Fins Attached



Citizen Science Research Expeditions

Fins Attached conducts research expeditions throughout the year. Some of these trips are open to donors of Fins Attached. The expeditions allow donors to be involved and participate in shark research to see how their donations are being used to study and protect sharks and our marine environment. We have found that these experiences completely transform the perceptions that individuals have about and towards sharks.

Fins Attached is a US based 501(c)(3) non-profit. All donations given by participants is used to support the research and conservation efforts of Fins Attached and their partners.

2019: Fins Attached – Bahamas Dive Research Expeditions


Fins Attached has partnered with Beneath the Waves and Dr. Austin Gallagher to conduct research in the Bahamas. These expeditions give citizen scientists the incredible opportunity to assist with cutting edge research being done in one of the world’s largest protected area for sharks – the Bahamas.  Every expedition will support Dr Gallagher’s ongoing research in the region, as we explore some of the sharkiest waters of the Bahamas, looking to deploy acoustic transmitter tags on tiger and reef sharks supporting the long-term study on shark survival in the sanctuary. We will also explore the depths of the Tongue of the Ocean looking for new species and behaviors, and will explore some new tiger shark hot spots.  

Expedition Aims 

  • Explore and tag tiger sharks around north-eastern New Providence Island, which may be a new hot spot in the Bahamas for tiger sharks. 
  • Implant reef sharks with acoustic transmitters on the southern wall of the island. 
  • Dive with reef sharks around the southern wall of the island. 
  • Explore the depths of the Tongue of the Ocean and the northern trench of the island, looking for new species and searching for tiger sharks that are known to hang out in the deep; with the aim of understanding what they are doing and why.
