The Mission

To provide exceptional service in marine science education, field-based research training and experience and public outreach in ocean conservation.

We tailor our scientific education services to undergraduates and early career scientists; we provide the training they need to conduct independent projects and collect quality data. Our goal is to present a field-based research orientation that will equip our students with the skills they need to be competitive in the field of marine science.


The Location

Situated in the US Caribbean, Puerto Rico offers a unique learning environment characterized by natural beauty and representative of island biogeography.


The Future

We will continue to grow and expand our services in Puerto Rico, and to other neighboring islands.
