Field Courses

Experiential field courses that bring together students, educators, scientists, and communities to learn from island and ocean ecosystems.

The original field course company in Puerto Rico

We have been designing and leading field courses on the island since 2015. Every session is taught by Drs. Chelsea and Evan Tuohy, PhD marine scientists who have spent more than a decade researching these ecosystems. When you book with us, you get us.

Real science, not a demonstration

Participants run transects, identify species, take water quality measurements, and contribute observations to a monitoring dataset we have maintained for years. Let's do some science!

One connected system

We begin in our backyard at the marine reserve to learn about coral reefs, follow through to seagrass and mangroves, and finish in the mountains for a full Ridges to Reefs experience. Few places let you teach the whole gradient in a week. Puerto Rico does.

Ridges to Reefs Adventure

Stay tuned for the 2027 dates with our partner the Oceanic Society. This trip will take nature lovers on a scientist-guided exploration of many of the diverse ecosystems of the island.

Caribbean Reef Fish - Citizen Training

Stay tuned for 2027 dates with partner the Oceanic Society. This trip will give explorers the first hand encounter with Caribbean reef fish identification and fish biology and ecology.

Ridges to Reefs - High School Edition

Stay tuned for 2027 dates with partner Students Shoulder to Shoulder. This trip will give young explorers a scientist's perspective with hands-on field experience to connect the land and the sea.

Let's do some science.

Most of our courses run with partner organizations who recruit their own participants — universities, graded schools, conservation nonprofits, and educational travel programs. You bring the group; we deliver everything that happens in Puerto Rico. 

Palm trees
Coral Reef Biology

Learn about the coral reef ecosystem from tiny polyp to fringing reef tract.

Ridges to Reefs

Discover the connection between land and sea, especially obvious on an island.

Field Techniques

Learn how to monitor coral reef health, study fish communities and more.

Coral Reef Fish

Explore the world of Caribbean reef fish with specialized ID training and practice surveys.

Educator's Course

Most science teachers explain marine ecosystems they have never worked in. This program sends them home having run the transects themselves and gained first hand experience in the habitats. No marine science background or SCUBA certification needed; all in-water work is snorkel-based.

Built for districts, independent schools, teacher PD programs and science teacher associations who recruit their own cohort.


You bring the group, we handle everything on the ground. Contact hours documented for professional development funding.

Send us your group size, preferred window, and what you want participants to come away with. We will return a full proposal with a day-by-day itinerary and costs estimate.

Dates for the following season are typically held by returning partners before we open the calendar, so earlier is better.
