Cave & Technical Diving

The caves and their exploration can be compared to outer space exploration. They are as remote and as unforgiving as the dark universe, they present dangerous obstacles but incredible rewards. Cristina has been in caves and underground passages where no other man has ever been before. Her extensive work includes exploration of new systems, the connection between systems never achieved before, survey, consulting work to protect specific areas, support of the Bahamas National Trust through her volunteer work and participating in National Geographic Expeditions.


The Bahamas government has committed to protecting an additional 20% of its total territories by 2020. Each island asked interested parties in the contribution towards proposals. Volunteering for the Bahamas National Trust, Cristina completed the exploration and survey work of two major areas, currently submitted for protection approval.

Ben’s Cave survey. Started in 2009 between Cristina Zenato and Arek Pers, later Cristina completed the full survey in 2011 and submitted a proposal for the expansion of the current boundaries of the Lucayan National Park on Grand Bahama Island, to include the full extension of the cave and the land forest and mangrove area.

Sweeting’s Cay Zodiac System. Comprising of seven different caves, first explored by British cave divers, Cristina started to travel to and from the cay to expand the exploration of the systems and survey them. In 2016 she also completed the connection between two systems before attempted but never completed and added several thousands of cave line to the existing passageways. The entire area is a natural habitat for sharks, rays, corals, marine creatures and additional land and mangroves flora and fauna. It has been added to the 2020 proposal.

Additionally, Cristina explored and connected a land-based cave with an ocean blue hole, hailed as the first in history, and used the discovery and data collected from this system to support the request to protect the 2020 project.

Cristina’s work is self-financed and completed on her personal time.

Technical Diving

Gear and special tools are fundamental tools of cave diving and exploration. To benefit completely of their use, training is required to become comfortable and proficient in their applications. Technical diving is an umbrella word including gear configuration, different breathing gases used for different depths, overhead environments real or artificial, a combination of any of these components and added task loading. 

As new technology and new products are showing up on the market it is important to remain updated on the current procedures. 

Both proficient in their use and applications, Cristina uses technical diving as a teaching tool but also a personal tool to expand her work of exploration and conservation. 

She is currently working on the KISS Sidewinder rebreather instructor and learning how to use modern survey systems such as MNemo.
