Looking for an unforgettable dive adventure this summer? A shared male space has become available on both of REEF's upcoming Field Survey Trips, giving you one last chance to join fellow ocean enthusiasts on an incredible week of diving and citizen science. Additional spaces on Tobago are also available.
Tobago August 1–8, 2026
Tobago's nutrient-rich waters, influenced by the Orinoco River, support some of the Caribbean's highest fish diversity. During REEF's most recent trip, participants documented more than 200 fish species, with many surveys recording 60–70 species on a single dive. Divers encountered southern Caribbean specialties including the Yellowcheek Wrasse, Yellowtail Reeffish, Jaggedhead Blenny, Saddle Parrotfish, and more. If you're looking to expand your life list with species rarely seen elsewhere in the Caribbean, Tobago is the place to do it.
Midriff Islands, Sea of Cortez September 12-19, 2026
The Midriff Islands are the heart of Mexico's legendary "Aquarium of the World," where nutrient-rich waters and dramatic volcanic reefs support an abundance of marine life found nowhere else. On REEF's previous expedition, surveyors documented Gulf of California specialties including the Cortez Angelfish, King Angelfish, Leopard Grouper, Mexican Hogfish, and Yellow Snapper, while also enjoying encounters with California sea lions, dolphins, mobula rays, and even whales. It's an exceptional opportunity to survey species unique to the eastern Pacific while diving in one of North America's most productive marine ecosystems.
Dive, Learn, and Make a Difference
Both expeditions combine world-class diving with daily fish identification seminars and hands-on citizen science. Whether you're a seasoned REEF surveyor or completing your very first survey, you'll sharpen your fish ID skills while collecting data that supports marine science and conservation.
