“Making a difference out in the field and playing an active role in the protection of our oceans is a rewarding and life changing experience.”
-Andrea Marshall

Most people that love the ocean dream about playing a more active role in education, research or conservation. Who wouldn’t want to get more involved in something that they are passionate about? To that end Dr. Marshall has always encouraged that people take a proactive approach to their travel or ocean hobbies.

Demand from her supporters, combined with the need to fund her international research, has inspired Andrea to create ‘Ray of Hope Expeditions’. Each year the Queen of Mantas and other senior scientists from the Marine Megafauna Foundation embark on international expeditions to the world’s foremost manta ray aggregation sites to engage in field research and conservation.

Explore new aggregation sites with us, encounter mantas in remote destinations, photo-document manta rays for upload to Manta Matcher, participate in research activities, investigate manta ray fisheries and receive lectures from world-class biologists as a part of your package. The goals of each of the expeditions are unique but every trip is tailored to engage participants while producing high quality science. To download the ROHE brochure, click here >
