Join Us

Our expeditions combine science, design, and frontier technologies to experience, understand, and share beautiful and threatened ocean environments, especially coral reefs. Participants are invited to join the Hydrous community of scientists, educators, tech professionals, divers, and creative minds to learn together, share adventures, and find solutions to some of the world’s most pressing problems. Since 2014, the Hydrous has explored marine ecosystems in California, Hawaii, Easter Island, Palau, Japan, Guam, Indonesia, Solomon Islands, Belize, and the Maldives (flagship destination).

Dec 9-16, 2017

Map coral reefs with our 3D methodology, learn how to conduct scientific surveys, and improve your underwater photography skills! We invite you to explore some of the most beautiful coral reefs in the world onboard a luxury dive charter and to become part of the worldwide Hydrous community of scientists, designers, big-thinkers, and problem-solvers.  

Why the Maldives? 

The Maldives are comprised of 1,200 islands and atolls in the Indian Ocean. Many of the islands lie just about 1 meter above sea level (to put this into perspective, a dolphin can jump almost 8 meters high), making them vulnerable to many challenges brought on by sea level rise and climate change. The benefits of coral reefs reach us thousands of miles away in the oxygen we breathe to the food we eat, but the distance can make these islands seem ‘out of sight, out of mind.’ These islands contribute a fraction of global greenhouse gas emissions, yet they are among the first to suffer from the effects of climate change. We work with our counterparts in the Maldives to collect footage and bring to light the crises the Maldives face so we may be able to act effectively and experience the beauty and value of coral reefs and oceans for years to come.
