As we move beyond the critical phases of this past year’s global crisis, we have established our in-person field protocols for the 2022 season, and beyond.  We strongly advise that you obtain a COVID-19 vaccination before joining any of our expeditions. This is to protect the local participants and guides, as well as yourselves.

Join MarAlliance’s team of marine biologists, guides and fishers for an unforgettable expedition researching sharks, rays and turtles. Experience the life of a tropical marine field biologist while helping us collect invaluable data that will contribute to the conservation of these vital species.
We will train you so that you can be directly involved in each aspect of our field work from conducting in-water surveys while snorkeling Caribbean reefs, to launching and reviewing the unexpected results of underwater camera traps, to setting longlines to capture, measure and tag sharks and rays. As an expedition volunteer, you will be immersed in the team and contribute directly to the critically-important long-term monitoring of sharks, rays and turtles in key Caribbean sites and Cabo Verde.
