Three unique trips

May & November 2023 … August 2024


Majestic Cocos Island in Costa Rica is offers hammerhead sharks galore. A place of pure diving pleasure but also of intense scientific value. Are you an ocean enthusiast interested in the science behind sharks? A diver with a heart for conservation? Then don’t miss out on these three spectacular trips!


THE EPICENTRE OF SHARK DIVING


Very often diving destinations are awarded with accolades, and in the case of Cocos Island every single one of them is true. The marine life surrounding this mysterious island in the Pacific, is truly spectacular and unique. 

Cocos represents a myth for divers. Everyone who has heard of Cocos wants to go there, while everyone who has been there before wants to go back. It’s a stellar and unbreakable reputation not a lot of other dive destinations can compete with. 

During this 10-night cruise, 7 days of diving are planned at Cocos Island. You can expect sharing the water with schooling hammerheads, silky sharks, Galapagos sharks, sand tiger sharks, and yes: even a tiger or two. 

COCOS SP EXP MARINE LIFE

But let’s not forget Cocos is so much more than swirling sharks. You’ll enjoy the many turtles and countless brightly coloured fish, the eels & lobsters & octopus and many other critters residing in the hard coral reefs. There are marble rays, manta & eagle rays floating around, and who doesn’t love encountering a whale shark in the deep? There are lots of schools of pelagic fish and bait balls passing through these waters as well. The diversity is really just mind-blowing.

If you’re an experienced diver who loves adventure, Cocos is not to be missed. Its beauty is not limited to underwater either. You’ll have an opportunity to access the island to explore the verdant beauty and impressive waterfalls as a nice change of scenery from the underwater world. 


SHARK SCIENCE AND CONSERVATION


This expedition offers an excellent opportunity for shark conservation enthusiasts and early career scientists who want to become acquainted with shark research field work in one of the sharkiest places in the world.

During the dives, researchers will tag sharks underwater using a pole spear to attach an acoustic transmitter. The pole spear anchors a dart under the shark’s skin, right under the dorsal fin. The tag is tethered to the dart by a steel cable, and dangles as the shark tows it. We may also change the tip of the pole spear and instead of a dart we use a tissue sampler, which works like a cookie cutter, punching a hole in the shark’s skin to obtain a sample the size of a bean. There will be focus on hammerhead sharks, galapagos sharks, blacktip sharks, silvertip sharks, tiger sharks, whale sharks, manta rays and eagle rays.

There will also be active shark fishing in order to implant acoustic tags surgically. This activity is done at 5:00 am and 5:00 pm, for two hours.

Any turtles encountered will be caught underwater and brought to the deck of the liveaboard, where they will be measured, weighed, photo-catalogued, tissue sampled, and tagged with external Inconel flipper tags.

This is truly a once in a lifetime way to learn the latest science and the policy changes needed for efficient shark conservation in the Eastern Tropical Pacific while diving the world’s most famous dive sites.

GETTING THERE, WHAT’S INCLUDED, WHAT’S EXTRA & RATES


This trip leaves from Puntarenas, Costa Rica …. a 3-hour ride from San Jose.  Costa Rica has two international airports. For optimum convenience, we recommend that you fly directly to San José rather than the more distant Liberia International Airport. 

ARRIVING & DEPARTING

All yacht departures are from Puntarenas, Costa Rica.  Guests need to arrive the day before the charter start date and overnight in San Jose, Costa Rica. You may choose to stay at one of the recommended host hotels (Holiday Inn Escazu or Holiday Inn Express Forum) or at another hotel of your choice.  Please note that pick-ups for transer to the boat are only from these two hotels.

You will be met by an Aggressor representative on the day of departure at a pre-set time for the group transfer.  Boarding depends on the tide schedule. Immediately after boarding the yacht departs for its crossing to Cocos Island. The crossing takes roughly 36 hours and you can expect to arrive at the island around dawn on Day 3. After a full seven days of diving, the Okeanos Aggressor II returns back to the dock in Puntarenas and you will be taken back to San Jose.

If you’d like to add on a few days in Costa Rica’s outstanding rainforest parks, we’ll be happy to help you with that.
