Mr Godson has followed Titanic discoverer Dr Robert Ballard's ocean explorations for the past two decades and now he is among 22 educators to take part in the Nautilus Education Program aboard Dr Ballard's ship of exploration.

As a science communication fellow, Mr Godson will join the exploration vessel as it explores the Mesoamerican Reef off the coast of Belize and Honduras in July and August.

"It is a dream come true to be finally doing what I love doing but in a lot more organised formal capacity," he said.

Mr Godson has spent one month living underwater, propelled himself through the Greek islands in a human-powered submarine and holds the Guinness World Record for the most electricity generated by pedalling underwater.

The Port Macquarie adventurer continues to work towards a stint living underwater in a Danish-designed futuristic sphere.

Aboard the Exploration Vessel Nautilus, Mr Godson will be a link between the public and the scientists and engineers.

There will be live interactions with shore-based audiences via a web portal bringing expeditions from the field to future explorers on shore using technology at www.nautiluslive.org and via social media.

The expedition will map the sea floor using multi-beam sonar, generate maps and scientists will identify points of interest which will be explored further using remotely operated vehicles.

"It is completely exploratory, which is really cool," Mr Godson said.

"It's those few moments when you see things that have maybe never been seen before - that is what you have been hanging out for."

Mr Godson will talk about the exploration programs at schools before he leaves, and encourages schools to log in in during the expedition.

He is committed to encouraging more young people to pursue studies in the science, technology, engineering and maths fields.

Ocean Exploration Trust executive vice-president and expedition leader Dr Katherine Croff Bell said one of the major goals of the Nautilus Exploration Program was to inspire the next generation of explorers in the science, technology, engineering and maths fields.

Mr Godson's role continues back on land when he will bring the excitement of ocean exploration back to the Hastings.

People can follow Mr Godson at www.nautiluslive.org while he is aboard the vessel or go online anytime funtil October 9 for live streaming of the exploration and discoveries.
