Overview: Enjoy conservation diving at Cocos Island, one of the world’s top locations for shark congregations. Join a Turtle Island research expedition to Cocos Island and work alongside scientists to research sea turtle and shark populations and migration at one of the world’s premiere scuba diving sites to see hammerhead sharks and a myriad of large marine species. Turtle Island Restoration Network has conducted 2-3 expeditions to Cocos Island each year for more than 10 years. Your research leaders are Turtle Island Founder and Director Todd Steiner, biologist and respected conservation leader, and Randall Arauz, shark advocate and winner of the Goldman Environmental Award. Our research has led to new understanding of sea turtle and shark migrations throughout the region. This diver assisted research will provide the basis for strong protections to stop commercial fishers from invading these treasured waters.

The Research Site: Cocos Island National Park in Costa Rica is known worldwide as an ocean haven for spectacular sharks, rare sea turtles, whales and abundant marine wildlife. These trips offer some of the most spectacular opportunities to view and photograph the incredible marine biodiversity of the East Pacific.

Cocos Island National Park and World Heritage site is located 530 km southwest of Costa Rica’s mainland. Known as one of the world’s most incredible diving destinations, it is famous for its large populations of scalloped hammerhead and white tip reef sharks, and boasts a number of endemic fish that occur nowhere else on the planet.  Cocos Island was recently named the best place to dive with sharks by CNN.  Read the story here.

The Diving: Expedition participants will dive among schooling hammerheads, several species of sea turtles, and schools of thousands of fish, as they support conservation efforts directly at the site. Participate in three fantastic dives each day, which are enhanced through work with Turtle Island biologists to study sea turtles, and census and track sharks. Participants will be able to assist with various levels of research depending on experience. Enjoy engaging conservation lectures and socializing with fellow ocean lovers every evening.

Hammerheads are easily viewed at close range at “cleaning stations,” and inquisitive green turtles commonly approach our dive teams, offering fantastic photographic opportunities and facilitating tagging studies.Other regularly observed species include Galapagos sharks, black tip sharks, silky sharks, marbled rays, eagle rays and bottlenose dolphins. The special treat of any diving expedition–whale sharks–are also occasionally observed. Endless schools of jacks also swarm the island.

Requirements: Divers must be experienced divers, with PADI or NAUI membership, and must have personal DAN insurance. Nitrox is available for certified divers, and certification is also available on the vessel.  The minimum required level of certification to dive at Cocos is Open Water. Please contact us for more information about required certifications.

Most of the action is at 60-90 feet /18-27 meters, and most dives are between 60-130 feet / 18-40 meters. Average temperature is 79 F to 84 F (26 C to 29 C), although it can be a few degrees lower under the occasional thermocline.
