Scuba diving is a fantastic sport, and the accessibility that we have to the underwater world during most Sea|mester voyages is incredible.

Scuba diving is naturally an activity that the majority of our students select to get involved in and, at Sea|mester, it also becomes an important learning tool. Learning about the marine environment while diving the reefs to observe and conduct research adds relevance to our academic studies that’s just not possible in the traditional classroom.

Whatever certification level you are, or aspire to become, the second you take the plunge, the ocean turns into another classroom. Once below the surface, we can study the underwater ecosystems, explore the diversity of marine life and its amazing ecological processes, and even practice conservational techniques we learned about topside.

With an inspiring array of locales ranging from vivid Caribbean reefs to the cold, nutrient-rich and biologically astounding upwelling of the Galapagos Archipelago; seeing, feeling, and experiencing the marine environment makes our studies tangible.

Based on your experience, we teach these courses...

We are affiliated with PADI, the Professional Association of Diving Instructors and PADI is the world’s leader in scuba training education.

We have been rated as a 5 Star Gold Palm Facility, the highest rating that PADI awards, based on our experience, safety standards and commitment to continuing education.

Scuba diving is fun and easy to learn. PADI courses include both academic knowledge development and in water practical training and all are performance-based rather than time-based.

This means that if you are having difficulty with any particular skill, our instructors work one-on-one with you until the skill is mastered.

Just like our sailing certifications, with PADI there is a clear progression in scuba certifications from the Introductory Open Water Course all the way through to Professional Divemaster Certification. Our team of Instructors can teach them all, yet the certification levels that you’ll earn will depend on the length and geographic region of the voyage as well as your previous scuba experience.

As a rule of thumb, our Caribbean voyages typically offer more scuba opportunities than our programs that cross oceans or sail in colder waters.


“The experience is priceless - an absolute once-in-a-lifetime, lifelong impacting program. The confidence I was given through leading sail raises, my time spent in the galley as head chef, leading dives, adventuring on my own during shore time, is something that I will carry with me for the rest of my life. The staff also will forever be role models in my mind - but role models that are also friends. This program and the people on it changed my life.”
Taylor B.
“The last three months has been one of the most amazing experiences of my life. It is not just all the places we see which are incredible or is it even sailing across the Atlantic, which was an amazing feat. But it is the people, the bonds we forged and all the moments that we shared.”
Brian S.
“This was an adventure of a lifetime. Not only did I travel and sail to some of the most beautiful, obscure and amazing places but I have 23 lifelong friends. I can honestly say coming to Argo was one of the best decisions I have ever made.”
Cameron B.
“This program not only opened my eyes to so much of the underwater world that I have never seen before but it also opened my eyes to see the beauty that lies within us all. The relationships that I have made will be with me for years to come. This trip changed my perspective on the world and made me believe that I am capable of anything. ”
