What is Sea Americas?

Sea Americas is a cinematic documentary series following a record-setting all-female dive team as they document climate tipping points, collapsing reefs, historic wrecks, and rare resilience across the Americas from Canada through the United States to Central America and then onto South America.

This is not a diving show.

It is a race to understand and protect what remains of our underwater heritage.

Why it matters now

Every reef we don't document today may not exist tomorrow. These aren't distant warnings. They are happening in real time, in the waters off our own coastlines.

Sea Americas is a line of observation before potential collapse, a record of what existed, and a chance to understand what can still be saved.

Oceans produce 50–70% of our oxygen.
The health of every breath we take begins underwater.
Coral reefs are dying in real time.
Florida Keys. Flower Garden Banks. Disease, warming, and runoff are pushing ecosystems past the point of recovery.
Freshwater acidification is accelerating.
A newly studied phenomenon is spreading through the Great Lakes, threatening ecosystems and human health alike.
Indigenous coastal cultures are losing ancestral waters.
Environmental change is severing bonds between communities and the waters that have defined them for generations.

The technology behind the mission

Underwater, attention is everything.

When you are documenting fragile coral or holding position for a fleeting moment, even small buoyancy adjustments can break focus. For most divers, that constant management is normal. For this expedition, it’s a limitation.

Sea Americas dives using the Avelo System, replacing air-based compensation with water-based buoyancy that stays stable across depth. Movement becomes natural and deliberate. In environments already under stress, that control matters.

Avelo changes how the story can be captured.
