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.

As a new retiree, I was looking for an organization that I could become a part of that would keep me active, contribute to a worth while cause, be a learning experience, and be fun. fit the bill and exceeded my expectations. Not only was I able to work in a beautiful country, Costa Rica, be with an interesting group of people, spend each day either on the water observing and collecting data on dolphins, but I learned in an up close and personal way about dolphins and how climate change impacts both the dolphins and their environment. You can learn many things from a book but nothing compares to actually living with what you are studying. So many of the dolphins had been named by the scientists and we were able to recognize some of them by the end of our expedition. We awoke every morning to a serenade by literally hundreds of birds-heavenly!! should be on every ones bucket list.
