyster habitats around the UK.
By the end of the course, participants can become ‘citizen scientists’ by helping to locate and record seashore areas where current or potential native oysters or seagrass populations are present. This data can then be fed into the National Marine Records Database to help scientists studying our coast as well as support future underwater surveys.
Seawilding CEO, Danny Renton, said he was delighted to partner with BSAC on the Shore Surveyor course.
“Our seas are in peril, and it’s so important to engage families and especially young people, in the wonders of the sea and to engage them in marine conservation. The Shore Surveyor course is the first step to get involved in initiatives like seagrass and native oyster restoration and to nurture a new generation of ocean activists, environmentalists and marine biologists.”
BSAC’s Chief Executive, Mary Tetley, said the new Shore Surveyor course was also part of BSAC’s drive to get more young people actively involved in marine life protection.
“This new course not only explores the threats faced by our precious oceans but also empowers people to get directly involved.
“From a family visit to the beach to a club diving or snorkelling trip, the skills learned on Shore Surveyor can be invaluable to anyone, young or not so young, who wants to make a difference to our under-pressure marine life.”
One of the first participants of the Shore Surveyor course, 16-year-old Lili, from North Wales, has recently put her new found surveying skills into action while on her summer holidays.
“I loved it because it was simple and easy to use and remember,” said Lili. “All ages will enjoy it – young children, teenagers, parents, even grandparents.
“There is a bit of eLearning to do before you start but that is easy to do, and the course really helps you when you go out and see everything for real on the beach!”
Shore Surveyor is open to children aged eight up to adults and costs £20. For more information and to book onto the eLearning course, go to bsac.com/shoresurveyor.

PADI and Seiko Prospex unite to help create the world’s largest underwater cleanup for ocean change
PADI® and Seiko Prospex are teaming up to help marine conservation charity Oceanum Liberandum host the world’s largest underwater cleanup event in Sesimbra, Portugal on 24 September 2022.
Taking place during AWARE Week, the event aims to bring together 700 divers to clean up the coastline for a 12-hour period and is anticipated to host the most divers ever on record taking part in one consecutive underwater cleanup effort. Participating divers and dive centres from around the region will come together to collect marine debris–which will ultimately be logged into PADI’s Dive Against Debris database.
“Our database is the world’s largest in terms of capturing seafloor debris data, which has already helped drive two pioneering scientific papers being used to create new waste management policies,” says Emma Daffurn, CSR Specialist for PADI Worldwide. “More than 250 million tons of plastic are estimated to make its way into our ocean by 2025 and the environmental damage caused by plastic debris alone is estimated at $13 billion US a year. This world record attempt further highlights the important role divers play in reporting, removing and advocating to stop marine debris at its source.”
PADI is proud to have Seiko Prospex on board as the sponsor of the marine debris program and a partner for this world record attempt. Their support is critical to advancing the PADI Blueprint for Ocean Action, and protecting the global ocean now and for generations to come.
“Helping to raise awareness and take an active role in environmental conservation has become one of Seiko Prospex’s missions,” says Miguel Rodrigues, Sales & Marketing Director for Seiko Prospex. “We seek, whenever possible, to support events that have ocean conservation at their core, and we are very honored to sponsor the world’s largest underwater cleanup. We are proud to contribute to a more sustainable future where humans are an integral part of nature.”
Those who want to volunteer to take part in the world record attempt can learn more and sign up at oceanumliberandum.pt/en/Largest-Underwater-cleanup-in-the-World/. The 15 euro registration fee will go towards supporting dive centres with boats, facilities and air bottle logistics.
“We’re thrilled to have the chance to work with Seiko in supporting the largest underwater cleanup event so that we can mobilise Ocean TorchbearersTM to take action to protect what they love, capture more essential data for policy changes, and continue the wave of momentum in creating positive ocean change,” says Daffurn.
