Combine your passions for ecology and the sea in the port cities of Portugal.

Observe different aquatic species, from starfish to bottlenose dolphins; swim, snorkel, surf, and study the stars at night. Each day you’ll explore a range of fascinating topics related to water resources and aquatic biodiversity as you immerse yourself in conservation and sustainability projects in scenic coastal towns of Portugal, around Setúbal and Lisbon. You will also engage in activities with local peers – playing beach games and sports, performing community service, and practicing your conversational language skills in the most authentic way possible!

Through lectures, field and lab work onsite, you’ll be introduced to Mediterranean natural history, climate, habitats, and sustainability challenges. On side trips to nature reserves and marine parks  you’ll explore both river and ocean biodiversity. Through direct observation and by meeting local communities, you’ll be exposed to sustainability and climate challenges today. In popular vacation destinations, known for their beautiful beaches and sea life, you will observe first-hand and critically discuss how sustainable tourism can help to protect its fragile ecosystems.

These three weeks are all about water, so get ready to get wet! When not kayaking or swimming for fun, you’ll find yourself knee-deep in various river, coastal and maritime ecosystems while gathering and analyzing data with your team. Working alongside marine biologists, conservationists, and sustainability researchers, you’ll develop important skills in a short period of time.
Surveying plants, birds and marine biodiversity in the wild provides invaluable experience and lifelong lessons. Back home in the US, you can apply these insights to future studies on ecology, and spread your message about the importance of long-term sustainability for our society and our planet.

Location & Culture

Sunshine and sea breezes make for pleasant, temperate coastal climates.

With half of its territory bordering the Atlantic Ocean, Portugal is a prime location for this program. It features a pleasant mix of Mediterranean oceanic climate and prime proximity to valuable ecosystems for content studies.

As Portugal is a small country, it's very easy to travel from place to place. It’s also safe, affordable, and friendly. Setúbal, where you will be based for the program, is a beautiful coastal town, only 1 hour south of Lisbon, the capital of Portugal. You can have a full meal for 8-10€ and for 6€ a taxi will take you pretty much anywhere in the city. In Setúbal, you can enjoy beautiful historical monuments, one of the biggest fish markets of Portugal, an amazing shoreline and a dolphin population that adopted its waters as their home!

The best parts of Portugal? Many students name the beaches – among the top places in Europe to go surfing – and the food! Because of the sea, the Portuguese eat a lot of fish of all kinds – grilled, boiled, or roasted. Vegetarian options are gaining popularity around the Portuguese community as well.
