Ground-breaking Shark Research conducted in St. Maarten waters

Published

on

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.

Raising Awareness for Scuttle the Cuttle – A Global First in Tackling Microplastic Pollution

Published

on

Addressing the global crisis of ocean plastic pollution, a new innovation is turning the tide—by placing real-world environmental action in the hands of children. Scuttle the Cuttle, a microplastic-collecting tool designed specifically for young users, has been launched as a practical and inspiring way to involve families in beach cleanups.

Crafted entirely from recycled ocean plastic, Scuttle is a cuttlefish-shaped combination of bucket and sieve. Its engaging design, sustainability credentials, and focus on education make it more than just a toy—it’s a tool for change.

Designed for Impact

Scuttle’s core purpose is to help remove microplastics—plastic particles smaller than 5mm—from beaches. With a mesh size of 2.8mm, Scuttle can collect small plastic fragments and nurdles before they degrade further. This addresses a critical but often overlooked part of the plastic pollution problem.

Built for Young Eco-Heroes

Scuttle is ergonomically designed for both children and adults. Lightweight, durable, and easy to carry, it allows even the youngest users to contribute meaningfully to beach cleanups. Its approachable design turns environmental action into a fun and empowering activity for children and families.

Circular by Design

From production to end-of-life, Scuttle reflects a strong commitment to the circular economy. Made from 100% recycled ocean plastic and fully recyclable, it is manufactured with long-term use in mind. The product not only removes waste from the environment but also repurposes existing waste in its construction, reducing environmental impact across its lifecycle.

Community and Collaboration

In addition to its environmental function, Scuttle is part of a broader movement to build awareness and encourage local partnerships. It supports responsible sourcing, local collaborations, and community-driven conservation efforts.

Scuttle is now available for purchase and is positioned as the first product of its kind focused specifically on the collection of microplastics through kid-friendly, hands-on cleanup.

I.CARE, SSI Blue Oceans, and Mares Team Up to Remove Over 36,000 Pounds of Debris from the Florida Keys

Published

on

The 3rd Annual I.CARE Trash Derby has come to a successful close, delivering a powerful message of community-driven conservation. In partnership with SSI Blue Oceans, Mares, and several other industry leaders, I.CARE once again led an inspiring grassroots effort to restore and protect the marine environment of the Florida Keys.

This year’s Trash Derby broke records, drawing support from more than 900 participants—including divers, boaters, and conservation advocates—who collectively removed an impressive 36,459 pounds of marine debris. Over a two-day period, teams worked on land, along shorelines, and at reef sites both above and below the water, making a meaningful contribution to the region’s ecological health.

“I am so proud of everyone involved in last week’s I.CARE Trash Derby,” said Mike Goldberg, Co-Founder of I.CARE. “This level of success comes from the passion and hard work of hundreds of people who care about our oceans, reefs, and local communities. I’m filled with gratitude.”

Recognizing Top Contributors: From Trash to Triumph

The event featured competition across three categories—Land & Shore, Private Boat, and Dive Operator—awarding teams based on the amount of debris collected per person. Additional special recognitions included the most monofilament retrieved and the most unusual item found. Congratulations to the standout teams of 2025:

Celebrating Conservation with Community and Education

The weekend concluded with the Trash Derby Festival at Founders Park in Islamorada. Attendees enjoyed live music, food, and sustainability-focused vendors, all centered around marine conservation. The festival also provided opportunities to connect with environmental organizations and celebrate the participants’ achievements.

“The energy and dedication from everyone involved was incredible,” said Rachael Steidley, SSI’s North America Marketing Manager. “This event goes beyond collecting trash—it’s about building a movement and inspiring conservation on a global scale.”

Looking Ahead to 2026: Raising the Bar

Plans are already underway for the 4th Annual I.CARE Trash Derby, with organizers calling on dive pros, boaters, and ocean advocates to help set an even bigger record next year.
