Join researchers in the pristine wilds of Costa Rica to conduct critical research on marine mammals. Your findings may help to develop a permanent marine protected area.


An  volunteer monitors a cetacean’s GPS location.Golfo Dulce, a narrow inlet on the southern Pacific coast of Costa Rica, provides a rich habitat for cetaceans (whales and dolphins). It remains fairly pristine since the many tourists who visit Costa Rica each year haven’t quite discovered it yet—which makes now a crucial time to investigate what the ecosystem needs to remain healthy. By understanding the behavior and tracking the abundance of the marine mammals in this region, we can ensure we have the necessary information to protect them best when tourism starts in earnest in this beautiful, wild place.

For about a decade, this project has gathered information on three species of cetacean in the gulf: the pantropical spotted dolphin, the bottlenose dolphin, and the humpback whale. In studying these cetacean species, researchers hope to understand how to preserve the entirety of this beautiful marine ecosystem.

Through this research and your volunteer involvement, this project will help develop conservation plans to protect the future marine biodiversity in the gulf.

HOW YOU WILL HELP

In this beautiful tropical setting, you will:

.

An  volunteer documents a dolphin’s GPS location, size, and behavior.
MONITOR WHALES AND DOLPHINS

By boat, you will follow groups of dolphins and whales. When someone spots a cetacean, you'll document its GPS location, size, and behavior (e.g., feeding, traveling).

A group of  volunteers follow marine animals to observe and document them.
RECORD TROPHIC WEB

Document and describe the species in multi-predator assemblages by observing aggregations of schooling fish and their predators, such as dolphins, seabirds, sharks, and rays.

A Common bottlenose dolphin (Tursiops truncatus)
PHOTO-IDENTIFY INDIVIDUALS

Back on land, you’ll help sort pictures of each dolphin species so scientists can identify individuals using the unique scars, notches, and other markings on their dorsal fins. The researchers know the dolphins in the gulf exceptionally well, so expect to hear stories about some of their most memorable encounters.

Field conditions and research needs can change the itinerary and activities. We appreciate your cooperation and understanding.

This expedition was a fantastic, once in a lifetime experience! It was really interesting to learn about the potential impacts to the whales and dolphins in Golfo Dulce and how the work that Lenin and David are doing can help reduce that impact. I learned a lot about what they do as scientists and it was really great to feel like I was actually helping to further their research. They are very protective of these dolphins and whales and that was contagious for all of us. Going out on the boat to see the dolphins and whales up close was a highlight - I got a picture of a baby whale with his mouth open! So cute! Also, fishing with the long line was an unexpected fun activity - we caught a small tiger shark, inspected and measured it, then put it back. What other trip would you go on where you could do that?? This was an excellent trip! So glad I went.

I highly recommend this expedition. I loved every minute of it. David was very passionate about the whales and dolphins and Golfo Dulce. He loved sharing his knowledge of this project and how important the research is for the health of the animals and Golfo Dulce. The accommodations in the handcrafted eco-cabins were lovely and the home cooked food was delicious. I enjoyed spending my free time on the porch bird watching or playing cards with other team members.

It was hot, wet work following whales and dolphins in a boat for hours in Golfo Dulce; not to mention catching fish and sharks, especially at night. But the reward of seeing magnificent humpbacks and spectacular bottlenose and spotted dolphins made it all worthwhile. The lectures and supplemental videos provided significant insight into understanding these creatures and their habitat, as well as the food chain and health of this environment. Our efforts hopefully will help this area to become a protected marine ecosystem. Lenin, the PI and David, his associate were very informative and patient in answering our many questions. The accommodations were more than adequate, the family owners and staff accommodating, the food terrific, the showers fairly warm,and there were no mosquitoes despite the plentiful rainfall (after all it is a rain forest). We also enjoyed a local school visit complete with ice cream and soccer, a visit to a wonderful wildlife sanctuary and lunch in the nearby town. Our great team had a lot of fun and more than a few laughs, sometimes even at my jokes. Thanks to all for another great adventure. I've already signed up for my tenth expedition. Ken Dubuque, 8/22/17 team
